It isn't one of the "common" Windows Update errors (see
http://support.microsoft.com/ph/6527/). But clearly, something isn't working
correctly.

0x80040002 is a standard COM error meaning E_NOINTERFACE; that is, some COM
DLL on your system is not correctly registered, hence the Windows Update
process cannot find the Interfaces this DLL exports. Exactly which DLL is
hard to say, from here. But once you find it, it should be easy to
re-register - you go to a Command Prompt as Administrator and run the
command:

C:\>regsvr32 foo.DLL

where you replace "foo.dll" with the name of the specific DLL in question.
Then run Windows Update again, and it should work okay.

To get more details about the error, look in the file
C:\Windows\WindowsUpdate.log. This is a plain text file which you can open
in Notepad. If you seach for "8004002" or "E_NOINTERFACE" you should find
the error in the log, along with more details about the files involved. If
it isn't obvious from the log what you need to do, cut-n-paste the relevant
section of WindowsUpdate.log into a message to the newsgroup. For issues
around Windows update, you might be better off asking in
microsoft.public.windowsupdate - that group is 100% focussed on Windows
Update problems.

Try this it worked for me

Re-register the Windows Update DLL with the commands below:

1. Click on 'Start', choose 'Run'. In the open box, type cmd, and then click
'OK'.

2. Type the following commands. Press 'ENTER' after each command:

regsvr32 wuapi.dll
regsvr32 wuaueng.dll
regsvr32 wuaueng1.dll
regsvr32 wucltui.dll
regsvr32 wups.dll
regsvr32 wups2.dll
regsvr32 wuweb.dll

Try Updating Windows.
