• [Audit] Fixed: An issue with auditing privilege use created too many security event logs. These logs filled up the system drive and prevented users from signing in.

Windows 11 servicing stack update (KB5061903) - 22621.5550 and 22631.5550​

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​

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.


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.
