How do I get the currently-logged username from a Windows service in .NET?

Question

I have a Windows service which need the currently logged username. I tried System.Environment.UserName, Windows identity and Windows form authentication, but all are returning "System" as the user as my service is running in system privileged. Is there a way to get the currently logged in username without changing my service account type?

Answer 1

This is a WMI query to get the user name:

ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT UserName FROM Win32_ComputerSystem"); ManagementObjectCollection collection = searcher.Get(); string username = (string)collection.Cast<ManagementBaseObject>().First()["UserName"]; 

You will need to add System.Management under References manually.
