Download Windows 10 64-bit ISO Latest Update: Understanding the Recent Issue

Microsoft has recently released an update that affects some users' ability to save and copy files using certain applications on their Windows devices. The issue, which was first reported with KB5023773 or later updates, is likely to occur when using 32-bit apps on 64-bit Windows systems with Trellix Endpoint Security Agent version earlier than 35.31.25.

The problem appears to be more prevalent in enterprise and commercial settings where extended file attributes are used by certain security software. In such cases, users may experience intermittent issues saving, copying, or attaching files using large address aware 32-bit apps that utilize the CopyFile API.

Interestingly, this issue is not likely to affect consumers who use Windows devices at home. The affected applications include Microsoft Outlook and other Microsoft Office programs, which might fail to open after installing KB5027215 or later updates on Windows devices with specific antivirus, antimalware, or security software installed.

When attempting to launch an affected app, the Event Log may display an access violation error message stating 'module is unknown.' This issue only occurs when using 32-bit apps on 64-bit Windows systems with outdated versions of Trellix Endpoint Security Agent.

Fortunately, Trellix has resolved this issue in their Endpoint Security Agent (HX) version 35.31.25 and later. Users experiencing this problem are advised to contact the customer support team of their security software provider if they are using other commercial or enterprise security solutions.

In summary, users who encounter difficulties saving and copying files using certain apps on their Windows devices should ensure that their Trellix Endpoint Security Agent is updated to version 35.31.25 or later to resolve the issue. If you're a consumer, it's unlikely that you'll be affected by this problem, but if you do experience issues, you can reach out to Microsoft support for assistance.
