Controlling Vista Updates

Sometimes you want to change the Auto Update settings, but you can't. The images we get for vista have had some amount of pre-configuration done to them and you cannot change any of the settings.

Supposing you want to install the new service pack, or set up sysprep? You can't because the machine immediately starts downloading every update since time began, getting in the way of the SP and work your doing.

You can change that by removing the AU... key in the registry as described here.
