The first link is not of use to me beause I am unable to see System.Management.ConnectionOptions class in my intellisense and the second link is also not useful because I am unable to see 'ManagementScope' class. — user1451111, Mar 24 '14 at 13:30
I have tried all the available answers from this site but all of them end up with the following exception, "RPC server is unavailable". Where I can successfully log on them using remote desktop viewer. — user1451111, Mar 25 '14 at 11:52

This query give to you all the logged users

ManagementObjectSearcher query= new ManagementObjectSearcher("SELECT * FROM Win32_UserProfile WHERE Loaded = True");

You also have other parameters like LastUseTime into Win32_UserProfile

This is used for local computer. Can I use it somehow for remote machines? – user1451111 Mar 25 '14 at 07:11
All classes in the System.Management namespace work with single or multiple computers in a domain. You need to use the proper constructor that specifies *where* to search (local, remote computer, multiple computers) etc. – Panagiotis Kanavos May 27 '14 at 07:14

This is not reliable. Sometimes it returns users that are not logged in. – Lance Sep 13 '21 at 19:01
