Re: "sending activity history to Microsoft's servers"
"Bear in mind that they also have a habit of later disabling those registry keys. It used to be possible to disable the automatic downloading of spam apps (e.g. Candy Crush) through the registry, now you have to figure out the IP address they're being downloaded from and block them (for as long as that lasts)."
Can anyone recommend a good repository of detailed information about stuff like this? I am still on W7 and Linux, but my son is on W10 and although he's aware of privacy issues etc. he isn't a techie. Unfortunately I haven't had the time or pressing need to keep current on this kind of W10 knowledge.
