If you have a good CD burning software, you may want to disable the CD burning capability. There are couple of ways to, do this:

REGISTRY METHOD:

In regedit, navigate to [HKEY_CURRENT_USER\\Software\\Microsoft \\Windows\\CurrentVersion \\Policies\\Explorer]

and look for key "NoCDBurning". You may not find it there if this is your first time. In this case, create a new DWORD key "NoCDBurning" and set its value to disable it.
ALTERNATE METHOD:

Go to your windows explorer and locate the drive that corresponds to CD-RW drive. Right click on it and select properties. Within Properties window, go to Recording tab and you would see and option called "Enable CD Recording on this drive". If it is checked , deselect it.
