I wear a lot of hats...

"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.

Machines upgraded during the free upgrade offer or by purchasing from the windows store use a generic key and have a digital entitlement stored in the cloud. So it is neither the windows 7 key nor the key you are pulling after the upgrade.
