To use Windows 7, you must activate it within 30 days of installation. However, you can "trick" this activation process with Windows Loader. The activation process with Windows Loader is not supported by Microsoft. You can also use the rearm command to extend the activation grace period by 3 times so you can use Windows for 120 days.
