just open extended services and switch all dell entries and SftSerices(Soft Think Agent Service SAS) from automatic or delayed start to manual and it did not pop up notification, what else messes up, don't know yet but at lease got rid of backup and recovery notifications with out uninstalling it.
So I was updating Dell Backup and Recovery after upgrading to Windows 10, and I hit the "Finish" button when the process was complete.  Dell Backup and Recovery then restarted my PC without asking me if I wanted to do so, and while I had a number of unsaved files open.  REALLY, DELL???  Your program that's supposed to prevent data loss is designed in a way that causes data loss???  Are you kidding me??? And it still doesn't look like there's any way to turn off the obnoxious notification boxes that keep showing up and asking me if I want to upgrade.  I especially love it when those boxes pop up in the middle of my screen when I'm trying to give a lecture.  
Dell Backup and Recovery for Windows 10 -- Really???
