Windows 11 25H2 is coming whether you want it or not
Microsoft has started automatically upgrading eligible Windows 11 PCs to version 25H2, expanding the rollout beyond users who previously chose to install the update themselves.
Until recently, 25H2 was largely an optional upgrade offered to systems already running Windows 11 24H2. That is changing now. Home and Pro devices that are not managed by an IT department are now being moved to 25H2 through Microsoft’s automatic update process, including many PCs still running older Windows 11 releases.
For most users, this won’t be a dramatic upgrade. Version 25H2 shares the same foundation as 24H2, which means the installation is relatively small and should complete quickly with a single reboot. Think of it more as unlocking the next chapter of Windows 11 rather than installing an entirely new operating system.
The move is also important because it prepares PCs for what’s coming next. Microsoft is expected to release Windows 11 26H2 later this year, and both versions are built on the same underlying platform. By moving users to 25H2 now, Microsoft can make the eventual transition to 26H2 much faster and less disruptive.
Another reason behind the rollout is support. Systems running older Windows 11 versions are gradually falling out of Microsoft’s support window, meaning they no longer receive security updates and bug fixes. Upgrading to 25H2 extends that support lifecycle and keeps devices eligible for future updates.
If your PC hasn’t received the upgrade yet, there’s no need to worry today. Microsoft is releasing it in stages, so some devices will see it sooner than others. Users who prefer not to wait can manually check for the update through Windows Update by selecting Check for updates button.
