Hi
I think you could solve this annoying issue following this short workaround:
- Go to device manager and delete the CD/DVD drive from the device list
- Now start the regedit (registry) and delete the upper and lower filters from the key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4D36E965-E325-11CE-BFC1-08002BE10318}
