We weren’t the first ones to get a call from an Indian-sounding guy saying he was from “Windows” (later he gave the name of his company as Global Intelligent Tracking Services) and contracted by Microsoft to call us and fix something on our computer. It seems like the scam’s been around in the US for a while, and the Swiss government has a post warning of this scam. I can add that their phone number showed up as 001 253 802 0308, a US number with plenty of complaints filed against it.
