self elevating powershell script

Elevate-Script.ps1

$ID = [Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()

If (!($ID.IsInRole("Administrator") -or $ID.IsInRole("Administrators")))
{
    If (Get-CimInstance Win32_OperatingSystem | ? { [UInt32]$_.BuildNumber -ge 6000 })
    {
        Write-Host "Not running as admin, attempting elevation..."
        $Command = $MyInvocation | % { "-File `"{0} {1}`"; Exit" -f $_.MyCommand.Path, $_.UnboundArguments }
        Start-Process PowerShell -Verb Runas -Args $Command
    }
    Else
    {
        Throw "Must run as an administrator."
    }
}

GCIM 6000 有什么特别或必要的，我试过了，这也运行得很好（Windows 10/11），而且它不会忘记当前目录：

$Loc = Get-Location
"Security.Principal.Windows" | % { IEX "( [ $_`Principal ] [$_`Identity ]::GetCurrent() ).IsInRole( 'Administrator' )" } | ? {
    $True | % { $Arguments =  @('-NoProfile','-ExecutionPolicy Bypass','-NoExit','-File',"`"$($MyInvocation.MyCommand.Path)`"","\`"$Loc\`"");
    Start-Process -FilePath PowerShell.exe -Verb RunAs -ArgumentList $Arguments; } }

(Get-Location).ToString()
## Any PS code that needs elevation
Read-Host

With the help of ChatGPT, after numerous attempts, I have managed to write the shortest code for self-elevating PowerShell permissions:

if (-not (net session 2>$null)) { Start-Process powershell -WorkingDirectory "$PSScriptRoot" -ArgumentList "-File `"$PSCommandPath`"" -Verb RunAs; exit }
