Error 19 on dvd rom drive in windows

One of my clients had a dvd rom drive suddenly start to fail in Windows XP. Device Manager had the error message “information in the registry is incomplete or damaged (Code 19)” Acer’s website didn’t even have a driver for the cdrom so it was off to google. A lot of results for code 19 and cdrom drivers, but the results at Toshiba’s forums provided the answer – delete (or rename) HKLM \ system \ currentcontrolset \ control \ class \ {4D36E965-E325-11CE-BFC1-08002BE10318} \ UpperFilters and LowerFilters and then reboot.
Ironic that I had to use Toshiba’s support for an Acer problem!

    I had the exact same problem with a Pioneer DVD on my Acer Aspire 1710. I searched as you did to no avail.

    I’m not sure how I found you, but I did after Googling and I can’t thank you enough for recording the information. The correction worked perfectly and I’m back in business. It had been many years since I edited in the registry and it was like doing open heart surgery after a night at the Holiday Inn. It worked. I just deleted the two filter files, then rebooted and it was corrected.

    By the way I had tried to reset my XP to an earlier time and that would not work. I was desperate.

    Thank You,
