I followed the steps above, uninstalling reinstalling and rebooting. I get the same result. The puzzling part is the drop down displays a different list of options.
If I try to just start the GlassWire Control Service, I get: Oops, new users are only allowed one image, so the error dialog that comes up says:
Windows cannot start the GlassWire Control Service. Error 1075: The dependency service does not exist or is marked for deletion."
I know I must be overlooking something simple.
