  Enable this feature to allow suspicious files to be sent to Microsoft for further analysis. This can improve threat detection over time.

• Periodic Scans:
  Even if you rely on real-time protection, schedule regular full system scans to catch any potential threats that might have slipped through.

Overview:
The Windows Firewall acts as a barrier between your PC and potential external threats by monitoring and controlling incoming and outgoing network traffic.

Key Settings and Actions:

• Configure Inbound and Outbound Rules:
  Customize rules to block or allow traffic from specific applications or ports. This is particularly useful if you require additional security for sensitive applications.

• Network Location Awareness:
  Set your network profile appropriately (e.g., Public for coffee shops and Private for home) to ensure the firewall enforces the correct level of security.

Overview:
Regular updates are crucial for protecting your system from known vulnerabilities. Windows Update automatically downloads and installs critical patches and security updates.

Key Settings and Actions:

• Automatic Updates:
  Enable automatic updates to ensure you never miss a critical patch.
