Ask HN: Why is my Windows computer running 10,000 threads idling?

I noticed today in my Windows 11 Task Manager that I have ~10,000 threads. If I kill all traces of Chrome it's still at ~8,000. Sorting by thread count, System is ~500, Explorer is ~350, then it tails off. I do wonder why Dropbox.exe needs 250+ or Steamwebhelper.exe (Steam itself is not running) needs 100+ threads to operate.

It's not a problem, my computer is super fast, I just wonder how we got here from super optimized Quake engines..
