Windows 7 OEM Home Premium Won't Activate On 2nd Home Computer...

post #1 of 7
Thread Starter 
I'm trying to activate my Windows 7 OEM home premium on a second computer and I get this message:

Error Code OxC004C756

I called microsoft, they said my key is invalid, then tried to make me do the phone activation which also failed, at the end of which i stayed on the phone on hold for over 40 minutes and hung up.

Any ideas?

They must let you activate it on another one?

I had that on my xp disc.I was told by my computer buddies at work that there was a remote chance that someone actually guess the number corrctly and used it.So therfore,the number is useless.

If that's true,then don't reformat your first computer.

Fixed.

Your key has already been used on another motherboard. OEM keys are tied to the mobo's hardware signature.

However if for some reason the motherboard on that OEM PC had to be replaced you would just need to tell microsoft that the motherboard had to be replaced and they will walk you through activation. Just an FYI.
