Security computer screen: Why Do I Need a Computer Privacy Screen?


Why Do I Need a Computer Privacy Screen?

Cybersecurity threats are not something to be taken lightly. While most computer users are familiar with common cybersecurity threats such as phishing, password attacks, and malicious software, few are aware of the dangers of visual hacking.

As the name implies, visual hacking refers to prying eyes attempting to steal your on-screen information without you ever noticing. Computer privacy screens help protect against visual hackers and keep your sensitive information confidential.

With the growing amount of data breaches and malware attacks each year, PC users, small business owners, large companies, and global enterprises alike are all strengthening their security measures to combat cybercrime.

The rate of hacker attacks is near-constant, occurring every 39 seconds on average and affecting one in three Americans every year [1]. No one is impervious to a determined cybercriminal, especially on computers used at unsecured locations.

Here we’ll discuss the importance of computer privacy screens, what they are, how they work, and why you should invest in one to safeguard your confidential information.

What is a computer privacy screen?

A computer privacy screen, sometimes called a privacy filter, is a thin piece of plastic that’s placed over your monitor or display panel in order to prevent wandering eyes from absorbing confidential information.

You may have seen a similar device at the bank if you’ve ever tried to peek at your account balance when the teller walked away. Privacy filters use the same type of technology.

Strong passwords, anti-virus software, data encryption, and heightened awareness go a long way toward keeping your information secure, but they can’t defend against visual hacking.

Computer privacy screens protect against this serious security threat by simply adhering to your laptop screen or desktop monitor to restrict the device’s viewing angle so that only the person in front of the screen can see what’s on it.

Anyone attempting to steal a glance from the right or left will only be able to see a blank screen.

How does a computer privacy screen work?

If you’re not sure how privacy screens work, think of them as similar to vertical blinds, which can only be seen through when they are turned at a certain angle.

Computer privacy screens work the same way but on a much smaller scale, severely restricting viewing angles to the point where you essentially have to look at the screen straight on in order to see the display.

The tiny polarized blinds, sometimes known as micro louvers, make it so that the contents of your computer screen are visible to you but not the person lurking to your left or right.

The thinner the blind, the more that light can pass through for the intended user. A polarized plastic sheet uses the same technology in privacy filters as used in polarized glasses, in which an optical filter blocks out light from certain angles.

Depending on the make and model, privacy screens usually start to block visibility at around a 30-degree side angle and may appear blacked-out near a 60-degree angle.

Why do I need a computer privacy screen protector?

Many digital users worry about their online activity being monitored or spied on digitally by their boss at work, their internet provider, or even by government agencies.

Regardless of whether or not these concerns have merit, it’s important to remember that spying doesn’t have to happen digitally. The low-tech means of snooping is equally effective: watching over your shoulder.

Privacy in the workplace

Visual hacking is a very real threat. In fact, 3M recently conducted a global experiment on visual hacking and their dangerous findings were eye-opening [2].

Here are a few of the key takeaways from their worldwide results on the importance of visual privacy in the workplace:

1. Visual hacking is easy. In the global trials, a white hat hacker was successfully able to visually hack information 91% of the time.

2. It happens quickly. In nearly half of the trials, an undercover visual hacker was able to glean information in 15 minutes or less.

3. It goes unnoticed. The visual hacker was only stopped in 32% of global trials.

The findings from the 3M study are alarming. It takes between a few seconds and a few minutes for a passerby to glance at a computer display and glean sensitive information which could later be used for malicious purposes.

Most of the time, this security breach goes undetected. If it happens to you, you might not be aware until it’s too late.

Various forms of information are vulnerable to visual hacking in both onsite and remote work environments. While you may want to give everyone the benefit of the doubt, the truth is, unfortunately, that the stranger sitting to your right on a train or the custodian walking past your door should not be trusted.

It’s your responsibility to protect your company’s private information especially if you’re a small business owner, since 43% of cyber attacks are targeted at small businesses and 60% of these small companies go out of business within six months of an attack [3].

