Windows 11

Windows 11 is a series of Microsoft Windows operating systems that succeeded the Windows 10 series in 2021. It was originally announced in June 2021 and the initial version was released on 5 October 2021.

This is the first version of Microsoft Windows to not support the IA-32 architecture (32-bit x86 systems) as the operating system now requires an x86-64 processor with CMPXCHG16b, PrefetchW and LAHF/SAHF instructions. It is also the first version of Microsoft Windows to not include NTVDM meaning that 16-bit apps are unsupported and thus, can't run in Windows 11.
