Here's a nice little trick that i've picked up tonight... First open the command prompt with the admin rights.. Just by right clicking on command prompt in the start menu and click on "run as admin" and type this in: rundll32 slc.dll, SLRearmwindows Then hit enter and reboot... What this does is reset the activation time for windows vista.. It's great if you only got like 1 left or your on ur last day of running windows vista before it has to be activated.. Have fun
