Some built-in tools still treat Windows 11 as a separate version from Windows 10.
Some built-in tools still treat Windows 11 as a separate version from Windows 10.
You're having trouble updating your user settings because the built-in tool isn't identifying your Windows version correctly. The Microsoft tool assumes you're using Windows 10, but your system is running Windows 11, which may not be supported. This issue could also stem from Microsoft's decision to stop backing Windows 10 officially.
You would encounter the same issue on Windows 10 Home. The system isn't verifying the Windows version (10.0.XXXXX), but rather the edition or SKU (Home, Pro, Enterprise). Microsoft typically maintains management features starting from Pro. To manage user groups, you can utilize PowerShell.
It wouldn't be unexpected to find similar mistakes across the OS, given that Windows 10 was marketed as the final version at launch.
Express your dissatisfaction clearly since you can't even operate the tool. If you dislike version 11, avoid using it.
