Microsoft introduced an update to the out-of-box experience (OOBE) for Windows 11, identified as KB5095189, targeting versions 25H2 and 24H2. This update includes enhancements and fixes, coinciding with additional updates KB5102558 and KB5095615 from the June C-release preview update (KB5095093). A major fix addresses a storage issue caused by the Capability Access Manager process, which was consuming significant disk space. Another fix resolves a malfunction affecting Shell components, impacting the Start menu, Search bar, Settings, Taskbar, and File Explorer, primarily on provisioned PCs due to compatibility issues with XAML. This bug had been present since July 2025 and is being resolved with updates released starting June 23, 2026 (KB5095093), with full deployment expected in the following month. Users are advised to use previous workarounds until the fix is fully available. Further details can be found in support article KB5072911 on Microsoft's website.
