How to Extend Vista Trial Period for Up to 120 Days

   Information

Vista gives you a 30 day trial period before you have to activate Vista or pay for a product key number. This will show you how to extend the trial period 30 days at a time for up to 3 times for a total of 120 days before you must either activate with a legally purchased product key number or uninstall Vista.

Microsoft has allowed this rearm option to extend this trial period for another 30 days for up to 3 times.

3 (rearms) x 30 (days) = 90 (days extended) + 30 (default days) = 120 days total trial period.
