If their software is so sophisticated that they can not only find a problem PC and the owner's phone number, then it should be possible for them to tell you which of your two (!) computers is at fault and what operating system it uses.
One wonders why, if all these Microsoft PCs are showing these faults, there have been no patches to sort it out and why consumers are only able to get the problem sorted after a phone call.
Personally, the best solution is to tell the caller that you use a different operating system. The Zorki 4 has had no problems of this sort.
