I can confirm this works fine on windows 7 enterprise 32bit for me. Has anyone got this working via group policy? The dll is owned by trustedinstaller so I think simply defining a group policy to delete or to over write the original does workn't (at least for me). I get the blank box until i manually delete authui.dll and then allow the group policy to copy across the modified version. So I assume the policy is getting a access denied msg when it trys to over right the file. It Would be nice to have this all done via GPO's. Any ideas?
