By default (unless you know to opt out at installation), Windows 10 sends “web browser history, favorites, and websites you have open” plus “saved app, website, mobile hotspot, and Wi-Fi network names and passwords” to Microsoft. All of these will be available to police! It should be presumed they will also be sold to advertising networks. Oh well, at least on Windows 10 you might get email spam “relevant” to what you have been using the computer for. Expect junk mail and telemarketing calls at all hours of the day or night to also get and use this information.
