I want my unattended setup to automaticly update the installation during/after the install. Is there an unattended switch to have the installation connect to windows update and install what it find. Perferably silent.

I have tried DUDisable = No but it seems to have no effect what so ever.

Can this be done and how?

Dunno about Windows Update but for SUS server it is only to add some entries to the registry and off u go...

Required entries for SUS can found @

DUDisable refers to the portion of setup that would have run if you installed through windows. There is a screen in there that asks if you want to download the latest blah blah blah.

You could always see about Automatic Updates. Its installed by default. You just have to start it.
