C# WMI Howto List Windows OS User List With Login Names

It is not easy to reach windows login users list in C#.

There are several ways to get this list, like WMI (windows media instrumentation).
But here I will use a different way, let's read the registry and list the win user list.

string users_reg_key=
@"SOFTWAREMicrosoftWindowsCurrentVersionExplorerDocFolderPaths";

With using this registry key, we can have all users who login into that os. Let's write a simple function to read this registry key in C#.

 public string[] ListWinUsersList()
{
//The registry key for reading user list.

RegistryKey key =
Registry.LocalMachine.OpenSubKey(users_reg_key, true);

string[] winusers;

if (key != null && key.ValueCount > 0)
{
winusers = key.GetValueNames();
}
return winusers[];
}

And now we get a string array filled with windows users list.
