Hi, I want to know how i can convert my student only win 7 pro only windows to utlimate is it possible? please help me thx
You can modify the ei.cfg file so that when you install it goes in as Ultimate rather than Professional HOWEVER, your key is going to remain one for Professional, and it becomes useless if you install as Ultimate. It's pretty unlikely you even need the extra features in Ultimate. Just install Professional normally and use your inexpensive key and you should be fine.
Alternatively, install the professional, and use the Anytime Upgrade if you like. Search the forum for more info.
