Since, OneDrive is deeply integrated with Windows operating system, it has a natural tendency to automatically startup with the computer, which is designed to make it easy for users to sign-in to OneDrive and start using it.
While this default setting is ideal for signing-in to OneDrive and allowing it to perform its cloud related services, it is of no use to those who are not actively using OneDrive or not at all interested in using OneDrive.
Hence, we are providing below three different methods to stop the OneDrive App from starting up automatically on your computer.
