Windows 10: Suddenly Win 10 Pro not activated.

I had a custom computer built commercially for me 1 1/2 years ago with Win 10 Pro installed. I have been using it steadily since with no problem. All of a sudden I am getting indication that my Win 10 is not activated. Tried to locate a Product Key through Admin wmic path, but unable to locate it. Why is this suddenly happening, and what's going on?

Windows 10 Pro suddenly becomes not activated after upgrading to (10.0.17763.55)

(message on 8 Nov 2018) My Windows 10 Pro was upgraded from Win 8 Pro some years ago. It had been activated and signed into with a Microsoft account. I can see my Windows 10 Pro in the device list of my Microsoft account.

Suddenly I found that my Windows is now not activated with error code: 0xC004C003. Activation Troubleshooting said "We found a Windows 10 Home digital license for this device running Windows 10 Pro." It happened after a few days I installed Windows Update
for (10.0.17763.55)!

Anyone knows what is wrong?

(status updated on 9 Nov 2018) - Wow. After a day, my Windows activation really comes back. Waiting is the best solution for that

 

MSDN Win 10 Pro Activation Issues

Here is a Microsoft paper on activation issues.

I suggest that you use the TechNet forums for this particular issue. This forum is consumer-oriented (Win 10 Home, Pro). TechNet is IT oriented (Win 10, Pro, Enterprise, MSDN, Server 2012-R2, etc.).
