That's possible, but the problem isn't so much in my session being lost as it is in my services and processes not running anymore. I host a Plex server on my machine that serves the whole family, I rely on it for remote SSH if I need to get into the network from the road, I share files to clients from it, and so forth.

Really it's too important to take down very often. I've considered buying a separate box for Windows. I run Windows applications in either WINE or VirtualBox, but with games that don't support WINE, that doesn't work unless you have specific, hard-to-find hardware and an extra GPU. Since games are the only thing I'm missing out on, more and more games are getting Linux native versions, and I don't have much time for games anyway, I haven't actually pulled the trigger on the separate Windows machine yet, but one day I will.
