Finally upgraded to Microsoft’s newest OS, but the performance is a bit sluggish? Here are a few useful tips you may not have thought about that could significantly transform your experience!

How to speed up Windows 11?

1. Disable startup programs

There are many programs that launch right on startup that really aren’t essential. This, in turn, causes your PC to launch and run more slowly.

To check which programs are enabled on startup, go into the Task Manager and select the Startup tab. Find every program that doesn’t need to launch immediately, right-click on it and press ‘Disable’.

This will not shut down the program in that instant. It’ll just prevent it from running automatically as you turn on your PC. You can always launch it manually when you need it.

2. Expand your memory and storage

If you want your PC to run super smoothly, you need to have enough memory to support that. This is especially significant for those of you who love to multitask. Upgrading your RAM gives your PC more space to store the temporary data it needs to complete processing tasks. In other words, processing takes a lot less time.

Your long-term storage is equally important. Hopefully at this point you’re already using SSD over HDD, since this type of storage offers a faster boot time.

In any case, we recommend expanding your storage capacity. The more files and data you store, the more there is to load, significantly influencing your PC’s speed. Larger storage capacity means new data and essential updates can be stored comfortably, preventing any strain on your PC’s performance.

3. Clean up disk space

If you aren’t willing to upgrade your storage just yet, the least you can do is clean up your storage right now. 

Aside from manually deleting stuff you no longer need, you can also get rid of temporary files that clutter up your storage and eat up performance for no reason. To get to them, click Windows + X and select ‘Run’ (or just type it in the search bar).

A small window will pop up, where you need to type %temp%. This will take you to a whole folder full of all the temporary files you can remove without thinking twice. 

For those who upgraded from Windows 10, there’s a neat trick to get rid of potential leftover files you don’t need on your brand new iteration. Only do this if you’re 100% sticking with Windows 11, though. Go to System > Storage > Temporary files. Make sure to only leave ‘Previous Windows Installation’ and ‘Windows Update Clean-up’ checked and click on ‘Remove files’.

Lastly, make use of Windows 11’s fantastic Storage Sense feature. Turning it on will enable your PC to constantly watch out for junk or unused files to optimize your PC’s performance to the maximum.

4. Install pending updates

This one should go without saying, but pending updates can be detrimental to your Windows 11 performance. The longer you leave them untouched, the more bugs the outdated programs and patches can cause. So, make sure to regularly check for updates and install them as soon as they’re available.

5. Disable visual effects

As cool as visual effects, animations, shadows and transparency are, they can also put quite a toll on your computer’s speed. On a newer setup this generally shouldn’t be a problem, but if you do notice a drop in performance, definitely consider turning off some of these settings.

To do this you can go to the Control Panel, System Properties and click the ‘Advanced’ tab. In the Performance section, choose Settings. If you’d like a quicker way to get to the dialog (Performance Options) with Visual Effects, you can also type sysdm.cpl in the search bar.

Once there, you can either have your PC choose what’s best, choose the best appearance or the best performance. The other option is to manually toggle the effects off and on. The biggest obstacles to speed are taskbar animations, window shadows, control/element animations and animations upon minimizing/maximizing.

In the same vein, you should go to Settings > Personalization > Colors and disable Transparency, to prevent your computer from doing overtime just to hit the aesthetic appeal.

6. Get rid of bloatware

Bloatware is one of the biggest culprits of slow computer speed. 

Pre-installed software that’s pretty much useless but takes up valuable system resources has been around since day one. No matter which device or platform you’re talking about. Luckily, a lot of it is removable, making it easy to lighten the load on your device.

To boost your Windows 11 computer, go to Settings > Apps > Installed apps. You’ll probably see a bunch of apps you don’t want or need. Click on the three dots next to each one you want to remove and press ‘Uninstall’. 

Aside from helping optimize performance, removing bloatware has another great benefit. Unfortunately, often this pre-installed software is quite vulnerable, exposing you to great risk of cyberattacks. So, removing it definitely improves your device’s security and gives you at least some peace of mind.

Summary

These are a few of our fastest tips for boosting performance. There are other, more complex and time-consuming ways, of course. If you’ve tried these quick ones and still need advice on how to improve your PC’s speed, feel free to reach out!

If you aren’t able to pull up any website and instead got the ERR QUIC PROTOCOL ERROR error message in Google Chrome then read on as this post will help you resolve the problem. When you encounter such an error in Chrome, you will see the following error message:

“This site can’t be reached, The webpage at [website URL] might be temporarily down or it may have moved permanently to a new web address, ERR_QUIC_PROTOCOL_ERROR”

This kind of error message pops up when the URL is down. However, if you are certain that the site is not down and you’re still seeing this error message, then troubleshoot further using the suggestions given below.

Option 1 – Try to disable the QUIC Protocol

QUIC is an experimental transport layer network protocol that is present in Google Chrome in order to establish a connection between two endpoints over UDP. So if there is any problem on the development side, you will most likely encounter ERR_QUIC_PROTOCOL_ERROR on your Google Chrome browser when you try to open any website. Thus, you have to disable the QUIC protocol in order to resolve the error. How? Simply follow the steps below.

• Open your Google Chrome browser.
• Now type in “chrome://flags/” in the address bar and hit Enter.
• After that, look for the Experimental QUIC protocol which should be set by default.
• Then expand the drop-down menu and select Disable.
• Restart Google Chrome and see if the error is fixed or not.

Option 2 – Disable VPN

As mentioned, if you are using VPN, this could be the reason why you’re getting the Windows Update error 0x800F0922 so the most obvious thing to do is for you to turn off the VPN and try to run the Windows Update once more. And if you use a VPN software that works using their software, you can just completely exit or log-off from its account. On the other hand, if you are using a built-in Windows 10 VPN, you can simply turn it off or delete all the settings you have created there. Although it’s understandable that you might have to use a VPN connection to connect to the work network, you really have to disable it at least until the Windows Update is no longer stuck in the error 0x800F0922. It would be best if you do this when you are not working.

