# WINDOWS 11 PERFORMANCE OPTIMIZATION FOR REMOTE STREAMING
# MODE: MAXIMUM PERFORMANCE (Defender enabled)
# ------------------------------------------------------------

# Windows Defender remains active to ensure system protection.
#
# How to Run:
# 1. Save this script as "Optimize-Windows11.ps1".
# 2. Open PowerShell as Administrator and run: Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
# 3. Right-click the file and select "Run with PowerShell".
#    (Alternatively, open PowerShell as Administrator and run it manually.)
