Well... it's not. Both Linux and Windows are stable enough and depending of your skills, both can be equally secure. Out of the box, Linux is more secure though. The only real advantage I can think about is that with Linux, you won't need to reboot the system when applying patches/security updates (if you are not upgrading your kernel, of course). Another good thing is that you can run Linux in command-line mode only, thus saving resources for other crucial operations, as running the server itself.
If you don't care about uptimes (and in a game server it's not all important as it should be with a Online store, for example) and want to install things by double-clicking and/or lack Unix administration skills, Windows is fine. If you do, need a server with higher uptimes, less hardware demanding and low costs and has the skills/willing to learn Unix/Linux, than Linux is the way to go...
By the way, I just saw that this is your first message here. Welcome to LQ.org
