" Windows 2000 or XP doesn't let you add or remove all the programs it installs by default."

If you want a total control of your computer, just boot it from the old DOS and XTREEGOLD for DOS is an excellent tool.
You will find things that never believed to exist in your computer and you can kill anything you want.
If you don't like DOS, just boot the computer from Linux and run Midnight Commander.

Stupidity also evolves!
