====== Windows Server Update Services ======
Windows Server Update Services (WSUS) est un service permettant de distribuer les mises à jour pour Windows et d'autres applications Microsoft sur les différents ordinateurs fonctionnant sous Windows au sein d'un parc informatique. WSUS est un rôle pour serveur Windows lui permettant ainsi de devenir un serveur de mises à jour local (ou proxy de mises à jour). Ce serveur télécharge et stocke ponctuellement l'ensemble des mises à jour disponibles auprès des serveurs Windows Update de Microsoft et rend possible le contrôle de la diffusion de celles-ci dans le parc.
===== Outils autour de WSUS =====
Wsus Package Publisher permet de publier vos propres mises à jour sous forme de fichiers MSI, MSP ou EXE. Ainsi, vous pouvez déployer des applications telles qu'Adobe Reader, Java, Flash Player ou Symantec Endpoint Protection. Et les mettre à jour.\\
\\
Vous pourrez importer des mises à jour à partir de catalogues d'éditeur (Adobe, Dell, HP...). Afin de publier des pilotes ou firmware pour votre matériels.\\

==== WSUS Offline ====
WSUS Offline Update est un logiciel de gestion des mises à jour destiné à certaines applications et systèmes d'exploitation de Microsoft. Contrairement au service WSUS de Microsoft, WSUS Offline Update permet d'enregistrer les mises à jour sur un média pour les distribuer vers différents postes d'un parc informatique hors-ligne (offline) au réseau Internet.\\

==== Function Invoke-WsusDeclineAllSuperSeded ====
Celui-ci utilise l'api Web de WSUS pour décliner l'ensemble des updates dites "Superseded", il faudra ensuite lancer un nettoyage dans le serveur.
<sxh powershell>
function Invoke-WsusDeclineAllSuperSeded {
    <#
    .SYNOPSIS
        On Wsus, performs a find all updates with IsSuperseded with value True to Decline this update via web api.
    .EXAMPLE
        PS> Invoke-WsusDeclineAllSuperSeded
    
        Performs a find all updates with IsSuperseded with value True to Decline this update via local web api. 
    .EXAMPLE
        PS> Invoke-WsusDeclineAllSuperSeded -FQDN wsus.example.org -portNumber 8531 -useSecureConnection $true      
    
        Performs a find all updates with IsSuperseded with value True to Decline this update via remove web api, use the port number 8531 and use secure connection.
    .PARAMETER FQDN
        Set the fully qualified domain name like this : myhost.example.com. The FQDN uniquely distinguishes the device from any other hosts called myhost in other domains.
    .PARAMETER portNumber
        Set the communication port, by default this parameter is set on 8530.
    .PARAMETER useSecureConnection
        If your Wsus use a SSL certificate, please set this parameter to $true, by default this parameter is set on $false.

==== Invoke-DeclineUpdates ====
Une version alternative que j'ai trouvé [[https://gallery.technet.microsoft.com/scriptcenter/Decline-superseded-and-922d6d82|ici]], il y a de bonne idée mais, j'ai préféré ne pas mettre en place, car il utilise les rsat de WSUS.

.Synopsis 
   Sample script to decline superseded updates from WSUS, and run WSUS cleanup if any changes are made  

.DESCRIPTION 
   Declines updates from WSUS if update meets any of the following:
        - is superseded
        - is expired (as defined by Microsoft)
        - is for x86 or itanium operating systems
        - is for Windows XP
        - is a language pack
        - is for old versions of Internet Explorer (versions 7,8,9)
        - contains some country names for country specific updates not filtered by WSUS language filters.
        - is a beta update
        - is for an embedded operating system

    If an update is released for multiple operating systems, and one or more of the above criteria are met, the versions of the update that do not meet the above will not be declined by this script
