These two free apps are Piriform CCleaner and Auslogics Disk Defrag, i call them "CC" and "DD" for short, because i usually run them by typing "cc" and "dd" in the "Run" box to call them. (surely, this needs you change the default "Path" value in the "Environment Variables")
How to
- Run CC to clean out the junk files and registry safely
- Run DD to defragment C volume
