I've split your list so that it's easier to see which patches we're talking about here.
Now then, something seems to have gone pear-shaped with your system because all of them a fairly old. In fact, KB2518864 dates from 9 June 2011 and was replaced in the May release this year by KB2604092. You can see that in
this bulletin
So the system shouldn't be trying to download the old patch again. That's probably why it's failing i.e. because Windows File Protection won't allow it to overwrite a file which is much newer.
It's a similar story for the others.
What I suggest you do here is the go to the Windows Update site and click "
Review your update history". Make a note of any installation failures and then go to
Start |
Run, type
%systemroot% and click OK. The OS records a log file for each of the failed installations. Find the ones that match those and see what you can glean from them.
