🎮 Usage

Interactive Mode (Default)

1. Execute the script with administrator privileges
2. Navigate through the interactive menu system:
   • Browse categories to see available optimizations
   • Select specific optimizations or use "Recommended Settings"
   • Preview changes with detailed explanations
   • Apply optimizations with real-time progress tracking
3. Restart when prompted to apply all changes

Silent Mode (Automation)

For automated deployment or enterprise environments:

# Apply recommended settings automatically
iex "& { $(irm 'https://raw.githubusercontent.com/Cykeek/Win10-Network-Tuning/main/NetworkOptimizer.ps1') } -Silent"

Preview Mode (Testing)

See what changes would be made without applying them:

# Show all changes that would be applied
iex "& { $(irm 'https://raw.githubusercontent.com/Cykeek/Win10-Network-Tuning/main/NetworkOptimizer.ps1') } -WhatIf"
