Thank you for that comprehensive reply. I knew that simconnect was something like a pipeline used to communicate data to and from the game. That being said, my thoughts were if it is poling the game, then it might be a source of some microstutters that I am having, so uninstalling might help.
Nowdays, the only addons that I use are ones that simply go into the community folder by use of addon linker…they do not go through a windows install routine.
I have created a restore point and will uninstall it and report back my findings.
