Windows 11 servicing stack update (KB5059502)- 26100.4193

This update makes quality improvements to the servicing stack, which is the component that installs Windows updates. Servicing stack updates (SSU) ensure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates. To learn more about SSUs, see Simplifying on-premises deployment of servicing stack updates.

Known issues in this update

Applies to: All users

Symptom

There are reports of 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 March 2025 Preview Update introduced Noto fonts in collaboration with Google, for CJK languages as fallbacks to improve text rendering when websites or apps don’t specify appropriate fonts. The issue is due to limited pixel density at 96 DPI, which can reduce the clarity and alignment of CJK characters. Increasing the display scaling improves clarity by enhancing text rendering.

Workaround

As a temporary workaround, increase your display scaling to 125% or 150% to improve text clarity. For more information, see Change your screen resolution and layout in Windows.

We are investigating this issue and will provide more information when it is available.

Symptoms

Some devices in environments where IT admis use quality update (QU) deferral policies might experience delays in receiving the June 2025 Windows security update. Although the update was released on June 10, 2025, its update metadata timestamp reflects a date of June 20, 2025. This discrepancy might cause devices with configured deferral periods to receive the update later than expected.

Workaround

To accelerate deployment of the June 2025 updates, admins can take one of the following actions:

  • Create an expedite policy to bypass deferral settings and deliver the update immediately if the organization is using Windows Autopatch.

  • Adjust deployment rings or deferral configurations to reduce the delay window for affected devices.

This delay issue affects only the timing of update availability for organizations using QU deferral policies and doesn't impact the quality or applicability of the update. We will not change the metadata value from the current June 20, 2025, value. This workaround is the final resolution we will provide for this issue.

How to get this update

Before you install this update

Microsoft combines the latest servicing stack update (SSU) for your operating system with the latest cumulative update (LCU). For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions

Install this update

To install this update, use one of the following Windows and Microsoft release channels.

Available

Next Step

Included

This update downloads and installs automatically from Windows Update and Microsoft Update.

If you want to remove the LCU

To remove the LCU after installing the combined SSU and LCU package, use the DISM/Remove-Package command line option with the LCU package name as the argument. You can find the package name by using this command: DISM /online /get-packages.

Running Windows Update Standalone Installer (wusa.exe) with the /uninstall switch on the combined package will not work because the combined package contains the SSU. You cannot remove the SSU from the system after installation.
