Overview
- Microsoft released the KB5083631 optional preview for Windows 11, available in Settings under Windows Update or as .msu downloads from the Microsoft Update Catalog.
- Xbox mode adds a full‑screen, controller‑friendly interface for PCs and can be launched from the Xbox app, Game Bar settings, or with the Windows key + F11 shortcut.
- Feature activation is staged on Microsoft’s servers, so some PCs will see Xbox mode later, and power users can force it on using the third‑party ViveTool.
- The update fixes File Explorer so folders keep the same view across apps and speeds up apps that run at startup.
- Installing KB5083631 moves 25H2 to Build 26200.8328 and 24H2 to 26100.8328, and Microsoft lists 34 quality changes with no major known issues reported.
