Want to see all data Windows 10 sends Microsoft?

I remember using bitvisor (a very thin hypervisor like Xen but for intercepting sys-calls or hyper-calls) to see if Windows XP and Windows 7 send anything without being caught by the OS level firewall. It was actually but I never investigate further. So with a grain of salt, I would never trust what Microsoft provides a way to increase the trust of people who are worried. Also in this documentation, it doesn't mention what is the data actually but it only says some keys and ids.

I would like to see how the OS I have paid for (not everyone is just upgrading) can be stopped of monitorings. Granted I am coming from Linux and Mac but it took me a lot of time to find the checkboxes and there is still no way to know if I have unchecked them all and if they are adding more of these in the future updates. Which may be this tool can be helpful for me knowing oops I missed one of those apparently.

Yeah, I'd rather just block all of that stuff and monitor it on my own, but thanks for trying Microsoft. Or maybe I should thank the EU for the GDPR and the DPA's for forcing you to do this.

It would be an interesting test to see how much data gets sent from your average heavy computer user. I use a ton of software, and I always opt out of the request to send telemetry data to "help improve the software".

I was feeling bad the other day for not allowing a nice open source program to do so, but realized that my upstream line might be completely saturated with constant telemetry data if I didn't always opt out.

How about Microsoft just not send any data?
