Press and hold (or right-click) on the app, then select Uninstall.
Select Start and look for the app or program in the list shown. There are different ways to remove apps and programs, so if you can't find the one you're looking for, you can try another location. Note that some apps and programs are built into Windows and can't be uninstalled. You can try to repair a program first, if it's just not running correctly.
