Symptoms

A small subset of Generation 2 Azure Virtual Machines (VMs) with Trusted Launch disabled, and Virtualization-Based Security (VBS) enforced via registry key might be unable to boot after installing this update.

To check if your virtual machine might be impacted:

1. Check if your VM is created as “Standard”.
2. Check the VM version by checking the registry key, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization, and confirming the CurrentVmVersion value is listed as 8.0.
3. Check if VBS is enabled. Open System Information (msinfo32.exe) and confirm that Virtualization-based security is running and that the Hyper-V role is not installed in the VM.

Workaround

This issue is addressed in KB5064489.

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.

1 This latest cumulative update includes updates for AI components. Even though the AI component updates are included in the update, the AI components are only applicable to Windows Copilot+ PCs and will not install on Windows PC or Windows Server.

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.
