KB5062560: Overview with user sentiment and feedback

Overview

KB5062560 is a security update released for Windows 10 version 1607 and Windows Server 2016. This update includes important security hardening changes to the Microsoft RPC Netlogon protocol and addresses previously known stability issues. The update is part of the July 2025 security updates and builds upon fixes from the June 2025 update (KB5061010).

General Purpose

The primary purpose of this update is to implement security improvements and fix stability issues. It includes a significant security hardening change to the Microsoft RPC Netlogon protocol that tightens access checks for remote procedure call (RPC) requests. After installation, Active Directory domain controllers will no longer allow anonymous clients to invoke certain RPC requests through the Netlogon RPC server, particularly those related to domain controller location. The update also addresses a DHCP Server service issue where the service might intermittently stop responding and affect IP renewal for clients. Additionally, it resolves stability issues observed in rare cases after installing the May 2025 security update that caused some devices to become unresponsive.

General Sentiment

The general sentiment towards this update appears cautiously positive. The security hardening changes are seen as necessary improvements, particularly for enterprise environments using Active Directory domain controllers. However, there are some concerns about potential impacts on file and print service software, specifically for organizations using Samba. The update requires careful consideration for environments using these services, and administrators are advised to review the Samba release notes for compatibility information.

Known Issues

• DHCP Server service might intermittently stop responding and affect IP renewal for clients (Fixed in this update)
• Some file and print service software, including Samba, may be affected by the Netlogon protocol changes
• Previous stability issues causing devices to become unresponsive in specific scenarios (Fixed in this update)
