What Is It & Why Are There So Many in Task Manager?

Host Process for Windows Tasks is an official Microsoft core process. In Windows, services that load from executable (EXE) files are able to institute themselves as full, separate processes on the system and are listed by their own names in Task Manager.

So, I’m going to lớn assume it’s the service that monitors for when I press any of the media keys on my keyboard (volume, mute, và so on) & delivers the appropriate commands where they need to lớn go.

No, you can’t disable Host Process for Windows Tasks. And you wouldn’t want to lớn anyway.
