Windows 11 implements hardware-enforced stack protection to prevent memory-based attacks. This feature works with compatible CPUs to create a security boundary that malware cannot cross.

2. Improved Malware Protection

Microsoft Defender Antivirus in Windows 11 includes:
- Real-time scanning
- Cloud-delivered protection
- Ransomware detection
- Tamper protection

3. Secured-core PC Requirements

Windows 11 Secured-core PCs combine identity, virtualization, operating system, hardware, and firmware protection:

  • System Guard Secure Launch
  • Firmware protection
  • Dynamic Root of Trust Measurement

Security Updates and Support Timeline

Windows 11 benefits from Microsoft's modern approach to updates:

Feature Windows 10 Windows 11
Security Updates Until October 2025 October 2031
