Is it possible to use AutoHotKey to run PSLoggedOn and edit the output in the stream and return the result?

Question

I am using AutoHotKey to build a simple GUI tool that uses the Sysinternals tool PSLoggedOn. First if I use run psloggedon.exe -l -x \\computername I don't get any output at all.

So I tried run %ComSpec% /C psloggedon.exe -l -x 1> %Temp%\psloggedon.txt and that gives me the output in domain\username format for each user logged in.

Like my first example I would rather just run psloggedon and get the output instead of first opening a command prompt; is that possible somehow?

Either way I want to take the output and avoid writing it to a file, but instead edit the output from the output stream to remove the "domain\" part and then just return the username. How can this be done without any third-party software?

This answer to another question on Serverfault shows a way to do it by reading the StdoutRead. I too was looking at a way to avoid using a file but have decided it's actually the simplest option.
