Run SysPrep remotely through commands from Azure powershell

Question

I want to run some commands to do Sysprep remotely through powershell.

So first I created a session using this:

$UserName = "IPAddress\username"
$Password = ConvertTo-SecureString "password" -AsPlainText -Force
$psCred = New-Object System.Management.Automation.PSCredential($UserName, $Password)
$s = New-PSSession -ComputerName IPAddress -Credential $psCred

Then assign the variables used in Sysprep:

$sysprep = 'C:\Windows\System32\Sysprep\Sysprep.exe'
$arg = '/generalize /oobe /shutdown /quiet'
$sysprep += " $arg"

And then finally run this:

Invoke-Command -Session $s -ScriptBlock {$sysprep}

When I run the last command, nothing happens actually.But in the script block, instead of $sysprep, if I give any other command like start/stop a service, it is giving some response. But SysPrep commands doesn't seem to work.Can anyone suggest what am I doing wrong.

You are trying to call for scriptblock object to run while $sysprep is a string. You would want to use Start-Process cmdlet for this. Like so:

$sysprep = 'C:\Windows\System32\Sysprep\Sysprep.exe'
$arg = '/generalize /oobe /shutdown /quiet'
Invoke-Command -Session $s -ScriptBlock {param($sysprep,$arg) Start-Process -FilePath $sysprep -ArgumentList $arg} -ArgumentList $sysprep,$arg
