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

Applies to	Symptom	Workaround
All users	We’re aware of an issue where players on Arm devices are unable to download and play Roblox via the Microsoft Store on Windows.	Players on Arm devices can play Roblox by downloading the title directly from www.Roblox.com.
Enterprise users	After a fresh install or an In-place upgrade to Windows 11, version 24H2, you might face issues with connecting via DirectAccess. You might observe that the DirectAccess connection is not completing and remains in a ‘connecting’ state. Additionally, you can determine if you are affected by this issue by following the below steps: Open Windows PowerShell in administrator prompt. This can be accomplished by opening the Start menu and typing ‘powershell’ and selecting from the results on the right side of the start menu. Type the text ‘netsh interface httpstunnel show interface’ and press enter If your device is experiencing this issue, you’ll observe that the output includes the following text: Last Error Code : 0x57 Interface Status : failed to connect to the IPHTTPS server. Waiting to reconnect You are more likely to face this issue if your device is remotely connecting to a corporate intranet using DirectAccess. Home users of Windows using Home or Pro editions are unlikely to face this issue as DirectAccess is more commonly used in enterprise environments. Note: Enterprise customers that require DirectAccess are recommended to evaluate Always On VPN (AOVPN) until a fix becomes available.	This issue is addressed in KB5044384.
All users	Following the installation of the October 2024 security update, some customers report that the OpenSSH (Open Secure Shell) service fails to start, preventing SSH connections. The service fails with no detailed logging, and manual intervention is required to run the sshd.exe process.This issue is affecting both enterprise, IOT, and education customers, with a limited number of devices impacted. Microsoft is investigating whether consumer customers using Home or Pro editions of Windows are affected.	This issue is addressed in KB5052093.
