When one drive doesnt want to start at all

This could happen if the OneDrive has been disabled by a Policy setting, either manually or by using a 3rd party program. For example, if you used Spybot Anti-Beacon to stop tracking issues in the Operating System, you may have inadvertently disabled OneDrive. To make OneDrive function again, disable the Policy in the respective program.

Alternately, right-click Start, and click Command Prompt (Admin). Type the following command and press {ENTER}:

 

reg add HKLM\SOFTWARE\Policies\Microsoft\Windows\OneDrive /v DisableFileSyncNGSC /t REG_DWORD /d 0 /f

 

Now start one drive. It will show now.
