I do have a 15 R4. I checked the Documents (there is no "My Documents") folder and didn't see anything similar to alienware command center in it. However, I did see something similar in C:\ProgramData\Alienware\Alienware Command Center. There is a folder named FXMetadata with a few json files in it. By the way, I am now on version 126.96.36.199 of Command Center and the problem persists.
