Clever use of the slmgr command to protect Win7 key security

No matter whether it is a business or an individual, you do not want your copyright rights to be violated. Especially after deploying Windows 7 in large quantities in enterprises, 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 ITPros effectively prevent such problems from happening? !

Remember the Windows license management tool - slmgr.vbs? Use this tool to help users prevent product key leaks. Run CMD as an administrator and execute "slmgr.vbs/?" (Note: the actual operation can omit the extension .vbs), you 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, which, as explained in the description, can be used 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.

Friendly reminder, the "slmgr/cpky" command must be an administrator, otherwise an error will be prompted.
