Hi @KitKat118
Welcome to the HP Support Community.
Thank you for posting your query.
I understand that Windows Defender Firewall is not opening on your HP Pavilion All-in-One 24-r014. Could you please confirm whether you receive any error message and whether the issue started after a recent Windows update or software installation? Also, are you using any third-party antivirus software? Meanwhile I would request you to please follow the steps:
- Opening Windows Firewall: Search for and open Settings, select Privacy & security, click Windows Security, and select Firewall & network protection. You can also search directly for Firewall & network protection.
- Third-Party Antivirus Conflicts: If a third-party antivirus application is installed, Windows Security automatically turns off, which can impact firewall behavior.
- System Policy Restrictions: If the device is managed by an organization or IT department, policy settings can block access to Windows Firewall configurations.
- Restoring Defaults: Within the Firewall settings panel, there is an option to Restore firewalls to default

Take care and have an amazing day!
