 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

Microsoft has shared its findings on the blurry text issue at 96 DPI, along with potential solutions with Google for further discussion. For additional support, users can report issues related to Noto CJK fonts through the official Google Noto Fonts GitHub repository.

Applies to: Enterprise customers and IT admins

Symptoms

After installing KB5055627, you might encounter issues with the Microsoft Print to PDF functionality. Specifically, the Microsoft Print to PDF printer might no longer appear under Settings > Bluetooth & devices > Printers & scanners. You might also notice that enabling the Printing-PrintToPDFServices-Feature returns error code 0x800f0922, which prevents the installation of the Microsoft Print to PDF printer driver located in C:\Windows\System32\DriverStore\FileRepository.

To address this, try enabling the Printing-PrintToPDFServices-Feature using one of the following options:

Option 1: Press Windows + R, type optional features, and enable Microsoft Print to PDF in the Windows Features dialog.

Option 2: Open PowerShell as Administrator and run the following commands:

  1. Disable-WindowsOptionalFeature -Online -FeatureName Printing-PrintToPDFServices-Features​​​​​​​

  2. Enable-WindowsOptionalFeature -Online -FeatureName Printing-PrintToPDFServices-Features

    Note: The final command might encounter an error with code 0x800f0922.

Workaround

This issue is addressed in KB5060829.

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.
