Here’s a summary and analysis of Microsoft’s advances against quantum cyberattacks, especially the move to post-quantum cryptography (PQC), as described in your TechRadar article and the latest information from internal sources:
In conclusion:
Microsoft is leading on the practical adoption of post-quantum cryptography, with Windows 11 (and Linux via SymCrypt) now offering experimental but production-intended support for the first set of NIST standardized PQC algorithms (ML-KEM and ML-DSA). These changes will help developers and enterprises prepare for the era when quantum computers can break legacy encryption—fulfilling the goal of “crypto agility” and pro-actively securing Windows as the first-mover among mass-market operating systems.

What’s New in Windows 11’s Quantum-Resistant Security?
1. Quantum Computing as a Cybersecurity Threat
Quantum computers could soon break encryption methods like RSA and ECC, making traditional data security obsolete. The "harvest now, decrypt later" threat means adversaries might collect encrypted info today to decrypt it in the future with quantum tech.2. Microsoft’s New Protections
- PQC Capabilities: Windows 11 is getting post-quantum cryptography support, starting for Windows Insiders (Canary Channel Build 27852+) and on Linux with SymCrypt-OpenSSL 1.9.0.
- Supported Algorithms:
- ML-KEM: (Module Lattice-Based Key Encapsulation Mechanism, formerly CRYSTALS-Kyber) for secure key exchange.
- ML-DSA: (Module Lattice-Based Digital Signature Algorithm, formerly CRYSTALS-Dilithium) for quantum-resistant digital signatures.
- Crypto API Updates: The Cryptography API: Next Generation (CNG) libraries and certificate/messaging functions will be upgraded, allowing developers and companies to start testing and integrating PQC within operational environments.
3. Why This Matters
These are some of the first implementations of NIST-standardized PQC in a mainstream OS. As industry and government adopt quantum-safe algorithms:- Software and SaaS providers can begin to “future proof” systems.
- The changes lay groundwork for secure communications, confidential data-sharing, and digital signatures—now built to withstand quantum attacks.
4. Crypto Agility
Microsoft stresses the importance of “crypto agility,” which is the ability for systems to upgrade or swap cryptographic algorithms as standards evolve (since PQC is still a new and evolving space). Windows 11 is architected to support this agility.5. Not Just for Windows
The same cryptographic primitives are being made available on Linux systems, thanks to SymCrypt-OpenSSL integration, so enterprise systems can stay “quantum safe” across platforms.What’s in Windows 11 Right Now? Internal Insights
- TPM 2.0 Requirement: Windows 11 already raised the security bar with hardware-based protections (like BitLocker encryption, Secure Boot, virtualization-based security). Part of TPM 2.0’s purpose: it supports modern crypto algorithms, and is a building block for future PQC adoption.
- Default Encryption: Upcoming Windows 11 (24H2) will enable BitLocker by default, further ensuring physical device security—though this isn’t directly quantum, it signals Microsoft’s steady tightening of the security baseline.
- Kerberos and AES: Recent changes require advanced encryption (AES, not DES) for network authentication, and prepare the ecosystem for more future-proof security changes.
Big Picture: Quantum-Ready Windows
- Quantum-resistant encryption is no longer theoretical: It’s being rolled out for early/insider builds on major operating systems.
- Next-gen threats anticipate quantum computers at scale: Microsoft, in lockstep with NIST and international security recommendations, is moving toward encryption that can stand up to quantum attacks—the “biggest security threat of all time.”
- Developers and companies: Should begin experimenting and building support for PQC, and prioritize crypto agility in their software roadmaps.
In conclusion:
Microsoft is leading on the practical adoption of post-quantum cryptography, with Windows 11 (and Linux via SymCrypt) now offering experimental but production-intended support for the first set of NIST standardized PQC algorithms (ML-KEM and ML-DSA).
