Episode 1325 (1:49:40)

Steve from New Jersey

Steve has a laptop running Windows Vista. It was running pretty good until last week and then he updated to Windows 7. It created the sub directory for Windows.old. Can he get rid of it? Leo says he can simply delete it. The best way to get rid of it is through the Windows Cleanup tool. That will get rid of it plus other files like temporary files, clearing cache, cookies, etc.
