How to run powershell script as administrator within the code itself?

_{Saturday, October 29, 2011 4:26 AM}

Hey everyone,

i'm trying to find a way to make my powershell code run as administrator, without right clicking "run as administrator" and without

having to input the user and password manually.

For example, i'd like to run the script with two arguments (user and password) and then the code will use these arguments some how to run

as administrator and let me perform administrative command automatically.

any ideas?

Create a PsSession using your Administrator credentials, then invoke commands in it.

You could save and retrive the credentials details from a secure file (in the sense that cannot directly be read).

To save the admin pass to a file:

$adminPass=Read-Host -AsSecureString

$adminPass|ConvertFrom-SecureString | Out-File "Pass.txt"

To create a cred from the file:

$lala= gc .\Pass.txt | ConvertTo-SecureString

$cred = New-Object System.Management.Automation.PSCredential("Administrator",$lala)

To create the Pssession:

$session= New-PSSession -Credential $cred -ComputerName .

And to invoke commands in that session:

Invoke-Command -ScriptBlock {WhatEverYouWantToRun} -Session ($session)

This will elevate the currently-running script with administrative rights.

Start-Process -FilePath PowerShell.exe -ArgumentList $MyInvocation.MyCommand.Definition -Verb RunAs

Maybe i'm missing something, but this didn't work

added it to my code,

what happened was a pop out window that i had to confirm (asking me to allow powershell to do something) and

then i still got "access is denied" while performing my script.

i do not get access is denied if i run my script from a cmd window that i opened by "run as administrator".

Hi,

If you have enabled UAC I think you can't elevate administrative rights without confirm action in UAC pop up.

One alternative then I found it is create Task in Scheduler and set it to run with highest privileges. But I don’t test it jet.

Or try use Invoke-Command but you need configure remote access event you what do something on localhost.

Invoke-Command -ComputerName localhost -FilePath P:\admin.ps1 –Credential administrator
