I thought this little app might be useful. If you are using the Xbox 360 wireless controller with the USB receiver you may have noticed the Xbox "Guide" button will turn on the controller, but not off. This little app fixes that. It makes it so that once you hold the "guide" button on the controller a prompt comes up allowing you to turn off the controller.
It flags as a virus on my pc, but it is not, it is made with AutoIt which most anti-virus programs associate with a malicious file. It works fine on my PC and makes controller use more streamline. You can view the author's page here
