Hi @Thundra,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If your Windows Security system is not turning on and you’ve tried various troubleshooting methods without success, here’s a step-by-step guide to address the issue. These steps cover a range of solutions, from simple checks to more advanced troubleshooting methods:

1. Check for Conflicting Antivirus Software

1. Third-Party Antivirus:
   • Ensure that no third-party antivirus software is installed or interfering. Sometimes, third-party antivirus programs disable Windows Security.
   • If a third-party antivirus is installed, temporarily disable or uninstall it to see if Windows Security turns on.

2. Restart Windows Security Services

1. Restart Services:
   • Press Windows Key + R, type services.msc, and press Enter.
   • In the Services window, find Windows Defender Antivirus Service and Windows Defender Firewall.
   • Right-click each service and select Restart. If the service is not running, right-click and choose Start.

3. Check for Windows Updates

1. Update Windows:
   • Go to Settings > Update & Security > Windows Update.
   • Check for updates and install any available updates. Sometimes, security updates can fix issues with Windows Security.

4. Run the Windows Security Troubleshooter

1. Troubleshooter:
   • Go to Settings > Update & Security > Troubleshoot.
   • Click on Additional troubleshooters and select Windows Store Apps or Windows Security if available.
   • Follow the prompts to run the troubleshooter and apply any fixes.

5. Check Group Policy Settings

Group Policy Editor:

• Press Windows Key + R, type gpedit.msc, and press Enter.
• Navigate to Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Antivirus.
• Ensure that Turn off Microsoft Defender Antivirus is set to Not Configured or Disabled.

Check for Other Policies:

• Also, check under Computer Configuration > Administrative Templates > Network > Network Connections > Windows Defender Firewall for any settings that might disable it.

I hope this helps.

Take care and have a good day.
