There’s a simple registry tweak that can disable the built-in burning features in Explorer, most notably the Burn button on the toolbar that you never ever use.

 

Notice the button is gone after applying the registry hack:

 

Manual Registry Hack

Open regedit.exe through the start menu search or run box and navigate to the following key:

On the right-hand pane create a new 32-bit DWORD value with these properties:

Name: NoCDBurning Value: 1

You’ll have to logout and back in to see the changes. To remove, just delete the key or change the value to 0.

Download Registry Hack

Extract the file and double-click on DisableCDBurning.reg to enter the information into the registry. The EnableCDBurning.reg file will re-enable the burning features.
