As it has just failed for some updates, try those again later.
You could Google for the stand alone downloads, but when you get the error there's a link that takes you to some suggestions for a fix, but they can be confusing.
If they still fail, then try these generic commands from a cmd prompt run as an admin.
The SoftwareDistribution cmd will clear your update history but will not affect already installed updates, but you can reverse the cmd to restore the update history.
The forum may allow you to copy and paste these cmds where they will auto run except perhaps for the last one where you will need to press enter.
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
If they report as successful then enter exit to close the cmd window.
