Thanks for replying, Neemobeer. What I'm trying to do, is: stop unnecessary services, turn automatically starting services in services that start on demand, etc. Several guides about how to do this are around, e.g. Black Viper's and Techlick's, but I like to understand what I'm doing, not just blindly follow what someone else has thought out for their situation; mine may be different.
Regards, Jaap.
