Architecture and other features
Windows 11 is only available for the x86-64 and ARM64 CPU architectures, as Microsoft is no longer offering a Windows build for IA-32 x86 and ARMv7 systems.[1] Additionally, NTVDM and the 16-bit Windows on Windows subsystems, which allowed 32-bit versions of Windows to directly run 16-bit DOS and Windows programs, are no longer included with Windows 11.
User-mode scheduling (UMS), available on x64 versions Windows 7 and later, was a lightweight mechanism allowing applications to schedule their own threads, without involvement from the system scheduler. This feature is not included with Windows 11.[14]
Themes
The Windows 10 and Flowers theme has been removed in Windows 11. Also upgrading to Windows 11 of Theme1 and Theme2 Wallpaper Folder is empty.
