Microsoft opens up on Windows telemetry, tells us most of what data it collects
The actual list of what it gathers: https://technet.microsoft.com/itpro/windows/configure/config...Included:"Storage attributes, such as number of drives, type, and size" -- So ID numbers of all USB storage drives you've connected? Better not put sensitive data on a USB and send it to a journalist..."the number of crashes or hangs, and application state change details, such as how much processor time and memory were used, and the total uptime for an app." -- To e.g. determine when you used the TOR browser, since the difference in uptime between two time points is how much it was up during that interval."App usage data. Includes how an app is used, including how long an app is used, when the app has focus, and when the app is started" -- Oh, never mind, they also explicitly state they gather which apps you have installed and how much and when you use them in the next section."Accessory device data. Includes a list of accessory devices, such as printers or external storage devices, that are connected to Windows PCs and whether these devices will function after upgrading to a new version of the operating system." -- Print poster and glue it to a wall -> Printer gets identified via tracking dots ( https://www.eff.org/pages/list-printers-which-do-or-do-not-d... ) -> Printer is linked back to you, even if you bought it with cash. I hope you didn't print anything your local sheriff would dislike!Edit: This is all in the 'basic' level, which you can't disable.
