Microsoft Bug is Deactivating Windows 10 Pro Licenses and Downgrading to Home


Microsoft

A bug in what appears to be the Microsoft Windows activation service is causing Windows 10 Pro licenses to be downgraded to Windows 10 Home and then stating that Windows is not activated.

This bug appears to be widespread with many users reporting that Windows is stating that their license is not activated and prompting the user to troubleshoot the problems.

Windows 10 Pro not activated

We can't activate Windows on this device because you don't have a valid digital license of product key. If you think you do have a valid license or key, select Troubleshoot below. Error code: 0xC004C003
If you're having problems with activation, select Troubleshoot to try to fix the problem.

When users perform the Troubleshoot option, Windows is stating that “We found a Windows 10 Home digital license for this device running Windows 10 Pro.”

According to posts about this bug on Reddit and the Microsoft forums, someone had contacted Microsoft via their support chat and was told that Microsoft is aware and are working on the bug. 

“Microsoft has just released an Emerging issue announcement about current activation issue related to Pro edition recently. This happens in Japan, Korea, American and many other countries.I am very sorry to inform you that there is a temporary issue with Microsoft’s activation server at the moment and some customers might experience this issue where Windows is displayed as not activated. 
Our engineers are working tirelessly to resolve this issue and it is expected to be corrected within one to two business days “

I personally have contacted the Microsoft support chat and they had no idea what was going on.  We are awaiting more information from the Microsoft press contact, but had not heard back at the time of this publication.

This is a developing story …
