In multiple countries, users are seeing their Windows 10 Pro Licenses suddenly downgraded to Home


A fresh Microsoft bug took several people by surprise today as they woke up to find their valid Windows 10 Pro license had suddenly downgraded to Windows 10 Home.

The deactivation and downgrade seems to have occurred in several countries, including the US, UK, Korea, and Japan.

It’s not affecting just users that had prior Windows 7 or Windows 8 Professional keys that upgraded to Windows 10 Pro, but also users with new computers running Windows 10 that upgraded to Windows 10 Pro.

Only Windows 10 Pro users are affected, Windows 10 Home is still working fine.

So, if you have Windows 10 Pro and received a notification saying your Windows is deactivated or that you need to install Windows 10 Home, don’t panic. Hopefully, the fix will come out soon.

[UPDATE 11-9-18]  A fix has been applied by Microsoft.  If you are experiencing this issue, click the Start menu, go to Settings (gear icon), Update & Security, Activation, then click “Troubleshoot”.  That should automatically re-activate Windows.  If it does not, Jeff Jones, Sr. Director, Microsoft says: “A limited number of customers experienced an activation issue that our engineers have now addressed.  Affected customers will see resolution over the next 24 hours as the solution is applied automatically.  In the meantime, they can continue to use Windows 10 Pro as usual.”
