Improvements
This Out-of-band (OOB) update includes quality improvements. This update is cumulative and includes security fixes and improvements from the June 10, 2025, security update (KB506842), in addition to the following:
-
[Fix for incompatibility issue with Easy Anti-Cheat] This update addresses an incompatibility issue where Windows might restart unexpectedly when opening games that use the Easy Anti-Cheat service. Easy Anti-Cheat automatically installs with certain games to enhance security and prevent cheating in multiplayer online PC games.
Note: Windows users likely didn't experience this issue because the update that led to the incompatibility issue (KB506842) was not offered to devices with Easy Anti-Cheat installed.
This OOB update downloads and installs automatically from Windows Update and Microsoft Update on devices with Easy Anti-Cheat installed and on devices that have not installed KB506842 yet.
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.
How to get this 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.
