      If you have Windows 7 product key then simply right-click on your “my computer” and then click on “properties” and click on change product key. Enter your new product key and then click on activate.

  2. Hi,
    I use my product key but still cannot. It always say double check. Even it still true the number product key. It say unlincends. How should I do?

  3. I am trying to use the CMD command in Microsoft Windows Version 6.1.7601 (2009) and it won’t work. I keep getting the error:
    ERROR: Description = Invalid query

    What should I do?

    1. Techexpert

      I have double-checked the syntax and I found it is the correct one. Might be possible that it is not working in 6.1 version. Alternatively, you may use a third party app to get the keys. Using the app to get the product key is completely safe.
