Microsoft 365 Business Basic, Business Standard, and Business Premium now include an extra 50 GB of primary Exchange Online mailbox storage, raising the supported limit from 50 GB to 100 GB. The primary mailbox is the user's active inbox, calendar, and contacts. Microsoft delivers the increase as a licensing change through a new service plan, a named capability inside the product license, rather than as a new mailbox type. The packaging rollout started in June 2026 and continues through September 2026. You should verify the result per user, because not every mailbox in a tenant receives the extra quota at the same time.

Microsoft’s Windows 11 26H1 build 28120.2760 adds automatic PDF and non-HTML download previews to File Explorer, support for in-app purchases in elevated WinUI 3 apps, and a fix for disappearing mouse pointers.

Nvidia’s Agentic Variation Operators (AVO) is a research harness that wraps an AI model with tools, memory, feedback loops, and a supervisory agent. By placing Claude Opus 5 inside this system, Nvidia lifted its score from 30% to 100% on ARC-AGI-3, solving all 183 puzzles across the benchmark’s 25 interactive games. The result suggests that harness design can matter as much as, or more than, changing the underlying model for difficult, long-running agent tasks.

Anthropic is expanding Claude Mythos 5 beyond its limited defender program: Claude Enterprise customers can now use it through Claude Security to scan codebases, identify vulnerabilities, and propose patches. The company is also integrating the model into partner security products and launching a $35 million credit fund for open-source software security, while keeping direct model access restricted.

A Microsoft-signed driver built into Defender can be repurposed to remove antivirus and EDR components before they start, giving attackers with administrator-level privileges a powerful boot-time evasion technique. Check Point Research says the approach works from Windows 7 through Windows 11 25H2, bypasses common driver-blocking controls, and is not currently linked to real-world attacks.

A newly identified malware family called SynkLoader is being delivered through Microsoft Teams phishing messages that impersonate corporate IT staff. Its most deceptive component displays a fake Windows lock screen to capture passwords, while other modules provide persistence, remote control, network tunneling, and reconnaissance that could support ransomware attacks.

Windows 11 build 26340.9233 is rolling out in the Experimental channel with per-app camera, microphone, and location permissions for traditional Win32 software, turning a previously tested 26H2 feature into part of the latest preview release.

Wi-Fi 7’s mandatory WPA3 security is exposing a new compatibility problem: the workaround designed to keep older clients connected requires support that many devices do not have. CableLabs is urging access-point, chipset, and client manufacturers to prioritize WPA3-Personal Compatibility Mode before more home networks encounter devices that suddenly cannot connect.

Anthropic’s new invisible watermarks for Claude-generated text are already being circumvented in multiple ways. Within hours of the announcement, Guillaume Meyer published an open-source remover, while other developers demonstrated rewriting, character substitution, sentence reshuffling, and translation-based techniques that can erase or weaken the machine-readable signal.

AI agents are turning the familiar per-user SaaS model into a budgeting and governance problem for IT teams. Non-human identities may outnumber employees by 25 to 50 times, while the software work they perform generates inference, API, tool-call, and automation costs that seat counts cannot measure.

GitHub Copilot in Slack is now in public preview, letting teams mention `@GitHub` in a channel, thread, or direct message to investigate issues, plan changes, and hand coding tasks to an agent. Copilot works asynchronously in a secure cloud sandbox, then can open a pull request and return a review link to Slack, with Slack Code providing a dedicated workspace for the task.

Microsoft Teams users can now turn a channel, thread, or direct message into a shared GitHub Copilot cloud-agent session. The public preview lets teams steer coding work together, but administrators must enable cloud-agent and sandbox policies, manage separate usage budgets, and consider extra approval requirements for Copilot-created pull requests.
