Don't have a valid product key for Windows Vista? You can still get around those pesky activation pop-ups. Vista allows you to extend your activation grace period by 120 days. With a little tweaking, you can renew your activation indefinitely. You can extend your activation even if you've been locked out of Windows.
Things You Should Know

- Type "slmgr -rearm" to get 30 more days, then reboot your computer.
- After 30 days, enter that code in Command Prompt again for 30 more days, and repeat up to 3 times, which equals 120 days.
