Licenza Windows 10 OEM

So, you never ran the powershell code? If not, you need to run it.

The PowerShell code would specifically read from the motherboard to confirm if the OEM key is embedded in the motherboard. ShowKey Plus will show the key type and key, but it will not necessarily confirm if the key is embedded in the motherboard or manually entered.

hello

I was sure that I run the code Powershell, but in fact (I just rechecked now) the command yields no response. The (presumed) OEM code was supplied to me by the vendor (this is a refurbished PC). I used that code manually to update the activation code, apparently without problems. ShowKeyPlus says that (I translate from italian) there is also an "OEM Windows 7 code marker embedded in BIOS".

That is because (I imagine) the PC was supplied by the manufacturer with Win 7 installed? In that case the Win 10 OEM key is not really embedded in the MB. Right?

Correct, this means the key is never in the hardware itself, it was manually entered, so it will NOT be picked up automatically. Only key embedded int he hardware/motherboard is picked up automatically. This is exactly why I wanted you to run that powershell command, because it checks the hardware, not just what type of key you have. I hope that makes sense.

Just to resume:

I have three identical HP desktops bought as refurbished PCs.

All are running Windows 10 Pro

Two of them have an activation key in the BIOS as checked with Powershell

However these keys are for Windows 7 and for Windows 8.1

The third one has no key in the BIOS,

All three were supplied with Windows 10 activated by an OEM key by the vendor, that key obviously not sitting in the BIOS.
