Network Not Showing in Folder Tree

I just upgraded to Win 10 (for the second time - the first time was a disaster and had to be undone). The folder tree in 11.18 does not have a Network item. Windows Explorer Does show the Network Icon. I have tried, rebooting. I have tired making changes to preferences, but that icon does not show.

What is Preferences / Folder Tree / Options: Start Folder Tree At... set to? Try the default Desktop setting if it is set to something else.

Thanks Leo. That was the problem. It was set to This PC.
