Windows 7 Activation Issue after installing updates
Hi,
I have installed windows 7 on my computer .It worked so well .And I am happy with its performance compared to vista .But recently when I tried to install an update I have got a problem saying that the Activation failed. So that I have also checked the activation key it was correct. After that I tried to revert back but it was helpless.
What should I do to clear this activation problem to update?
