You would think regmon (i use regedit->export, because I am old), would do it but if you read Al's link to thread above, you can see the frustration level of trying to set this setting on the user's behalf (apparently this stuff needs a wkstn restart!) ... excellent link Al, printing it off now.

Why oh why does Microsoft make it so hard to manage settings like these. Why do they continue to use registry binary blobs when they know they're not GPO friendly, or even scripted poke friendly. sheesh.
