DVD Drive is not recognized by Windows 7

[Mr.ken]

One of my Windows 7 computer at office is not recognizing the DVD drive. The devices is listed in the device manager with a yellow exclamation mark displaying that there were problems with digital signings. I think Windows cannot verify the digital signature for the drivers required for this device. so I disabled Digital Signing requirement, and it saw my DVD drive, then failed to install drivers for it saying the Device was Unplugged.

How can i fix this problem ?
Please help.

That can be the cause of a recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. To solve this problem , just go through this steps:-

1. Go to Start > type regedit > press enter.

2. Open the Registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

3. In the right pane, right-click UpperFilters, and then click Delete.

4. Click Yes to confirm the removal of the UpperFilters registry entry.

5. In the right pane, right-click LowerFilters, and then click Delete.

6. Click Yes to confirm the removal of the LowerFilters registry entry.

7. Exit Registry Editor, and then restart the computer. After you remove the UpperFilters registry entry and the LowerFilters registry entry, you may lose functionality in certain programs such as CD recording programs. I

n this scenario, you must reinstall any affected programs. If the problem recurs, contact the program vendor to determine whether an update is available for the program.


Hope this will fix the problem

This is really a strange problem. You can try this as well to fix the problem:-

• Click on Start -> All Programs -> Accessories -> Right click Command Prompt -> Run as administrator.
  
• Paste the following line and hit enter afterwards

bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS

This should solve the problem of DVD drives not being recognized in Windows 7.
