Your home computer is the perfect machine. It's customized to your exact needs, runs all your must-have apps, and holds every important file you'd ever need to access. The catch: It's not exactly practical to lug a computer with you everywhere you go. That's where remote access comes in. Here is the simplest way to control your home computer from anywhere as though you were sitting directly in front of it.
Download and install TeamViewer on both your home computer and remote computer. Start it up and create an account by going to Connection > Set Up Unattended Access. This will make all your computers accessible over the internet with just a quick username and password combination.
Log into your account on your home computer. You should see that it's already been added to TeamViewer's list of machines. Leave TeamViewer running in the background when you leave the house.
Run TeamViewer on your remote machine and log into your account. You should immediately see your home computer in the list. Double-click on it to start a remote session with that machine.
It really is that simple. Sure, it requires creating an account and downloading extra software, but it's totally worth it. You can share files between machines, you can view multiple monitors, and configure advanced View settings to make it run as smoothly as possible.
Note that TeamViewer also has an iOS and Android app, if you want to connect from your phone, as well as a web client, if you're on a friend's computer and don't want to install any extra software on their machine. Plus, it has support for wake-on-LAN, which means you can put your home computer to sleep and wake it up when you want to use it, all without being in front of it.
