How to Install Windows 11 25H2 Repair Version

Installing a repair version of Windows 11 (also known as an in-place upgrade) is one of the most effective ways to fix system issues without losing your files, apps, or settings. If you’re facing crashes, update errors, or corrupted system files, reinstalling Windows using the latest version—such as Windows 11 25H2—can restore stability.
