Windows 11 2026 Update Brings 1000Hz Support and SAC Toggle, With Offline Installer Links
Microsoft released Windows 11 KB5079391 (March 2026 optional preview) as Build 26200.8116 for 25H2 and 26100.8116 for 24H2. It adds 1000 Hz refresh-rate support for compatible monitors, lets you enable/disable Smart App Control without reinstalling Windows, and provides direct .msu offline installer links. The update also includes File Explorer and display fixes, with changes expected to roll into April Patch Tuesday if you don’t install the optional update now. Auto-updates can install it if you have the “Get the latest updates as soon as they’re available” toggle on.
