Just a general topic. Wanted to see if there were things I could be missing when optimizing a computer (you know, the one that someone has had for a year, and done nothing but use, no file maintenance, etc).

I will do a few things. Simple things really, like clear all the temp folders, find all backup files that aren't needed and get rid of them, uninstall useless programs, clear the startup folder, use msconfig to clean the system startup more, defrag, stuff like that. In Win9x systems, in the system configuration, I will change the role of the computer from desktop computer to network file server. I heard this worked, but really never noticed a difference. There are more, but these are the ones that come to mind, the main ones I start with. What do you all do? Any registry tweaks that anyone uses?
