Windows 11, version 22H2​

This security update includes improvements that were a part of update KB5040527 (released July 23, 2024). Below is a summary of the key issues that this update addresses when you install this KB. If there are new features, it lists them as well. The bold text within the brackets indicates the item or area of the change we are documenting.
  • [BitLocker (known issue)] A BitLocker recovery screen shows when you start up your device. This occurs after you install the July 9, 2024, update. This issue is more likely to occur if device encryption is on. Go to Settings > Privacy & Security > Device encryption. To unlock your drive, Windows might ask you to enter the recovery key from your Microsoft account.
  • [Lock screen] This update addresses CVE-2024-38143. Because of this, the “Use my windows user account” check box is not available on the lock screen to connect to Wi-Fi.
  • [NetJoinLegacyAccountReuse] This update removes this registry key. For more information refer to KB5020276—Netjoin: Domain join hardening changes.
  • [Secure Boot Advanced Targeting (SBAT) and Linux Extensible Firmware Interface (EFI)] This update applies SBAT to systems that run Windows. This stops vulnerable Linux EFI (Shim bootloaders) from running. This SBAT update will not apply to systems that dual-boot Windows and Linux. After the SBAT update is applied, older Linux ISO images might not boot. If this occurs, work with your Linux vendor to get an updated ISO image.
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 August 2024 Security Updates.

Windows 11 servicing stack update (KB5041584) - 22621.4027 and 22631.4027​

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.

Known issues in this update

Microsoft is not currently aware of any issues with this update.


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.

AvailableNext Step
Yes (Windows Update)None. This update will be downloaded and installed automatically from Windows Update and Microsoft Update.
Yes (MSU)To get the standalone package for this update, go to the Microsoft Update Catalog website.

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 5041585.

For a list of the files that are provided in the servicing stack update, download the file information for the SSU (KB5041584) - versions 22621.4027 and 22631.4027.

This is really silly, I liked the old Control Panel better than the complicated settings app.
As usual, MS seems to be going backward, this is sure not an improvement. 😂😝🤬

Still there for now.
But why are they planning to eliminate it? 😵‍💫🤷‍♂️
They are talking about it for many years, since W8, it will probably take even longer to finish transition if ever.

They keep breaking things as they add new useless experimental features.
Now with Build 27686, Windows Image Backup is broken. 😝😵‍💫
