Vista Horizons

Did you know you can have up to 120 days before activation of your copy of Windows Vista? The secret lies within a little program know as the Software License Manager (SLMGR).

SLMGR is a command line tool and you have to run it with admin privileges. That is done by simply running cmd from the Start menu and, instead of pressing enter, you press CTRL+SHIFT+Enter (very cool).

SLMGR lets you extend the activation 30 days from the time you run the app. You can only do this a couple times and it's worthless to do it right after you install Vista because it wouldn't buy you any time. Just wait a couple weeks or until closer to your original activation time.

You can read all the details about SLMGR and how to perform this trick over on Windows Secrets.
