New Activation Bug Downgrades Window 10 Pro License To Window 10 Home

Microsoft is fixing a bug that has been causing Windows 10 Pro licenses in many devices downgraded to Windows 10 Home which triggered the notification asking users to activate their copies of Windows 10.

"All of a sudden after years of having this key, which was from Windows 8 Pro, then migrated to Windows 10 for free, I got a notification saying my key is Windows 10 Home version and that I need to install it. wtf is going on?" a comment on a Reddit thread relating to the bug.

Another user that was experiencing the same problem commented: "Just happened to me. I had a physical Windows 8.1 Pro key and I activated/upgraded it to Windows 10 Pro like years ago."

Microsoft later confirmed that its activation server is having an issue and they are fixing it. Sr. Director at Microsoft, Jeff Jones, specifically said that they are working to restore Window 10 Pro activations for users who were affected by the bug. Therefore, users who were affected don’t have to worried about their licenses being invalid.

A Window 10 Pro's user - DanielRandy reported the issue on a forum of Microsoft and got a response from a Microsoft staff saying that Microsoft has just released announcement relating to the Windows 10 Pro issue claiming that the issues were mostly happening in Korea, America, Japan, and many more countries. Many users who reported the issue in the same platform also received similar responses from Microsoft staffs.

A Twitter user, who also reported the bug, got a response from @MicrosoftHelps in Twitter saying that there are currently no known issues relating to the deactivation of license.

Since then, the @MicrosoftHelps requested users who were affected to send them more details via direct messaging. It may at least suggest that Microsoft is trying to investigate the issue.
