A Moxie customer has discovered a recent update to Windows - KB5031356 – results in a dialog box appearing on player PCs, as shown below: 

Microsoft does not appear to have a policy-level method for preventing this dialog from appearing, which means manual intervention with a keyboard is required at each player where this dialog appears.   

We have opened a support ticket with Microsoft asking for guidance. 

In the meantime, we recommend that you do not update your Windows versions on your player PCs if manual intervention would not be practical.
