If you wanna burn a CD on one of your company's computers, and if that computer has cd-burning disabled, you think: Huh? It's just a checkbox! Well it ain't. They have probably used a reghack which i call cdr_off. This is the reghack that they have prolly used:

Windows Registry Editor
Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"NoCDBurning"=dword:00000001

If you want to ENABLE CD-burning, copy the regcode above into notepad, change the 1 to a 0 and save as cdr_on.reg. Run it and voilá!
