correct cd/dvd registry

sorry, don't know what else to say, I've never seen the error before. Tried to reinstall, gives same error, code 31 'registry corrupted', tried to fix using regedit.

a bit more info please.

where exactly in device manager are you seeing this message and what problem(s) are you getting?

properties for phillips dvd/cd drive in device manager, says,

Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)

ok, you will need to do this:

Go to start> run and type in "regedit" (without the quotes) then press ok.

1) Remove the Upperfilters and Lowerfilters values by:

a) Expand the "HKEY_LOCAL_MACHINE" key (looks like a folder) by double clicking it.

b) Expand the "SYSTEM" Key

c) Expand the "CurrentControlSet" Key

d) Expand the "Control" Key

e) Expand the "Class" Key

f) Carefully look for a key containing the following string of letter and numbers:

{4D36E965-E325-11CE-BFC1-08002BE10318}.

(The full path is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318} )


g) Highlight this key by left clicking once on it

h) On the right hand side you are looking for "Upperfilters" and "Lowerfilters", once you find these delete them by high lighting (left clicking on them once) and then right clicking on them and choosing "delete"

NB only one key may be present but still delete it.

Now reboot and your optical drive(s) should function again.

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.

thanks bacillus, i just had the same problem and fixed it with this posting.
