General Purpose

KB5060999 Purpose

The primary purpose of KB5060999 is to address security vulnerabilities in Windows 11 versions 22H2 and 23H2. This update is part of Microsoft's June 2025 Patch Tuesday release and focuses on maintaining system security and stability.

The update resolves a significant graphics support issue that was preventing some users from successfully connecting via Remote Desktop. Users experiencing errors such as "The Remote Desktop Services session has ended" or "A remote desktop connection cannot be established" should find these problems resolved after installing this update.

KB5060999 also includes all improvements from the previous update KB5058502 released in May 2025. Additionally, it incorporates a servicing stack update (KB5058546) which enhances the component responsible for installing Windows updates, ensuring more robust and reliable update installations in the future.

General Sentiment

KB5060999 General Sentiment

The general sentiment toward KB5060999 appears to be cautiously positive, though with some concerns. The update addresses important security vulnerabilities and fixes a notable Remote Desktop connection issue that had been affecting users, which has been well-received by the community.

However, there are some concerns regarding the update process itself. Some users have reported installation failures with error code 0x80040154, as documented in Microsoft's Q&A forum. This suggests that while the update itself may be stable, deployment challenges exist for a subset of users. The error appears to be related to deeper system issues rather than the update itself, as the resolution often involves more complex troubleshooting steps beyond standard update procedures.

It's worth noting that the update metadata timestamp issue (showing June 20 instead of the actual release date of June 10) may cause confusion for organizations using quality update deferral policies, potentially delaying the update's deployment in enterprise environments. While this doesn't affect the update's quality, it does impact deployment timing for organizations with specific update management policies.

Known Issues

KB5060999 Known Issues

• Noto fonts issue: Blurry or unclear CJK (Chinese, Japanese, Korean) text when displayed at 96 DPI (100% scaling) in Chromium-based browsers such as Microsoft Edge and Google Chrome. The issue stems from the March 2025 Preview Update's introduction of Noto fonts for CJK languages. Increasing display scaling improves clarity.

• Update delay with deferral policies: Some devices in environments where IT administrators use quality update (QU) deferral policies might experience delays in receiving the June 2025 Windows security update. Although released on June 10, 2025, the update metadata timestamp shows June 20, 2025, potentially causing devices with configured deferral periods to receive the update later than expected.
