Solved - WU hangs - error 0x80040154

I was having problems with Windows Update hanging. Looking in
c:\windows\WindowsUpdate.log, I had error 0x80040154, which seems to be a
problem with a com object not registering. Don't know why.

The solution is to register by hand each of the WU dll's.

Open up a command prompt then key in
C:\WINDOWS\system32\regsvr32.exe /s "C:\WINDOWS\system32\wuweb.dll"
and repeat for all of the dll's in c:\windows\system32 that are named
wu*.dll (Hover the mouse over each to see the description that should mention
windows update).
Run windows update as normal and it should work now...

"ordinateur",

If you run into this issue again, copy and paste the following into a file,
and give the ending file extension a .bat or .cmd (works on Windows XP):

NET STOP WUAUSERV

regsvr32 /s cdm.dll
regsvr32 /s bitsprx2.dll
regsvr32 /s bitsprx3.dll
regsvr32 /s iuengine.dll
regsvr32 /s qmgr.dll
