Well. if it only a few, you could rebuild them from the .exes in program files. https://www.sevenforums.com/tutorials/296-start-menu-all-programs-add-delete-shortcuts.html
This SFC /SCANNOW Command - System File Checker may work and you may need to run it 3 times with reboots between. Otherwise try the system restore WHS suggested. System Restore
Any luck with the system file check or system restore?
