Get Identity of my Service Application

Question

I have written following powershell code

$list = Get-SPServiceApplication | ?{$_.DisplayName -eq "AmOwaWordSvcApp"} 
| %{$_.ServiceInstances} | ?{$_.Status -eq "Online"}

For these 2 online isntances of my service application... is it possible to know under which windows identity are these two running?

I did $list[0] | Get-Member but I am not getting anything which gives me the identity name which is running this instance.

Answer 1

The SPServiceApplication you get if you omit your last line has a property ApplicationPool which has a property ProcessAccount
