After working well for more than a year, my CD-ROM drive is not seen in Windows Explorer (even after I insert a disc). In Control Panel\Hardware and Sound\Devices and Printers, there is a yellow "!". If I right-click and run Troubleshooter, it tries to reinstall the device driver - but fails (the Troubleshooter report says Completed, but the Notification bubble says Failed to install driver). After trying to reinstall the driver, the Troubleshooter says "CD-ROM Drive has a driver problem" and "Problem with PnP devices - Detected". Under detection details, it says "There is a problem with the driver for CD-ROM Drive. The driver needs to be reinstalled.
Device information. Name: CD-ROM Drive ID: IDE\CDROMMATSHITA_DVD-RAM_UJ892AS________________1.21____\4&A4B6A57&0&0.1.0"
The are no drivers to install when I check for Windows Updates.
I'd be very grateful for advice. Thank you.

This fixed the problem:

Click Start, and then click All Programs.
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 content cannot help you any further.
On the Edit menu, click Delete.
When you are prompted to confirm the deletion, click Yes.
Exit Registry Editor.
Restart the computer.
