Store- major stores like Spotify, Feedback hub, Microsoft Store and many more start to crash.

Windows Subsystem for Linux 2- users were now able to use the Windows Hello without using the password. Not only Windows Hello was used without a password but Windows Help Pin can also be used in Safe mode too.

Win32k- basically it was malware that threatened the operating system in many ways. The malware was able to disturb the user experience with issues like unstable connection, browser redirects, poor PC performance, browser, and home screen being bombarded with pop-ups and other issues like screen freezing.

Group policy security issues- there was an issue with the Group Policy services where different important files were being deleted. All the files in “%systemroot%\system32” order were deleted whenever the user deletes the cached profiles.

Third part drivers- another issue was experienced in the installation of third-party drivers. Such situations cause the “0x5A (CRITICAL_SERVICE_FAILED)” error to appear.

Battery draining- laptop users (mostly HP laptop users) were facing the battery draining phase. It was due to the poor integration between OS update and the laptops BIOS setting.

IME- App like Microsoft Word, Access, or Excel stops responding for Chinese and Japanese in Microsoft Input Method Editor (IME).

Mouse- input device like mouse were stuck and had no response too.

Other issues like cloud download option to reset windows, issues with creating null port using the user interface, and Windows subsystem for Linux to crash “Element not found” error was also fixed.
