If windows isn't the active OS it can't report on anything outside of it's segmented memory storage because it's not formatted in a configuration it knows. While you're in the other partition, it can't send any telemetry data, or capture screenshots of your computer and save them to microsoft servers. While you're not booted up in windows, it's an inactive partition/portion of system memory. It can report whatever it wants on my 'work' portion of my computer, but is clueless about files/info on the other side of the partition.
