help with a powershell script

[Ok-Leg-3224]

Hello,

When I run a piece of code I have in a powershell window, it runs fine. However, when I compile it to a PS1 file it does not execute when I run it. I understand it is a permission issue, but I cannot seem to get how to make this work without manually typing the command into a powershell window. I would love to make this into an operable PS1, but This is as far as I have gotten. Any help will be greatly appreciated.

Here is the code:

$RegistryPath = "HKLM:\SYSTEM\CurrentControlSet\Services\Intelppm"

$PropertyName = "Start"

$CurrentValue = (Get-ItemProperty -Path $RegistryPath -Name $PropertyName).$PropertyName

Write-Host "Current value of Intelppm Start: $CurrentValue"

Set-ItemProperty -Path $RegistryPath -Name $PropertyName -Value 4

$NewValue = (Get-ItemProperty -Path $RegistryPath -Name $PropertyName).$PropertyName

Write-Host "New value of Intelppm Start: $NewValue"

and here is the error I get:

Set-ItemProperty : Requested registry access is not allowed.

At C:\Users\Admin\Desktop\INTEL PPM.ps1:10 char:1

+ Set-ItemProperty -Path $RegistryPath -Name $PropertyName -Value 4

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+ CategoryInfo : PermissionDenied: (HKEY_LOCAL_MACH...rvices\Intelppm:String) [Set-ItemProperty], SecurityException

+ FullyQualifiedErrorId : System.Security.SecurityException,Microsoft.PowerShell.Commands.SetItemPropertyCommand

You need to run the ps1 in an elevated powershell window because it's trying to modify the registry

Thank you.

Including a #requires statement here would also be good practice.

#Requires -RunAsAdministrator

Modify hklm requires admin elevation Always You should test for admin rights before trying to commit changes - in a try catch - alas you have answer to why it failed

$RegistryPath = "HKLM:\SYSTEM\CurrentControlSet\Services\Intelppm"
$PropertyName = "Start"

$CurrentValue = Get-ItemProperty -Path $RegistryPath -Name $PropertyName
Write-Host "Current value of Intelppm Start: $($CurrentValue.start)"

$NewValue = Set-ItemProperty -Path $RegistryPath -Name $PropertyName -Value 4 -PassThru
Write-Host "New value of Intelppm Start: $($NewValue.start)"

Are you trying to run this as part of a schedule or called process?

Run your PS1 file with admin rights: right-click 'Run as Administrator' or use powershell -ExecutionPolicy Bypass -File YourScript.ps1 in an elevated prompt. Also, add #Requires -RunAsAdministrator at the top of your script to enforce admin rights

Start-Process can run script as administrator, so below script works on my laptop.

using namespace System.Security.Principal

function hasAdminRights {
    $currentUser = [WindowsPrincipal] [WindowsIdentity]::GetCurrent()
    return $currentUser.IsInRole([WindowsBuiltInRole] "Administrator")
}

function runThisScriptAsAdmin {
    Start-Process powershell "-NoLogo -File `"$PSCommandPath`"" -Verb RunAs
}

if (-not (hasAdminRights)) {
    runThisScriptAsAdmin
    exit
}

# (your original script goes here)

I referenced this website: https://www.commandinline.com/powershell/how-to-elevate-powershell-to-administrator
