How can I run a command window hidden or minimised?

Question

I have written a powershell script which generates a "EULA" type popup which the user has to agree to.

It does this at logon by running as a scheduled task for a user (non-admin) account. It needs to run elevated, so I am using the following script to run it elevated:

$pw= convertto-securestring "myPassw0rd" -asplaintext –force $credential = new-object -typename system.management.automation.pscredential -argumentlist "-default-",$pw $localArgs = "/c Powershell c:\scripts\myScript.ps1" [System.Diagnostics.Process]::Start("cmd.exe", $localArgs, "Administrator", $credential.Password, $computer) 

(I will be encrypting the password to make it slightly more secure, but that's not relevant to this question.)

Anyway - my problem is that when the script is called it displays the command prompt window behind my "pretty" EULA popup.

Is there a way to hide / minimise the command window?

Thanks,

Ben

Answer 1

This should be what you need:

$Process = new-Object System.Diagnostics.Process $Process.StartInfo.UserName="Administrator" $Process.StartInfo.Password=$Credential.Password $Process.StartInfo.Domain="$Computer" $Process.StartInfo.WindowStyle="Hidden" $Process.StartInfo.FileName="cmd.exe" $Process.StartInfo.Arguments="$localArgs" $Process.Start() 

Answer 2

You can use the Start-Process cmdlet (PowerShell 2.0):

Start-Process cmd.exe -Credential $credential -WindowStyle Hidden -WorkingDirectory ... -ArgumentList...

Answer 3

You can't use -Credential and -WindowStyle parameters together with PowerShell v2, you either need PowerShell v3 or use -NoNewWindow and -Credential parameters together

You can use the below code for PowerShell v2:

$user = "{user}" $pass = ConvertTo-SecureString -String "{password}" -AsPlainText -Force $cred = new-object -typename System.Management.Automation.PSCredential ` -argumentlist $user, $pass start-process -Credential $cred -NoNewWindow powershell "-command & '{path and script}'"
