# SECTION RETIREE : SUPPRESSION DEFENDER
# ============================================================

# ------------------------------------------------------------
# Cette section a été volontairement retirée.
#
# Raisons :
# - Windows 11 réinstalle souvent Defender automatiquement
# - suppression complète peut casser Windows Update
# - peut provoquer instabilités système
# - certaines versions nécessitent TrustedInstaller
# - Microsoft protège fortement Defender désormais
#
# Alternative recommandée :
#
# Désactivation partielle :
#
# Set-MpPreference -DisableRealtimeMonitoring $true
#
# ou utilisation d'un outil externe :
# - Defender Control
# - O&O ShutUp10++
# - Sophia Script
