Keep your computer or laptop running effeciently and smoothly:
1. Set disk defragmenter to run daily
2. Run disk cleanup regularly (at least once a week)
3. I use a program called Tracks Eraser Pro to clean anything the built in Windows disk cleanup does not
4. Be sure to keep your antivirus and Windows up to date
5. Back up your data
6. Create a set of Windows recovery disks
