There’s a soon to be well known trick that can extend the trial period up to 120 days.
Do so, and you’ll see that the activation period has been reset to 30 days.
you’ve got the option to only use this command 3 times before Microsoft smacks you down.
This answer is less obvious.
Most people don’t have MSDN, however.
There are various “other” ways to get a copy of the Vista CD.
I suspect they can hook you up, but remember it’s just a trial copy.
I don’t advocate piracy.
Alternatively, you could buy a copy.
As far as I can tell, this is completely bogus, and shouldn’t even be attempted.
Honestly, it’s best to just buy a new computer with Vista already installed.
This hack is obviously illegal, unsupported by Microsoft, and likely to break with future patches to Vista.
I have verified that this works with some friends.
