Your computer is getting slower and slower? MSCONFIG will allow you to control the software that starts up with the computer. With Vista or Windows 7, simply type msconfig in the Windows search tool (above the "start" button). Then press the startup tap. Here you will find a list of all the programs that startup with the computer. You don't need any, but the choice is yours.
If you still have Windows XP, it is time to change computers. However, MSCONFIG will still work (type msconfig.exe under "run")
Control and scroll wheel.
