Propósito:
En ocasiones o los PC tardan en entrar en el Wsus o el Wsus en ver los PCs, con lo que he crea un script, para ejecutar en los PCs, para refrescar esta conexión e intentar que se vean sin problemas.
Crea un log en C:\Windows\Temp\wsus_task.
Es una herramienta en la que estoy muy contento, pero cuando le pasa algo no es fácil saber que le esta pasando.
Pasos:
El Script:

# WSUS FULL RESET - ENTERPRISE PRO

Add-Content -Path $log -Value "$timestamp [$level] - $msg"
}
# --- EJECUCIÓN COMANDOS (CLAVE) ---
function Run-Command {
param(
[string]$name,
[scriptblock]$command

Write-Log "$name - START"
