GitHub Copilot CLI—GitHub's AI assistant for the terminal—introduced an experimental feature called Rubber Duck that pairs your primary AI model with an independent reviewer from a completely different AI vendor. The goal is to catch early planning mistakes before they compound into harder-to-fix downstream errors, a known weakness of single-model AI agents. In performance testing on real-world coding problems, combining Claude Sonnet with Rubber Duck closed 74.7% of the performance gap between Sonnet and the more capable Opus tier.

Microsoft announced a breaking change to the Microsoft Graph API affecting Exchange Online: from December 31, 2026, applications that modify sensitive email properties -- such as the subject, body, or recipients -- on delivered messages must hold elevated Mail-Advanced.ReadWrite permissions. Until now, the standard Mail.ReadWrite permission was sufficient for these operations. The new permissions require explicit approval from the tenant administrator ("admin consent"). If you operate Microsoft 365 and have custom applications or third-party tools that interact with email via the Graph API, you need to audit and potentially update these apps before the enforcement date.

Microsoft's original Secure Boot certificates from 2011 begin expiring in June 2026. Windows devices that still rely on these certificates will no longer receive security updates for boot components, leaving them out of compliance. To address this, Microsoft is rolling out new 2023 certificates for the UEFI Secure Boot Signature Database (DB). Administrators can deploy these certificates to domain-joined machines using Group Policy, PowerShell, or the Windows Configuration System (WinCS). This article covers the technical background, the registry-based deployment mechanism, and Microsoft's sample automation framework for enterprise rollouts.

Windows 11 Insider Preview builds introduce a new secure processing mode for batch files and CMD scripts. IT administrators can enable it via a registry value named LockBatchFilesWhenInUse, which prevents batch files from being altered while they execute. The feature also improves performance when Windows Defender Application Control (WDAC) code integrity policies are active. It is currently available in the Dev Channel build 26300.7939, and the Beta Channel build 26220.7934.

Microsoft Secure Boot certificates issued by the 2011 Certificate Authorities (CAs) are expiring starting June 2026. Every Windows device with Secure Boot enabled must be updated to trust the 2023 certificates before expiration to retain security update support. Microsoft provides a monitoring-only approach using Intune Remediations that runs a PowerShell detection script on enrolled devices and reports Secure Boot and certificate status back to the Intune admin center — without making any changes to devices. This article explains the prerequisites, deployment steps, data collected, and how to read the results.

Library management is a new feature in Microsoft Defender for Endpoint that provides security operations teams with a centralized interface for uploading, organizing, and reviewing scripts and files before a live response session begins. Previously, analysts had to upload tools during an active investigation, which delayed response times. The feature is now generally available for enterprise customers and integrates with Microsoft Security Copilot for automated script analysis.

Microsoft has published its planned team investments for PowerShell 7.7, Windows OpenSSH, and Desired State Configuration (DSC) v3.2. The roadmap for PowerShell 7.7 includes relocating PSUserContentPath, non-profile-based module loading, Bash-style aliases, and a Model Context Protocol (MCP) server. For Windows OpenSSH, the primary addition under evaluation is support for Entra ID authentication. Desired State Configuration (DSC) v3.2 will include a new Python adapter to enable the creation of DSC resources on Linux.
