Question

How do I find out the key that was used to install my Windows 7 Professional?

Answer 1

You should have the serial key for Windows on a sticker on your computer. If your computer didn't come with Windows 7, and you bought this Windows version later, then the key should be located with the manual that comes with Windows 7. If you still can not find the key, then use a key finder program. One program that helps you recover your lost product keys of software installed on your computer, including Windows, is Product Key Finder. You can find more information about this program at http://product-key-finder.software.informer.com/.

Answer 2

If you have created a System Restore point before, and can still remember the password you used at that time, then you can restore Windows to that point, and log in with that password. To complete this procedure, you must boot the computer from windows installation disk or system recovery disk to make use of system restore function.
