Windows 11 27H2 update rumored to be a full operating system swap
Anonymous sources report that Microsoft is preparing the Windows 11 27H2 update, which will arrive next year as a major overhaul rather than a new version number.

Testing schedule shifts earlier
Testing for this release will begin significantly earlier than usual. Previous versions like 26H2 and 25H2 typically started previews in June, but the timeline for 27H2 is different.
Focus on quality changes
Reports indicate a big focus on quality alongside sizeable upgrades to the underlying platform. The update will not be released as Windows 12 despite the magnitude of the changes.
New default wallpaper arrives
Users will see a new default wallpaper replacing the current Bloom background. This visual change marks the departure from the design used since the operating system first launched.
