The May Updates for Windows 11 and Windows 10 caused some services to crash

Earlier this week, Microsoft released monthly cumulative updates for all supported versions of Windows, which again turned out to be quite problematic. Microsoft has already acknowledged the issues and added a notice to that effect on the Windows Release Status page.

Company declares that updates KB5013943 (Windows 11 Build 22000.675) and KB5013942 (Windows 10 Builds 19043.1706, 19042.1706, and 19041.1706) cause client and server OS version authentication failures in services such as Network Policy Server (NPS), Routing and Remote access Service (RRAS), Radius, Extensible Authentication Protocol (EAP), and Protected Extensible Authentication Protocol (PEAP). This issue is related to how the domain controller handles the mapping of certificates to computer accounts.

Microsoft engineers are currently investigating the issue and preparing an appropriate fix. For now, administrators can get around the problem by manually mapping certificates to a computer account in Active Directory. Required instructions can be found in the documentation on the Microsoft website.

This issue does not affect client and server versions of Windows that are not controlled by a domain.
