One of my customers asked for a ‘self service tool’ for their users to remove Microsoft APP-V pkg files from their profiles. Because there’s no direct relation between the registry values and the location of the pkg files I had to be creative with a search within this script:

#=================================================================
# AUTHOR: Kees Baggerman

# COMPANY: Inter Access B.v.

# DATE: 21-02-2010

# Version: 0.2

# Puts all the app-v applications in an drop down menu

# and removes the PKG files from the selected application.

#=================================================================

if (Test-Path HKLM:\SOFTWARE\Microsoft\Softgrid\4.5\Client\Applications)

{

# Get all subkeys from HCKU:\

$HKLM = 2147483650

$key = "SOFTWARE\Microsoft\Softgrid\4.5\Client\Applications"

$reg = [wmiclass]‘\\.\root\default:StdRegprov’

$subkeys = $reg.EnumKey($HKLM, $key)

$subkeys.snames

# Put all of the registry keys in an array and put that in a dropdown menu.

[array]$DropDownArray = $subkeys.snames

# This Function Returns the Selected Value and Closes the Form

function Return-DropDown {

$Choice = $DropDown.SelectedItem.ToString()

$Form.Close()

function Get-RegistryValue($key, $value) {

(Get-ItemProperty $key $value).$value

}

$AppName = Get-RegistryValue HKLM:\SOFTWARE\Microsoft\Softgrid\4.5\Client\Applications\$Choice `

AppPath

$AppName = $AppName.Substring(1,8)

Function FindFolder

{

$input | Where-Object {$_.Name -match $AppName}

}

$AppLoc = Get-ChildItem -Path $Env:AppData | FindFolder

Remove-Item $Env:AppData\$AppLoc -recurse

}

[System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")

[System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")

$Form = New-Object System.Windows.Forms.Form

$Form.StartPosition = "CenterScreen"

$Form.width = 300

$Form.height = 150

$Form.Text = ”AppVPKGRemover”

$DropDown = new-object System.Windows.Forms.ComboBox

$DropDown.Location = new-object System.Drawing.Size(100,10)

$DropDown.Size = new-object System.Drawing.Size(130,30)

ForEach ($Item in $DropDownArray) {

$DropDown.Items.Add($Item)

}

$Form.Controls.Add($DropDown)

$DropDownLabel = new-object System.Windows.Forms.Label

$DropDownLabel.Location = new-object System.Drawing.Size(10,10)

$DropDownLabel.size = new-object System.Drawing.Size(100,20)

$DropDownLabel.Text = "Applications"

$Form.Controls.Add($DropDownLabel)

$Button = new-object System.Windows.Forms.Button

$Button.Location = new-object System.Drawing.Size(100,50)

$Button.Size = new-object System.Drawing.Size(100,20)

$Button.Text = "Remove files"

$Button.Add_Click({Return-DropDown})

$form.Controls.Add($Button)

$Button1 = new-object System.Windows.Forms.Button

$Button1.Location = new-object System.Drawing.Size(100,75)

$Button1.Size = new-object System.Drawing.Size(100,20)

$Button1.Text = "Quit"

$Button1.Add_click({ $form.close() })

$form.Controls.Add($Button1)

$Form.Add_Shown({$Form.Activate()})

$Form.ShowDialog()

}

else

{

[System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")

[System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")

$Form = New-Object System.Windows.Forms.Form

$Form.StartPosition = "CenterScreen"

$Form.width = 300

$Form.height = 150

$Form.Text = ”AppVPKGRemover”

# Create the label control and set text, size and location

$label = New-Object Windows.Forms.Label

$label.Location = New-Object Drawing.Point 100,50

$label.Size = New-Object System.Drawing.Size(125,20)

$label.text = "App-V is not installed!"

$form.controls.add($label)

$Button1 = new-object System.Windows.Forms.Button

$Button1.Location = new-object System.Drawing.Size(100,75)

$Button1.Size = new-object System.Drawing.Size(100,20)

$Button1.Text = "Quit"

$Button1.Add_click({ $form.close() })

$form.Controls.Add($Button1)

$Form.Add_Shown({$Form.Activate()})

$Form.ShowDialog()

}

A small disclaimer: Powershell and scripting is not my day to day work so it’s possible that this script has a couple of flaws. I did a lot of copy/pasting from a couple of blogs and MS posts but feel free to use this script. It’s a draft version thus I can’t guarantee that this will work but in my test environment it does. If you have additional comments just drop a comment so I can optimize this script.
