I lost my DVD/CD-ROM in Vista

I opened Windows Explorer and saw that my DVD drive was lost. Where could have vista hide my DVD. Then I checked Device Drivers and saw a yellow exclamation point beside my DVD drive. I tried to uninstall the driver and checked for newer drivers through the net but none have help. Very stubborn Vista it is. Then began my long day of searching for answer and alas, I came across to a site giving some shed of light to my dismay. It instructed to delete some registry values that is pertaining to the CD-ROM. Below is the registry value that you could use, Just copy the blocked text and paste it to your notepad and save it with a .reg extension.

Windows Registry Editor Version 5.00

;Fixes issues with cdrom drives not working properly
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}]
"UpperFilters"=-
"LowerFilters"=-

To make things easy, I have uploaded the reg file. Go grab them and just double click it..
