I got a Vista Business CD key. Am wondering if I use that CD key on Ultimate, will it works ?
Thanks for the reply. Try ask in Vista sub board but no reply. Kinda urgent to know so open up this thread.

i dont think will work.... diff version , diff price...

vista business cd key can be used on windows xp but not to vista ultimate

yeah bro microsoft gimmick you cant

o_O"?

means winxp sp2 key can use at vista business de?

Haha...I dont think it works...

knock some sense in ur head, if vista business key can be used to activate vista ultimate, who would spend the extra cash to purchase vista ultimate?

I think you can activate the ultimate disc to business during installation. Also depends on version. A MSDN key won't activate a retail disc and vice versa
