Limewire are all "trouble."
Let's not worry about iTunes and just use Microsoft's fix at http://support.microsoft.com/kb/314060
Since this machine's owner is running Limewire we know that it's a trouble machine so be sure to tell them it may never be fixed but a reload of the OS may be needed.
Sorry this post is long, but I have been working on this for weeks. I have been down several dead ends.
Computer: Dell Dimension 4550 P4 2.53 GHz 384 Mb RAM. Windows XP Home SP3
Machine had Easy CD creator (Roxio) installed and iTunes (I don?t know which version this was. I don?t know if iTunes was updated in the previous 3-4 weeks, but I believe it was to iTunes 8, possibly 8.02. )
Running McAfee SecurityCenter and Spybot S&D resident.
Running ATI Catalyst software for the video card, VisionTek Radeon 9600
Running Limewire 4.16.6.
Machine picked up a copy of $sys$DRMserver.exe from a copy protected disk.
First indication of trouble: My daughter tried to play a new music CD in the CD-RW drive. It didn?t play, but it would play in her boom box, so I didn?t pay any attention. This was 3-4 weeks back. I figured it was more DRM crud.
Second indication of trouble: She tried to download a song, but it was caught as malware and McAfee prevented her from downloading it.
The other night, she went to play a game using a CD. This game CD has worked in the past, but would not. I asked her to restart the machine, which she did, but it did not clear up the problem.
Discovered both drives have disappeared from My Computer. Checked the Device Manager, they both show up as Code 19, your registry may be damaged.
Tried uninstalling both drives, then restarting the machine. No good. Tried the troubleshooter that comes up after the drives fail to install correctly, without positive result.
Tried uninstalling the drives then rebooting the computer several times.
Uninstalled Easy CD Creator using add/remove programs as directed by 314060.
Used the Microsoft knowledge base article on code 19 errors, article [Q314060].
Used the ?guided help? software, which completed successfully. Did not uninstall iTunes. [Is this a possible problem?]
Tried uninstalling the drives then rebooting the computer several more times.
Tried unplugging the power to the two drives, restarting, shutting the system down, then plugging them back in?no change, still code 19.
Tried uninstalling iTunes (much protesting about losing her music.) I uninstalled the drives several times, all ending in code 19 when the ?new? hardware was recognized.
Uninstalled Spybot S&D. Ran McAfee virtual technician on Security Center, which found and repaired 3 errors.
Downloaded and Installed iTunes 8.0.2 so as to not lose her music.
Regedit shows the upper filters have returned in the class for CD/DVD. ?GEARaspiWDM? is the upper filter.
Googled GEARaspiWDM. Appears to be installed by iTunes, and appears to have issues when ATI Catalyst is running, per posting on zdnet.
Checked that the upper filters were still present in the registry (it was)
Ran the ?guided help? software from Q314060; which ran OK. Uninstalled the drives, then restarted the computer. No joy.
Checked the registry. Upper filter was still in place, apparently not removed by the ?guided help? software. Removed the filter manually. Uninstalled the drives, Restarted the machine, no positive result.
iTunes protests that the drivers for burning to CD are missing.
Tried to run the CD diagnostics from inside iTunes?there were no drives in the drop down, apparently they are still invisible. I could not run the diagnostic.
Downloaded, ran the CDGONE patch from post on CNET: Look and try CDGONE at http://www.aumha.org/regfiles.php
Created restore point. I had to extract the patch from the zip file before I could merge it!
Merged the registry patch OK. Restarted the machine, still no drives, still code 19 registry may be damaged.
Created the UpperFilter GEARAspiWDM from scratch. iTunes no longer protests that it needs re-installed. Both drives are still code 19.