Multiple types of business data are at risk of visual hacking without a computer privacy screen, including things such as:

1. Trade or marketing secrets

2. Proprietary data

3. Payroll or bank statements

4. Customer or employee information

5. Privileged email correspondence

6. Contact lists

According to Juniper Research, the average cost of a data breach in 2020 will exceed $150 million [4]. That number could be the end of a small business, especially when compared to the inexpensive cost of a computer privacy screen which may have been able to prevent a security breach in the first place.

Privacy for personal computing

Even if you don’t use your laptop or desktop for work purposes, you may still inadvertently display your own confidential personal information to a visual hacker via:

1. Online bill payments

2. Address submission forms

3. Password logins

4. Email communication

The consequences of this sensitive information getting into the wrong hands can be as mild as annoying junk mail and telemarketing calls, or as severe as life-altering identity theft.

According to a survey conducted by The Harris Poll in January 2018, nearly 60 million Americans have been affected by identity theft. That’s a dramatic increase from 2017 when a mere 15 million people experienced identity theft [5].

With everything from tax fraud to bank fraud, phone fraud to utility fraud, identity theft is clearly on the rise. Although corporate data breaches can expose your personal information and leave you vulnerable to a cybercriminal, low-tech visual hacking is equally dangerous.

A computer privacy screen is an easy step you can take towards tightening your security measures and keeping your confidential information out of sight from prying eyes.

Cyber threats aside, sometimes PC users want privacy just for privacy’s sake. It may be in our nature to take a curious glance at the device of the person sitting next to us, but some people prefer to keep their business to themselves, even if there are no high stakes involved.

In that case, a computer privacy screen protector can prevent strangers nearby from knowing what movie you’re watching or websites you’re surfing.

In addition to peace of mind against visual hacking and personal snooping, many monitor privacy screens also offer anti-glare properties to enhance your viewing experience along with protection from dust and scratches.

They are easy to apply, remove, and clean, plus most models are affordable. All things considered, investing in a privacy screen is a worthwhile consideration.

How do I find the right computer privacy screen?

Most people purchase a computer privacy screen protector as an aftermarket add-on. HP® offers an assortment of laptop and monitor privacy screens, including models made by 3M and Targus®.

Some options you may want to consider include:

1. HP 15.6-inch privacy filter – Designed for use with non-touch screens, this computer privacy screen efficiently inhibits a direct view of your screen from anyone else but you, while maintaining your screen’s crystal clarity. It also resists scratches and glare.2. 3M 13.3-inch gold privacy filter – With this 3M computer privacy screen protector, you see clearly while people on either side of you see a vivid gold screen. The filter is reversible, and the lightweight, thin, frameless design protects against dirt, debris, and scratches.3. Targus 14-inch laptop privacy screen – This screen features tiny blinds that restrict the monitor’s viewing angle to 45-degrees from the center of the screen. It’s designed for LED filters and is easily applied with included tab guides that stick to the bezel, which may also be positioned along the sides to simply slide on and off.

How to apply a computer monitor screen

Before purchasing your filter, make sure to cross-check the dimensions to guarantee it will fit seamlessly onto your device. Be very careful when using a ruler to measure the diagonal distance across your screen, taking extra caution not to scratch your device in the process.

To avoid this risk, you can also research the specs of your laptop or desktop by looking up the manufacturer’s specifications.

Note: In addition to laptop and monitor privacy screens, you can also find filters sized to your tablet and smartphone. You never know when someone may attempt to steal your confidential information, so if you consistently use smaller devices with sensitive data in high-traffic areas, you might want to take this additional security measure.

After purchasing a privacy screen specified to the dimensions of your device, follow these tips for the best application:

2. If you’re installing a computer privacy screen with mounting tabs, separate the tabs and remove the protective film from each side. Neatly attach the tabs to the sides of the monitor, remove the protective film from the screen, and slide it into place. For screens with adhesive tape, carefully apply the adhesive along the sides of your display, remove the protective film from the screen, and apply to the adhesive tape.

3. When you need to remove or clean your privacy screen, remove it by pulling the tabs on the adhesive corners very gently. Clean it with a microfiber cloth to remove dirt and dust. Make sure the monitor is clear of debris before reapplying.

Note: The exact instructions for installation may vary by manufacturer and design. Please consult the packaging material and manufacturer before applying your computer privacy screen.

