I'm looking to downgrade the version of windows 7 I have installed on my machine from Ultimate to Professional. I installed from and ISO I got off the MSDN but have just found out that I'm supposed to be using a retail licence on my machine. We've only got retail licences for Professional and I don't want to use and up the MSDN Licenses we have.

Is there a way to do this?

No, I guess you can't do that. The installed OS is not the same, it's not just about the key. (Maybe you could use the Upgrade point at install with a Professional disk.)

Simply no, you can't (: You must reinstall your OS, to use another Edition.

NB! Microsoft offers to MS Windows 7 Ultimate and MS Windows 7 Professional owners, free downgrade to Windows Vista Ultimate / Business. You can find more about it on Microsoft TechNet if you want.
