Today, Microsoft released the preview version of Windows 11 Build 22000.282 (KB5006746), which was launched for Beta and Release Preview channel testers of the Insider program, and finally fixed the CPU performance degradation problem that AMD had previously admitted.
Windows 11 is being rolled out gradually, and many users have already installed a new operating system, but some users have noticed a significant drop in performance. According to media reports and AMD’s statement, a bug in Windows 11 may significantly reduce the performance of compatible AMD processors.
In fact, users may also encounter problems with regular applications when running Windows 10 on AMD hardware. If you have installed Windows 11 on an AMD CPU and noticed performance issues or application/game issues, Microsoft is now rolling out a fix through Windows Update.
Windows 11 Build 22000.282 is now available to testers of the Insider program. It finally solves the compatibility problem of the L3 cache, which affects the performance of some applications. In fact, AMD claims that if users install Windows 11, L3 cache latency may increase nearly three times.
Therefore, the performance of the application is affected by 3-5%, and the performance of some games drops as much as 15%, especially games used for e-sports. Obviously, this bug was serious enough, and Microsoft immediately implemented repair measures. After installing Windows 11 Build 22000.282, if you load an application or game on an AMD CPU, in theory, Windows will not reduce the performance of the application.
However, this update is still being tested, and users of the official version of Windows 11 may not get this fix until the end of this month, and it is an optional update patch. This repair patch will also appear in the “Tuesday Patch” in November 2021. Until then, you can downgrade to Windows 10 and stop playing games for now or simply wait for the optional update to be released later in October.
In addition to performance improvements, Microsoft has also fixed an issue where the new Start menu cannot appear on Windows 11 when upgrading from Windows 10. It also fixes a resource competition bug, which may cause a blue screen or black screen of death when Windows starts. In addition, Microsoft also fixed the bug that used non-ASCII characters in the registry to cause the PC to the blue screen of death.
The following Windows 11 Build 22000.282 update and repair content
- Fixed the L3 cache issue, which may affect the performance of some applications on devices with AMD Ryzen processors after upgrading to Windows 11 (the initial official version).
- Fixed a problem encountered by a small number of users, which would prevent the “Start” menu from working after upgrading to Windows 11 (the initial official version) and prevent you from seeing the updated taskbar design.
- Fixed a resource competition issue that occurred during the initial startup period. This condition may cause a stop error.
- Fixed a regression that may cause stop error 0x38 on some device configurations that use non-ASCII text in the registry.
- Fixed the interrupt handling problem of some processors, which may cause the device to stop responding.
- Fixed an issue that caused PowerShell to create an unlimited number of subdirectories. This problem occurs when you use the PowerShell Move-Item command to move a directory to one of its subdirectories. As a result, the convolution is full and the system stops responding.
- Fixed an issue that caused the Server Manager application to disappear after deleting the Hyper-V function using Server Manager. This problem occurs when you use the Remote Server Management Tool (RSAT) to install Server Manager on the Windows 11 (initial official version) client.
- Fixed a thread issue that could cause the Windows Remote Management (WinRM) service to stop working under high load.
- Fixed an issue that caused the Windows Management Instrumentation (WMI) provider host process to stop working. This is because an unhandled access violation occurred when using the desired state configuration (DSC).
- Fixed an issue that caused the device to stop responding when you forcibly shut down the device while updating the group policy.
- Fixed an issue that caused file migration between distributed file system (DFS) paths stored on different volumes to fail. This problem occurs when you use the PowerShell script of the Move-Item command to implement the migration.
- Fixed an issue that prevented writing to the WMI repository after a low memory condition occurred.
- Fixed a hard-coded font issue in the PowerShell shortcut file, which deformed Japanese, Chinese, and Korean fonts. This update fixes this issue for all newly created users on the device. Existing users can use the C:\Users\Default\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Windows PowerShell\Windows PowerShell.lnk file to open PowerShell to solve this problem. In addition, existing users can create a shortcut to the file on the desktop and use the shortcut to open PowerShell.
- Fixed the problem of parsing the time format when excluding milliseconds from the event.
- Fixed an issue where some Enhanced Metafile Format (EMF) files were rendered incorrectly. This problem occurs if you use third-party applications ExtCreatePen () and ExtCreateFontIndirect () to build EMF files.
- Provides an option for administrators to reset the zoom ratio of the HTML dialog box in Microsoft Edge Internet Explorer mode to the default value.
- Fixed an issue where the corporate mode website list was redirected from Internet Explorer 11 to Microsoft Edge. In some cases, redirects open a website in multiple tabs in Microsoft Edge.
- Fixed an issue that caused Internet Explorer to stop working when you entered certain characters in the Input Method Editor (IME).
- Fixed a problem with PropertyGet in JScript9.dll.
- Fixed the memory leak problem that occurred when using nested classes in VBScript.
- Fixed the problem that the NumLock state could not be maintained after quick start and restart.
- Fixed the problem of moving some application windows. If there is a file explorer window on the screen, moving these application windows may be unusually slow.
- Fixed an issue that prevented the Mail app from accepting keyboard input in the address and subject boxes intermittently.
- Fixed an issue with the user interface of renaming files using the folder view in File Explorer. UI failed to properly handle internal syndication using the new Japanese IME.
- Fixed an issue where a black screen would appear intermittently when signing on the credential page when using App-V.
- Fixed an issue with the Internet print server, which failed to package the modified printer properties correctly before sending the package to the client.
- The group policy settings for the following registry values have been implemented (see KB5005010 for more information ).
