Hello! So my old motherboard just died on me so I needed to get another one(everything else remained the same). Now the Windows is working, but it isn't activated. I tried putting my old key in, but it is already used by other device(old mobo I think).
Is there any possible way to reactivate my Windows with my current key. No my account wasn't linked to MS account. I don't mind is it gets unactivated on my old motherboard since it is already in trash. I will not buy a new key again, because I just did buy that Win like a month ago and it was over 100€.
 
Got it working via the chat. Technician used remote desktop and entered some codes. He just wanted some proof that i bought new mobo. Everything works perfectly fine and Microsoft has amazing support.
