Microsoft has released the KB5127936 preview cumulative update for Windows 11 versions 25H2 and 26H2, featuring 41 changes and improvements. This optional, non-security update can be installed through the Microsoft Update Catalog or by checking for updates in Windows Settings. Unlike regular monthly updates, preview releases allow users and IT administrators to test new features before they become available to the general population during the next Patch Tuesday rollout.
The update includes several notable enhancements: the File Explorer context menu is now faster and more customizable, allowing users to select which app extensions and commands appear; Cloud rebuild can now reinstall Windows without requiring USB media by downloading images directly from Windows Update; and Xbox mode features a refreshed Gaming Task View with improved navigation. Additional improvements address privacy settings organization, automatic Wi-Fi profile reuse during recovery, a restore summary for device transitions, and adaptive hibernation policy refinements. Microsoft also reminded users that updated Secure Boot certificates are being deployed to replace expiring 2011 certificates.
