Some ideas to help keep your computer easier to use and running better.

Get A Virus Scanner
It's really impossible to emphasize this one too much. These days, all you have to do is view an email to get a virus. A virus scanner is extremely recommended. McAfee is what I use.
Organizing Programs
By default, every program you install puts its shortcuts in your Start menu's Programs folder. After awhile you've got a huge list of things there. Try creating a few folders under that and moving things around to organize: "Games", "Utilities", "Demos", and anything else you need. This can help you find things quicker than looking at a huge list.
Note: if you move existing Programs folders on your computer, it will very likely mess up the uninstaller so they won't remove the Programs folders--but you can do that yourself.. If you install things using folders from the start, uninstallers will work fine.
