How can I find a Windows 8 installation corresponds to which product key when I have multiple Windows 8 keys?

I have two license keys for Windows 8 and installed them on two PCs. Now I need to uninstall one of them from one of the PCs. But how could I know the product key of the Windows 8 that I uninstalled? In other words, I have two product keys with me and just don't know which installs on which PC.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Use Recover Keys ( That will give you the key of the running system. You can match up from there.  I use Recover Keys myself.
