Teach you how to protect Windows 7 product key security

Windows 7 RTM has been released for a while, and Windows 7 GA will be available on October 22, with massive installation and deployment. Neither the company nor the individual wants to infringe on their genuine rights. Especially after the large-scale deployment of Windows 7 in the enterprise, some employees may maliciously use some tools to extract the product key of the current Windows 7 system, resulting in the loss of enterprise IT assets, and more likely to cause attacks caused by key leakage. So how can individual users or corporate ITPro effectively prevent such problems from happening? !

Remember the Windows Authorization Management Tool — slmgr.vbs? Use this tool to help users prevent product key leaks. Run CMD as an administrator and execute “slmgr.vbs /? & rdquo; (Note: the actual operation can omit the extension .vbs), can get the parameters of slmgr, click the "OK" button to display the parameter description of the next page.

On the second page we can see the “/cpky” parameter, as explained in the description, use this parameter to clear the product key from the registry. This can effectively prevent malicious users from using the serial number viewer or script program that is streamed online to snoop the Windows 7 product key, thus avoiding the leakage of the product key.

Tips for the end of the text, the implementation of the "slmgr /cpky" rd command; must be the administrator status, otherwise the following error will be prompted.
