Windows has built-in tools to find and replace missing system files automatically.

• Press the Windows Key.

• Right-click Command Prompt and choose Run as administrator.
• Type sfc /scannow and press Enter.
• Wait for the scan to finish.
• Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.

2. Reinstall the Affected Program

5. Use System Restore
