IIRC, I told you that when you called your Texinfo files *.tex. TeX and Texinfo are different, although related, languages, and you shouldn't mix them. > why we call TeX files but they have the *.txi or *.texi extension > meaning that they really are TeXinfo files ??? Texinfo isn't TeX, it's another language. In particular, the syntax highlighting for TeX and Texinfo is very different. When I load foo.tex into Emacs it automatically enters the TeX mode, which is inappropriate for a Texinfo file. Texinfo is IMPLEMENTED as a set of TeX macros, so when tex.exe sees a Texinfo program, it actually can understand it and typeset it. But for a human, these two look like two entirely different languages.
