I'am trying to edit/configure a proxy server using python on windows using below code. But i get an error. Need help !!

import winreg

INTERNET_SETTINGS = winreg.OpenKey(winreg.HKEY_CURRENT_USER,
    r'Software\Microsoft\Windows\CurrentVersion\Internet Settings',
    0, winreg.KEY_ALL_ACCESS)

def set_key(name, value):
    _, reg_type = winreg.QueryValueEx(INTERNET_SETTINGS, name)

You are getting the error because you are trying to query for a key that does not exist yet. You need to create the key in your registry. Setting the value direclty also creates the key.

INTERNET_SETTINGS = winreg.OpenKey(winreg.HKEY_CURRENT_USER,
r'Software\Microsoft\Windows\CurrentVersion\Internet Settings',
0, winreg.KEY_ALL_ACCESS)

winreg.SetValueEx(INTERNET_SETTINGS, "ProxyServer", 0, winreg.REG_SZ, "your server address")
