Let's say I have one of those Windows 8.1 Pro PCs that have the product key embedded in the BIOS. When you install Windows 10 to this, it will activate using that Windows 8.1 BIOS key.
However let's say I had a reason to use my own genuine Windows 10 Home (not pro) product key. I can go to Settings > Activation > Change Product Key and use the Win 10 key and it will say activation was successful.
However, running this wmic path softwarelicensingservice get OA3xOriginalProductKey
shows the original Win 8.1 Pro embedded BIOS key even after a reboot. Also the System window shows the product key ending in -AAOEM which from my understanding means it is using the OEM embedded key.
I have tried completely reinstalling using the Win 10 ISO and their media creation tool. Windows 10 Home gets successfully installed and activates successfully, however always seemingly with the embedded BIOS product key and not the one I provided. However this may be just a misunderstanding on my part and I"m not 100% understanding that perhaps this is still being activated with my product key, but I can't see how I can tell. The "version" is successfully dowgraded from 8.1 PRO to 10 HOME by using the PID.txt method in the installation media.
Any ideas?
EDIT: This is unlike the suggested Possible Duplicate as in that thread, someone is trying to upgrade their overall edition, not downgrade. They are successfully activating but not with a new product key as I am trying to do.
