Thank you for the response. 

I went back and looked at my Config file for Teams in DEM and discovered I was missing the IncludeFiles section.  I added it and the first time I logged in it prompted me to click Sign IN on the screen where my userid was already filled it and then I had to type my password in.  I logged out of the desktop, logged back in and now Teams signs in automatically.  I have done this twice now and so far so good.  When I get into Teams, it takes me to the Teams section instead of Chat.  This is not a big deal but just curious if there is a way to make the default section Chat. 

Currently, my config file looks like this.  I left all of the entries in the IncludeRegistryTrees section which I know you have taken out.  Shall I remove the entries as you indicated?
