Hello,

OS Win XP Pro, HP Pavilion, PIII 550MHz, 192 MB RAM, 41% free on 27.9GB HD

Have a system that has had its C: drive changed from FAT32 to NTFS and then defraged. The CD-RW drive is now not recognized. The Device Manager properties for it says 'Windows cannot start this hardware device because its configuration Information (in the registry) is incomplete or damaged (Code 19)'. I located the corrupt entry in the registry but cannot do anything with it. Can't even uninstall and reinstall or update driver. Regedit cannot even do anything to the entry - it fails trying. Restore points don't work because of the file structure change. I would be happy to supply any info you may need if necessary! I'm obviously not a registry expert and would truly appreciate any input, direction, etc. Thank You.

Found the resolution!! If you have taken your time to look at this problem, I thank you sincerely! The following is quoted from the MS Knowledgebase. . .
*********
1. Start Registry Editor (Regedt32.exe).
2. Locate the UpperFilters value under the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
3. On the Edit menu, click Delete, and then click OK.
4. Locate the LowerFilters value under the same key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
5. On the Edit menu, click Delete, and then click OK.
6. Quit Registry Editor.NOTE: After you remove the Upperfilters value and the Lowerfilters value, if you notice lost functionality in a particular program, such as CD recording software, you may need to reinstall that software. If the problem recurs, consult with the software vendor for assistance.
7. Restart your computer.
