Microsoft is enhancing the security framework of Windows through the Secure Future Initiative, focusing on trust, privacy, and enterprise controls. Key features include the introduction of Post-Quantum Cryptography (PQC) APIs for quantum-safe encryption, and an upgrade to BitLocker with hardware-accelerated support for improved disk encryption, set to roll out on new Windows 11 devices in Spring 2026. Microsoft is also integrating passkey manager support with Windows Hello, allowing users to choose from various passkey managers. Windows 11 employs App Control for Business to ensure only trusted applications run, while Microsoft Intune’s Managed Installer helps IT teams manage business applications. Additionally, Sysmon functionality will be integrated into Windows 11 and Windows Server 2025 for better threat detection. Microsoft is implementing Zero Trust DNS for encrypted name resolution and supporting Wi-Fi 7 for Enterprise with WPA3-Enterprise authentication. The Windows Resiliency Initiative (WRI) includes stricter driver standards, a shift in antivirus enforcement from kernel to user mode, and new safeguards like driver isolation and DMA remapping to enhance system stability.
