KB5063060 (OS Build 26100.4351) Out-of-Band Update for Windows 11 24H2 - June 11, 2025
Out-of-band cumulative update for Windows 11 version 24H2 (OS Build 26100.4351) released June 11, 2025, fixing an Easy Anti-Cheat incompatibility that caused unexpected restarts.
Summary
KB5063060 is an out-of-band (OOB) cumulative update for Windows 11 version 24H2, producing OS Build 26100.4351. Released on June 11, 2025, it includes all security fixes from the June 10, 2025 security update (KB506842) plus a targeted fix for an Easy Anti-Cheat incompatibility. See the Microsoft Support page for full details.
Highlights
- Resolves an incompatibility between Windows and the Easy Anti-Cheat service that could cause devices to restart unexpectedly when launching certain multiplayer games.
Improvements and fixes
- Easy Anti-Cheat compatibility fix: The update resolves a conflict where Windows could restart without warning when a user opened a game that relies on the Easy Anti-Cheat service. Easy Anti-Cheat installs automatically alongside certain titles to improve security and deter cheating in online multiplayer games. Microsoft notes that most users were unlikely to encounter this problem because the earlier update that introduced the conflict (KB506842) was not offered to devices that already had Easy Anti-Cheat installed.
- Includes June 10, 2025 security content: As a cumulative package, KB5063060 carries all security fixes and quality improvements from KB506842, so devices that have not yet installed that update will receive that content as well.
- Servicing stack update bundled (KB5059502, build 26100.4193): Microsoft has combined the latest servicing stack update (SSU) for Windows 11 24H2 into this package. The SSU improves the reliability of the component responsible for installing Windows updates.
Known issues
Blurry CJK text in Chromium-based browsers (Noto fonts)
Symptom: Some users see blurry or unclear Chinese, Japanese, and Korean (CJK) text when browsers such as Microsoft Edge or Google Chrome display content at 96 DPI (100% scaling). The March 2025 Preview Update introduced Noto fonts as CJK fallback fonts in collaboration with Google. At 96 DPI, limited pixel density can reduce the sharpness and alignment of CJK characters. Increasing display scaling improves text clarity.
Workaround: Microsoft has shared its findings and potential solutions with Google for further review. Users can report Noto CJK font issues through the official Google Noto Fonts GitHub repository. No Windows-side fix is documented for this issue at the time of writing.
Microsoft Print to PDF printer missing or fails to install
Symptom: After installing KB5055627, the Microsoft Print to PDF printer may disappear from Settings - Bluetooth & devices - Printers & scanners. Attempting to re-enable the Printing-PrintToPDFServices-Feature may return error code 0x800f0922, blocking reinstallation of the driver from C:\Windows\System32\DriverStore\FileRepository. As a temporary measure, the feature can be toggled via the Windows Features dialog (Windows + R, then type "optional features") or by running Disable-WindowsOptionalFeature followed by Enable-WindowsOptionalFeature in an elevated PowerShell session, though the enable command may still return error 0x800f0922.
Workaround: This issue is resolved in KB5060829.
How to get this update
Before installing, be aware that Microsoft bundles the latest SSU (KB5059502, version 26100.4193) with this cumulative update. Because the SSU cannot be removed after installation, running the standalone installer (wusa.exe) with the /uninstall switch will not work for the combined package. To remove only the LCU component, use the DISM /Remove-Package command with the LCU package name as the argument; use DISM /online /get-packages to find the correct name.
The update is available through the following channels:
- Windows Update / Microsoft Update - Downloads and installs automatically on devices that have Easy Anti-Cheat installed and on devices that have not yet installed KB506842.
- Windows Update for Business - Available through standard policy-based deployment.
- Microsoft Update Catalog - Available for manual download and deployment.
- Windows Server Update Services (WSUS) - Available for enterprise environments managing updates centrally.
File lists for both the cumulative update (KB5063060) and the SSU (KB5059502, version 26100.4193) are available for download from the Microsoft Support page.
Frequently asked questions
Why was this update released out-of-band rather than on Patch Tuesday?
Microsoft issues out-of-band updates outside the regular monthly schedule when a specific, time-sensitive problem needs an immediate fix. In this case, a compatibility conflict between the June 10 security update and the Easy Anti-Cheat service required a prompt resolution to prevent unexpected restarts on gaming devices, so Microsoft did not wait until the next monthly release cycle.
Do I need to install KB506842 separately before applying KB5063060?
No. KB5063060 is cumulative and already contains all security fixes and improvements from KB506842. Devices that skipped KB506842 will receive that content automatically when KB5063060 installs, so there is no need to apply the earlier update first.
Will this update install automatically on my device?
Yes, for most affected devices. Microsoft has configured KB5063060 to download and install automatically via Windows Update and Microsoft Update specifically on devices that have Easy Anti-Cheat installed and on devices that have not yet received KB506842. Devices that already installed KB506842 without issues may still receive the update through normal update channels.
Can I uninstall this update if something goes wrong?
Because this update bundles the SSU with the LCU, you cannot uninstall the entire combined package using wusa.exe with /uninstall. However, you can remove the LCU portion using the DISM /Remove-Package command. The SSU component (KB5059502) remains on the system permanently once installed, which is standard behavior for all servicing stack updates.
