Update 11/9/2018: This issue has been resolved. Near the end of the day yesterday, users were reporting the activation issue had been resolved. The user shouldn’t need to do anything other than going to Settings > Update & Security > Activation and you will see your version of Windows 10 Pro is genuine. In an article from Mary Jo Foley she notes an official statement from Microsoft exec Jeff Jones: We still don’t have an explanation on why the problem occurred in the first place. Here is the message from Microsoft Support: If you go to Settings > Update & Security > Activation you may see the following message about your license not being valid. 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
You can try to click on “Troubleshoot” link and Windows will try to detect any problems. And for some users, that’s all it takes to get the license squared away.
