How to fix Code 39 error
with DVD/CD-ROM drives in Windows XP or Vista
I was fixing a computer the other day and ran across the following error in Device Manager on the CD-ROM drive.
"Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)"
Because of this error, the drive did not show up in My Computer and the customer was unable to burn CDs or read any CDs.
I uninstalled the drive from Device Manager, rebooted the computer, and the problem remained, so obviously it appeared to be a registry issue that I would have to solve. If you are receiving this Code 39 error and your CD or DVD drive is missing and has a yellow exclamation mark in Device Manager, I hope this information is useful.
To solve this Code 39 error, follow these instructions:NOTE:
After removing these registry keys
and rebooting, it may be necessary to reinstall any CD or DVD recording applications.
1) Close all open programs
2) Click on Start, Run, and type REGEDIT and press Enter
3) Click on the plus signs (+) next to the following folders
4) This folder is the DVD/CD-ROM Drive Class Description in the registry. Look for any of the following names in the right hand column.
5) If any of the above keys shown in step 4 are listed, right-click on them and choose Delete
6) After deleting the keys, close the Registry Editor
7) Reboot your computer
8) Open My Computer and check to see if your CD or DVD drives have returned. You may also want to open Device Manager and verify that the yellow exclamation and error code on the CD or DVD drive is gone.

Microsoft surprised more than a few people on Thursday when one of its developers told a technical crowd in Australia
that 32-bit versions of Windows Vista won't be able to play back next-generation high-definition protected content, i.e. commercial Blu-ray and HD DVD discs.
Later Thursday, representatives in the U.S. said that senior program manager Steve Riley was mistaken.
"The information he provided to that audience was incorrect," a representative told CNET News.com. "Playback is possible with Windows Vista in 32-bit."
The decision of whether to offer that support, the representative said, won't be made by Microsoft but rather by the third-party software makers that create DVD playback software, folks like CyberLink
"It is up to the ISVs providing playback solutions to determine whether the intended playback environment, including environments with a 32-bit CPU, meets the performance requirements to allow high-definition playback while supporting the guidelines set forth by the content owners," Microsoft PR manager Adam Anderson said in a statement. "No version of Windows Vista will make a determination as to whether any given piece of content should play back or not."
