There are a lot of reasons you may not want to immediately activate your new installation of Windows Vista by entering your product key. Maybe you’re running it on a test machine before upgrading your gaming rig. Maybe you want to wait for better drivers to come out before you hand over your credit card. Maybe you just don’t feel like it.
But after 30 days, you’ll find that Windows has lost its patience with you and goes into a reduced-functionality mode until you enter a product key and activate Windows Vista. If that’s not enough time, don’t sweat it: There’s a way to extend the 30-day Windows Vista “grace period” to as much as 120 days, and it’s perfectly legitimate and legal.
Simply log into Windows Vista as an Administrator, launch the command prompt by clicking on the Start button and typing “cmd” into the search box (without the quotes). Press enter. Now type “slmgr –rearm” at the command line prompt and press enter. You’ve just reset the activation countdown back to 30 days.
You can repeat this process up to three times, for a total of 120 days after you install Windows Vista until you have to enter a product key and activate your copy. Microsoft, surprisingly, is fine with this, as there are legitimate uses for it. And you DO have to pay your dues sooner or later. After 120 days of Aero Glass, it's going to be pretty hard to go back to drab old XP.
And if you still haven’t made up your mind after 120 days, maybe it’s time to consider professional help.

Quem tiver um trial do Vista que experimente e por favor dê feedback pra ver se funciona ou não.
Ps: se estiver na secção errada ou qualquer coisa do género, removam ou apaguem.
