I wouldn't describe the deletion of the entire list of contents in WM as an "improvement".
I discovered too late that this is where the sudden inclusion of 95Mb / 5900 files had come from and fortunately had a recent backup of the WM directory to restore from
I have gone back to build 1666 for the moment rather than uncheck the Multimedia Apps tick box for Windows Media in the Applications tab
I still want to remove WM log files etc but NOT the entire contents index !!
I firmly believe that this change should be counted as a bug and reversed
I use Win XP SP3 and I'm not sure what else is affected
