A brief summary is that ONLY local administrators can executing the downloading and installation of Windows updates. I've tried a bunch of different GPO settings. Creating NEW local admin accounts works fine, however, adding any DOMAIN account to the local admin groups fails to enable that user to use Windows update. The user gets the update notification, but when he clicks the balloon, the screenshot below shows up. Everything works great in XP, so I'm inclined to believe is a security issue. I've tried disabling UAC, to no avail. Please help, this is the only issue so far Here's a link to my issue, witha screenshot. http://episteme.arstechnica.com/eve/forums/a/tpc/f/99609816/m/136006225831 Thank you for any assistance that can be provided.

A bump hoping someone has run into this.
