Setting up remote desktop

[Teny]

I have set up remote desktop back then before. However, I set up using what was included in Windows 7. I was only able to remotely access my desktop when I was at home. Now I want to be able to access my home desktop PC with my laptop when I am in school. Now, how can I set it up so I can access my desktop PC remotely from another location. Both PC will be using Windows 7 and is connected via wifi.

EDIT - Scratch that. I found a guide online that teaches me.
