DVD Label Name In Explorer

I have somehow managed to once again loose the ability to display the label name of a loaded cd or dvd. All windows will show is the generic name
DVD Drive. I fixed this several months ago with a patch but I have misplaced the patch. Does anyone remember hoe to restore this function?
(1) Clicking on the refresh button does not work.
(2) This is not an autoplay issue. The problem is the display of the actual disk label
(3) The name will not show up even after a restart with a disk inserted in the drive

Any help would be appreciated.
