Manual Maintenance in Windows 11

Over time, system files on your Windows PC can become corrupted due to sudden power outages, improper shutdowns, malware infections, failing storage drives, or even software conflicts. When critical system files are damaged, you may experience crashes, slow performance, or error messages. Windows includes built-in repair tools like System File Checker (SFC) and DISM (Deployment Image Servicing and Management) to scan and restore corrupted files. Running these commands ensures your operating system remains stable and prevents further issues.

How to do it:

Open Command Prompt in admin mode and run sfc /scannow command.
Wait for the scanning to finish and check the result. If SFC couldn’t fix the issue, then you can use the following DISM commands (run one by one) to check and restore the image.

DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

Regularly checking for file corruption helps maintain system health and prevents unexpected problems down the line.
