Uninstalling Mah Jong from Windows Vista?

My friend is finding the games too compulsive and wants to uninstall them but finds they don't come up on the uninstall function - she has to switch some function of Windows on and off instead to shut them off - but this is just a toggle. She's looking for a more permanent solution. Any advice?|||go to control panel, add remove programs. remove it there. If that doesn't take care of it then click start button,,search files and folders, type game name in,,now delete all files it shows!|||assuming it works the same click start go to control panel, uninstall and then remove|||start menu view progames stored on there delete
