A lot of people will occasionally run a few small applications as part of a general maintenance to keep their computers clean. Since I know my systems are always clean I just run CCleaner and defrag. I was considering writing an article on the Lunarsoft Wiki about general practices to help keep your system performing well. Before getting into this I felt it would be best to hear what else people do when they fine tune/tidy up their computers.
How often do you defrag and perform disk cleanups? What other tasks do you do when you're getting ready for this maintenance? How often do you perform said tasks? Do you do them manually or automatically (scheduled)? If you could schedule them, would you like to read on how you could make it automatic?
Let's hear what you do and your thoughts. :)
