Sysinternals (winternals) tools are so useful ! There is something for everyone there (TcpView, ProcExp are my personal go-tos). MS was well inspired to buy it and hire M. Russinovich.

I like the enthusiasm, but I’m sure you realize why Jellyfin is more suitable for mainstream use. The pretty web UI, user management, watch tracking and device-specific clients are what makes the software actually useful if you want to serve media to “normal” people.
