Windows 8 Activation #FAIL

So I built my media server however the activation key on my purchased Windows 8 Pro Install discs wouldn’t allow me to activate it. Below is what you can do to bypass this and allow your legitimate¬†activation key to work.

Below is the error that was thrown even though I installed Windows 8 Pro directly from that disc.

Your key is an update only key… meaning it won’t allow a fresh install… unless you do the registry workaround from Windows 7.

  1. Open Run and type: “Regedit”
  2. Then located the following key:
    1. HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Setup/OOBE/
  3. Find the key named “MediaBootInstall”
  4. Double click and change it from a 1 to a 0.
  5. Open cmd as an administrator.
  6. Type the command “slmgr /rearm”
  7. You will get a window asking to restart your computer, restart it.
  8. Open Run and type “slui.exe 3” and a windows will appear allowing you to enter your key.
