Run Windows 7 free without activation for 4 months
Microsoft has made public a simple hack to keep the non-activated copy of Windows 7 running for a full 120 days before full-on nag mode sets in. All you have to do is enter "slmgr -rearm" into the command prompt at the end of every 30 day period, and your copy of Windows gets a whole new lease on life -- an action that can be repeated three times. The same command is available for Vista users.[/img]