Option 3 – Disable the Proxy server

You can also try to disable the Proxy server to fix the ERR_QUIC_PROTOCOL_ERROR in Chrome. Refer to these steps to do so:

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

If you got an error code of 0x80072EE2 while trying to download a Windows 10 update then it could be that something is blocking the Windows Update service on your Windows 10 PC and is preventing it from connecting to the Microsoft server. In addition, the error code 0x80072EE2 also indicates “ERROR_INTERNET_TIMEOUT” and together with this message, you might also see a message as Windows Update encountered an unknown error or you might also find it hard to search for new updates. So in this post, you will be guided on how you can fix the Windows Update error code 0x80072EE2. Make sure to follow the steps below carefully.

Option 1 – Restart your computer and try installing the Updates again

And so after you restart your computer, check for updates once again and see if you’re still getting the error or not.

Option 2 – Run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like error code 0x80072EE2. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 3 – Try to disable your antivirus program

Disabling the antivirus program or any security software installed in your computer is always a good idea you can try when the Windows Update process does not go smoothly. So before you try updating your computer again, make sure to disable the antivirus or security program and once the Windows Update is done, don’t forget to enable the antivirus program back again.

Option 4 – Try to restart the Background Intelligent Transfer Service

The Background Intelligent Transfer Service or BITS is a part of the Windows Update service and is the one that manages the background download of Windows Update, as well as scans for new updates and so on.

• Next, type “services.msc” in the field and hit Enter to open Windows Services.
• From the list of Services, look for the Background Intelligent Transfer Service and double-click on it to open Properties.
• After that, you need to set the Startup type to “Automatic (Delayed Start) and click on Apply.
• Now click the Stop button to stop BITS and then click the Start button to restart the service.
• Click OK to save the changes made and then restart your PC.

Option 5 – Try installing the updates in a Clean Boot State

It could be that some third-party application is the one that’s causing the problem so it’s best if you put your computer in a Clean Boot state. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After that, try to install the Windows app again.

Note: If you are able to install the app without any trouble at all then it means that the error is caused by some third-party application on your computer. You need to look for the culprit and uninstall it once you found it.

Option 6 – Run Microsoft’s online troubleshooter

Running Microsoft’s online troubleshooter might also help you fix the Windows update error code 0x80072EE2. This online troubleshooter is known to help in fixing Windows Update errors, it scans your computer for issues that might be causing the problem and then fixes them automatically.

What is Error Code 0xC004C003?

Error code 0xC004C003 has to do with activating Windows 10 after a clean install. This problem has been a frequent nuisance to users trying to update from Windows 7 or 8.1 following the invite path they got from Microsoft.

Solution

Error Causes

There are several problems that may have caused error code 0xC004C003. The most common of them are:

• The product key entered was invalid, and cannot be used to activate the new OS.
• The user followed the proper installation procedure, but the Windows update servers were too busy to handle the activation at that moment.
• The free upgrade invitation was followed but after the reinstallation, the copy of Windows 10 was still not activated.
• The user tried to perform a full clean install of Windows 10 instead of upgrading from Windows to Windows 10

Further Information and Manual Repair

A lot of solving error code 0xC004C003 has to do with the method in which the user has tried to update the system. If one decided to try and update the program before being invited to do so by the update manager, he must wait. Unfortunately, if one chooses to do it on his own and download a clean install, he was never given a product code to authenticate the process. There are two options to address error code 0xC004C003 — either restore to the previous Windows Operating System or call Microsoft (or visit their Website) and purchase a product key. The Windows update servers are very busy. There are lots of Microsoft users around the world, and the servers are doing their best to get to each and every one of the users as fast as possible, but they can only move at a certain speed. Your best bet is to sit back and wait a while. But what if you were invited, and properly downloaded Windows 10, then decided to do a clean install? It is advised that one do not try to enter Windows 7 or 8.1 serial code as this will not work. However, unlike the problem above, these users will NOT need to purchase a product key. According to Microsoft Support Staff, the installation servers are also very jammed because of the high numbers of installations going on right now. No matter what posts you may read, the key IS genuine, and it is NOT blocked, broken, or invalid. To check if Windows has been properly activated, open the Command Window. Make sure you are logged into an administrator profile; otherwise this check will not work. Type in “slmgr.vbs/ato” and click Enter and then wait. While waiting, the command will check on the status of the activation. Windows Script Host will open and show whether or not it is activated. A lot of users have reported that the activation did not work for the first few times. However they later reported after some more attempts, no issue was found in the way the operating system updated and that the activation process went smoothly. This is most likely due to the overload on the Windows Update servers, so bear with Microsoft. Users have reported that when trying to correct error code 0xC004C003, they have followed the upgrade path and then been told by Microsoft that the key was invalid and they had to purchase a new one. If the upgrade path provided by Windows 7 and Windows 8.1 is correctly followed then there is nothing to worry about Just wait a while and try it again. If there are prolonged issues, speak with a technician by visiting the Microsoft website and contacting the help center by calling the number provided. Give them all relevant information and they will be sure to help accordingly. The best solution to fix error code 0xC004C003 is to wait. In essence, the user will be waiting to reenter the same product key. According to Microsoft, and many user posts found online, it is recommended to wait a while and then try to activate again. This seemed to be an answer to most users' problems, and seem to work just fine. If the problem persists, take it to a windows repair technician to have it sorted out. If that does not work, use a powerful automated tool to fix the problem.
