Windows 11 servicing stack update (KB5058528) - 22621.5334 and 22631.5334​

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.


Applies to: All users

Symptom

Following the installation of the May 2025 Windows security update, some customers report that the update was not able to install on some Windows 11, version 22H2 and 23H2 devices. Affected devices might encounter the following recovery error:

Your PC/device needs to be repaired.
The operating system couldn't be loaded because a required file is missing or contains errors.
File: ACPI.sys
Error code: 0xc0000098

This issue has been observed on a small number of physical devices, but primarily on devices running in virtual environments, including:

• Azure Virtual Machines
• Azure Virtual Desktop
• On-premises virtual machines hosted on Citrix or Hyper-V

Home users of Windows using Home or Pro editions are unlikely to face this issue as virtual machines are mostly used in IT environments.

The ACPI.sys file (Advanced Configuration and Power Interface) is a critical system driver responsible for managing hardware resources and power states.

Note: There are also reports of this same error occurring with a different file name.

Workaround

We're 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.

1 This latest cumulative update includes update for AI components. Even though the AI component updates are included in the update, the AI components are only applicable to Windows Copilot+ PCs and will not install on Windows PC or Windows Server.

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.

File information

For a list of the files that are provided in this update, download the file information for cumulative update 5058405.

For a list of the files that are provided in the servicing stack update, download the file information for the SSU (KB5058528) - versions 22621.5334 and 22631.5334.
