Hi Fellow ROG,
I just got the bluetooth Microsoft Arc Touch mouse today for its form convenience. Spent all afternoon trying to pair it to my laptop without success. Turned out that the Intel bluetooth driver is not up-to-date. Here is the link I found for downloading the latest driver from Intel. Hope this help anyone else in the same situation.
