Windows 11's May update turns any PC into a console with Xbox full-screen mode

The most eye-catching part of Windows 11's May 2026 update isn't a security patch - it's Xbox full-screen mode landing on ordinary PCs. Switch it on and Windows drops into a console-style, controller-first dashboard that hides the desktop and trims background activity to leave more resources for the game.

It reached Windows 11 24H2 and 25H2 machines, and you turn it on under Settings > Gaming > Xbox mode or with Windows + F11. It's built for handhelds and gaming laptops, but any PC can use it. The same update also sped up File Explorer and taught it to open more archive formats, added substring file search (type "april" to find "MeetingNotesApril"), and brought subtle haptic feedback to supported pens.

None of it is essential, but the File Explorer and search changes genuinely help day to day. Worth grabbing once the month's update has settled in.

New features usually arrive bundled with the monthly cumulative update - which is also where the occasional bug hides. Tendvane's Windows Update panel confirms you're current, and its restore-point tool lets you take a snapshot before a big update so you can roll back if a new build misbehaves.
