This Microsoft tool helped me shut down the startup apps that Task Manager wouldn’t show me

Windows Task Manager, as well as the Startup Apps page in Windows Settings, can show you which apps automatically start when you log in and let you disable the ones you don’t want launching with Windows. But what you see in Task Manager’s Startup Apps tab is only a small slice of what’s really going on under the hood during startup. If you want to see the complete picture, you have to use the Autoruns utility.
