How to reset a windows 7 admin password?

#1

I have two Windows computer, one is a laptop for daily use and one is old pc for file storage and backup. Both of the computers are password protected. It has been a long time not logging in the old pc and seems I just forgot the password after coming back from xmas holiday. Is there any way to reset or restore the password without reinstalling the OS?
