Same scam as others regarding PC being infected and about to crash. Wanted to remote my system. Had an indi accent. It was really funny as I work for one of the largest security providers in the world so I led him on a bit by following along his instructions to check event viewer, etc. Asked how they got the anonymous statistics to show my specific system was going to crash. Microsoft Cust Experience Pgm states the information will never be used to contact you so there is your first clue Sherlock. I wrapped it up telling him he was full of BS basically, but in a lot more words.
