Downgrade windows 7 version?

[ep3w]

I currently have ultimate installed and I am wondering if there is any way to "downgrade" this to professional without reinstalling? I have tried googling it but have only found things about upgrading versions.

No.

If Win 7 Ult is already installed, and running fine, then why downgrade?

 

[ep3w]

No.

I was afraid that was the answer.

I ended up getting the educational deal for Pro, but I had already installed ultimate before as a trial. Wasn't really thinking when I installed it and was hoping I could avoid reinstalling everything again.

I'm in the same boat - except I had a good idea there was no way to downgrade.

Oh well, I need to upgrade to SL on my Hackintosh anyway, might as well wipe the whole machine and start over.
