How to switch between Windows 7 Editions?
I have Windows 7 Ultimate RTM installed on my laptop. It's currently on a 30 day trial (I'm an MSDN subscriber through work). Well, at work we now have Windows 7 Enterprise available (this is a work laptop).
Is it possible for me to somehow use my Win 7 Enterprise key to activate my Win 7 Ultimate installation? I don't mind having it "reduced" to the Enterprise version...I just don't want to have to re-install.
I tried activating Win 7 Ultimate on my system with the Enterprise key and it won't take it. It knows it's for a different edition.
Any ideas?
