About this tag
KB5089573 is an optional preview cumulative update released by Microsoft on May 26, 2026, for Windows 11 versions 24H2 and 25H2. It delivers faster shell interactions, including quicker Start, Search, and app launches, along with Shared Audio and Multi-App Camera support. The update also fixes a critical installation failure (error 0x800f0922) that caused the May 12 security update KB5089549 to roll back on some PCs due to insufficient EFI System Partition space. Additionally, KB5089573 enables users to customize the C:\Users folder name during fresh Windows 11 setup. This update is part of Microsoft's broader effort to improve Windows 11 responsiveness and address servicing reliability.
