When using a home computer or sharing a server with other people, updates and reboots happen. What's really annoying is having to go and restart a bunch of game servers. On a shared server you have to inform everyone the servers are down, on a home computer it's easy to simply forget.
It would be much easier if DD had some sort of "start when Windows starts" setting. Something which would allow you to have it automatically host whatever game on whatever port whenever Windows boots up.
