9 Known Issues With Windows 11 and How to Fix Them

Microsoft is aware of eight known issues in the initial release of Windows 11, and some of these issues have been fixed. In this guide, we will help you fix some common Windows 11 Errors.

Windows 11 is officially released, and users are already facing various issues that prevent them from adequately upgrading the Windows 10 operating system to the latest version of Windows 11.

As with any significant feature update or new version of Windows, there are inevitable incompatibilities with software and hardware that cause crashes or other instability.

Below, we’ve listed eight known issues regarding Windows 11 and published possible solutions to some of the problems.

Error 1: You still see Windows 10 taskbar on Windows 11

After upgrading to Windows 11, some users report that they are still using the old Windows 10 taskbar rather than the panel designed for the new operating system.

Some users are frustrated by this as they prefer to use the new panel, while others are happy as the latest Windows 11 taskbar lacks some of the features of the Windows 10 taskbar.

Missing features include the ability to drag and turn apps or shortcuts to the taskbar; the ability to move the taskbar up and on the sides of the screen; the Context menu to ungroup program windows, caused by right-clicking.

Although Microsoft has not publicly acknowledged the bug in which Windows 11 uses the taskbar from Windows 10, the company is studying this problem.

So far, users have provided various methods that you can use to try to restore the Windows 11 taskbar.

Method 1: Uninstall the latest Windows 11 update, restart your computer and reinstall all available updates. Since Windows 11 is the latest version, most users will not have updates installed, and they can move on to the following method.

Method 2: Open a PowerShell command prompt as administrator and run the following command:

Get-appxpackage -all *shellexperience* -packagetype bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + "\appxmetadata\appxbundlemanifest.xml")}

This PowerShell command was used to solve problems with the Start menu in Windows 10 and should be suitable to solve the problem with the taskbar in Windows 11.

Method 3: In extreme cases, you can create a new user profile, and the Windows 11 taskbar should be restored in this way. However, this method will require you to copy all your data and possibly reinstall the apps in the new profile.

Error 2: Windows 11 Start menu won’t open

Users report that they are faced with a problem with the Start menu: it no longer works after upgrading to Windows 11. The Start menu just doesn’t open or freezes.

As the problem with the taskbar above, Microsoft hasn’t publicly acknowledged this bug or provided a fix, but the company is investigating the issue.

Windows 11 users could fix this problem using the methods described above, which applies to solving problems with the taskbar.

Error 3: Up to 15% reduction in AMD processor performance

AMD reported that users could experience a CPU performance degradation of up to 5% when using specific applications, and in some games, the performance degradation is as high as 15%.

Problems with the performance degradation of AMD processors are caused by increased latency of the L3 cache and the fact that UEFI CPPC2 may not schedule threads on the fastest processor core as a priority.

AMD said it is working with Microsoft to fix the CPU performance degradation and hopes the fix will be available this month.

Error 4: Invalid error “Windows 11 can’t start on this PC”

Some users have been unable to upgrade Windows 10 to Windows 11, even though their PCs meet the Windows 11 system requirements. WindowsUpdate displays the message”This PC doesn’t currently meet all the system requirements for Windows 11, “even if their hardware is compatible.

What’s particularly frustrating is that users’ computers are being tested for PC health, their hardware is compatible and should work fine with Windows 11.

Ultimately, there is no way to work around this error without using a Windows 11 hardware bypass scenario designed to allow a new operating system to be installed on incompatible hardware.

“We are aware of this issue and are currently working to fix it,” a Microsoft support agent told WindowsLatest.

Error 5: RAM leak in Windows Explorer 11

Since the release of Windows 11 preview builds, a memory leak in File Explorer has caused the app to use too much system memory.

The leak caused File Explorer to use 1 GB of memory after opening multiple folders for some users. What’s worse is that when you close Explorer, memory is not freed up and remains unusable by the system until Windows 11 restarts.

Microsoft has fixed memory leak issues in the Windows 11 Build 22454 (Dev) preview build, but it’s unknown when the patch will make it to the update channel of the final release.

“We included changes to build 22454 to fix several issues that caused memory leaks when using File Explorer,” Microsoft commented in the Feedback Hub report on the memory leak.

Error 6: Windows 11 compatibility issue with Oracle VirtualBox

If Oracle VirtualBox is installed on a Windows 11 device with Hyper-V enabled, a compatibility issue may cause virtual machines not to start. Also read: How to Enable Virtualization in Windows 11? Easy Guide

“Microsoft and Oracle have discovered a compatibility issue between VirtualBox and Windows 11 when Hyper-V or Windows Hypervisor is installed. You may not be able to start the virtual machines and you will receive an error message,” Microsoft said in a message.

Microsoft has set a compatibility ban to prevent these problems that will prevent users from upgrading to Windows 11 unless Hyper-V, Windows Hypervisor, or VirtualBox are removed from the device.

Oracle is working to resolve this issue and hopes a new compatible version will be available this month. However, those who try to install Windows 11 before this hotfix becomes available may see the following error:

«VirtualBox. Your PC requires the latest version of this app. Click Learn More to learn how to update the app.”

Microsoft also advises users not to force an update using bootable media or the Windows 11 Installation Assistant to bypass this compatibility limitation.

Error 7: Loss of network data when using Intel Killer and Dell SmartByte applications

Microsoft has detected compatibility issues with Intel Killer and Dell SmartByte.

Both Intel Killer and Dell SmartByte are applications that claim to optimize and accelerate your browsing experience by prioritizing network connections based on the type of activity.

Microsoft has discovered that these apps have Windows 11 compatibility issues that cause User Datagram Protocol (UDP) packets to be discarded when communicating with remote devices.

“Compatibility issues have been found between some of Intel’s ‘Killer’ and ‘SmartByte’ network software.

“This creates performance issues and other issues for UDP-based protocols. For example, some websites may load slower than others on affected devices, with streaming video at certain resolutions slower. VPN solutions that use the UDP protocol may also be slower.” Devices with vulnerable software can discard User Datagram Protocol (UDP) packets under certain conditions,” Microsoft explains in a list of known issues affecting Windows 11.

Microsoft says they are working on a fix and plan to release it as part of Tuesday patches next week, Oct. 12.

Error 8: Compatibility issues with Coc Coc browser

Microsoft has discovered a compatibility issue with the Coc Coc browser that prevents the browser from opening and can cause other problems and errors.

To protect users from update issues, Microsoft has set a lock that prevents this browser from upgrading to Windows 11.

Microsoft says they are investigating the issues and providing additional information when it becomes available.

Error 9: Problem connecting Brother printers via USB

Brother is investigating the compatibility conflict between its laser and inkjet printers in Microsoft’s new OS. The company has created separate support pages for both types of printers, which report:

When researching the problem, Brother analyzes several of its printing apps, including Presto! PageManager, Presto! ImageFolio, PaperPort, and BookScan & WhiteBoard Suite to identify potential Windows 11 compatibility issues.

Brother users may also receive a “Cannot print to USB printer” error message when using the USB Connection Repair Tool. Other programs may also display error messages after upgrading to Windows 11 when you try to print or link to an installed printer, namely:

The Deskmodder portal reports that the problem can be fixed by disabling the USB connection, removing the printer drivers, removing the printer through Device Manager, restarting Windows 11, and then reinstalling the drivers and connecting the printer via USB.

Microsoft has not yet officially acknowledged the problem.
