The DVD disc drive icon has dissapeared from my computer.

Try first disconnecting power cable for ten minutes, if computer is a laptop also remove the battery at the same time. This will

If there is a disk inside the DVD drive, remove the disk.

Try doing a system restore, here you get instructions for XP, Vista is similar: How to perform System Restore on Windows...

If all this does not work open the BIOS setting menu at startup and check if the DVD is detected.

In BIOS also ensure that the optical driver is not manually disabled, and that SATA port (if using serial ATA DVD) or PATA channel (if using IDE) is not disabled.

If DVD is not detected in Bios, and the DVD and/or PATA/SATA channel/port are not disabled, then you need to replace the DVD drive unit.
In that case check the DVD drive data and power connection. Eventually try extracting the DVD drive and putting it back in place.

IF DVD is detected in bios, then the problem is a corrupted Windows registry.

In that case go to Start menu, open the Run dialog box, and type Regedit in the Run box.

The registry editor will open.

lick the Start button, press run and type regedit.


Before doing the procedure, save a copy of the registry. Click File, then Export using the menu at the top of the Registry Editor Window:


  1. In the Registry Editor window open the HKEY_LOCAL_MACHINE folder.
  2. In the HKEY_LOCAL_MACHINE folder, open System.
  3. In System open CurrentControlSet folder
  4. Open Control folder.
  5. Open Class folder.
  6. In the Class folder open the folder {4D36E965-E325-11CE-BFC1-08002BE10318} .
  7. In the right panel click to select UpperFilters registry entry.
  8. Delete the UpperFilters registry entry from folder .
  9. Click Yes when asked to confirm delete.
  10. In the right panel select LowerFilters.
  11. Delete LowerFilters registry entry.
  12. Click Yes when asked to confirm delete.
  13. Close Regedit.
  14. Restart the computer.

How to jump to a registry key directly ?

When you start Regedit, it automatically opens the last key that was viewed. (Registry Editor in Windows XP saves the last viewed registry key in a separate location). If you wish to jump to a particular registry key directly without navigating the paths manually, you may use any of these methods / tools.

Option 1 Using a VBScript: Copy these lines to a Notepad document as save as registry.vbs
'Launches Registry Editor with the chosen branch open automatically
'Author : Ramesh Srinivasan

Set WshShell = CreateObject("WScript.Shell")
Dim MyKey
MyKey = Inputbox("Type the Registry path")
MyKey = "My Computer\" & MyKey
WshShell.RegWrite "HKCU\Software\Microsoft\Windows\CurrentVersion\Applets\Regedit\Lastkey",MyKey,"REG_SZ"
WshShell.Run "regedit", 1,True
Set WshShell = Nothing

Double-click Registry.vbs and then type the full registry path which you want to open. [ Example: HKEY_CLASSES_ROOT\.MP3 ]

Limitation: The above method does not help if Regedit is already open.
