##Overview The dism module enables and disables Windows Features using the DISM utility provided by Microsoft

##Module Description

This module provides a dism puppet resource type on Windows. Windows Deployment Image Servicing and Management (DISM.exe) is used to enable or disable Windows features on Windows 7 SP1, Windows 8, Windows Server 2008 R2, Windows Server 2012, Windows 2012 R2

Enable or Disable Windows Features What is DISM?

##Setup

###What dism affects dism will modify the existing features on the system, whether enabling or disabling. In some instances the server will be restarted unless explicity setting the parameter norestart to true

###Setup Requirements The module requires that dism be installed on your system, in most cases this will be there by default. In some cases, such as Windows 7 it requires SP1 or to be manually installed.

##Usage ###To enable DotNet3 and all child settings

dism { 'NetFx3':
  ensure => present,
  all    => true,
  source => 'Z:\2012r2\sxs'
}

###To install IIS and provide an answer file for all setup steps

dism { 'IIS-WebServer':
  ensure => present,
  answer => 'C:\answer\iis.xml',
}

###To disable Internet Explorer and prevent restart

dism { 'Internet-Explorer-Optional-amd64':
  ensure    => absent,
  norestart => true,
}

##Reference ###Deployment on Azure Windows Server 2012 R2 Datacentre (Image from Azure Store) ####Windows Server 2012 R2 Datacentre does not have dism installed under c:\windows\sysnative ####it is under c:\windows\system32 ####to use it with no error, add the following file resource into your base code (before instantiating dism)

  file { 'C:/Windows/sysnative' :
    ensure  => directory,
  } ->
  file { 'C:/Windows/sysnative/dism.exe' :
    ensure             => present,
    source             => 'c:/windows/system32/dism.exe',
    source_permissions => ignore,
  }
