What is? If you mean the Rewards program, you're thinking of Microsoft Rewards. That's a different program from the Xbox Rewards program. Xbox Rewards was run by a third party and ran at the same time as the Microsoft Rewards program for a while. Microsoft eventually shut down the Xbox Rewards program and opened the Microsoft Rewards program to more countries.
