Sadly, I'm going around setting the GPO to block 1809 for now. I need to get a better handle on what to expect. Usually, I just roll it out and have next to no problems. But today wasn't fun. Many one offs, where 99% of the computers were fine, but a few had problems. The biggest rub is not having any way to disable the firewall notifications in the action center. The way we have done it in the past is no longer there, and no results yet on Google for a real answer.

Had to completely uninstall/reinstall UPS Worldship
One computer had to reinstall Adbobe Cloud Installer
One computer had to reinstall Extensis UTC
Something else I'm forgetting
