I had a Windows 7 with genuine OEM key. That was like 10 years ago, so I no longer have the key. When MS offered a free upgrade to Win10 I did that and migrated to "digital license". Recently I've upgraded my PC and replaced MB and CPU.
The problem is that I cannot reactivate it again following "Hardware was changed" steps on MS website. Activation Wizard is giving me an error code 0xC004F211. I've even tried calling MS phone activation line, but that was an exercise in frustration, as the guy barely spoke English, and my German is bad. He insisted that I have do find my old Win 7 product key and use it for activation. That sounds like complete bonkers, I'm 99% sure it's not going to work even if I still had it. Do I have any other options to activate other than buying a new key ?
