Automatically start OneDrive when the computer starts

This option should be enabled by default on Windows. If it is not working then check the following:

1. Click on the OneDrive icon on the taskbar and open "Settings":
2. Navigate to "Sync and backup" and make sure "Start OneDrive when I sign in to Windows" is enabled.
3. If the issue still persists then click on the start button and search for "Startup Apps". From there make sure Onedrive is enabled.

Click on the Apple logo and open System settings / preferences.

1. In the window search 🔎︎ for "Login items".
2. If OneDrive is not listed under login items then press the plus + button. Navigate to the "Applications" folder and select OneDrive".
