If the protected file is corrupted or changed, SFC will repair and replace it with the correct copy from the %systemroot%\system32\dllcache folder. If the file cache is found to be altered or corrupted, SFC will also attempt to repair the file cache.

4. Run a DISM scan

If SFC can't fix a protected system file, you have another tool to try: DISM, which is even more powerful.

Step 1: Right-click the Start menu and choose Command Prompt (Admin).

Step 2: Type DISM /Online /Cleanup-Image /RestoreHealth and press "Enter." Wait for the tool to fix any corrupted files. When it's done, restart your computer and check if you can now upgrade to Windows 11.
