I don't know (I don't use the native windows version). However, skipping 
that code when using Python3 the script fails as follows:

python -tt "C:/Program Files/LyX/Resources/scripts/lyxpak.py" "C:/work/"/"a.lyx"
Traceback (most recent call last):
   File "C:\Program Files\LyX\Resources\scripts\lyxpak.py", line 401, in <module>
     main(sys.argv)
   File "C:\Program Files\LyX\Resources\scripts\lyxpak.py", line 302, in main
     input = gzopen(lyxfile)
             ^^^^^^^^^^^^^^^
   File "C:\Program Files\LyX\Resources\scripts\lyxpak.py", line 77, in gzopen
     input = open(file.decode('utf-8'), 'rb')
                  ^^^^^^^^^^^
AttributeError: 'str' object has no attribute 'decode'. Did you mean: 'encode'?


I don't think it was ever tested on Windows with Python3.
