Can DUA install a XPE QFE directly?

[Eberhard Schefold]

I'm quite confused about a remark I found on the page

Installing Microsoft QFE #823980 on Windows XP Embedded (with and
without Service Pack 1)
http://www.microsoft.com/Windows/Embedded/xp/techinfo/blaster/blaster_xp
e.asp

It describes the manual steps necessary to patch an already installed XPE
device against the "Blaster" worm (copy DLLs, make registry entries).
However, it says:

"If your device has Device Update Agent (DUA) support built into it, you
can use DUA to deploy the embedded patch (located here) to your device,
eliminating the need to read this document."

The "located here" is a link to the regular QFE EXE that updates an XPE
*development machine*, i.e. imports .sld files into the Component Database,
copies binaries into the QFE repository folder etc.

My understanding is that executing this QFE EXE on an already installed XPE
device, i.e. a *target machine*, wouldn't make much sense, right?

Now I must confess that I'm not too familiar with the Device Update Agent.
From what I've read, it can download stuff on schedule, manipulate the
registry, execute processes and so on, interactively or with a script. What
I haven't seen yet is what the DUA can do with the QFE EXE, so that it
executes differently and installs itself onto a *target machine* in a
sensible way. In other words: If the DUA can execute the EXE in order to
patch a target machine, why can't *I* use the same EXE in order to install
the patch, without DUA?

I must be missing something very silly. Can you help me?

Mario is correct. If you want to update an existing runtime, you need to
open the QFE with Winzip. When the QFE EXE is expanded with Winzip you then
have access to the binaries that need to be delivered to the runtime.

Thank you both. I'm still not able to figure out what

"If your device has Device Update Agent (DUA) support built into it, you

is trying to tell me. Why wouldn't I have to "read the document", it tells
me the very things you wrote? I simply don't get it.

Hi Eberhard,

I have created this script and tested it on my embedded
machines and it works fine. If you want I can send the
script and related files to you. Just drop me an email
and I will get them to you.

Thank you, Robert, that's very kind of you. Unfortunately, DUA is not an
really an option for us. I was just trying to understand what the DUA is
able to do with the EXE that we are not.
