Group Policy "Extra Registry Settings"

That happens if you remove an .adm template from a GPO without first setting the policies defined in this template back to "Not configured".
You need to re-add the template that you used to define these settings to the GPO, set the policies back to "Not configured", then you can remove the template again.

I'm not sure which .adm template it was.  Any way to determine what template I need to download from MS.

Check which keys are mentioned in the "extra registry settings", and try to find out from which context they could come; it's your only point of reference left. Unfortunately, there's no list of "last templates used" like in Word ...

I tried adding the the windows XP .adm files and it doesn't show up under the Resultant Set of Policy anymore but it still doesn't show a setting in the Group Policy Manager.  Any other ideas?

In the View>Filter menu, make sure the box for "Only show policies that can be fully managed" is unchecked (and the box for "Only show configured policies" is checked, to make it easier).

Ok I just tried the filter setting but that didn't show me anything extra under the Resultant Set of Policy and it still doesn't show up under the GPO.

These are just view filter settings for the GP Editor, you won't notice anything different in the RSOP; when you now edit the GPO from which the "extra registry settings" were coming from, you should find some policies (either under Computer Configuration\Administrative Templates or User Configuration\Administrative Templates) that are set.

Below you can see a list of the policy

These control the popup blocker of XP SP2 / W2k3 SP1. Can't check it at the moment, they might be in the inetres.adm file of an XP SP2 or W2k3 SP1 machine, or from a customized adm template.

Ok but the one I'm really interested i now is the Windows update.  It is not showing up under extra reditry settings or Administrative Template/Windows Components.  But if I go and run Resultant Set of Policy it Shows up using this policy.
