6. WSL: fix \_z\_precmd:1: nice(5) failed: operation not permitted

By default, zsh tries to run background jobs at a lower priority, which Windows won’t let it do. A good workaround is to put

case $(uname -a) in
*Microsoft*) unsetopt BG_NICE ;;
esac

in your .zshrc file. That alters zsh‘s default behavior and fixes the problem entirely, in my experience.
