Answer 1

Using a Java-COM Bridge , like Jacob. You then select an appropriate COM library, e.g. COM API for WMI to list local users, or any other Windows management information.

The Win32_SystemUsers association WMI class relates a computer system and a user account on that system.

The Win32_Account abstract WMI class contains information about user accounts and group accounts known to the computer system running Windows. User or group names recognized by a Windows NT domain are descendants (or members) of this class.

Working Example (jacob 1.17-M2, javaSE-1.6):

import java.util.Enumeration; import com.jacob.activeX.ActiveXComponent; import com.jacob.com.ComThread; import com.jacob.com.EnumVariant; import com.jacob.com.Variant;  public class ComTst { public static void main(String[] args) {     ComThread.InitMTA();     try {         ActiveXComponent wmi = new ActiveXComponent('winmgmts:\\\\.');         Variant instances = wmi.invoke('InstancesOf', 'Win32_SystemUsers');         Enumeration<Variant> en = new EnumVariant(instances.getDispatch());         while (en.hasMoreElements())         {             ActiveXComponent bb = new ActiveXComponent(en.nextElement().getDispatch());             System.out.println(bb.getPropertyAsString('PartComponent'));         }     } finally {         ComThread.Release();     } } }
