Some Windows 10 Pro licenses are reportedly getting deactivated to Windows 10 Home
Several users have taken to Reddit to report a mysterious deactivation of their Windows 10 Pro license. They were being prompted that the existing license is for Windows 10 Home and that a Pro license can be ordered from the Store. Thing is, going to the Store apparently has no effect. The issue seems to mostly affect users who have migrated their Windows 7 or Windows 8.x Pro licenses to Windows 10. However, several Insiders have also reported of similar deactivations indicating that this could be a problem at Microsoft's end.
This sudden license change is not just from Pro to Home. A Reddit user said that upon restarting the PC, the license got converted to Windows 10 Enterprise for Virtual Desktops so clearly there's something wrong with Microsoft's activation servers. This issue seems to affect those running even earlier Windows 10 versions as well.
Thankfully, Microsoft is aware of the problem and said that their engineers are on it. Microsoft support chat seems to have told a customer that, "Customer will be notified when the issue is resolved". The company has also released a statement on the Microsoft Answers forum that reads,
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."
So, in the event your license got deactivated on its own, just leave it as is and your PC should automatically get activated as soon as Microsoft fixes the activation server issue. If needed, you can try your luck with Microsoft Support to see if they can issue a replacement Pro key but it shouldn't take long before Microsoft corrects the error.
