Ok, I have 16 automatic and 2 manual services now. Thanks man. But the holiday is comming, can not you give me a break, please. I do not like services at Manual, only those, which will start & then stop. I need Network Connections to see and set up my IP assigned by DHCP. WMI could be disabled, but it is not worthy of all troubles, that would follow. It is mentioned, that Application Experience is needed by Aero, in the first post of this thread as well, but who knows, I will try to keep it off. I have disabled SAM, because I guess, that it can actually decrease security, since it could allow "bad" services to be started. I have also disabled Event Log and Protected storage, but this little devil will most likely start anyway, I have no idea, why it does that. For those, who do not understand, why I tweak services. It is not becauce of performance, that is just the second product, the main reason is the security. I have not played any games for 2 years, so I do not care, if the memory footprint is 200 MB or 400 MB. The point is, that if the service is disabled, it can not be exploited (itself, its files still can). Talking about XP, there was at least one vulnerability for almost every service, including DHCP, Network connections and etc. I expect the same with Vista and since the number of my security aplications is zero, I just have to find another way to secure my PC. Any ideas are wellcome.
