Rooting is the Android equivalent of jailbreaking, a means of unlocking the operating system so you can install unapproved (by Google) apps, update the OS, replace the firmware, overclock (or underclock) the processor, customize just about anything, and so on.
Of course, for the average user, rooting sounds like -- and can be -- a scary process. After all, "rooting" around in your smartphone's core software might seem like a recipe for disaster. One wrong move and you could end up with bricked handset.
Thankfully, there's a new Windows utility that makes rooting a one-click affair: Kingo Android Root. It's free, and based on my initial tests with a Virgin Mobile Supreme and later ones with an Asus Nexus 7, it works like a charm. (Be sure to check the compatibility list before you proceed, keeping in mind that even if your device isn't on it, the utility may work with it.) Here's how to get started.
