Hi everyone! I'm having some trouble getting my PowerShell script to work when I save it as a PS1 file. The code runs perfectly fine in the PowerShell window, but it fails to execute as a script. I believe this is due to permissions since I'm trying to modify a registry key. I'm looking for a straightforward way to run this as a PS1 file without having to manually type out the command every time. Here's the code I'm working with:
```
$RegistryPath = "HKLM:SYSTEMCurrentControlSetServicesIntelppm"
$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"
```
When I try to run it, I get this error:
```
Set-ItemProperty : Requested registry access is not allowed.
```
Any suggestions on how to resolve this would be greatly appreciated!

You'll need to run the PS1 script in an elevated PowerShell window since it tries to make changes to the registry. Right-click on PowerShell and select 'Run as Administrator' before executing your script.
You may want to use `Start-Process` to run your script as an administrator. Here’s a quick function that does that:
```powershell
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
}
```
Place your original code in the script section to run it efficiently.
Running the script with `-ExecutionPolicy Bypass` might also help if you face policy restrictions while executing your script.
Consider adding a `#Requires -RunAsAdministrator` statement to your script. It ensures that the script is run with administrative rights, which is necessary for modifying the registry.
Since you're modifying `HKLM`, you always need admin rights. It would be a good idea to check for admin privileges in your script with a try-catch block, so you can handle any permission issues gracefully.
