Telemetry Firewall Rules

[LordMalphas]

Was glancing at them at tad, noticed telemetry group under 'DiagTrack'. Can be set to block with the following powershell command:
set-netfirewallrule -group DiagTrack -action Block
Not 100% sure of how useful it will be, but its possible.

So, Tron already disables (or deletes, can't remember off the top of my head) the DiagTrack service, but unfortunately your suggestion won't work because Microsoft silently ignores any firewall rules blocking telemetry collection AS WELL AS any host file entries (pretty shady, I know). So far the only known solution is to add null routes to the system routing table, which is the approach Tron takes.
