get the windows installation drive using python

Question

How to detect the windows installation path or drive using python code ?

Answer 1

>>> import os
>>> os.environ['SYSTEMDRIVE']
'C:'

Answer 2

You can use GetWindowsDirectory via the ctypes library to get the location of the Windows folder, and then you can use os.path.splitdrive to get the drive letter. For example:

import ctypes
import os

kernel32 = ctypes.windll.kernel32
windows_directory = ctypes.create_unicode_buffer(1024)
if kernel32.GetWindowsDirectoryW(windows_directory, 1024) == 0:
    # Handle error
else:
    windows_drive = os.path.splitdrive(windows_directory)[0]