Integrated privacy screens

In today’s digital world, you can now find computers with a laptop privacy screen built in, so you would not need to purchase an additional filter to conceal your display content. With an HP Sure View integrated privacy screen, you can quickly and conveniently toggle between turning the privacy filter on and off.

It allows you to watch movies on a plane in beautiful resolution with your seatmate, then hit the F2 function button to restrict your viewing angle if you ever receive a sensitive, inbound work email mid-flight.

If you’re looking for a computer with a laptop privacy screen pre-installed, the HP EliteBook x360 is a standout choice. Modern business professionals on-the-go demand the highest security standards to protect their remote work and the HP EliteBook x360 delivers in spades.

In addition to a Full High Definition touch display with an integrated privacy filter, you’ll be protected end-to-end with extra security features, such as:

  • Fingerprint authentication and facial recognition for Windows™ Hello
  • Preboot authentication
  • Security lock slot
  • Absolute persistence module
  • Microsoft® Defender
  • HP BIOSphere
  • HP SureStart
  • HP Secure Erase

Remember, visual hackers only scratch the surface of the list of potential cyber attacks you may fall victim to. If you practice safe online habits and remain vigilant to emerging threats, cyber criminals near or far won’t stand a chance.

Screen Privacy: How to Protect Yourself from Visual Hacking

Screen privacy is a major concern when dealing with sensitive data, and it’s a problem we don’t think enough about. It is surprisingly easy to steal visible data with low-tech visual hacking techniques. Luckily, there are a number of actions you can take right away to resolve data vulnerabilities. Also, you’re not going to want to miss the deep dive into one of the most effective tools: privacy screens for your monitor.

Keep reading to learn everything you need to know about screen privacy. Or learn more about ViewSonic’s advanced screen privacy filters.

Screen privacy is a problem in an increasingly data-driven society. From online banking and business transactions to social media and personal communications, we access a huge amount of sensitive information through our screens. But have you ever wondered who else is also looking? 

With all the modern focus on cyber-security protecting us from online threats, it’s easy to forget the low-tech security vulnerabilities like what people can physically see on your display or important documents you have just lying around. 

Why Is Screen Privacy Important?

To be honest, there are many contexts in which screen privacy is completely unnecessary. Your home computer probably doesn’t need to secure visual data. Nor does a screen in a small team of trusted colleagues in a windowless room. 

But if you work in a public space – either in the general public or at a large organization – then securing the content on your monitor becomes an essential security measure. You never know who is watching (or recording) your work. And if you’re not protecting your data from prying eyes nearby, you’re opening up very dangerous vulnerabilities for you and your organization. 

Moreover, visual data protection becomes unavoidable if you regularly work with confidential data like medical records, financial transactions, or clients’ work protected by non-disclosure agreements. Think about how much personal data is displayed on a typical nurse’s station or bank teller’s computer. If you work in these roles, it’s your responsibility to protect your others’ sensitive information as well. 

You need to protect data from visual hacking.

What is Visual Hacking?

Visual hacking has to be one of the lowest-tech ways to steal information. (It is only slightly more complex than just stealing a paper document off a table.) However, being simple doesn’t mean it isn’t dangerous. A shocking experiment by the Ponemon Institute (see here for more) showed just how vulnerable office environments are social engineering hacks, especially visual hacking. 

At its simplest, visual hacking involves just seeing information on a screen and remembering it. Given the prevalence of smartphones, however, it’s not hard to snap a photo or record a video under the pretense of checking a text message. A pretense may not even be necessary. Are you really aware of what everyone is doing on their devices around you at any given time? Did you just look over your shoulder now?

Despite its simplicity, visual hacking poses real risks of a data breach and you need to be on guard.

What Can I Do to Improve Screen Privacy?

There are plenty of solutions for reducing visual hacking and improving screen privacy. They vary in complexity and not all are universally applicable. 

