FIRST:
If you have Windows XP, these are suggested steps to clean up after a failed Windows Update attempt.
Housekeeping and cleanup steps:
Bring up Windows Explorer / Tools / Folder Options/ select VIEW Tab and look at all of settings listed.
"CHECK" (turn on) Display the contents of system folders.
Under column, Hidden files and folders----choose ( *select* ) Show hidden files and folders.
Next, un-check Hide extensions for known file types.
Next un-check Hide protected operating system files.
Use Windows Explorer. Go to C:\Windows\System32 (or \WINNT\System32 )
If you have a sub-folder called * Catroot2 * (not Catroot) rename the
folder to CR2OLD. Or delete everything in that folder. Just make sure you do the right one.
(to clean up downloaded files for Automatic updates / Windows Update)
From main Windows Start menu, select RUN, type in
CMD <Enter-key>
type in
net stop wuauserv <Enter-key>
Go to Windows Explorer.
Look on your system drive (usually C ) and look at the Windows folder name. Like Windows or WINNT.
Modify following as appropriate.
If your Windows folder is C:\Windows. Look at this folder
C:\Windows\SoftwareDistribution\Download
If you find files in there, delete them. That folder is where files are stored from W U downloads.
Go back to Command prompt window.
type in
net start wuauserv <Enter-key>
EXIT <Enter-key>
SECOND:
Go back to Windows Update, but then select View update history. (When you first get to website for Microsoft Update-Windows Update, look at left-hand column, under Options. Press "Review your update history".)
If this is on V6 of Windows Update, you should be able to click on that error note (the red X), and see some info.

Turn off your AV program (temporarily), logoff system, do a fresh Windows start, and then retry Windows Update.
