11. Repair your registry
The simplest way to repair your registry is to use a dedicated tool, such as CCleaner. Don’t forget to first backup your registry in case anything goes wrong.
You can also use Microsoft’s System File Checker to check for system file corruption. The utility verifies the integrity of all protected system files and repairs files with problems when possible.
Here’s how to run an SFC scan:
- Press the Windows key to go to Start > type cmd
- Hit Control + Shift + Enter to run Command Prompt as Administrator
3. Now type the sfc /scannow command > hit Enter
4. Wait for the scanning process to complete and then restart your computer. All corrupted files will be replaced on reboot.
