Windows 10: Windows 10 pro activation lost

One year ago I bought an Asus Notebook with preinstalled Windows 10 Home which I upgraded to Windows 10 Pro (upgrade bought in the Microsoft store). The activation of Windows 10 Pro worked with no problems.

After one year without any problems I now get the message "Activate Windows Go to Settings to activate Windows" in the lower right corner of the desktop.

When I go to Settings / Update & Security / Activation is says:

Edition: Windows 10 Pro

Activation: Windows is not activated

We can't activate Windows on this device because you don't have a valid digital license or product key....

Error code: 0x803F7001


ShowKeyPlus gives the following results:

Product Name: Windows 10 Pro

Version: 16299.726 (64-bit OS)

Product ID: 00330-80000-00000-AA663

Installed Key: VK7JG-NPHTM-C97JM-9MPGT-3V66T (which is the generic Windows 10 Pro key)

Original Key: xxxxx-xxxxx-xxxxx-xxxxx-xxxxx (a Windows 10 key, same as OEM Key)

Original Edition: Win 10 RTM Core OEMM

OEM Key: xxxxx-xxxxx-xxxxx-xxxxx-xxxxx (a Windows 10 key, same as Original Key)

OEM Edition: Win 10 RTM Core OEMM


I did not changed any hardware nor did I change or install any software except the quality and driver updates for Windows Version 1709.

The last Windows updates have been installed on November 8, 2018, a day before the activation problem showed up:


quality updates
- update for Adobe Flash Player for Windows 10 Version 1709 for x64-based Systems (KB4462930)
- 2018-10 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4462918)


driver updates
- Intel Corporation - SoftwareComponent - 4/16/2018 12:00:00 AM - 20.50.3
- Intel Corporation - Extension - 3/1/2018 12:00:00 AM - 1.0.0.5


other updates
- Windows Malicious Software Removal Tool x64 - October 2018 (KB890830)


I made a full system scan with Avira and Windows Defender. No malware has been found.

What could be the cause of the problem?

How to solve the problem?


Thanks!

Windows 10 Activation (Insider)

How long did you wait for activation?
When I re-installed with a fresh install... it took a few hours to sync and activate.
However, it did, finally, activate.
