Thanks, now I can confirm that your emacs thinks that it's running on
linux.

OK. (More precisely, "Type ... compilation" isn't a request, so you
don't have to obey it. It's just an informative message to tell that
"you can do this".)

That isn't an error. It indicates that AUCTeX did (try to) start
typeset. Under normal circumstances, it's followed by log message from
running pdflatex process like this:
----------------------------------------------------------------------
Running `LaTeX' on `abc' with ``pdflatex  -file-line-error    
-interaction=nonstopmode abc.tex''
This is pdfTeX, Version 3.141592653-2.6-1.40.24 (TeX Live 2022) (preloaded 
format=pdflatex)
 restricted \write18 enabled.
...

We have to find out the reason why log output didn't appear.
1. Was helloworld.pdf generated after the above procedure? If so,
   pdflatex process did run successfully while emacs just fails to
   capture its output.
2. After AUCTeX is loaded, insert
(start-process "dummy" (current-buffer) TeX-shell TeX-shell-command-option "ls")
   at last of *scratch* buffer and type C-x C-e just after the closing
   ")". What appears in the buffer?
3. Try
(start-process "dummy" (current-buffer) TeX-shell TeX-shell-command-option 
"tex.exe --version")
   in the same manner and report the result.

By the way, if you need other binaries in TeX Live, e.g. bibtex,
makeindex etc., you have to modify the respective entries in
`TeX-command-list' to add ".exe" suffix like this:

> ("BibTeX" "bibtex %(O?aux)" TeX-run-BibTeX nil

("BibTeX" "bibtex.exe %(O?aux)" TeX-run-BibTeX nil
                 ^^^^

Use `M-x customize-option TeX-command-list RET' to do that.
