Editing shortcut (.lnk) properties with Powershell

Question

I've found a nasty VBS way to do this, but I'm looking for a native PoSh procedure to edit the properties of a .LNK file. The goal is to reach out to remote machines, duplicate an existing shortcut with most of the correct properties, and edit a couple of them.

If it would just be easier to write a new shortcut file, that would work too.

Answer 1

Copy-Item $sourcepath $destination  ## Get the lnk we want to use as a template
$shell = New-Object -COM WScript.Shell
$shortcut = $shell.CreateShortcut($destination)  ## Open the lnk
$shortcut.TargetPath = "C:\path\to\new\exe.exe"  ## Make changes
$shortcut.Description = "Our new link"  ## This is the "Comment" field
$shortcut.Save()  ## Save

Found the VB version of the code here: http://www.tutorialized.com/view/tutorial/Extract-the-target-file-from-a-shortcut-file-.lnk/18349

Answer 2

Below are the functions I use for dealing with .lnk files. They are modified versions of the functions found here as mentioned by @Nathan Hartley. I've improved Get-Shortcut to handle wildcards like * by passing strings to dir to expand them into sets of FileInfo objects.

function Get-Shortcut {
  param(
    $path = $null
  )

  $obj = New-Object -ComObject WScript.Shell

  if ($path -eq $null) {
    $pathUser = [System.Environment]::GetFolderPath('StartMenu')
    $pathCommon = $obj.SpecialFolders.Item('AllUsersStartMenu')
    $path = dir $pathUser, $pathCommon -Filter *.lnk -Recurse 
  }
  if ($path -is [string]) {
    $path = dir $path -Filter *.lnk
  }
  $path | ForEach-Object { 
    if ($_ -is [string]) {
      $_ = dir $_ -Filter *.lnk
    }
    if ($_) {
      $link = $obj.CreateShortcut($_.FullName)

      $info = @{}
      $info.Hotkey = $link.Hotkey
      $info.TargetPath = $link.TargetPath
      $info.LinkPath = $link.FullName
      $info.Arguments = $link.Arguments
      $info.Target = try {Split-Path $info.TargetPath -Leaf } catch { 'n/a'}
      $info.Link = try { Split-Path $info.LinkPath -Leaf } catch { 'n/a'}
      $info.WindowStyle = $link.WindowStyle
      $info.IconLocation = $link.IconLocation

      New-Object PSObject -Property $info
    }
  }
}

function Set-Shortcut {
  param(
  [Parameter(ValueFromPipelineByPropertyName=$true)]
  $LinkPath,
  $Hotkey,
  $IconLocation,
  $Arguments,
  $TargetPath
  )
  begin {
    $shell = New-Object -ComObject WScript.Shell
  }

  process {
    $link = $shell.CreateShortcut($LinkPath)

    $PSCmdlet.MyInvocation.BoundParameters.GetEnumerator() |
      Where-Object { $_.key -ne 'LinkPath' } |
      ForEach-Object { $link.$($_.key) = $_.value }
    $link.Save()
  }
}

Answer 3

I don't think there's a native way.

There is this DOS util: Shortcut.exe.

You still need to copy the util to the remote system, then possibly call it using WMI to make the changes you're looking for.

I'm thinking the easier way will be to overwrite and/or create a new file.

Do you have access to these systems via a remote share?

A short addition to @JasonMArcher's answer..

To see available properties you can just run $shortcut after $shortcut = $shell.CreateShortcut($destination) in a PS. This will print all properties and their current values.
