win xp CDBurn on boot

desculpem mas tenho um ficheiro txt com todas as minhas duvidas e outro para dicas escritos em ingles , assim é so fazer copy+paste:

this is some of the many services that i´ve founded out that startup at boot , i´ve already removed theWebCheck and i wonder if i can delete the CDBurn too ; because i´ve thecd burning capabilities disabled in xp and i use ahead software to burn mycds without any problems.
any1 can tell me if this service isreally what i think it is (BuiltInXpBurningSupportService) if so i´ll problaly want to remove it
and the others too if they useless
