I encountered the similiar problem on my laptop.
and the following answer worked well in solving my problem:
Is this XP SP2, 32 bit ? If yes, then download the latest Windows Update
Agent from here:
http://download.windowsupdate.com/v7...gent30-x86.exe
Then download and save KB927891 if it has not been installed.
http://www.microsoft.com/downloads/d...displaylang=en
*** Change the Language if need be prior to downloading it ***
Save them, do not run them while the browser is open or the Automatic
Update service is running.
Close the browser and any other open programs.
Stop the Automatic Update service via services.msc for now.
Check to see if BITS [Background Intelligent Transfer Service]
is Started. If so, Stop it for now.
[NOTE: BITS only needs to be set to Manual for it's Startup type when
doing Automatic Updates or manual updates at the update sites]
Now install WindowsUpdateAgent30-x86.exe
Then install KB927891
Restart the system
