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 a variety of issues, including fixes for File Explorer, fonts and display, graphics, performance and 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 an issue where certain GPU configurations were experiencing system errors related to dxgmms2.sys, resulting in the KERNEL_SECURITY_CHECK_FAILURE error.- 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, allowing evaluation of DoH for traffic between the server and its clients.- Adds support for random shuffling of resource records in DNS Server responses to help reduce scenarios where a single record becomes overloaded.
General Sentiment
The general sentiment around this update appears to be mixed. While it addresses several important security and quality issues, some users have reported experiencing performance degradation, especially in environments with heavy remote desktop usage. This seems to be related to compatibility issues between the update and third-party RDP tools like TSplus, which rely on customizations to the Remote Desktop Services stack. To mitigate the performance problems, users may need to either wait for compatibility updates from their third-party vendors or consider migrating to the native Remote Desktop Session Host architecture, which is officially supported and tested against these Windows updates. Uninstalling the update can restore performance, but leaves the system vulnerable to the security issues it was designed to address.Overall, the update appears to provide important security and quality improvements, but the impact on certain remote desktop configurations needs to be carefully evaluated before deployment.
Known Issues
- Windows Server Update Services (WSUS) does not display synchronization error details after installing KB5070881 or later updates. This functionality has been temporarily removed to address a Remote Code Execution Vulnerability (CVE-2025-59287).
