# Windows-WSUS-PSWindowsUpdate

Ce module sert à rechercher, installer et désinstaller les mises à jour, mais également à afficher la configuration de Windows Update, à afficher l’historique des mises à jour et à réinitialiser le composant Windows Update. Voilà pour ses fonctionnalités principales, car, comme vous le verrez ci-dessous, il intègre un grand nombre de commandes.

Il est disponible sur le site PowerShell Gallery et il s’installe avec la commande suivante :
```powershell
Install-Module -Name PSWindowsUpdate -Force
```
Remarque : Si vous rencontrez une erreur, il est possible que vous devez utiliser le protocole TLS 1.2 

Le référentiel Microsoft nécessite TLS 1.2 ou TLS 1.3 à partir des machines clientes Windows 10/11. Voici la commande pour utiliser TLS1.2
```powershell
[Net.ServicePointManager]::SecurityProtocol=[Net.SecurityProtocolType]::Tls12
```
Pour lister mises à jour disponibles :
