 This will add 30 days to your activation timer. Put a space between slmgr and -rearm. It may take a few seconds for the confirmation to appear.
 Your new 30-day extension will take effect right away.
 You can repeat the command three times. This will give you 120 days total extension. This is within the terms of the Microsoft EULA.


Open the Command Prompt as an administrator and type slmgr -xpr. A notification with the remaining time will appear shortly.
 Editing the Windows Registry can increase the extension to an entire year. Performing this extension is not as accepted by Microsoft.

 Click "OK" to save the changes to the key. This will extend the renewal time by 240 days, for a total of one year of renewals., You can do this each month for the next eight months.
 Once your year of renewals is up, reinstall Vista from scratch and start all over again. Vista can be reinstalled and running again in about an hour.
