Problem Steps Recorder
Windows 7 has a nice feature called the Problem Steps Recorder. It can help you demonstrate a problem you are experiencing with a computer. When you are done, you will have a nice document that lists all the steps you took and corresponding screen captures. It's pretty easy to use.
