You will probably never use the control panel to add a program, but you have to use the control panel to remove a program. The only reason you should ever really remove a program, though, is if your hard drive runs out of space.
Open the control panel.
Open add or remove programs.
This is add or remove programs.
This completes adding or removing programs.
Be careful because when you remove a program, the only way to get it back is to reinstall it.
