I recently had to resurrect a backup installation of Win 7 Home premium. It was/is a vanilla installation and everything pretty much works fine except for the main keyboard digits. Plain (unshifted), vanilla digit keys 1,2,3,8,9,0 launch Win Explorer while digits 4,5,6,7 just result in a system beep. The rest of the keyboard keys including the numeric keypad digits and the shifted keyboard digits keys (!@#$…) are all OK. Multiple keyboards all exhibit the same behavior. I’ve looked in the registry for Win Explorer options but find nothing related.
This is extremely annoying as muscle memory automatically goes for the keyboard digits to enter a number. Any ideas , suggestions on what is happening or possible fixes?
