This 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 in this release.

This preview update contains fixes and quality improvements from KB5062552 (released July 8, 2025). 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.

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

  • [File systems]

    • Fixed: This update addresses an issue in the Resilient File System (ReFS) where using backup applications on large files could occasionally result in system memory becoming fully exhausted.

    • Fixed: An issue where searching for PDF files in a shared folder could return incorrect error messages—such as “No More Files” or “STATUS_NO_MORE_FILES.” These errors disrupted output to the virtual PDF printer and interfered with backup processes.

  • [Input (known issue)] 

    • Fixed: An issue when using the Microsoft Changjie IME (input method editor) for Traditional Chinese might cause problems such as not being able to form or select words, unresponsive spacebar or blank key, incorrect word output, or a broken candidate window display. This can occur after installing KB5062552.

      • Fixed: This update addresses an issue that affects Phonetic input methods, including the Hindi Phonetic Input keyboard and the Marathi Phonetic keyboard, which might not work correctly after installing KB5062552.

  • [Networking] Fixed: An issue where peripheral devices could take longer to work after resuming from hibernation on some devices with active cellular connections.

  • [Printer] Improved: Printer names now appear more clearly when using IPP Directed Discovery, making it easier to identify printers during setup.

  • [Stability issue] Fixed: This update addresses an issue observed in rare cases after installing the May 2025 security update and subsequent updates causing devices to experience stability issues. Some devices became unresponsive and stopped responding in specific scenarios.

  • [Taskbar] Fixed: This update addresses an issue where the taskbar icons for accessibility features are not appearing.

Available

Next Step

Included

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.
