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. 

Customers can temporarily resolve the issue by updating permissions (ACLs) on the affected directories. Follow these steps:

1. Open PowerShell as an Administrator.

2. Update the permissions for C:\ProgramData\ssh and C:\ProgramData\ssh\logs to allow full control for SYSTEM and the Administrators group, while allowing read access for Authenticated Users. You can restrict read access to specific users or groups by modifying the permissions string if needed.

   Use the following commands to update the permissions:

   $directoryPath = "C:\ProgramData\ssh" $acl = Get-Acl -Path $directoryPath $sddlString = "O:BAD:PAI(A;OICI;FA;;;SY)(A;OICI;FA;;;BA)(A;OICI;0x1200a9;;;AU)" $securityDescriptor = New-Object System.Security.AccessControl.RawSecurityDescriptor $sddlString $acl.SetSecurityDescriptorSddlForm($securityDescriptor.GetSddlForm("All")) Set-Acl -Path $directoryPath -AclObject $acl

3. Repeat the above steps for C:\ProgramData\ssh\logs.

Microsoft is actively investigating the issue and will provide a resolution in an upcoming Windows update. Further communications will be provided when a resolution or additional workarounds are available.

Devices that have certain Citrix components installed might be unable to complete installation of the January 2025 Windows security update. This issue was observed on devices with Citrix Session Recording Agent (SRA) version 2411. The 2411 version of this application was released in December 2024.
 
Affected devices might initially download and apply the January 2025 Windows security update correctly, such as via the Windows Update page in Settings. However, when restarting the device to complete the update installation, an error message with text similar to “Something didn’t go as planned. No need to worry – undoing changes” appears. The device will then revert to the Windows updates previously present on the device. 
 
This issue likely affects a limited number of organizations as version 2411 of the SRA application is a new version. Home users are not expected to be affected by this issue. 

Citrix has documented this issue, including a workaround, which can be performed prior to installing the January 2025 Windows security update. For details, see Citrix’s documentation.

Microsoft is working with Citrix to address this issue and will update this documentation once a resolution is available. 
 

After installing this security update, you might experience issues with USB audio devices. You are more likely to experience this issue if you are using a USB 1.0 audio driver based DAC (Digital to Analog converter) in your audio setup. This issue might cause USB audio devices to stop working, preventing audio playback.

DACs (Digital-to-Analog Converters) are commonly used in scenarios where users need to improve the quality of their audio systems. A few scenarios where they are used are home audio systems, professional music studios and portable music players.

Resulting from this issue, the Device Manager might display the error ‘This device cannot start. (Code 10) Insufficient system resources exist to complete the API’.
