Did you know that you can make a Sony PlayStation 3 Sixaxis controller work on a Windows PC? All you need is the right drivers and it 
can be done. I’m running a Windows Vista Home system and got it working on my machine, and even played a game with it. This article will provide details on two different methods of how to make it work in either Windows XP or Windows Vista.

Before we begin, you should know that I have worked in the computer field for over a decade and have been using computers for another decade on top of that. I am very knowledgeable when it comes to installing hardware and software, so much that I have certifications to prove it.
The drivers required to make the PS3 Sixaxis controller work on a PC are homemade and not officially licensed by Sony or Microsoft or anyone else, so it is at your own risk that you install them on your computer. If you aren’t comfortable with that sort of thing, my best advice is to just go buy a game controller for your PC and not risk screwing up something. Continue at your own risk.
Before you begin, make sure you power off the PlayStation 3 console by flipping the switch on the backside of the unit, next to where the power cable plugs in. If you don’t, you may turn the system on when you hit the PS button on the controller, and this could cause it not to work right on your PC. I read several message board threads where people could not get the controller to work on their computer until they turned off the PS3.
Now that you're aware of the risks, continue reading for instructions for both Windows XP and Vista...
