Where can I find the computer product key？

　　The product key of a Windows system computer can be viewed by entering a specific code at the command prompt. Here, taking a Windows7 system computer as an example, the specific operation method is illustrated:

　　1. Click the Start menu button in the lower left corner of the system desktop to find and open the Run application in all programs.

　　2. Enter the command line CMD in the Run window, open the cmd command window, and right-click on the top bar of the window to select Run as Administrator.

　　3. Enter slmgr.vbs -dlv (slmgr.vbs after slmgr.vbs plus -dlv) in the newly popped CMD command window, and press Enter to confirm.

　　4. The Windows Script Host window pops up, where you can view the system name, activation ID, product key certificate (i.e. product key), license status and other information.
