Get the associated file icon for a file
What I want
I am trying to write a function that takes a filename and returns the icon of the application associated with the file type of the file on my system (this is Windows 7).
What i tried
I've seen this question , but the answer doesn't give me the details I need. I'm not very familiar with the ctypes module, and I find the docs on VC ++ functions difficult to follow.
I've seen this question as well , but I'm stuck at the first hurdle. When I try:
import _winreg
_winreg.OpenKey(_winreg.HKEY_CURRENT_USER, 'Software\Microsoft\CurrentVersion\Explorer\FileExts')
Raises WindowsError: [Error 2] The system cannot find the file specified
Even when i do
_winreg.OpenKey(_winreg.HKEY_CURRENT_USER, 'Software\Microsoft')
Which returns a PyHKEY object
, any "key" action I try to do calls aTypeError: The object is not a PyHKEY object

I found the answer here
code from link:
import win32ui
import win32gui
import win32con
import win32api
import cStringIO
import Image
tempDirectory = os.getenv("temp")
ico_x = win32api.GetSystemMetrics(win32con.SM_CXICON)
dst = cStringIO.StringIO()
large, small = win32gui.ExtractIconEx(path,0)
win32gui.DestroyIcon(small[0])
#creating a destination memory DC
hdc = win32ui.CreateDCFromHandle( win32gui.GetDC(0) )
hbmp = win32ui.CreateBitmap()
hbmp.CreateCompatibleBitmap(hdc, ico_x, ico_x)
hdc = hdc.CreateCompatibleDC()
hdc.SelectObject( hbmp )
#draw a icon in it
hdc.DrawIcon( (0,0), large[0] )
win32gui.DestroyIcon(large[0])
#convert picture
hbmp.SaveBitmapFile( hdc, tempDirectory + "\Icontemp.bmp")
im = Image.open(tempDirectory + "\Icontemp.bmp")
im.save(dst, "JPEG")
dst.seek(0)
os.remove(tempDirectory + "\Icontemp.bmp")
return dst.read()
