I never heard about this program till a few days ago. I’ve seen the icon on a few peoples desktop but never new what it did. This program tells you what hotfixes, and /or patches you need to update your pc with, what’s missing and so forth. However there are many programs out there that do similar things, but this program combines it into one program suite. This program is called, Belarc a free program that analyzes your pc and software from top to bottom.  One thing I really loved about this program is it shows you the product keys you used when you installed the software. This can prove invaluable when you have the software installed on a pc, and you need to install it on another pc, but you lost the cd-key, or product key. I’ve included a link and screenshot below.
