What Happened To My Microsoft Solitaire
Best Answer: The programs on your start menu are ordered based on how frequently you use them, so most likely you have used some other program more than them. To get them back, either open them from the 'All Programs' list on the start menu and they should automatically reappear. You could also right click them, and click 'Pin to start menu' and they should permanently be placed there, unless you manually remove them. *Edit #2* Microsoft doesn't distribute the games individually, so the only way to reinstall them is with your Windows XP disk. If you don't have one, many computer shops might lend you one or reinstall the games for you free of charge (If they operate like the one I used to work at). *Edit #1* Since they are completely gone, they might have gotten uninstalled, deleted or corrupted somehow. 
To get the back or repair them, open up the control panel, then open up 'Add or remove programs.'
