We stopped the support of building with all the visual studio versions less
than 2013.
I updated the SDK versions accordingly.

The change in the patch is good.

Yes, that is a good change, I thought of doing the same, but I don't know
how to do it.

The similar change is required for the CreateProject also.

The change is good, but the comment is wrong.

+ # The major visual studio that is supported has nmake

Except for the above two changes, overall the patch is in good shape.
