  1. Run slui 4
  2. This will bring up phone activation screen.
  3. Go here
  4. Follow the prompts on the page
  5. When asked how many computers you have activated this key on, say 1.
  6. Plug in the installation id into the appropriate boxes
  7. Click Next on the activations screen
  8. Thype im the confirmation id into the appropriate boxes

This should force activate the OEM key.
