Windows 8.1 is an operating system by Microsoft. It is a free upgrade for existing Windows 8 users. It replaced Windows 8 and was succeeded by Windows 10 on 29 July 2015. This is the first version of 64-bit Windows to drop support for processors without the CMPXCHG16b, PrefetchW and LAHF/SAHF instructions, as running on these processors will result in a bugcheck with error code 0x5D.
Although the operating system was marketed by Microsoft as an update for Windows 8, Microsoft's traditional support policy treats Windows 8.1 as a service pack.[1]
As of June 2022, it runs on 2.83% of desktop and laptop computers.[2]
It is the last release of Windows to have support for Windows Media Center as Microsoft discontinued support for the application with the release of Windows 10. It is also the last release of Windows to have the ability to create MS-DOS 8.00 startup disks, and thus to include MS-DOS in any form and to ship with a DVD release, since physical retail copies of Windows 10 and later ship with an USB mass storage device.

and set it to 1, then restart explorer.exe.Windows 8.1 is officially compatible with Intel processors up to Skylake (6th Generation). On Kaby Lake (7th Generation) up to Coffee Lake (8th/9th Generation), 8.1 is not supported due to a lack of Windows Update and Intel Graphics, however, hacks have been made to get both working. For Ice Lake (10th Generation) up to Alder Lake (12th Generation), no known hacks have appeared for Intel Graphics, but the chipset drivers for Ice Lake, Tiger Lake (11th Generation), and Alder Lake have been confirmed to install without any issues.
