Windows 11 has come a long way from its infant stage. Today it is incredibly good and stable operating system that also looks good and modern. Unfortunately, fancy animations and good graphics come with a price, in this case, slower performance on some little older and weaker computers.

Animations itself which include also fading effects can sometimes feel slugging and laggy and have a general overall feeling of delay. For a more old-school instant experience, you can turn off animations.

In order to turn animations inside Windows 11 follow this simple guide:

First thing is to open Settings by pressing Windows + i key combination or you could open Start and in the search box type in Settings and then click on its icon.

Once inside settings on the left side find Accessibility and click on it to select it. Once it is selected on the right side choose Visual effects. Inside the visual effects section click on the switch next to Animation effects to OFF. You can also turn off transparency effects in this section if you wish if you have an older GPU in order to speed it up a little.

That is all you need to do, settings will be automatically saved and all animations will be turned off for a quicker and more responsive feeling when working inside W11

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.

A lot of users complain about low storage space each time a Windows Feature update is released as well as to complain about not being able to download the updates, slow update experience, and many other complaints. The main issue is that many users do not have enough storage space available on their PCs. And now to make sure that none of the updates gets stuck because of low storage space, Microsoft presented the Reserved Storage feature which comes preinstalled with v1903 or those where v1903 was clean installed. This guide will be showing you how you can enable or disable the Reserved Storage in your Windows 10 computer. As you know, the Windows Update process should have enough space so that it can download, extract and apply the update on the computer. Usually, the size of the Reserved Storage is around 7GB which gives enough space for the update, temporary files, system caches, apps, and many more. And according to Microsoft, the size of the Reserved Storage space will vary from time to time and will depend on how you use your computer.

Explanation

The Reserved Storage space feature is enabled by default on devices that come preinstalled with the May 2019 update or after performing a clean installation of the Windows 10 OS. To check if your computer has this feature, you need to go to Settings > System > Storage and from there click on the “Show more categories” link and then click on the “System & reserved” option. However, if you can’t find the Reserved Storage from the list, then it’s probably because your computer has limited space on the hard disk or it is not a fresh or new install. On the other hand, if you have this feature but have no use for it and want to disable it instead, then read on as this post will also show you how it’s done.

Solution

Keep in mind that when you disable the Reserved Storage feature, chances are, you might be unable to enable it back so you need to make sure that it’s really what you want to do before you disable it permanently. So if you really want to disable Reserved Storage, you can do so using the Registry Editor. Before you proceed, you have to create a System Restore point first and then carry out the following steps.

• Tap the Win + R keys to launch the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionReserveManager
• From there, double click on the DWORD named “ShippedWithReserves” and set its value to “1”.
• Once you’re done, restart your computer and see if the Reserved Storage feature is now gone.

On the other hand, if you want to reduce the Reserved Storage space, there are two ways you can do that. First, you can go to Settings > Apps > Apps & features > Manage optional features and from there, uninstall the optional features that you do not use. The second one is you have to go to Settings > Time & Language > Language and then uninstall the languages and their add-on which you don’t use. Note: The Reserved Storage feature is also used by system processes and apps to create temporary files and once the Reserved Storage space fills up, Windows 10 will delete them automatically. It is undeniable a useful feature so disabling it is not recommended but if you are running on low storage space and don’t have much choice, then you may disable it at your own risk.

Error code 0Xc004F074 - What is it?

Did you previously use Windows 7 or 8 but decided to run with the latest Windows 0S, Windows 10? An early error message encountered was activation error code 0Xc004F074. Error code 0Xc004F074 is manifested when the user fails to activate Windows directly after the installation of Windows 10. This occurs if the previous operating system on your computer was Key Management Service (KMS) activated.

The KMT provides a more seamless operation when users are activating volume license editions of Microsoft Windows and Office. This process tends to be clear to end-users of the system.

Symptoms of error code 0Xc004F074 include:

• Windows is unable to reach your company’s activation service.
• The Key Management Service is unavailable.

Solution

Error Causes

Various factors might incite error code 0Xc004F074. A primary cause is a discrepancy or difference between the KMS client and the KMS host machine. The host computer could possibly be operating a Windows Server 2003 or Windows Server 2008, while the client runs on OS Windows 7 or Windows Server 2008 R2. To supplement, the computer’s time might be a contributing factor. The time on the host machine and client might show a difference (Usually the host time exceeds 4 hours).

Further Information and Manual Repair

To rectify error code 0Xc004F074, users are advised to try various methods. These methods include:

1. Method 1: Update Your KMS Host 9 (Windows Server 2003)

Are you running later versions of Windows Server? Use an update that fixes or installs KMS on your computer. The update is available on Microsoft’s website. Keep clearly in mind that the update is only for Windows Server 2013 Service Pack 1 and later versions of Windows Server 2003.

2. Method 2: Update Your KMS Host 9 (Windows Server 2008)

This step is similar to the aforementioned. However, it applies to Windows Vista and Windows Server 2008. This ensures the service is extended to Windows 7 and Windows Server 2008 R2.

3. Method 3: Update the Time

It was previously mentioned that the time reflected on the KMS host and client might cause error code 0Xc004F074 to manifest. A simple fix to adhere to is to always ensure that the time between both is updated. To Resync the time on the client, execute the following command.

w32tm /resync

4. Method 4: Uninstall the Existing KMS

For this method to be successfully deployed, you’ll need to have in your possession an activation key or KMSpico Key. As you cannot apply the new key with the existing one, remove or uninstall the initial key. To perform this step, open the command prompt. This should be done while the computer is in admin mode. Then, run the command

(slmgr.vbs /dlv)

It should be executed without the brackets and before you have removed the existing key.

After executing the command, you’ll encounter the description:

Windows(R) Operating System, VOLUME_KMS_WS12_R2 channel

Move along with the process by applying the slmgr.vbs /upk to uninstall the existing KMS key.

After the old key is uninstalled, you’re ready to apply the following:

slmgr.vbs /ipk <NewKMSProductKey>

To check if things are in place and complete the process, follow the steps below: PC Settings >Update and Security > Activation

5. Method 5: Download an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 8 and other related issues when they do arise, download and install a powerful automated tool.
