Microsoft is working to fix the error, due to which after installing the KB4497935 update released in May 2019, users may experience problems starting or rebooting devices with MIT Kerberos.
The problem affects Windows 10 (versions 1703, 1709, 1803, 1809 and 1903), Windows 10 Enterprise LTSC 2019, as well as Windows Server (versions 1709, 1803, 1809, 1903), Windows Server 2016 and Windows Server 2019.“Domain-connected devices configured to use MIT Kerberos may not start or continue to reboot after installing the KB4497935 update. The problem affects both domain controllers and domain members”, – says message on the Microsoft technical support site.
It is expected that a patch fixing this problem will be released in mid-August this year, but currently the company recommends to postpone installing the KB4497935 update.
Kerberos is a network authentication protocol that offers a mechanism for mutual authentication of the client and server before establishing a connection between them. Protocol takes into account the fact that the initial exchange of information between the client and the server occurs in an unprotected environment, and transmitted packets can be intercepted and modified.

As well, Microsoft warned about blocking the installation of the new version of Windows 10 and Windows Server (1903) on some devices with Intel Rapid Storage Technology (Intel RST) drivers. According to the developers, this decision was made due to compatibility issues.
The problem concerns versions of Intel RST from 15.1.0.1002 to 15.5.2.1053. Devices based on newer versions (from 15.5.2.1054) may not block May updates.
“Intel and Microsoft have discovered compatibility issues with some versions of Intel Rapid Storage Technology (Intel RST) drivers and the May updates of Windows 10″, – explains Microsoft.
