Restarting your PC is a simple and completely free method to help with disk cleanup on Windows 10. While it may seem basic, a restart can clear out temporary files and free up some system resources, especially if files are in use or locked.
How Restarting Helps with Disk Cleanup on Windows 10:
- Clears Temporary Files: When you restart, Windows automatically deletes certain temporary files that are no longer needed or in use.
- Releases Locked Files: Files that were in use and couldn't be deleted manually may be released and cleaned up during restart.
- Refreshes System Resources: Restarting can improve overall system performance by resetting processes and freeing RAM.
How to Use Restart as a Free Disk Cleanup on Windows 10 Method:
1. Close all open applications: Save your work and close programs.
2. Click on the Start menu: Or press the Windows key.
3. Select "Restart": Click on the power icon and choose "Restart."
4. Allow your PC to reboot: Wait for Windows to restart fully.
