I'm sorry if you felt flamed, that was not my intention. I am only looking for other possible logical explanations. The 4 GB overage with any type of Windows computer involved in early August still remains highly suspect for the automatic Windows 10 download, even if you had automatic updates turned off. We have had several confirmed cases already. Each of them was an initially unexplained 4 GB of data in early August. If you go back and look, some of my posts were answer other questions which you assumed I was answering you. Again sorry for the misunderstanding. If the usage continues, I hope you consider the data measurement tools so you can really get to the bottom of it.
