How do I repair corrupted system files after upgrading to Windows 10?
After upgrading to Windows 10, the system reports a file corruption error during startup. Attempts to delete the specified files and uninstall the updates have not worked. How can I fix this issue? If I have to reinstall the system, how can I install an older version while keeping my personal files?

I went through the exact same worst case scenario last year. I did a Windows upgrade, everything seemed fine, and then—boom—total system file corruption. I couldn't even get past the loading screen, and I honestly thought I’d lost every single photo and work project on my drive. It’s a terrifying feeling.
Before you do anything else, try the standard revive commands. Open your Command Prompt (as Admin) and run sfc /scannow. If that doesn't bite, try the DISM command (DISM /Online /Cleanup-Image /RestoreHealth).When my system was too far gone for Windows to fix itself, I stopped messing with the OS and focused on saving my files first. I used Stellar Data Recovery and it was a total lifesaver. It managed to dig through the corrupted mess and pull my data out when I thought it was gone for good.If you're worried about your files, don’t keep stress-testing the system. Just run a scan with Stellar's free version first to see what's still alive.
Run these two commands for repairing the system:
DISM /Online /Cleanup-Image /RestoreHealthsfc /scannowThis scan will also take some time (10-20 minutes). It will automatically find and replace any corrupted files it detects.
+1. This is a very helpful fix!
Actually, I would recommend that you use the Media Creation Tool and select the option to upgrade this PC whilst keeping your personal files.
Seen this after upgrades, system starts throwing corruption errors out of nowhere.Try sfc /scannow, if not then Startup Repair or restore. If it still doesn’t fix, reinstall is the only way.
