Depending on what unit you have, some Pc's dont display your CD-Rom/DvD unless there is a disc in there, As for your D drive it's possible that an external device had the same driver letter and has unallocated that "D" to the drive.. Reboot/complete updates..

Ok... About all the nonsense you just slapped us with...

1. There talking about vista (Completely different Operating Systems)
2. The person with that issue has given the error code: "The driver may be corrupted or missing. (Code 39)".......... Our user has said nothing along the lines of any errors codes...
3. On the extreme off chance that the two operating systems had the same error coeds for that particular issue... there is still no telling that this fix would work for windows 7.. and the fix was due to a reg edit... and the issue was caused by a VISTA update....
4. Your link and this issue are completely different, sorry.

Thanks for this, just came across this problem with win7, I had tried several basic solutions posted elsewhere with no luck. Your regedit solution fixed me right up, Thanks
