Windows 10

This post lists the internet communication targets of the Microsoft Windows operating system, including its various services and UWP apps. This post is a part of my application network connection monitoring series, a group of articles that explain how to analyze the network traffic of any Windows or macOS app.

I came across this problem while preparing my sessions for this year’s conferences. The setup is boringly simple: a user with a roaming profile logging on to a Windows 10 machine. The interesting part: every second time, loading the roaming profile would fail - causing a 35 second logon delay. Every other time, it would work.
