Q. Help, my CD drive or DVD drive is missing?
A. I am taking this to mean your CD/DVD drive is not recognized, so you can’t play a CD or DVD.
You probably have either corrupted or deleted Windows registry entries. To solve this problem, you need to use the Registry Editor. ***Note: By using Registry Editor, you are modifying the registry. Serious problems might occur if you modify the registry incorrectly. Make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. For more information about how to back up and restore the registry, click here to read the article in the Microsoft Knowledge Base.
Make sure you are logged into your computer as a administrator.
- Click Start
- Click Accessories, and then click Run.
- Type regedit, and then click OK. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
- In the navigation pane, locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
- In the right pane, click UpperFilters.
*Note – You may also see an UpperFilters.bak registry entry. You do not have to remove that entry. Click UpperFilters only. If you do not see the UpperFilters registry entry, you still might have to remove the LowerFilters registry entry. To do this, go to step 8. - On the Edit menu, click Delete.
- When you are prompted to confirm the deletion, click Yes.
- In the right pane, click LowerFilters.
*Note – If you do not see the LowerFilters registry entry, unfortunately this you will need to contact Microsoft for additional support. - On the Edit menu, click Delete.
- When you are prompted to confirm the deletion, click Yes.
- Exit Registry Editor.
- Restart the computer.
- Click Start button, click Computer, and then see whether the drive is listed.
If you can’t play or access a CD or DVD, you might have to reinstall some programs. Some programs might not be able to use your CD or DVD drive until you reinstall those programs. If the problem occurs again when you install or uninstall those programs, check to see if the manufacturer of the program has an update available. Some examples of programs that might be affected are:
- iTunes software by Apple
- Nero software by Nero Inc
- Roxio Creator software by Sonic Solutions
- Zune software by Microsoft
