If you’ve been trying out Vista for the past 25 or so days (like me), your 30 day evaluation period is about to come to conclusion. A little known fact is that Microsoft built functionality into Vista that will extend the trail period for another 30 days. Open a Command Prompt session (Start >> All Programs >> Accessories >> Command Prompt), type slmgr -rearm and hit enter. This “rearms” your activation period. You will only be allowed to rearm your computer three times. According to Microsoft this does not violate your license agreement.
