About this tag
The optional preview update tag covers Microsoft's non-security cumulative updates for Windows 11, typically released in the second half of each month. These updates allow users and IT administrators to test new features and fixes before they become mandatory on Patch Tuesday. Recent content highlights KB5089573 from May 2026, which introduced a Low Latency Profile to improve responsiveness in Start, Search, and Action Center, added the ability to choose the C:\Users folder name during setup, and included Secure Boot preparation and AI-related updates. The tag also covers installation issues like EFI error 0x800f0922 and fixes for Event ID 57 noise in CertificateServicesClient. These previews serve as a staging ground for upcoming mandatory updates.
