How to disable OneDrive automatic Sync files:
it is easy to disable the sync of OneDrive. Just right click on the notifications icon and select OneDrive. When you right click on it, you will see several OneDrive options including "Settings".
Clicking on "Settings" launches a dialog box with "Settings" and other tabs. In the "Settings" tab, you can Uncheck “Start OneDrive automatically when I sign in to Windows” if you do not wish to start OneDrive.
