How do I disable Nagle Algorithm on a Windows Vista for Mabinogi? Please help me. Thank you very much. :D?

Yeah, I would need an explanation in a..how to put this, in a non-smart way? -sighs- I'm not very good with a computer and I would need a step by step kind of thing. Please dont leave anything out. I tend to freak out with every little thing. I suck at this stuff. I load my fire magic like WAY TOO slow and I get seriously pissed when I end up dead fighting a boss. I thank all who help me on this.
