This was updated from windows 8 when it was free, never had a problem with it, not even when updating from a FX-8### rig to an Intel one.
Now i have changed the motherboard and CPU again i get this crap:
It never came with a license key, it was a straight upgrade free from windows 8.
when trouble shooting i get this.
When i click on changed hardware it just says 'again' you cann't activate windows on this device, no explication, just basically no... go away.
WTF?