  • Use partitions or walls around screens. Open office floor plans make visual hacking much easier. Cubicles and offices make it much easier to keep visual data safe by blocking both displays and hard copies from view. 
  • Turn screens away from public view. Whenever possible, keep your displays facing away from public thoroughfares and high-traffic areas to limit exposure.
  • Make sure to turn unattended displays off. Whenever you step away from your computer, remember to put it to sleep behind a password-protected login. 
  • Keep your desk clear of sensitive documents. Visual hacking targets more than just screens. It can also target paper documents and information. At a minimum, make sure any folders, documents, or notes containing sensitive information are put away.
  • Get a privacy filter for your computer screen. This is the single action that will do the most good in securing your work from unwanted attention. It is a hardware solution that is easy to implement then maintain with no input besides installation.

What is a Computer Privacy Screen Filter?

A computer privacy screen filter is a thin layer of polarized plastic that significantly reduces the viewing angle for your screen. Ideally, this means that the view of your screen is perfectly clear for you as the user while others off to the sides only see a dark screen. All your visual data is hidden unless you are looking at the screen head-on.

A privacy filter for a monitor is a thin layer of high-tech plastic – usually polycarbonate or acrylic – that combines an anti-glare coating with angled slats or panels with the material’s structure. The results are allowing light to pass through the plastic layer at only certain angles. Non-ideal angles either block the light entirely or only emit a single color of light. 

Besides turning off your screen entirely, screen privacy through one of these monitor filters is one of the best ways to safeguard yourself from visual hacking.

How Do I Use a Privacy Screen?

A privacy screen is functionally just a screen coating that blocks the light from certain angles. There are a few different ways to install one, however, and each has its own use cases.

  • Hangers sometimes fix the screen to a monitor or laptop. This makes the filter easy to add and remove. This is a good option for people who sometimes have to collaborate with others and will, therefore, need to periodically remove the privacy filter. Additionally, this version is useful if the plan is to share privacy filters among several devices.
  • Stick-on tabs are a more permanent way to get screen privacy. The tabs are permanently stuck to the monitor, but the filter itself is removable. This is also a good option for people who have to collaborate without a privacy filter. It’s not as shareable, however, as the tabs are stuck to your device. 
  • Permanent adhesive is an option for use cases that always need extra protection from visual hacking and unwanted attention. Like a phone screen protector, this option is permanently glued to your display and cannot be removed or shared. However, it is a handy set-it-and-forget-it option.

Once your privacy screen is installed, however, it will automatically work to reduce the visibility of your screen to anyone outside the optimal viewing angle. 

It’s worth remembering, though that there is not a hard line between visible and hidden, so certain viewing angles will still be able to see some of your screen’s content. 

Can I Trim a Privacy Filter?

In short, you can cut a privacy filter down to the desired size. It’s not the best course of action, though as there are a variety of sizes available and it’s likely that you can get the size you need right out of the package. If you either can’t or don’t want to find the right size, you can still cut a filter down to size.

It’s also very important to be very careful in cutting your privacy filter. A good one can be pretty expensive, and scratching or damaging the screen protector will typically void the warranty. Likewise, cutting into a polarizing layer could throw off the image quality. 

If it’s absolutely necessary to cut your privacy filter to fit your screen, make sure to measure carefully and use both a very sharp utility knife and a straight edge to make the cut. (You can learn more here.)

How Do I Remove a Privacy Screen?

As mentioned above, if you plan to add and remove your privacy screen periodically, you’re going to want to go with an attachment option that allows for that. If you’ve opted for the permanent adhesive version, however, it will likely be much more difficult to remove. 

The process is much like that of removing a tempered glass screen protector, which you can learn more about here.

So Is Anti-glare the Same as a Privacy Screen?

While most privacy screens include anti-glare coatings, not all anti-glare screens have privacy filters. It’s mostly a matter of convenience: it’s not that difficult to add a basic feature like anti-glare to a privacy screen. 

Since privacy features often increase the price of the screen filter, be sure that it’s what you’re actually looking for. If anti-glare is enough for you, there’s no point paying the premium for a privacy filter for your monitor. On the other hand, if privacy is the goal make sure that the filter you’re looking at has al the necessary features to hide your display from prying eyes.

What is the Best Privacy Screen Filter for Monitors?

To get the best screen privacy for your visual data, you’re probably going to look for a few key features. These will help you get the most protection with the least effort. 

