Are you testing out Vista's features and compatibility but not sure if you want to go ahead and activate it?
Microsoft has built a software licensing manager into the new OS that lets you extend the activation period. Very understanding for Microsoft, considering so many have returned to XP Pro after buying a machine withh Vista installed.
At the Start menu's search bar, simply type "slmgr -rearm" to get another 30 days.
There is a maximum number of times you can "rearm" the software licensing manager.You can do rearm a maximum of three times before Microsoft blocks further extension periods.

Once you're locked out, that's it. You have to call Microsoft to unlock your computer or take it into a shop.
