Hack Windows Vista Activation

How miserly is that Windows Vista gives you only one month of trial for a whole damn Operating system? I can understand it for a registry cleaner or an antivirus software. But for an OS, isn’t it too low? So here is a legal way to increase it and forget about registering by pay.

1. check the activation expiry date with the command: slmgr -xpr
2. Go to bottom left corner
3. Navigate to this path:
   HKLM\SOFTWARE \Microsoft\Windows NT\CurrentVersion\SL
4. Double-click SkipRearm and change the value to 1.
5. Note: this registry hack does not make any sense on a machine which has already been activated!
6. Now remember to run the 30 day extension command: slmgr -rearm
7. Restart the machine.  After it reboots, run slmgr -xpr and check the expiry date.
8. Check the registry setting SkipRearm, slmgr resets the value to zero.
