Hi JayLyle,
Thank you for posting your query on Microsoft Community.
As per the issue description, I understand that you are willing to know what “SettingSyncHost.exe” do.
“SettingSyncHost.exe” is the process that synchronizes your system settings with your other devices so that changing your wallpaper/color on one computer changes all your other computers. It also syncs your Internet Explorer, mail app, OneDrive,
Xbox and other useful apps settings.
We have a dedicated forum support for systems on domain issues, I would suggest you to post your query on Microsoft TechNet forum for this issue. There you can get more effective and appropriate
suggestions by experts familiar with this topic.
