You may know that you can extend the period that you can use Windows Vista without activation. Microsoft gives you 30 days before you do need to activate the operating system. The Windows operating system supports a command that you can run to extend the period three times for 30 days each, so that you can use the operating system for 120 days without activation.
Ryan from Cybernet published an article today that explains how every Windows Vista user can extend the activation period by the factor three raising the total period that Windows Vista can be run without activation to 360 days.
The first steps are basically the same as before. Run the command prompt as an administrator, you can do this by starting cmd and pressing CTRL + SHIFT + ENTER. Type "slmgr -rearm" and hit return. The activation period will be reset to another 30 days after a reboot. To check if this procedure was successful you can type "slmgr -xpr" at the same command prompt after the reboot.
This was the usual way of extending the Windows Vista activation period from 30 to 120 days.
We are now going to increase this period so that you can use the system for 360 days before you need to activate Windows Vista. Open the Registry by entering "regedit" on the command prompt or run box, and navigate to the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SL
Right-click the SkipRearm key and choose to modify it. Change the value to 1 and close the Registry editor again. Start the command prompt as an administrator and type "slmgr -rearm". Reboot the PC and the Vista activation period was reset to another 30 days. This can be done eight times.
To outline the process again:
This extends the Windows Vista activation period to 360 days.
