June 26, 2025—KB5060826 (OS Builds 22621.5549 and 22631.5549) Preview

A gradual rollout distributes a release update over a period of time, rather than all at once. This means that users receive the updates at different times, and it might not be immediately available to all users. To see the status of this feature, go to Windows release health dashboard.

• [App defaults]

  • New!  We are rolling out some small changes in the European Economic Area (EEA) region for default browsers through the Set default button in Settings > Apps > Default apps:

    • Additional file and link types will be set for the new default browser, if it registers them.

    • The new default browser will be pinned to the Taskbar and Start menu unless you choose not to pin it by clearing the checkboxes.

    • There is now a separate one-click button for browsers to change your .pdf default, if the browser registers for the .pdf file type.

• [PC Migration] New!​​​​​​​  ​​​​​​​The PC-to-PC migration experience in Windows is starting to roll out. You’ll begin to see the landing and the pairing page in the Windows Backup app, giving you a first look at what’s coming. In the full experience, you’ll be able to transfer files and settings from an old PC to a new one during setup. Support for this feature during PC setup will arrive in a future update. The rollout is being introduced in phases to support a smooth experience.

• [Windows Share]​​​​​​​ ​​​​​​​New! When you share links or web content using the Windows share window, you will see a visual preview for that content.

• [Windows Setup] New! Admins can configure whether a new device gets critical updates during the out-of-box experience (OOBE).

This non-security update includes quality improvements. Key changes include:

• This build includes all the improvements in Windows 11, version 22H2.

• There are no additional issues documented for this release.

This non-security update includes quality improvements. The following summary outlines key issues addressed by the KB after you install it. Also, included are available new features. The bold text within the brackets indicates the item or area of the change.

• [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.

• [Authentication] Fixed: This update fixes an issue where domain-joined machines running Windows 11 22H2 or 23H2 couldn’t update their account passwords on Windows Server 2025 domain controllers, which led to trust relationship issues.

• [Country and Operator Settings Asset (COSA] Fixed: This update brings profiles up to date for certain mobile operators.

• [Display Kernel] Fixed: An issue that prevented Remote Desktop Protocol (RDP) connections until you restarted your device.

• [Network file sharing] Fixed: This update fixes an issue where workstations and servers might stop responding when connecting to resources located on Server Message Block (SMB) shares.

• [Performance] Fixed: This update addresses an issue that prevented the complete removal of unused language packs and Feature on Demand packages, which previously led to unnecessary storage use and longer Windows Update installation times.

• [Shell] Fixed: This update resolves an issue where kiosk devices might stop responding after being locked and unlocked by an administrator.

• [Windows Hello] Fixed: This update addresses an issue that prevented the automatic renewal of expiring certificates in Windows Hello for Business.

• [Windows Search]​​​​​​​ Fixed: Windows Search responds very slowly—the Search Box can take over 10 seconds to load before you can use it.

If you installed earlier updates, your device downloads and installs only the new updates contained in this package.

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.
