A helper function to remove Windows registry key recursively

The default register function of Python(2.6.x) can’t delete a Windows registry key recursively, an exception(Access is denied) will be thrown if you try to delete a key with sub-keys , below is a wrapper which is easy-to-use, you could use it to delete a key and its sub-keys:

import _winreg 

def traverse(root, key, list):
	hKey = _winreg.OpenKey(root, key);

	try:
		i = 0
	    	while 1:
			strFullSubKey = "";
			try:
				strSubKey = _winreg.EnumKey(hKey, i)
				strFullSubKey = key + "\\" + strSubKey;
			except WindowsError:
				hKey.Close();
				return;

			traverse(root, strFullSubKey, list);
			#print strFullSubKey;
			list.append(strFullSubKey);

	        	i += 1
	except	WindowsError:
		print

	hKey.Close();

def reg_delete_key(root, key):
	global list;
	list = list();
	traverse(root, key, list);
	for item in list:
		_winreg.DeleteKey(root, item);
		#print item;

	_winreg.DeleteKey(root, key);

# Example:
reg_delete_key(_winreg.HKEY_CURRENT_USER, r"Software\charry.org");
