1. System Restore to when it worked.
2. My method which I use without any reserve but you may have a reason (do tell why?) is to boot SAFE MODE and to remove all CDRW units you find in the DEVICE MANAGER. On a normal reboot, Windows redetects and I find this to be an easy fix.
Have CD-RW which will not auto run when inserting a disk. Error message says that I'm trying to open a .db file and Windows does not recognize the extension offering to go to the Internet for identification or Select from a list.
How do I correct this without reinstalling the software or hardware?
