Although the focus of Microsoft's work has shifted to Windows 11, it has not given up on improving support for Windows 10. Today, it released a major patch KB5009596, which includes new features, detailed optimizations, and bug fixes.

First, it brings a new feature called "Sync your Settings", which can back up and save apps installed with a Microsoft account, and restore them intact after upgrading to Windows 11, even if you change devices.

At the same time, the error message 0x80090011 that will appear when querying TPM information through the Get-TPM PowerShell command during the Windows 11 upgrade has also been fixed.

If you are still using the IE browser, a prompt will appear after updating this patch, telling the user that the IE browser is about to be retired and can no longer be used, and it is recommended to upgrade to Edge.

Several other bug fixes are also very useful, especially a fatal bug that can easily lead to system crashes. The error message is IRQL_NOT_LESS_OR_EQUAL. In addition, WSL2 Linux subsystem stops working after enabling fast boot, USB printer error, and Edge surround sound playback error, vpnike.dll/rasmans.dll is locked due to performance problems.

The KB5009596 patch can now be updated online through Windows Update, or you can download the update manually, supporting Windows 11 20H2, 21H1, and 21H2 versions.
