Remove Older Vusual Studio Folders

Some times I need to look at an include (.h) file. I only want the one that relates to the latest windows version.

I've convinced myself that I can delete:

C:\Program Files (x86)\Windows Kits\8.0

C:\Program Files (x86)\Windows Kits\8.1

Everything in: 

C:\Program Files (x86)\Windows Kits\10\Include\

     except 10.0.14393.0

1) Do you agree with that?

I'm less sure about the following:

C:\Program Files (x86)\Microsoft SDKs

2) Do you agree that these are replaced with the Window Kits files so they can be delete?

I also have a folder Microsoft Visual Studio 12.0

and

Microsoft Visual Studio 11.0

and

Microsoft Visual Studio

3) I assume these are replaced with Microsoft Visual Studio 14.0 which is the highest I have. Agree?

This 14.0 is confusing since I have Microsoft Visual Studio Enterprise 2015 (version 4.7.02046)

I'd really would like to get rid of unneeded files so I'd appreciate any helpful comments.