Easy Installation

To make things simple, make sure that the privacy filter is easy to install. (And also make sure it’s easy to add or remove if that’s what you’re going to be doing.)

Small Viewing Angle

Since the goal is screen privacy, make sure that whatever screen filter you use has very limited viewing angles. For example, ViewSonic’s VSPF series has a viewing angle of just 60°. 

Minimal Effect on User Experience

While we want to make sure others can’t see the screen clearly, it’s important that the privacy screen doesn’t affect the user’s experience. A high-quality privacy filter screen protector will have virtually no impact on display quality.

Final Thoughts on Screen Privacy

Screens now play a leading role in every element of our lives from work to play. We have TV screens in our living rooms, monitors on our desks, and smartphones in our pockets. But we need to remember that our screens are mixed blessings. Without taking proper precautions, our displays represent real vulnerabilities for data theft. 

With just a few screen privacy best practices – including a good privacy filter on especially vulnerable devices – we can keep all of our sensitive data safer from visual hackers and other low-tech bad actors. Just a few basic precautions can make a world of difference.

Lock Your Computer Screen

Why should you lock your screen when you’re away?

This helps prevent others from viewing or using your device when you’re not around. Set up your computer and mobile devices to automatically go to screensaver after a certain amount of inactivity.  In addition, manually lock when leaving your device unattended.

(Back to Minimum Requirements Main Page)

What should you do?
The following are REQUIRED* for devices that store or access P2 or higher data and strongly recommended for all other devices.

  • Set your device to automatically go to screensaver when you’re not using it (max. 15 minutes of inactivity, max. 10 minutes for HIPAA workstations).
  • Make sure you have to enter a strong password to start up or wake-up your computer.
  • Disable auto-login. You shouldn’t be able to start up or wake up your computer or other devices without entering a password. If you can, auto-login may be on.
  • Manually shut down, log off, or lock your device before leaving it unattended.
  • To lock your device:
    • Windows PC
      • Ctrl-Alt-Del → Select Lock OR Windows Key + L
    • Mac
  • For Mobile Devices:
    • Set your device to require a strong password/PIN to start up or resume activity, and to automatically lock when not in use–but still don’t store anything you’re not willing to lose.
    • Some devices can be set to be erased remotely, or to erase themselves if the password/PIN is entered incorrectly too many times. Consider turning these on to protect information in the case of theft or loss.

*Policy Information:
UC Office of the President requires all campuses to implement the UC Minimum Security Standard. One of these requirements is that devices that store or access P2 or higher data are required to lock or go to screensaver (or be turned off) when left unattended for an extended period of time. A strong password must be required to start up or resume activity. 


Contact the ITS Support Center if you would like your computer configured to meet these requirements. If you have questions, contact the Support Center or your ITS Divisional Liaison.

Simple Security To-Do: Lock Your Computer Screen – ASK

Sometimes it is the simple things that make a difference. If you haven’t figured it out yet, your behavior and how you keep your office has an impact on the security of your employer. We’re not talking about a small impact either. Your interaction with your email, password hygiene, and how you handle sensitive data are critically important. Let’s not fool ourselves privacy is not going to become less of a concern as time goes on. The has decided to lead the world with their General Data Protection Regulation and it is only a matter of time before other governments follow suit.

Have you read your employer’s acceptable use policy recently?
You should. It’s likely you will find there are expectations for your behavior where technology is concerned. Even if you are working in an environment where these policies haven’t quite caught up to the technological reality we live in, you don’t want to the be the catalyst for a security incident.

Simple Security To-Do: Lock Your Computer Screen

Let’s look at a simple change you can make to start off on the right path.  Do you walk away from your unlocked computer to use the restroom when you’re at the office? How about when you’re working remotely, like at a customer site or in a restaurant? 5 years ago, no one would think twice about doing this. Things have changed though.

When you leave a logged in computer unlocked at the office, you give unauthorized individuals the opportunity to access data or perform activities they may not be authorized to see or use. Insider threats are very real and incident responders need to be able to identify a systems user based on the credentials they authenticated with. Leaving computers unlocked makes this much more difficult and sometimes impossible. Your computer may be configured to lock itself after 15 minutes and while it is a little inconvenient to log back in when you come back, once you have a little time to adjust, it will become second nature.

