|Another thing that you can try is to try to remember when your start menu worked properly. If you can, and you have a restore point from about that time, you can use system restore to take your system back to that point. Just read about system restore in "Help and Support".|
If the system restore works, you may have some updates to install, but that's pretty easy. If it doesn't, you can restore your system back to now, and try something else.
