Windows Doesn't See My Optical Drive

Windows stopped recognizing Notpcliterate's CD/DVD drive. The Answer Line forum came to the rescue.

This is a known problem with a known fix. But before you try anything else, be safe and back up your Registry.

Finished? Good. Let's go on.

I

'll give you two ways to correct this problem: an automated fix by Microsoft, and a way to do it yourself.

For the automated repair, go to this page, click the Microsoft Fix it button (pictured here), and follow the prompts.

If that doesn't work, or if you just prefer to know what you're doing, follow these instructions:

1) Close all of your open programs.

2) Select Start•Run, type regedit, and press ENTER.

3) navigate the Registry Editor's left pane as if it was Windows explorer to go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}. Yes, that last folder name is a doozy, but you can find it.)

4) In the right pane, look for any of the four names below. Right-click any you find and select Delete.

*UpperFilters
*LowerFilters
*UpperFilters.bak
*LowerFilters.bak

5) Close the Registry Editor and reboot your computer. Your drive should be back.
