I've tried the stock Windows shell and utilities. `ls` is noticeably slow in directories with like 15 subdirectories. That's not acceptable. Even the terminal emulator is so slow pasting 30 characters takes several frames. That's not too annoying, but I might replace it with Wezterm or something.
The stock Windows terminal experience is awful. Windows has improved markedly recently with `winget`, so maybe they'll get around to fixing the speed sometime, too.
