Windows Security Setting

This section walks you through the key steps to disable certain protections in Windows (like real-time virus scanning and the firewall) so that your POS application can install and run smoothly without interference.

Windows Defender

1. Windows Start> Settings> Update & Security

2. Windows Security> Open Windows Security

3. Virus & Threat Protection

4. Manage Setting

5. Turn off all options in the section.

Note: Real-time protection may automatically re-enable after a reboot—this is expected and won’t affect the installation once it’s complete.

Windows Firewall

1. Control Panel> System and Security> Windows Defender Firewall> Turn Windows Defender Firewall on or off

 2. Turn off the Windows Defender Firewall for Private Network
