Microsoft has published a blog post detailing the WGA – Windows Genuine Advantage – measures undertaken in Windows 7. Windows 7 uses a 30 day grace activation period in which the user should activate the operating system with a product key. We already mentioned that the same methods of extending the activation period – or more precisely to reset it – can be applied to Windows 7 (read: extend windows 7 trial period)
Windows 7 will begin informing the user that the operating system is not activated beginning three days after installation. The message will be displayed in the System Tray area with the option to activate the operating system right away. Windows 7 will from then on until day 27 inform the user the same way that the operating system has not been activated. After day 27th of not activating Windows 7 the frequency will increase to one notification every 4 hours. The notification will also contain additional information about the consequences of not updating the operating system.
After the 30 day activation period Windows 7 will post a notification every 60 minutes. It will also display a persistent desktop notification that Windows is not genuine and another message when the Control Panel is launched. Windows 7 will also turn the desktop background to the color black. This can be changed but the desktop will be reverted to black every 60 minutes. Lastly users will not be able to receive optional Windows update until their copy of Windows 7 has been activated.
