Windows 8 (upgrade) can't activate and reactivate on a new machine.
Windows 8 (upgrade) kan niet activeren na een schone installatie. Opnieuw activeren op een nieuwe computer.
our 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.
If this is not working, try activating it true the phone.
