Question

I have a Windows service which needs the currently logged username. I tried System.Environment.UserName, Windows identity and Windows form authentication, but all are returning "System" as the user my service is running as has system privileges. 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.
