I almost forget this one, though I have used it for 4-5 years. Win Patrol monitors your system for changes. (and the cute little Scottie dog goes "wurf" to alert you.)

This is a gem! If you update a program, it asks you if you are aware & approve of the update. If you install a program whose *default* is to start up with Windows, it asks you if you approve of that setting. (I 'mostly' do not...I prefer to use certain programs at times of my choosing.)

The main use is to guard against illegal and/or surreptitious installation of programs (malware) that 'some' places try to stick you with.

It monitors the registry and keeps you informed...nice.
