Question

How to change user credentials of windows service from command line?

Answer 1

I simply called WMI from powershell to do this.

$Svc = Get-WmiObject win32_service -filter "name='ServiceName'"
$Svc.Change($Null, $Null, $Null, $Null, $Null, $Null, "User", "Password")

Don't forget to restart the service afterwards:

Stop-Service -Name 'ServiceName'
Start-Service -Name 'ServiceName'
