How do you disable the included burning engine?
Rightclick your burner's icon in Windows Explorer and choose "properties". There you will find a tab on which you can enable/disable the embedded Roxio burning engine. This just makes the burning engine to start manually, e.g. when a program needs this utility.
To completely disable it, you have to spot the IMAPI system service under Administrative tools and set it from manual to disabled.
Here is the path...>Control panel >Administrative Tools >Component services >Local services >Imapi, double click >on the general tab >startup type, choose disabled >apply. Reboot computer. Now you can install your favorite CDR proggies without WinXP's imbedded burning engine nuking your software.
Also don't install the CDRW update from Windows Update. If you did, uninstall it through the add/remove programs menu first. Then disable per above instructions.
