Yeah, there is little information about this because you need a thorough understanding of COM that only comes from experience and research (like coding your own tests and seeing what happens.) There is just about no documentation on the registry entries themselves, so you have to make your own.
You'll also need to research Win32, starting here
Is there anything in VB that will verify the information??
No, there isn't. You have to code all of this yourself, even down to getting the COM information out of target files using Win32 functions.
By writing this yourself, you'are entering uncharted (and barely documented!) territory. This is where the research skills come in.
On top of that, you're not just looking at COM information in the Registry. There's all kinds of stuff in there. But, what your app supports is up to you and your requirements.
