My DVD/CD rom does not exist according to the device manager



    About a month and a half ago My widows media player stopped playing cds, but would play dvds. Now it won't play either.



    After an hour of tech support with my computer manufacturer, no help whatsoever.  Windows does not even recognize that a dvd/cd rom device exists.  I have tried everything I can short of total restrusting of my computer. Please help.


    By the way this problem started just after a VISTA update downloaded.

  • Hi,


    First please verify your DVD ROM is installed correctly on the computer. I suggest installing it on another computer to check if it can work properly.


    If so, I suggest trying the following methods to troubleshoot the issue.


    Method 1 If you have any third-party CD/DVD-burning software such as Naro or Roxio installed, please temporarily remove them from "Control Panel"-> "Programs and Features".


    Method 2 Delete Filter Drivers


    1. Click Start, type regedit and press ENTER.


    2. Navigate to the following key:




    3. Right click the {4D36E965-E325-11CE-BFC1-08002BE10318} entry, choose "Export", select Desktop in the Save in box and type backup in File Name. Click Save.


    Please Note: The backup file is on the Desktop and named backup.reg. We can simply restore the registry by double-clicking the backup.reg file.


    4. Highlight this key ({4D36E965-E325-11CE-BFC1-08002BE10318}), on the right pane, and then check if Upperfilters and Lowerfilters value are present. If so, please right click on the values and select "Delete" to remove them.


    5. Restart the computer


    If the issue persists, as you mentioned that the issue began to occur after an update was installed, I suggest uninstalling the update or performing a System Restore to restore the system to a state before the issue occurred to check the result.


    Hope it helps.
