Hi there,
Getting a little frustrated with my Microsoft support experience so far,
hopefully someone here can help. Raised a case (although this has been closed
saying customer service support are only able to send a standard email and
not help with a technical request!) anyhoo - rant over.

Basically windows update is failing to install any updates. Won't check for
updates - all fails with code 800004002. Was eventually able to change the
options for when update checks/installs by turning UAC off, but still no joy
with getting the updates installed or working properly.

This sounds like a relatively common problem yet I haven't found a solution
that works yet. Problem text is below. For anyone with access the case ID is
SRX1087814491ID

Only other potentially relevant bit of info is when I try to register the
update dlls listed, QMGR.DDL returns an error:
The module "QMGR.DLL" was loaded but the entry-point DllRegisterServer was
not found. Make sure tha "QMGR.DLL" is a valid DLL or OCX file and then try
again.

Anyone confirm if this is supposed to be a valid file on vista? As I say, I
have tried reinstalling the update agent anyway.


Here's the problem text from the case:
Problem Description: For a while now, windows updates that have been
downloaded are failing to install.

In Vista when 'select to install updates and shutdown is selected' it goes
to the normal install screen waits a while on the first one and then skip the
others and shuts down - updates remin uninstalled

Additional symptoms:
Windows update (and windows defender update) fail to check for updates with
error code 80004002

I am unable to change windows update settings from 'install automatically
every day at 3am'. No matter what I change, after I press OK, acknowledge the
UAC prompt, the setting remains unchanged.

This has been happening for quite some time - possibly couple of months.

Following some suggestions in the knowledge base and forums, I have
attempted to do the:
- 'stop service, register dlls, start service'
- 'stop service, rename software store'
- reinstall latest windows update agent. Nothing has worked so far.
