Maybe THE premiere tool for managing everything that starts with Windows, it hasn't seemed to receive as many recommendations or as much attention over the last few years, possibly because it was too powerful, letting you ruin your copy of Windows if you weren't careful. But with Win11 it may again see widespread use... the current build of Win11 seems to have lost the page in Settings where you turn on/off whether an app starts with Windows. Task Mgr. still works, but it strikes me as unintuitive for most people.