So instead of waiting for the computer to time-out or doing nothing, push the Windows Key + L every time you leave your computer. Locking your computer is as simple as pushing the Windows Key + L.

If you’re working remotely or in a public location you really should not leave any electronic devices (laptop, phone, tablet) unattended but in some cases, it may be necessary (this includes your hotel room and car). It is especially important you manually lock your computer in this situation. It could mean the difference between someone not only stealing your computer but also your company’s data.

Locking your computer really is the simplest of behavior changes and helps protect you and your employer from being involved in a security incident.

How Hackers Can Compromise Your Computer Monitor

Everyone knows your computer can be hacked, but did you know your monitor might also be used against you? Ang Cui from Red Balloon Security has figured out a way to hack into a popular Dell monitor and manipulate what you see on your screen. Using this type of attack, a user could easily be tricked into revealing personal, private information. Here’s how it works. Following is a transcript of the video.

Ang Cui: Basically, you can’t trust the thing that’s coming out of your computer, because the monitor is changing the content of the screen.

Hello, my name is Ang Cui. I am the founder and chief scientist of Red Balloon Security.

Let’s look at a typical embedded vulnerability and what it means.

Here we have a beautiful Dell (U2410) 24-inch monitor. And if you look at this website, it’s obviously a mock not- real website. What you probably have not thought about is that this monitor also has a computer inside the monitor itself that’s responsible for displaying pixels and selecting input. It’s generally called the on-screen display controller.

Now our research found that there is a way for an attacker to gain access to and cause arbitrary code execution inside the controller of the monitor itself. What if you can’t trust the output of your computer, because the monitor is actually changing the pixel values on the screen?

So that’s exactly what we did. If the attacker redirects you to a website that looks a lot like your banking website, you’re not going to be able to see that same SSL lock on your browser. So this is where the attacker would then compromise your monitor and put that SSL lock onto the screen.

We’ve made this SSL lock not move at all. It is possible to have this thing move with the browser, but for demonstration purposes, we’ve made it not follow the screen.

So your computer is not showing you that your connection is secure, but the monitor is overlaying the SSL lock onto it.

We can use the monitor itself to change what you see as in your bank account. So instead of having $100, we can make your monitor show that your bank account has a million dollars. There’s no way for the user to know, because we only interact with this computer through the monitor.

We estimate that there’s at least a billion monitors on the planet today that’s vulnerable to this type of attack.

Ang calls the hack “A Monitor Darkly.” The exploit is detailed on Red Balloon’s GitHub.

Monitor Darkly is featured in season 3 of “Mr. Robot.” 

Elliot Alderson: What were you doing by my computer? I saw you behind the monitor.

Ang’s team has informed Dell about the vulnerability. Dell recommends users update to a U2415 monitor. They say “security is a top concern and priority.”

What is a firewall? | Kaspersky Lab

Firewall acts as a local computer protection against viruses, worms, Trojans and hacker attacks.

A firewall is a software (security solution) or hardware (physical router) element of a computer network that monitors and filters network traffic passing through it in accordance with the specified rules.

Firewalls scan each “packet” of data (small chunks of a large whole, reduced in size for easy transmission) to make sure they are free of malicious elements.

There are several principles for handling incoming traffic.First, the firewall can display all requests for access to the computer from external networks and analyze the requesting service: whether it has a known domain name and Internet address.

Firewalls can also fully examine each packet of incoming data for the presence of lines of code that are in the black list.

Finally, firewalls can rate packets based on their similarity to other packets that were recently sent and received.

Packages that are within acceptable affinity levels are recognized as allowed.


The idea of ​​a firewall is borrowed from the concept of fire extinguishing: a firewall (firewall) is a barrier designed to prevent the spread of fire.

The purpose of the firewall is also to block everything that can “burn” the user’s computer.

Neither software developers nor security service providers can do without firewalls.

Windows operating systems come with a built-in firewall and it is generally recommended to leave it enabled.

But in your home network, it is recommended to use a hardware solution such as a router to filter network traffic.

