License problem with Windows 7 Ultimate

[Droiyan3]

Hi all,

I've bought a new PC with a preinstalled Win 7 ultimate 32 bit. After some time i've tried doing the updates and found out that it was a pirated one. I've asked one of my friends to buy me a serial and have wanted to activate win 7 through this key. I did not find however a way to this except one. I've forgoten which command it was but i've run it from the cmd and i've changed it and it even worked for 2 weeks. Now its says that my system is still pirated.

later on i've found out that the actual serial key is for windows 7 pro.

my question is is it possible to downgrade to Win 7 pro from win 7 Ultimate and then somehow change the serial key to the licensed one ?

thanks

In the Properties of (My) Computer, at the bottom, do you have a link that says Change Product Key?

No, you can not downgrade to Pro. Otherwise you need totally clean reinstall to pro. But As the Tripredacus Said you may find the Master Product key (Which means the Big Volume OEM account Product key) at internet to change your product Key or use keygen to change your product key.
