Important! As of January 10, 2023, Microsoft will no longer support Windows 8.1. This means PCs running Windows 8.1 will still function, but will no longer get software or security updates.

The December 13, 2022 security update will be the last update available for this version. After that date, devices running this version will no longer receive monthly security and quality updates.
End of support for Windows 8.1 systems also means end of support for Microsoft EDGE there... the last 8.1-compatible version of EDGE being 109.
