THESE two little beauties
" Nice utilities: Mike Lin's Startup Monitor & Startup Control Panel
Today it's the time for two utilities that help me to block unwanted programs, spyware, and so on... that try to register themselves at Windows Startup...
The first (StartupMonitor) runs in background (with a very limited memory and resource occupation) and warns if some program attempts to register itself, allowing you to block it.
The second (Startup Control Panel) adds a program in the Control Panel that allows you to select which program can run and which can't in the already registered programs. Programs can be put in quarantine, and reenabled later...
Congratulations to the author Mike Lin, please check his site for other very nice utilities"
I personally use both of them, as they are a fool proof
