3. Repair or Reinstall Windows
If sections one and two did not resolve your issue, this may indicate an issue with your Windows installation. You can use the steps below to attempt to repair the installation.
Repair Windows
First, use the System File Consistency (SFC) check utility to verify the integrity of core Windows files.
Open Command Prompt as Administrator.
Run: sfc /scannow
Follow any prompts for resolving the issues that it finds.
On Windows 8.1 or newer, you can use the DISM utility to further inspect the system for issues and attempt to repair them.
Open Command Prompt as Administrator.
Run: DISM /Online /Cleanup-Image /ScanHealth
If the scan finds any issues, then run: DISM /Online /Cleanup-Image /RestoreHealth
Note: The DISM commands can take upwards of 10 minutes to complete, and may appear stuck. Give them time and let them finish.
Reinstall Windows
Consult your computer’s manual or your computer manufacturer's website for instructions on reinstalling Windows. Be sure you backup your data before reinstalling, as it may be wiped during the process.
