Microsoft Brings Post-Quantum Security To Windows 11 And Linux

Microsoft is incorporating post-quantum cryptography (PQC) into Windows 11 and Linux platforms to enhance its security framework against potential threats from quantum computing. PQC functionalities are now available to Windows Insiders via the Canary Channel Build 27852 and on Linux through SymCrypt-OpenSSL version 1.9.0, allowing customers to test quantum-resistant encryption. Microsoft is enhancing its core cryptographic library, SymCrypt, with new PQC algorithms designed to withstand future quantum decryption capabilities. The company emphasizes the importance of "crypto agility," enabling systems to adapt to new algorithms as they develop. This initiative is part of Microsoft's ongoing commitment to global quantum-safe initiatives and aims to foster innovation and preparedness within the cybersecurity community.

Announcing Windows 11 Insider Preview Build 27868 (Canary Channel)

Windows 11 Insider Preview Build 27868 has been released to the Canary Channel. There are no plans to release SDKs for the 27xxx series builds. The voice access feature has been enhanced with a new in-product experience to highlight new features. A fix has been implemented for pen input issues on certain PCs, and problems with launching applications like Spotify from the Microsoft Store have been addressed. A rendering issue in the Group Policy Editor for some display languages has been corrected, and a SYSTEMTHREADEXCEPTIONNOTHANDLED bugcheck issue has been fixed. Known issues include potential loss of Windows Hello PIN and biometrics for Copilot+ PCs transitioning to the Canary Channel, an Administrative Templates error in the Group Policy Editor, taskbar display issues after upgrading, and audio problems with high sampling rate devices. Applications reliant on virtualization will require the "Windows Hypervisor Platform" component when Virtualization Based Security is enabled. Search and filtering options in Task Manager are currently non-operational. Insiders in the Canary Channel should note that builds reflect early development changes and may not align with any specific Windows release. Features may not reach the general public, and a clean installation is required to exit the Canary Channel. The desktop watermark is standard for pre-release builds.

Windows 11 is getting top-level protection against the next generation of quantum cyberattacks

Microsoft has announced new protective measures against potential quantum-powered cyber threats by rolling out post-quantum cryptography (PQC) capabilities for Windows Insiders using Canary Channel Build 27852 and higher, and for Linux users through SymCrypt-OpenSSL version 1.9.0. The newly introduced PQC algorithms, standardized by NIST, will evolve in response to emerging threats, emphasizing the need for "Crypto Agility." The updates enhance OpenSSL’s API surface for Linux developers, allowing experimentation with TLS hybrid key exchange. Experts warn that quantum computing could breach even the most robust encryption systems, highlighting the urgency for software companies to adapt their security measures.

Windows 11 Introduces Enhanced Administrator Protection to Strengthen Security Against Elevated Privilege Attacks

Microsoft has launched Administrator Protection for Windows 11, a feature designed to enhance cybersecurity by preventing privilege escalation attacks. This feature creates a security boundary around administrative operations, reducing the attack surface for cybercriminals. It introduces a hidden, system-managed local user account that generates isolated admin tokens, preventing user-level malware from compromising elevated processes. Administrator Protection eliminates auto-elevation functionality, requiring users to explicitly authorize administrative actions. It utilizes a System Managed Administrator Account (SMAA) that generates non-persistent admin tokens for specific tasks, which are discarded after use. The feature is currently available to Windows Insiders in the Canary channel and will expand to the Dev channel, with broader deployment expected in the 24H2 release. Compatibility challenges may arise in complex development environments, such as with Visual Studio.

Announcing Windows 11 Insider Preview Build 27858 (Canary Channel)

Windows 11 Insider Preview Build 27858 has been released to the Canary Channel. A new system tray icon for the emoji and more panel has been introduced, allowing users to access emojis, GIFs, and Kaomojis, with customization options available. Several fixes have been implemented, including resolving black screen issues during upgrades, enhancing accessibility in File Explorer, updating desktop icon logic, fixing voice typing initiation issues, resolving explorer.exe crashes related to snap layouts, addressing taskbar icon resizing problems in tablet mode, fixing night light functionality, and resolving MIDI device recognition issues. Known issues include potential problems with Windows Hello PIN and biometrics on new Copilot+ PCs and unresponsive pen input on certain devices. Insiders are reminded that builds in the Canary Channel are early development versions and may change. A clean installation is required to exit the Canary Channel, and a desktop watermark will be present in pre-release builds.

Windows Insider release blocked by OS-busting bug

The Windows team at Microsoft has discovered a significant bug affecting the Canary build, which has led to the delay of several Insider builds. This bug impacts essential functionalities such as Bluetooth and Wi-Fi connectivity, USB accessory connections, and the onboard camera for Windows Hello. Brandon LeBlanc from the Windows Insider program described the bug as "really bad" and noted that it arose from a specific code change in newer builds not yet released to Insiders. Microsoft is currently working on a fix and hopes to deliver a new build to the Canary channel by the end of the week. The situation emphasizes the company's focus on quality control to prevent flawed releases from reaching users.

Windows Insider Program: What is it and why you should consider joining it (and few reasons you shouldn’t)

The Windows Insider Program allows users to explore unreleased features of Microsoft's Windows operating system by enrolling in various channels. To join, Windows 11 users can go to Settings >> Windows Update and select Windows Insider Program, enabling optional diagnostic data sharing with Microsoft. There are four channels to choose from: 1. Canary Channel: For technical users wanting to preview early-stage features, often unstable. 2. Dev Channel: More stable than Canary, includes features under consideration for future releases. 3. Beta Channel: Recommended for most users, offers a balance of stability and innovation with features likely to be rolled out to all users. 4. Release Preview Channel: The most stable option, providing a preview of the next major release with tested functionalities. Reasons to join include early access to new features, the ability to provide feedback to Microsoft, professional advantages for IT administrators, community engagement, and skill improvement. However, drawbacks include potential system instability and bugs, as well as privacy concerns related to sharing diagnostic data.

Windows 11 25H2 shows signs of life: what can we expect?

The upcoming Windows 11 25H2 update is expected to be a modest enhancement rather than a major overhaul, continuing to use the Germanium codebase established with 24H2. A preview build, specifically build 27842 from the Canary Channel, has been identified, and references to GE25H2 were found in the AppraiserRes.dll file, which assesses PC compatibility for the new version. The update is anticipated to arrive in the latter half of the year, similar to previous incremental updates. Concerns exist regarding the stability of 25H2 compared to 24H2, which faced installation issues and compatibility problems. Windows 10 will reach the end of regular support on October 14, 2025, prompting users to transition to Windows 11. Smaller updates like enablement packages tend to present fewer stability risks, and Microsoft has not officially confirmed any details about 25H2 or its update process for versions 23H2 and 24H2. Speculation about Windows 12 continues, but its timeline remains uncertain.

Microsoft set to make huge Windows change — and it’s hoping you won’t notice

The Windows 11 Insider Preview Build (27842) will replace the Blue Screen of Death (BSoD) with a new error screen featuring a Medium Forest Green backdrop. This change is part of an effort to create a more streamlined user interface for unexpected restarts, although it may provide less context for troubleshooting. The new design is currently being tested in Microsoft's Canary Channel and is expected to become standard with the Windows 11 25H2 update later this year.
