This security update includes improvements that were a part of update KB5026446 (released May 24, 2023). When you install this KB:

This update addresses a known issue that affects 32-bit apps that are large address aware and use the CopyFile API. You might have issues when you save, copy, or attach files. If you use some commercial or enterprise security software that uses extended file attributes, this issue will likely affect you. For Microsoft Office apps, this issue only affects the 32-bit versions. You might receive the error, "Document not saved." 

This update addresses a compatibility issue. The issue occurs because of unsupported use of the registry.

This update addresses an issue that affects the Windows Kernel. This issue is related to CVE-2023-32019. To learn more, see KB5028407.

If you installed earlier updates, only the new updates contained in this package will be downloaded and installed on your device.

For more information about security vulnerabilities, please refer to the Security Update Guide website and the June 2023 Security Updates.

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.

IT admins

Using provisioning packages on Windows 11, version 22H2 (also called Windows 11 2022 Update) might not work as expected. Windows might only be partially configured, and the Out Of Box Experience might not finish or might restart unexpectedly. Provisioning packages are .PPKG files which are used to help configure new devices for use on business or school networks. Provisioning packages which are applied during initial setup are most likely to be impacted by this issue. For more information on provisioning packages, please see Provisioning packages for Windows.

Note Provisioning Windows devices using Windows Autopilot is not affected by this issue.

Windows devices used by consumers in their home or small offices are not likely to be affected by this issue.

If you can provision the Windows device before upgrading to Windows 11, version 22H2, this will prevent the issue.

We are presently investigating and will provide an update in an upcoming release.

Before installing 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.

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.
