Please do not attempt this if you are not used to using the Command Prompt in windows.
Run the Microsoft Windows Resource Checker tool, also known as “System File Checker” or “sfc”. This tool scans and verifies the integrity of all protected system files and replaces incorrect versions with correct versions.
- Right click on the Start button of Windows and choose: Command Prompt (Admin). If you don’t see this, instead choose: Windows PowerShell (Admin).
- Behind the prompt type:
sfc /scannow
(include the space in the command) - Wait until the process completes – this usually doesn’t take longer than 20 minutes.
- Restart your computer.
