Windows 10

You sometimes want to check if a program that you've installed is doing anything funky. While you could install a full-blown packet analyser like WIreshark, sometimes, that is overkill. A quicker and handier option would be to just rely on good old netstat. Like so:

as well as

-b: displays the program name (executable)

-n: displays the IP address

-f: displays the resolved form of the IP address

On a fresh installation of Windows 10, I found that Youtube was working just fine, but other embedded videos on sites like Twitch and Reddit were not. I thought it had something to do with HTML5 or flash, but as it turns out, it was because I had chosen the wrong version of Windows during the installation process. Choosing Windows Professional N or, basically any N version, results in video issues primarily due to the lack of appropriate codec and DRM support. Even Netflix will very likely not play. This also affects all browsers.
