   FWIW, the following method do works for me:

   import sys
   
   if sys.platform == 'win32':
       import os
       import winreg
       def get_git_binary_path():
           proc_arch = os.getenv('PROCESSOR_ARCHITECTURE', '').lower()
           proc_arch64 = os.getenv('PROCESSOR_ARCHITEW6432','').lower()
   
           if proc_arch == 'x86' and not proc_arch64:
               arch_keys = {0}
           elif proc_arch == 'x86' or proc_arch == 'amd64':
               arch_keys = {winreg.KEY_WOW64_32KEY, winreg.KEY_WOW64_64KEY}
           else:
               raise Exception("Unhandled arch: %s" % proc_arch)
   
           for arch_key in arch_keys:
               for base_key in [winreg.HKEY_LOCAL_MACHINE, winreg.HKEY_CURRENT_USER]:
                   try:
                       with winreg.OpenKey(
                               base_key, r"Software\GitForWindows",
                               0, winreg.KEY_READ | arch_key) as key:
                           path = winreg.QueryValueEx(key, 'InstallPath')[0]
                           git_path = os.path.join(path, 'bin', 'git.exe')
                           if os.path.exists(git_path):
                               return git_path
                   except FileNotFoundError:
                       continue
           return None
   else:
       # on normal platforms, git is just in the PATH
       def get_git_binary_path():
           return 'git'

   @tardyp thanks a lot for the suggestion and the research!
   If you could provide the code above in a PR I would happily merge it.
