Sometimes when you initiate an action like running a downloaded exe file, Vista asks wether you intiated this action and you want to continue, in a pop up window.

Just now, one of these dialogues popped up but I hadn't done anything. It says "User Account Control.....If you started this action, continue etc.etc.

It is identified as {BDB57FF2-79B9-4205-9447-F5FE85F37312}

And below it says, " helps stop unauthorized changes to your computer."

I clicked exit because I thought it was wierd that this would pop up without any preceding action on my part. Anyone know of it or heard of it before?
