I am running WinXP Home, SP 3

I have lost the function of my DVD and CD-R drives.

A couple of weeks ago I discovered that my 2 optical drives were not
appearing in "My Computer". Checking the device manager, It showed a "Code 19
error" on both drives.

Searching the Knowledge base on Microsoft.com, I first found instructions to
run regedit as follows:

1) Click Start > Run, type "regedit" (without the quotation marks) and click
2) Locate the following key in the registry:
3) Take a backup of this key and then locate the UpperFilters value if it
4) On the Edit menu, click Delete, and then click OK.
5) Locate the LowerFilters value under the same key in the registry
6) On the Edit menu, click Delete, and then click OK.
7) Quit Registry Editor.
8) Restart your computer.

However, neither upper nor lower filters were present. So I did nothing.

Further searching, and quite by accident, I stumbled across a "Fix-It"
program  on the site, Fixit50027.msi. Running this did in fact restore the
drives to the listing on My Computer. But the drives did not function
properly. Autorun did not function at all. I could play a music disc on the
CD drive by first opening WinAmp and then inserting the disc. But that was

For a time I did not need the drive, and became otherwise distracted.

Now I find the drives do not function. I needed to install some software,
and the discs are not being read. Clicking on the disc in the CD drive in. My
Computer yields nothing. On the DVD drive I get a message to insert a disc,
although the disc is in the drive.

Device manager says the drives are functioning properly.

I am at a loss, and would appreciate any help offered.


(PS: I am sure this will be laughed at, but these problems, and others,
began almost immediately after updating Internet Explorer. I would very much
like to revert to the previous version if anyone knows how to do it.)
