  $Result = Get-ItemProperty $Path -ErrorAction SilentlyContinue

  if($Result -eq $null) { New-Item $Path }

  Set-ItemProperty $Path -name "AllowCortana" -value 0
}

  $TargetList | % {
    Get-AppxPackage $_ | Remove-AppxPackage

    $DismTarget = GetPackageNameByDispName($_)
　　DISM /Online /Remove-ProvisionedAppxPackage /PackageName:$DismTarget
  }
}

function GetPackageNameByDispName($Disp) {
  if ($DismList.Count -eq 0) {
    DISM "/Online", "/English", "/Get-ProvisionedAppxPackages" | Select-String "PackageName" | % {
      $DismList += $_.ToString().Replace("PackageName : ", "")
    }
  }

  $Result = ""

  $DismList | % {
    if ($_.Contains($Disp)) {
      $Result = $_

      # breakしたらこのループだけじゃなくて全ループ抜けるとかクールでイケてる仕様だな（死ねって意味で）
      # break
    }
  }

  $Result
}

#　終わったら再起動するのよ
KillCortanaService
