I've been looking for a ways to block certain network traffic, that W10 uses to send out information of what the user does, obviously without users consent.
As windows firewall is far too cryptic for me to figure out, I've tried other things like Tinywall and Simplewall, which may not be firewalls per se, but rather ways to interact with windows firewall.
So far, I'm not quite sure if they are able to totally block that kind of traffic. Or maybe I just haven't yet fully grasped how they work.
Just an example: In W10, when clicking the network icon on the taskbar, and opening network settings, SystemSettings.exe sends every time query to
www.bing.com, trafficmanager.net, edgekey.net and so on.
That can be seen by using Wireshark, or simpler one, DNSLookupView.
I know this is nitpicking, but I just don't like that kind of hidden activity at all. Some say that microsoft uses such data to improve window's features. Really? They don't have enough hired brains to do that?
Anyways, there are at least some tools to try out, that I've found so far: Powershell based program from Chris Titus website, and Blackbird.
I've tried CT's program to strip some bloat (using its 'desktop' -option), and yes, it seems to lower the number of services. But then again, the video, where he explains how to use it, is mostly about gaming performance.
Another one, Blackbird shows (perhaps at least some) elements that are used for telemetry/spying. Disabling all of them actually breaks some of the windows features.
W10 version 1903 has things like:
InputApp
CloudExperienceHost
StartMenuExperienceHost
ShellExperienceHost
All of them are located in Windows/SystemApps -folder. "Experience" this and that, as long as you give us your data.
End of the rant.
