I wanted to know about windows activation of Windows 7 premium. I am frequently getting a message to activate it,and it requires a 'product key'.I do. Windows 7 activation period. If you don’t activate Windows 7 within 30 days after installation. What happens after the trial period of Windows has expired? Oct 19, 2010 I tried to recover from a virus that Windows 7 and McAfee failed to detect by reinstalling. The activation period has expired => Activate.

If this is an OEM laptop, try contacting your OEM's Tech Support and see if you can get the product key from them. If you bothered to register your laptop with the OEM through the use of their bloatware (preinstalled software), you may get some luck.

I'm going out on a limb here but if you provide them your information and serial number of the laptop (which is unique to every machine manufactured from the OEM) they may be able to provide you the CD key that came with the machine. – May 3 '12 at 19:08. @myselfpoddar That can sometimes happen if you have installed any dodgy software. From an admin command promt try slmgr /dlv - after a couple of seconds this will pop a window displaying license info including the status of your current license.

For ease of use open the command prompt this way - Start Menu - All Programs - Accessories - right click on Command Prompt and select Run as Administrator. This is a useful facility for evaluation/testing - eventually you should buy a license. – May 27 '12 at 11:26.
