Do you need to change your product key so you can activate Windows 8 properly? After installing Windows 8, you’ll find that there is no option to enter a product key under Computer properties. Or, at least I did not see it. Luckily, the good old Command Prompt and slmgr.vbs tools came to rescue. Just follow this tutorial to change Windows 8 product key using Command Prompt and slmgr.vbs.

  1. Move the mouse cursor to the bottom right corner of the screen, click the Search icon.
  2. Type in cmd in the search box, then right-click on the “Command Prompt” icon on the top-left of the search result page. A tick sign appears on the icon.

  3. Click on the Run as Administrator icon from the bottom options.
