Windows 8 Activation Key Not Accepted

I was having trouble activating a new Windows 8 Pro install and stumbled on this advice for Windows 7.  It worked great for Win8pro 🙂

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

  You need to open a run box and type: “Regedit”

  Then located this key:

  HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Setup/OOBE/

  And find the one called “MediaBootInstall”.

  Double click that and change it from a 1 to a 0.

  Then open up cmd as an administrator

  Type the command “slmgr /rearm”

  You will get a restart your computer messge.

  Restart

  Then when your computer restarts you need to open a run box again and type “slui.exe 3” and it will allow you to enter your product key and activate 🙂
