Many people had had this problem with optical devices: when look in MyComputer, the CD and DVD drives missing.
Instead of panic, here are two solutions:
1. Click on Start button ->Run and Type Regedit then press enter.
The Registry editor is opened.
Some words about Windows Registry – this is a place when Windows ‘remembers’ all your settings so when you restart the computer they are exactly as you had set before. This way it remembers your desktop wallpaper, screensaver, screen resolution, taskbar and startmenu settings, mouse speed settings, which programs to run at startup and many many others things you have changed.
But Registry is a place when all the programs and hardware drivers installed write their settings too.
When CD or DVD registry settings are changed or removed by some progtam you have used, Windows cannot guess and do not shows in My Computer.
So if you are in the registry editor, work very carefully and watch not to delete some other program’s registries by mistake.
First, find the following:
HKEY_LOCAL_MACHINE\SYSTEM \CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318} and delete it!
Then open Notepad and copy-paste this text:
REGEDIT4
[HKEY_LOCAL_MACHINE\SYSTEM\ CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}]
“UpperFilters”=-
“LowerFilters”=-
[-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdr4_2K]
[-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdralw2k]
[-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdudf]
[-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UdfReadr]
Then save as CDrepair.reg /be sure you choose ‘all files’ from Notepad dropdown when asked for file name and path./
If file is saved as .reg it has a green icon – this way you can tell it from text file if saved by mistake as .txt
Doubleclick on it . A dialog appears – click OK – because you want to import that values in registry.
That’s all. Restart and if you are lucky the, CD drives will be on their place.
2. If you don’t dare to play with registry, just take this program and run it. It does all that stuff instead you.
And one advice: clicking on unknoun or dubious .reg files is sometimes dangerous. So if you receive them by mail or Skype from strangers, better open first with Notepad to see what exactly are they doing. Otherwice you may harm your computer.
