No PC will ever have an OEM key for Enterprise. Plus the showkey screen shot you posted shows your OEM key is for 8.1 Pro.
How did you upgrade from Windows 8.1 to Windows 10? Where did you buy this laptop from? It sounds like your laptop had Enterprise installed by an organization, and then sold to you as is. If so it may not have a Digital License for Windows 10 If so you need to install 10 Pro and hope it activates with your Windows 8.1 OEM key. I would write that key down now so you have it. The current ISO's for the 1703 CU did not auto read my laptops OEM embedded key. You may have to enter it manually.

 

Where did you get your install media (ISO) from?

 

Which is unusual because mine do read the OEM embedded key.

 

Windows 8 or 8.1 keys? Mine is a Windows 8.0 Core key. My MSDN as well as the MCT ISO ignored it? If it had happened only once I'd just take it as a glitch, I did several clean installs and it was ignored each time. I actually did a second install just to verify it wasn't a one time glitch.

 

Yes, Windows 8 keys. It read the Windows 8 Core key in UEFI, installed Windows 10 Home without asking for a product key or which version I wanted and activated. I then had to upgrade the Windows 10 Home to Pro by changing the product key to the generic Windows 10 Pro product key which then also activated based on a digital license for Pro. Just like previous versions.

 

OK, my key must be being read, but rejected as invalid or something?

That is not Microsoft. We recommend that people only download Windows ISO files directly from Microsoft, not third part websites like that one. You don't know what they might have inserted into the ISO file before you download it.

That also explains how you managed to obtain an Enterprise version of Windows 10 that likely violates the EULA (License Agreement) for you to activate and run - if the EULA applies in Thailand.

 

It's a little confusing. You state your key is a Windows 10 OEM Enterprise key (which doesn't exist), but ShowKey says it's an 8.1 Professional key. Are you currently running Windows 10 Enterprise? How did that get installed?

 

Hey mate, *Smile

In this case, the Installed key in ShowKeyPlus is for the currently installed Windows 10 Enterprise.

The OEM Key in ShowKeyPlus is just the key embedded in the UEFI firmware chip on the motherboard for the OEM Windows 8.1 that originally came preinstalled on the tablet.

Shawn, I think Mystere is wondering how did it activate...

NPPR9-FWDCX-D2C8J-H872K-2YT43 is a published GVLK that can only be activated with a KMS server.

 

Well, I was trying to get to the bottom of what the OP thinks is happening with his machine. Of course I understand what the situation is, I just want to know if the OP knows how it got to this state.

 

Running :
slmgr /dlv

would solve the mystery.
