I just built my first pc and purchased windows 7 with it but for some reason it says activation has expired. Windows 7 Vienna Transformation Pack.

After the activation grace period, you enter limited functionality mode. This typically means: • 20 Second wait when starting Windows, with a screen saying activate now. • Solid Black desktop wallpaper • Nag screens popping up at random • Notification popup at random • You will still be able to do most Windows update, but anything through 'Windows Genuine Advantage' will fail, this includes certain programs (e.g.

Microsoft Security Essentials) and features such as many downloads from Microsoft.com. Also, you can run slmgr -rearm (From the command prompt) a few times in order to extend the deadline by 30 days.

I tried to recover from a virus that Windows 7 and McAfee failed to detect by reinstalling Windows System 7. The reason I did this was that earlier I had been told that if I upgraded from XP to System 7 a previous virus would be removed. That worked the first time. Sure enough, the second installation of Windows System 7 removed the second virus as far as I can tell. Now I see the following message in the lower right had corner of the screen: Windows 7 - Build 7600 - This copy of Windows is not genuine Each time I reboot Windows 7 I get the following message: Windows Activation - Activate Windows now - The activation period has expired =>Activate now =>Ask me later - Cancel - 0XC004F009 Can something be done about this so that Windows 7 is kept up to date and considered legal?
