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

As ZDNet reports, some users of Windows 10 Pro and Enterprise yesterday started having a "non-activated software" message pop up on their desktop. "In the meantime, they can continue to use Windows 10 Pro as usual", Microsoft Senior Director Jeff Jones told ZDNet late last night. However, several Insiders have also reported of similar deactivations indicating that this could be a problem at Microsoft's end.

The only nice thing about the Pro Upgrade license is that they are supposed to be transferable to a different device once the device that the Pro Upgrade is installed on has had the OS downgraded back to the home version. 'Users may receive the following notification: "Error: you are running Windows 10 Pro, but you have valid digital license for Windows 10 Home", or one of the following error codes: 0X803F8001, 0xC004C003.

Microsoft is aware of the problem, and advises users to ignore the message from Windows Activation and to wait for a fix.

Hours later, confirmation from Microsoft rolled in and impacted users were told that the license problem is the result of a server issue.
