This is a new hack/glitch to get free Microsoft Points. It fully works, I've gotten over 20,000 points off it.

Put USB into Xbox and power on Xbox. It might say their is a virus in it. Don't worry their isn't. Any kind of hacking file on a computer will show up as a virus. So don't worry. I promise. Disable your virus protection before downloading it otherwise it may not work. I've made the program my self. It does NOT have a virus.
