I can't replicate this. I installed pywin32 in a Python 3.8 virtual 
environment, and double-clicked on the venv\Scripts\python.exe in explorer:

Python 3.8.6 (tags/v3.8.6:db45529, Sep 23 2020, 15:52:53) [MSC v.1927 64 
bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
 >>> import os, win32console, win32process
 >>> hwnd = win32console.GetConsoleWindow()
 >>> tid, pid = win32process.GetWindowThreadProcessId(hwnd)
 >>> pid == os.getpid()
False

I tried to find out what happens, using your other code:

 >>> import win32con, win32api
 >>> access = win32con.PROCESS_QUERY_LIMITED_INFORMATION
 >>> hproc = win32api.OpenProcess(access, False, pid)
 >>> executable = win32process.GetModuleFileNameEx(hproc, None)
 >>> print(executable)
C:\Temp\Python\Console\venv\Scripts\python.exe
 >>> hproc = win32api.OpenProcess(access, False, os.getpid())
 >>> win32process.GetModuleFileNameEx(hproc, None)
'C:\\dev\\Python\\Python38\\python.exe'

So, if I understand this correctly, the console is owned by the venv 
Python, but the running process is the installed Python executable. I'm 
lost! How did that latter one get involved?
