hoe to prevent any program from starting inspite of we double clicking on it using the registry?

recently i had this trouble where memeory was being dumped every time the computer booted.

on checking i realized an exe dump(0-k) being executed every time the

computer booted after which obviously the memory got dumped onto the

screen following which the computer reboots.

on checking msconfig the exe had created a slot for itself to run

during startup.to prevent this process from running again i disable it

in msconfig and i also deleted the key from the registry for

msconfig\startup.inspite of doing all this every time the system boots

dump.exe gets executed although i had deleted it and a slot for it

would be created in msconfig and it would be enabled.actually i could

have uninstalled it if was a program but its a system program which is

present in system32.

1.Now is there any i can edit the windows registry such that i can

disable a process or an exe from executing at strartup or any other

time we try to run it
