How to create a Run As Administrator shortcut using Powershell

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This answer is a PowerShell translation of an excellent answer to this question How can I use JScript to create a shortcut that uses "Run as Administrator".

In short, you need to read the .lnk file in as an array of bytes. Locate byte 21 (0x15) and change bit 6 (0x20) to 1. This is the RunAsAdministrator flag. Then you write you byte array back into the .lnk file.

In your code this would look like this:

 

$WshShell = New-Object -comObject WScript.Shell
$Shortcut = $WshShell.CreateShortcut("$Home\Desktop\ColorPix.lnk")
$Shortcut.TargetPath = "C:\Program Files (x86)\ColorPix\ColorPix.exe"
$Shortcut.Save()

$bytes = [System.IO.File]::ReadAllBytes("$Home\Desktop\ColorPix.lnk")
$bytes[0x15] = $bytes[0x15] -bor 0x20 #set byte 21 (0x15) bit 6 (0x20) ON
[System.IO.File]::WriteAllBytes("$Home\Desktop\ColorPix.lnk", $bytes)

If anybody want to change something else in a .LNK file you can refer to official Microsoft documentation.

我们的 powershell 创建 set-shortcut 脚本
# http://poshcode.org/906
Function Set-ShortCut([string]$SourceExe, [string]$TargetFileName='', [string]$Arguments='', [string]$WindowStyle='Normal')
{
    If( (Test-Path $SourceExe) -eq $false)
    {
        Error "$SourceExe doesn't exist";
        return
    }
    Info("Creating desktop shortcut for $SourceExe");
    $WshShell = New-Object -comObject WScript.Shell
    $BaseName = [System.IO.Path]::GetFileNameWithoutExtension($SourceExe)
    $Desktop = [Environment]::GetFolderPath("Desktop")
    if($TargetFileName -eq '')
    {
        $DestinationPath = "$Desktop\$BaseName.lnk"
    }
    else
    {
        $DestinationPath = "$Desktop\$TargetFileName.lnk"
    }
    $Shortcut = $WshShell.CreateShortcut($DestinationPath)
    $Shortcut.TargetPath = $SourceExe
    $Shortcut.Arguments = $Arguments
    
    if($WindowStyle -is [string]) {
        if( $WindowStyle -like "Normal" ) { $WindowStyle = 1 }
        if( $WindowStyle -like "Maximized" ) { $WindowStyle = 3 }
        if( $WindowStyle -like "Minimized" ) { $WindowStyle = 7 }
    }
 
    if( $WindowStyle -ne 1 -and $WindowStyle -ne 3 -and $WindowStyle -ne 7) { $WindowStyle = 1 }
    $Shortcut.WindowStyle = $WindowStyle

    $Shortcut.Save()
    
    #Allen: 20161114: in Windows 2012, while creating a shortcut, must set the flag to "Run as administrator". Otherwise, will be blocked for execution after invoke
    $bytes = [System.IO.File]::ReadAllBytes($DestinationPath)
    $bytes[0x15] = $bytes[0x15] -bor 0x20 #set byte 21 (0x15) bit 6 (0x20) ON
    [System.IO.File]::WriteAllBytes($DestinationPath, $bytes)
