Thanks for the replies guys both seemed plausible but for some reason niether one seemed to be fool proof. The first suggestion didn't appear to work either by the way. Deleting the desk.cpl files and rebooting did the trick nicely. Ofcourse should I need it back again I can always extract the file.

Straight forward, simple, no reg hacks, no software utility to download. Bottom line no display properties available unless you have the CD.
