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

I did not change 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:
