I have tried it and it worked fine with me

  • Expand the HKEY_LOCAL_MACHINE key (looks like a folder) by double clicking it (or clicking the "+" next to it.)
  • Expand the SYSTEM Key
  • Expand the CurrentControlSet Key
  • Expand the Control Key
  • Expand the Class Key
  • Please look for a key containing the following string of letter and numbers: {4D36E965-E325-11CE-BFC1-08002BE10318}
  • High light this key by left clicking once on it
  • On the right hand side you are looking for UpperFilters and LowerFilters

    My Cd/DVD burner has disappeared I have tried deleting the upper and lower filters and it still doesn't show up the tray opens the light comes on but it's not usable or found anywhere I have an HP...


    Try this:

    I have to ask, after deleting the upper & lower filters did you reboot the PC?

    If so try this:
    Go to:
    Start>(right click on Computer)left click on Manage.
    Left click on Device Manager
    Locate your DVD/CD-Rom drives.
    Right Click on the DVD/CD Rom-drive> uninstall Now reboot the PC.

    If the drive does not come back in Computer> devices with removeable storage go back to Device Manager (Start>right click computer>Device Manager) to see if you can see DVD/CD Rom-drive.If you dont see the drive in this location then it sounds as if your DVD/CDRom-drive is no longer working and you will have to replace it.

    Good luck!

    Why is my computer not displaying the dvd/cd drive in my computer and not recognizing/reading cd/dvd even after I deleted the upper filter in Device Manager?


    Like Vista, Windows 7 has some issues. That's why corporations, school systems and government entities are still on Windows XP. Only consumers have Vista and Windows 7 for the most part.

    Since you've removed the Upper and Lower Filters, then remove the power cord, remove the battery, turn the laptop over and remove the DvD/CD drive. Open the lid and press and hold the Power Button for 30 seconds. Put everything back in (DvD/CD Drive, Battery, Power Cord) and reboot.

    My dvd/cd drive in not reading or working at all.


    Try and clean the lens of the drive, test again , If the DVD is spinning and trying to read without success then it is possible that the drive is faulty.
    You can recheck using device manager to see the properties of the CD drive , reinstall the driver, if DVD still spins without success then the drive can be the suspect.
