Lets take a look.
No commands in SFX archive. (other then launching the batch within.)
Virus total more or less clean (a few always get mad at SFX archives)
Emsisoft didnt find anything (its what im running on my rig)
7zip extracts it without executing it manually (this is good because it generally means the archive wasnt tampered with after creation)
seems to just be a batch
My comments are in green.

# now we are modifying registry entries, in this case we are adding one. In this case this is the windows auto proxy discovery service, the value of the "Start" entry is being changed to a value of '2' which means it is being set to automatic. This may be needed for certain windows discovery features so I wouldnt doubt xbox wants it. In short this is also known as WPAD and is a security vulnerability to be enabled. Though not super dangerous or anything if done.

and the he exits. Nothing inherently bad about it. more strict environments tend to have these settings disabled or off completely. However with what I know about xbox NAT traversal this could infact help.
