Probability of successful installation and continued operation of the machine
Overview
This cumulative update for Windows Server 2025 (KB5075899), includes the latest security fixes and improvements, along with non-security updates from last month's optional preview release. It addresses several issues across File Explorer, Fonts & Display, Graphics, Performance & Reliability, and Networking.
General Purpose
The key improvements in this update include:- Fixes an issue where folder renaming with desktop.ini files in File Explorer isn't working correctly, causing custom folder names to not appear.- Updates the Chinese fonts to support the GB18030-2022A standard for improved character coverage and display.- Addresses a system error related to dxgmms2.sys that could cause the KERNEL_SECURITY_CHECK_FAILURE error on certain GPU configurations.- Disables the forwarded I/O feature in the NVMe stack by default to improve performance and reliability.- Introduces a public preview of DNS over HTTPS (DoH) support for the Windows DNS Server, along with the ability to randomly shuffle resource records in DNS Server responses to help reduce overloading of individual records.
General Sentiment
The general sentiment around this update seems mixed. While it includes several important fixes and improvements, the introduction of the DoH preview and the change to the NVMe stack have raised some concerns. Some users have reported performance issues, especially in environments with high concurrent user loads like remote desktop scenarios. There are also reports of compatibility issues with third-party tools and applications that may rely on the modified components.Overall, the update appears to be a necessary security and quality release, but caution is advised, especially for mission-critical systems or those with complex configurations. Thorough testing in a non-production environment is recommended before deploying this update widely.
Known Issues
- Windows Server Update Services (WSUS) does not display synchronization error details within its error reporting after installing KB5070881 or later updates. This functionality has been temporarily removed to address a separate Remote Code Execution Vulnerability, CVE-2025-59287.
