"(not sure on how virtual desktop + multiple monitors might work)"
My previous answer was determined with multiple monitors, as well as with virtual desktops. I run 3 1080p monitors on my desktop. Hopefully MS doesn't change it, unless they make it so a program opens on the same monitor which it is accessed from the start menu. As things stand now, a program will open where it was last running even if you use the start menu on a different monitor to open it.
