's a bit of an oddity -- a program you didn't know you needed until you have it. It's a sister program to Winpatrol, in case you haven't come across it.
It's probably not for everyone.
I use it to ensure that programs I absolutely rely on to be there when I want them are always there, regardless, but you can also use it to ensure something you never want to run doesn't happen.
It's tiny and reliable, as you'd expect if you're already a Winpatrol user. (You aren't? Why not?)
Just for today, it's $1.99. It's a "per machine" license, which makes sense when you consider what it's for. So I'm buying a second copy.
