You can delete them that way or in the start menu are the games listed there. Alot of times they have an uninstall option there. But you can delete or remove the games any way you can.
yeah i see skyrim in the start menu but theres no uninstall option. it only has the exe to play the game. if i delete it off the harddrive without properly uninstalling it, will it still be in the start menu? because thats what im trying to fix
