The solution is VNC and a Dynamic DNS service like No-IP. VNC allows you to remotely control your computer but because many people hace dynamic ips that is hard because your IP can change at any time. That is where No-IP comes in. No-IP is a client software that updates a free subdomain like example.no-ip.org to your IP every time your IP Changes.
This howto will cover installing UltraVNC a VNC server and client, how to set up UltraVNC, and how to set up No-IP.
UltraVNC


Check the boxes that are checked in the picture on the right and continue to press next until you get an error dialog that says "the machine has no default password set" like the picture below.



No-IP
First if you do not have a No-IP account, create one by going to no-ip.com and registering.

It will send an email to you so you can verify that you want to create account. Click the verification link in your email and it will send you back to the No-IP site.

Log in to the site with the account you just made and click Add under Hosts / Redirects.

Write whatever you want for the subdomain and choose a domain for it to be under. I chose howtonoip for my subdomain and chose to put it under their no-ip.org domain. Scroll down to the bottom and click Create Host.




You are now done configuring everything!
You may access your computer remotely from anywhere by pointing your webbrowser to the no-ip address you chose and using port 5800. Like example.no-ip.org:5800
You may also copy vncviewer.exe located in C:\Program Files\UltraVNC to a flash drive or your email and run it anywhere to connect to your computer. You only have to put the no-ip address into the VNC Server because it is set up to use default ports.
Note: Make sure to port-forward TCP ports 5800 and 5900 to the computer you set up VNC on so that you may access it from outside your network.
