Yes, I have already set that up - it was the apparent lack of a similar feature for Windows devices that I was wondering about. In the example I quoted, ESET creates a phantom account on a Windows device (PC, laptop or whatever) and if the device is stolen or lost and someone logs in via the phantom account, it prevents access to the real accounts and starts sending information about the location of the device/takes mugshots, etc.