Security software companies typically include firewalls in their anti-virus solutions.

In many cases, these are firewalls of a higher complexity than those included with the base operating system.

Standard firewall features include logging and reporting of attacks (successful or not), as well as notifications in the event of an unauthorized intrusion.


Potential disadvantages include slowing network traffic, especially if packets are fully analyzed on the user’s local computer.

In addition, some firewalls can accidentally block legitimate sites, but this can be fixed by adding them to the list of excluded sites on the service’s control panel.

    90,000 10 Ways to Speed ​​Up Your Windows 10 PC
    4. Disk Cleanup

    One of the built-in features of Windows 10 is Disk Cleanup. It allows you to get rid of unused temporary files that accumulate on your computer, including thumbnails of images, downloaded program files and temporary Internet files.

    Open the Windows menu and use the search bar to find Disk Cleanup. A list of program files to remove will open.Select the files you want to delete by checking the boxes next to their names. After that click on “Clean up system files”. Disk Cleanup calculates how much memory will be freed.

    Take time to remove other files or applications that are taking up RAM or disk space. Check your Downloads folder for old and unused files that you can delete.

    5. Removing old software

    PCs often come preinstalled with third-party software that you may not need.They are often referred to as “fat” software, can consume disk space due to their large size, and are often never used.

    You may have other programs installed but never used, which slows down your computer. To check which programs are installed, open menu

    • Control Panel> Programs> Programs and Features> Uninstall or change a program.
    • Right click on the program you no longer need and select Uninstall.
    6. Disable special effects

    Windows 10 comes with a lot of special effects that make the user interface look more pleasing. They are enabled by default in Windows and other features that are programmed to fade in and out of sight. Other special effects that slow down the speed of work are transparency and animation.

    Open the Windows menu, find the System menu, click the Advanced System Settings tab, then Advanced and select Performance Settings.Click the Visual Effects tab and click the Special Effects radio button. You will see a list of visual effects that can be turned off by unchecking the checkbox next to the name. Click “Apply” to confirm your changes.

    7. Disable transparency effects

    In addition to using system resources to display features such as animations, Windows 10 also uses transparency effects for certain features, such as the task menu. This seemingly light and simple effect is actually quite complex and requires more system resources than you think.

    To turn off transparency effects, open the Windows menu and type “color options” in the search bar to bring up the corresponding menu for Windows 10. Scroll down to the Transparency Effects button. Click the button to enable or disable these effects.

    8. Perform system maintenance

    Windows 10 has a built-in feature that performs standard system maintenance tasks. These include defragmenting your hard drive, scanning for updates, and checking for malware and viruses.

    System maintenance usually runs in the background when your computer is not in use, but you can manually start it if the system has a problem that you want to check.

    To do this, open Control Panel and select Security and Service Center. Click the arrow to expand the maintenance options and select Start Maintenance. You will be able to perform a preventive check of the system manually.

    9. RAM upgrade

    One of the radical ways to improve the speed and performance of your PC is to upgrade the RAM to increase the amount of memory on your system.Windows 10 requires at least 4GB of memory to run smoothly. If you are using your PC for intensive system loads such as gaming or multimedia creation, you will benefit from more memory.

    Upgrading your RAM can significantly increase the speed and performance of your PC. To find out what type of RAM your PC needs, open Task Manager (Ctrl + Alt + Delete) and click on Performance. You will see how many memory slots are available as well as the type of RAM such as DDR4.

    10. Disk upgrade

    Upgrading your drive can dramatically improve the speed and performance of your PC. Most PCs come with spinning hard disk drives (HDDs), but switching to solid state drives (SSDs) will make your system much more powerful.

    SSDs are generally more expensive than hard drives, but making system boot faster, loading programs faster, and improving overall system performance can be worth the money.

    SSDs come in a variety of form factors or sizes, depending on the system requirements of your PC.For desktops and laptops, 2.5-inch and M.2 form factors are available. Make sure you buy a suitable solid state drive that is compatible with your system. You can also transfer all your files and documents from your hard drive to your new SSD, so you don’t have to worry about losing your PC’s contents. Authenticator – Blizzard Support
