Microsoft support announced that it is aware of the problem and is working to fix the error.
Users found an error Microsoft activation server.
On some computers running Windows 10 Pro, the operating system reported that Windows 10 Pro was disabled and prompted users to install Windows 10 Home.
During the diagnostic, a license conflict has been detected as installing Windows 10 Pro attempts to work with the Windows 10 Home license. In this case, the user must either change the operating system to the original version or purchase the Pro version key. However, trying to buy the Windows 10 Pro Key in the app store does not resolve the issue.
Microsoft support said that they are aware of this problem and are working to detect an error associated with an activation server for some kind of failure. The company acknowledged that some systems with Windows 10 Pro and Windows 10 Enterprise did not recognize the previously activated license.
This problem was encountered by users in Russia, Japan, the United States, Korea and other countries. Microsoft has promised that the problem will be resolved within 24 hours, and computers with Windows 10 Pro will automatically receive fixes.
Recall that Microsoft canceled the latest Windows update after deleting user files.
