I had to activate. It just depends on which version you are using. I had a "professionnal" version that didn't need any activation at all, but my "home" version needed activation, the same for my neighbors.
You have a period in which you can still use it without activation, but after a while I think you get limited functionnalities, I don't remember.
I have to admit I'm talking only of Professional edition. With "home" one can't even upgrade to a larger disc!!!!!!! How's that for M(qualcosa)s controlling how we use "our own" pc's!!!!!!!!! So go and get Professional edition it's completely open ended as it should be!!!
If Vista comes with limited use or telephone registration etc, it won't sell very well in Europe. I think the EU will force M(qualcosa)s to open it up as I stated earlier to limit it's use by "having to" activate it contravenes the decision of the court against M(qualcosa)s
