Hi Charles,
My name is Igor, I have 12 Microsoft MVP awards. It's a pleasure for me to help others and I'll do all my best to help you. I'm sorry you have a problems.
Microsoft decided to collect all information at docs.microsoft.com site. An information may be created not necessarily by Microsoft technical writers but by GitHub members too.
Msconfig is described at https://docs.microsoft.com/en-us/troubleshoot/w... but this is old version unfortunately.
It is sad but some aspects of Windows components and tools may be undocumented at all. To document all aspects is a really huge task so Microsoft may involve experienced GiHub users.
You may try to find a pieces of information in different blogs but this is really hard and time consuming task.
In fact to get a really full information was a hard task for many years. E.g. some information I could receive only during direct contact with Microsoft employees. It is sad but this is a fact.
Sorry I could not give you a hope but I suppose the naked truth is better than sugar-coated lie.
