New security toy from Microsoft.

Thanks TM. Yes. I actually tried it on a totally non descript piece of software. But unless something goes wrong, I don't think I'll get too exceited about it.
Very useful for full time software beta testers or new software testers though.

I'm currently using MSE2 for the security purpose..
And it is working good on my laptop with XP OS.
Is this tool really not for home users??
I'm not a professional....

Omarion, This is not a replacement for MSE. This is a tool to look for potential security leaks, such as ports opened on your firewall, or registry changes made when software is installed (at least this is my understanding from what I read - I have not tried it myself).
