You’re right, there’s no ‘ServiceAccount’ property. For some reason MS has obscured it under the name of ‘StartName’.

Here’s how I do it:

$servers = ‘Server1’, ‘Server2’

$servers | ForEach { Get-WMIObject Win32_Service -computer $_ | Where-Object { $_.Name -like ‘MSSQL*’ } | Select SystemName, Name, @{Name=”ServiceAccount”;Expression={$_.StartName}} }
