Dell Dock and Win 10

I have a Dell Inspiron 570 running 64 bit Windows 7 with a Dell Dock that came pre-installed. Recently upgraded to Windows 10 and all was well until first auto update when Dell Dock disappeared. Tried numerous ways of reactivating and reinstalling but would not work. Eventually restored computer to pre update but still running Win 10 and all is fine. Have deactivated auto updates. However would like to receive updates for security reasons but do not wish to lose Dock again. Any ideas? Many thanks
