How to edit or change Windows 8 Product Key

Had problem entering new Windows 8 product key and activating it with DNS error. Lookup and found we can change the product key the same way as how to change in Windows 7.


  1. Run command prompt as Administrator
  2. Type ‘slmgr.vbs /ipk’ followed by your TechNet or MSDN product key.

  3. Last step, will be activating the Windows after changing the key.

    slmgr.vbs –ato

You’ll see a pop up message box once you have successfully activated the product.
