One of the developers of both Vista and 7 left a simple command line trick in the source code for both operating systems that allows you to tack an extra 120 days onto your activation period. The process is simple:
* Click the Start button on your task bar.
* Type cmd into the search box at the bottom of the menu. Press enter.
* Type slmgr -rearm at the command prompt. Press enter.
* Restart your machine as instructed.
That’s it! You now have 120 more days to activate.
* Click the Start button on your task bar.
* Type cmd into the search box at the bottom of the menu. Press enter.
* Type slmgr -rearm at the command prompt. Press enter.
* Restart your machine as instructed.
That’s it! You now have 120 more days to activate.
