Why Microsoft is automatically upgrading certain Windows 11 PCs to version 25H2 and why you shouldn't try to block it
Microsoft is starting to automatically install the latest feature update (25H2) on older Windows 11 versions like 23H2 because they have reached End-of-Service and pose a security risk without patches.
Windows 11's latest update is here, and your PC will receive it automatically. As is the usual case for versions of Windows, Microsoft has ended support for Windows 11 version 23H2, which initially rolled out in 2023. To help ensure PCs are up to date, Microsoft will push systems to Windows 11 version 25H2.
"As of November 11, 2025, Home and Pro editions of Windows 11, version 23H2 have reached end of servicing," explains Microsoft. "Enterprise and Education editions of version 23H2 will continue to receive monthly security updates until November 10, 2026."
Unless your PC running Windows 11 version 23H2 is managed by an IT department or is ineligible, it will be updated automatically.
As pointed out by our colleagues at TechRadar, some PCs with older processors are not eligible to upgrade to Windows 11 version 25H2. Only CPUs that are pretty old fall into that category, so there's a good chance your computer is not affected by the limitation.
As for those currently running Windows 11 version 23H2, it's important to upgrade to Windows 11 to receive security updates and bug fixes. There are also some new features that are on the way to Windows 11 version 25H2, though they will also ship to Windows 11 version 24H2.
What's new in Windows 11 version 25H2?
For everyday users, the most important takeaway is that Windows 11 versions 25H2 and 24H2 have the same feature set.
Features that ship in the future, such as the improved Start menu, will make their way to both of the most recent versions of Windows. An improved gaming experience will ship to both Windows 11 version 25H2 and Windows 11 version 24H2 as well.
All the latest news, reviews, and guides for Windows and Xbox diehards.
If your PC is on Windows 11 version 23H2, you will see new features that debuted with Windows 11 version 24H2 after you upgrade. That was a sizeable update that included both under-the-hood improvements and surface-level features.
