Open a Command Prompt as Administrator
(Click your Start Button, type cmd, right click Command Prompt and choose 'Run as Administrator')
Run these commands one at a time and hit ENTER

net stop msiserver
Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

Type exit to quit Command Prompt, then restart (not shut down) your PC.
Then check if the updates in the settings app will install correctly.
