Can anyone help my with my CD burner... it does not work anymore

The drive that you posted the information for is not capable of burning any CDs. Do you have more than one CD-ROM type drive (they're called optical drives)?

To "uninstall" the drive, you go to Device Manager, locate the drive under DVD/CD-ROM drives, right-click and choose Uninstall.

You need to uninstall the drive that actually burns CDs. It's not the Lite-On DVD-ROM you posted information about, so it must be the other one if you've ever successfully burned disks before.

You're only uninstall the device. You're not uninstalling software. Windows will re-detect the device after you restart. This is part of troubleshooting.
