I had a funny issue with Windows 10 a few years ago.

I tried to start cmd.exe and nothing happened. Tried a bunch of times more. Still nothing...

I was connected to a WiFi network that allowed ping to the entire Internet but not TCP connections. Then I switched to a WiFi network that allowed TCP connections to the Internet and 20+ cmd.exe instances started all at once.

I thought: "Wait, that can't be true", but it was reproducible.

This makes me wonder if launching programs takes longer on a slow internet connection.

I do not know if this still happens as I have only used Windows 10 on a handful of occasions since then.

I’ve had the same happen in macOS, which would slow down to a crawl when my network didn’t work correctly (quietly dropping packets).
