Windows 7: DVD drives configuration information in the registry damaged (Code 19)

For some reason my Windows 7 Home Premium (32bit) PC is now refusing to operate the DVD ROM and DVD RW Drives. A suspect the latest update to iTunes as they were working fine till the automatic install for that failed. Had to do it manually & that went with some hiccoughs, needing to "Retry" to get it to complete successfully.

The problem is when I try and use a DVD drive you hear it react to the disc, but Autoplay does not run.

Checking in the Device Manager on the General Tab, there is the following message (for both drives)
<< Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged (Code 19) >>

I checked this on the Internet and tried as suggested going to Device manager and Uninstalling both drives. Restarting my PC and letting the "Found New Hardware" re-install them.

Sadly this failed...
Optiarc DVD RW AD-7240S ATA Device Failed
TSST corp DVD-ROM SH-D 162D ATA Device Failed

I then checked whether the driver software for the Device was up to date. It reported that the software for the device is up to date.

Next I ran the Troubleshooter and tried re-installing the driver software which it suggested might fix the problem .... only to be met with <<Device Driver Software not Successfully installed>>
I have also tried running the Microsoft Fix It tool .... MicrosoftFixit.dvd.MATSKB.Run.exe
Still no luck :-( I have attached a file with the details of that report the FixIt tool produced.

I seem to remember the problem iTunes was having was with something like "Matskb"


I am now at my wits end and need expert help, with step by step instructions on how to sort this

This is not a fix but should get you in working order. Do a system restore to a point in time before the iTunes update and see if that doesn't get it sorted for you.

Unfortunately System Restore just throws up a blue screen and will not complete. I have had this issue before .... apparently it is down to Kaspersky Internet Security and the advice from them was such a palava I have not used it. (uninstall Kaspersky before creating a restore point and uninstall Kaspersky before performing a restore)

I have called upon the services of a local expert to come and sit infront of this machine as further investigation showed it would appear that it was something to do with driver filters, which meant doing things in the Registry.

Thankfully he has fixed it for me, which is a great relief ....
