You would be surprised to know what you can do from command line of Windows XP Pro. Windows XP Pro comes equipped with a powerful set of command line utilities. If you want to know what they are and how to run them and a good decription of each of them...go no futher.. Its available right in your computer. This is again not a tip or trick or tweak of any kind but information that is as powerful as any of the tips/tricks. Open START-RUN window and type C:\WINDOWS\Help\ntcmds.chm Also you may not know that .chm is the windows help file extension. I find the Windows Help to be a very good starting point to learn all the power and resources of Windows environment. I like section of NETSH and Windows scripting host among other things.
