Windows 7 activation and update failure after updating

[pranav appu]

I had updated my windows 7 for latest version but since that it shows that windows update service is not running. But it is running under the services. Also it shows that my windows is not activated. But it was activated untill previous updation. I had run updates earlier but worked perfectly. But yesterday, it seemed to update windows update Agent and then it failed to update and activate. But NO counterfeit/pirated showing message appeared and everything else works smoothly.

Please help
