There's a couple ways to kill programs that you can't seem to find.
Start-->Run...--> msconfig -->Ok
Click on the "Startup" tab. The checked programs are the ones that run upon startup. Uncheck the ones you don't want (which should be everything but anti-virus software). Then click "Ok" and you'll have to restart, etc.
That can be used in conjunction with the following: Start-->Settings-->Control Panel-->Add/Remove Programs Then just click on whatever you want gone and it should take it off. This completely removes the programs from the computer.
If you just want to end a program without deleting it and don't want to go through the first procedure, hitting Ctrl/Alt/Delete then selecting the program then "End Task" should end it.
Hope this helps.
