I would suggest you to try the below mentioned steps and then try installing the updates after:
•Click on Start, and then RUN.
•Double click on 'Background Intelligent Transfer Services'.
•Under startup type: Automatic (delayed start)
•Under service status: 'Start' the service
•Now try to download OS updates.
You can even use the Windows update reset component to reset the Windows update settings on your computer.
From the link below run the “Microsoft Fix-it” to automatically reset the Windows updates components.
