Chapter 20: Handling Routine Maintenance and Troubleshooting
When Disk Cleanup finishes, I recommend that you restart your computer and con-
sider the two additional options it provides:
Program Clean Up
Helps you free up space by removing programs that you do not use
System Restore and Shadow Copy Clean Up
