Taken from the article:
Open Regedit
If you are prompted for Administrator password or for a confirmation, type the password or click Allow.
Locate the following registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
In the right pane, click UpperFilters.
Then select Delete.
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, continue:
In the right pane, click LowerFilters.
Then select Delete.
Note: If you do not see the LowerFilters registry entry, unfortunately this contect cannot help you any further.
Go to the "Next Steps" section for information about how you can find more solutions.
Close Regedit.
Reboot your system and check to see if your DVD drive is now present.
Let us know if this helps.
