Hello,
There's a pretty easy way to keep it from starting or from preventing it to run on startup. This will not uninstall it, but it does keep it from sitting in your system wasting resources and spying on you. You may try these following solutions;
1) Start the task manager.
- Then click the SERVICES tab.
- There you'll see Onedrive listed along with a few others.
- Right-click Onedrive and click DISABLE.
2) In the lower right corner of your screen you have a small up pointing arrow. Click it.
- Among the icons you'll see will be one for the cloud. Right-click it and click Settings.
- There you'll see a check box for starting Onedrive automatically. Uncheck it and click OK.
