How do I configure my Windows 10 firewall to stop sending telemetry to Microsoft?
> kek (if only it was that easy)
In all seriousness though...
Is there any way to block all internet connections by default and get asked every time software wants to access the internet?
Why would they hardcode ip addresses of telemetry server?
Because they knew someone ( maybe a few percent users aka bit advanced users) would use hosts file to avoid the connection. They wanted telemetry from _every_ machine. They would get huge data from all those dumbass users yet they seem to target a minority of tech savvy users as well.
Why is Microsoft being a dick here? The answer is quite obvious.
Stop using telemetry infested OS. You could use a clean install of win7.
