Everyone using Windows should install a telemetry blocking program. This one just adds all Microsoft telemetry IP addresses into Windows Firewall with a "block" setting.

Just don't use the "Add update rules" feature because that blocks Windows Update. Just add the telemetry rules.

In addition, you can also change the IP address Windows uses for the "Am I connected to the internet?" test that Windows does all the time. Instead of letting Microsoft know every single time you boot your PC or connect to WiFi, you can instead have it check a Debian server. Or a Mozilla one, I think.
