Hi;

Open the Services list (enter "services.msc" on the Start/Run line) and
check that Automatic Updates, BITS (Background Intelligent Transfer
Service), and Event Log are all set to Automatic.   The AU and Event Log
services should be Started.   If the BITS service is not started, then
highlight it and click the Start option.  Does it start without errors?

If BITS does not start without errors, you can download and manually
install this update which may resolve the issue:

-c906850ab9f2&displaylang=en

Once that is installed, go to the Windows Update site and do a Custom
scan.  Select only one of the updates offered (unselect the rest).
Attempt to download/install that one update.  If the succeeds, then do
another scan, pick just one, and install that.  Repeat the one-at-a-time
thing until all 6 of those updates are installed.  BTW, if you get
prompted to do a Restart after any of those, please do that Restart
right then before doing other items.

If some of the items install but some won't, make a note of which ones
give you problems.  Also check the C:\Windows\WindowsUpdate.log file for
entries related to that last failed update and copy/paste that into a
clean Notepad document.   Do the same for each update that fails.

If none of the updates will install, note the Error numbers listed in
the WindowsUpdate.log file for each attempt and post back with that
info.
