One of my customers asked for a ‘self service tool’ for their users to remove 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:SOFTWAREMicrosoftSoftgrid4.5ClientApplications)

{

# Get all subkeys from HCKU:

$HKLM = 2147483650

$key = “SOFTWAREMicrosoftSoftgrid4.5ClientApplications”

$reg = [wmiclass]‘\.rootdefault: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

}

$AppName = Get-RegistryValue HKLM:SOFTWAREMicrosoftSoftgrid4.5ClientApplications$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

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.
