Steam crap telemetry

Steam crap telemetry slows down games. U notice that when u go offline and turn your game on. If u say slowing games is because network traffic when u are connected its partly true. When u start game after couple min game is slowing down because not all crap connected to spy on u. ITS LIKE MORE THAN 20 NETWORK PROCESSES!! TO RUN ONE GAME. Its ridiculous. Searched net but nobody have clue how to do it. They say to block ports but new are opened. It doesn't work.
Thanks for help.
How to debloat, maybe disable those pesky launcher telemetry or slim it little bit?

Sadly, these are the days where you cannot get away from telemetry and spying by some software. You're likely to find that if you do manage to stop all of those processes, that your games likely won't work anymore.

And that in itself is really sad.

Go search about HOST list for windows.
You need to edit your HOST files first.
IDK about "Telemetry" but remember to free up anything else via "Shut Up Windows 10/11".
Sometimes you have background services turned off as well.

Again I am sorry your having this problem. I have no idea why steam is doing this to you.

Thx guys for answers.
