Не удается удалить универсальные приложения с помощью PowerShell

пост чистое удаление системных приложений (ошибка обхода 0x80073CFA) содержит этот сценарий PowerShell:

  }

  $ProcessHandle = (Get-Process -id $pid).Handle
  $type = Add-Type $definition -PassThru

function Take-Over($path) {

  $acl.SetAccessRule($rule)
  $key.SetAccessControl($acl)

do {} until (Enable-Privilege SeTakeOwnershipPrivilege)

function Remove-Package($name) {  
  $key = "SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages$name"
  Take-Over $key
  Remove-Item -Path HKLM:"$key\Owners" -Force -Recurse
  & C:\Windows\System32\PkgMgr.exe /up:$name /norestart /quiet
}

#Remove Feedback
$packageBase = "Microsoft-WindowsFeedback"
$packageNames = (dir ("HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages\" + $packageBase + "*")).name

forEach ($package in $packageNames)
{   
    Remove-Package $package.substring($package.indexOf($packageBase))
}

при использовании этого скрипта автор замечает:

вы можете изменить $packageBase на другие имена пакетов.

Я не пробовал этот скрипт себе.
