If your CD/DVD/BD drive is not working, and its status is listed as “Code 41″ in device manager, there is a good chance a simple registry edit can fix the issue. Here is what you need to do:


Manual fix:

  1. Go to your Start menu and click “Run…”
  2. In the Run box that opens, type “regedit” and press Enter.
  3. In the new window that opens, navigate the tree in the left pane until you are at:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
    Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
  4. In the right pane of the window, you should see an “UpperFilters” key.
  5. Right-click the “UpperFilters” key an select “Delete”. Respond “Yes” to the confirmation prompt.
  6. You should also see a “LowerFilters” key in the right pane.
  7. Delete the “LowerFilters” key.
  8. Restart your computer.

    Thought I should mention to people, who may have stumbled onto this page due to a code 41 error with their keyboard, that your Code 39 keyboard fix also fixed my keyboard code 41. Excellent work!!

    Ryan, you are a genius. When my CD/DVD ROM drive stopped working I ran device manager. It suggested that I contact the mfg. so I sent an E-mail to HP. They advised that I should purchase a new drive from them. Before spending $200 I decided to google the error message to see if anyone ever had this problem and I came across your web site. Ten minutes later my PC was fixed and the CD/DVD ROM drive was again operational. Please accept my donation with much gratitude.

    The code 41 tip was the solution to my problem…Thanks. Your advice saved me a gross amount of time, I had already spent 3+ hours trying to resolve the error.

    I had an error code 41 problem with my keyboard and, although your instructions for fixing the error code 41 did not work, your instructions for fixing the keyboard error code 39 worked !! Thank you and I hope you have a prosperous New Year.
