Setup: Windows 10 v1809 OS build 17763.55 (latest). Docking station with two external monitors connected and laptop screen being used as well.
The issue is a delay in startup and unrelated to any deliberate delay imposed by the OS. I had to also do a fresh install. I've also noticed that if I disable or remove the two startup entries for Fences, it can still activate after an interaction with the desktop (i.e., by right-clicking). Not sure why it would launch.
Sticking to the original post, my system is delayed upon login with Fences enabled. At times, I don't even see the taskbar and I have to unload explorer and then reload it. Either that, or sign out and back in again.
