Extend Activation

Are you testing out Vista's features and compatibility but not sure if you want to go ahead and activate it? Microsoft understands. It has built a software licensing manager into the new OS that lets you extend the activation period. At the Start menu's search bar, simply type slmgr -rearm to get another 30 days. You can do this a maximum of three times before Microsoft blocks further extension periods. And once you're locked out, that's it.
