If you're thinking of doing this on your home Windows box, you need to rethink that plan.
I don't know why people keep propagating the idea that Linux is inherently secure. If you set up any kind of server without any knowledge of what you're actually doing, setting it up on Linux won't help you shit. If you don't know about security stuff setting up a server is generally just a bad move and should be thought over. Please stop spreading that irresponsible "Use Linux and you're perfectly safe" myth. The penguin is not going to magically secure you if you don't know how to make use of its tools.
edit: Rant over. No offense!
The bit about running a masternode on your home Windows box was actually more about factors like uptime, bandwidth, generally knowing what you're doing when you have 1000 DRK at stake etc.
No offense taken BTW, I am thick skinned, and people tell me while facepalming that nothing ever sinks in.
