Windows 8 Product Key Deactivation

It’s the end of the year and I bought myself a new laptop. Although it came with Windows 8 and upgraded it to Pro, I had to install a fresh installation of Windows 8 Pro for some stupid/buggy reasons (still frustated, something with missing groups when using upgrade).

So I needed to remove the license from my old laptop and bring it over to the new one. To achieve this I used the following procedure:

  1. Press Windows key + X
  2. Click Command Prompt (Admin)
  3. Type: slmgr.vbs -upk + ENTER

This will uninstall the product key from the computer and set it back to trial mode. The key is now available to be used on your new laptop/PC.

If you encounter any problems using the free key, try activating by telephone:

  1. Press Windows key + X
  2. Click Command Prompt (Admin)
  3. Type: slui.exe  4 + ENTER
  4. Select your ‘Country’ from the list.
  5. Choose the ‘Phone Activation’ option.
  6. Stay on the phone (do not select/press any options) and wait for a person to help you with activation.
  7. Explain your problem clearly to the support person.
