Microsoft’s week is defined by security, a push toward AI that runs on the device, and a simpler Copilot. October’s Patch Tuesday fixed a record 1,411 flaws, including one actively exploited zero-day and two publicly disclosed ones. That same release ended updates for Windows 11 24H2 Home and Pro. At its Oct. 7 event, Microsoft described Windows as a “hybrid intelligence” system that mixes cloud AI with AI running locally. The Surface Laptop Ultra ships tomorrow. Copilot is being consolidated across Microsoft 365, Teams, SharePoint and Copilot Studio. The twice-yearly Dynamics 365 and Power Platform release waves have also been replaced by a continuous roadmap. In the wider AI world, safety, security and cost pressure dominate the headlines. Admins should prioritize patching, review Copilot data-oversharing risks, and adjust their planning habits to a roadmap that now changes continuously.
Windows, Surface and Security
- Windows: Patch Tuesday addressed 70 critical vulnerabilities, and Windows 11 24H2 Home and Pro reached end of updates on October 13.
- Windows: Microsoft says it is working to make Windows the most secure platform for AI agents, and Copilot can act on local files with permission.
- Surface: The Surface Laptop Ultra, powered by Nvidia’s RTX Spark Arm-based chip, starts at $2,599 and releases October 16.
Microsoft 365, Office 365, Copilot Chat, Teams and SharePoint Online
- Microsoft 365 and Copilot: A Copilot app overhaul brings chat and Cowork onto one screen, and Copilot in SharePoint and OneDrive reaches general availability. A spending policy is required for every usage-based capability.
- Teams: A simplified, chat-centered Copilot experience in Teams, with a new Tasks view, became generally available in September. Copilot Chat for chats, channels, calls and meetings reaches GCC, GCC High and DoD in October.
- SharePoint Online: Copilot in SharePoint will build workflows from a plain-language description, targeted for December.
- Office 365 licensing: Business Standard and Premium with Copilot launched in July at $23.50 and $32 per user per month, with promotional pricing through December 2026.
Power Platform, Copilot Studio and Dynamics 365 (CRM and ERP)
- Power Platform (Power Apps, Power Automate, Power Pages): Wave 1 2026 was the final wave. Updates now arrive continuously, and organizations must monitor changes rather than plan around two semiannual releases.
- Dynamics 365: There will be no September 2026 Release Wave 2 announcement, and Release Planner retires November 15. Finance and Operations teams now track both the roadmap and the regular quality-update schedule.
- Copilot Studio: An app- and intent-first agent creation experience is due for general availability in October. Real-time voice agents are generally available, starting in Dynamics 365 Contact Center in North America.
- Power BI: Starting in October, Power BI Desktop versions from March 2026 or earlier can no longer save and share files to OneDrive and SharePoint, so update Desktop.
Developer, Cloud and Data
- GitHub Copilot: GitHub deprecated Gemini 3.5 Flash, Gemini 3.6 Flash, Kimi K2.7 Code and Claude Opus 4.7 on October 2, suggesting newer replacements. GitHub Universe is October 28-29.
- Azure: A report says the Azure president asked leaders to find cost cuts of at least 20%. Microsoft called it “inaccurate and careless.”
- SQL Server: I found no new announcement today. September’s Patch Tuesday included 62 SQL Server fixes.
- Visual Studio: I found no major new announcement today.
Gaming and Xbox
- Game Pass: Chained Beasts and Bluey’s Happy Snaps arrive October 15. A Plague Tale: Requiem and Clair Obscur: Expedition 33 leave the same day.
- Xbox: Microsoft has formed Xbox Labs to research AI-assisted decompilation, recompilation and modding. Xbox denied landing an exclusive streaming deal for GTA 6 at launch.
Artificial Intelligence
- Anthropic warned that small AI models could soon copy themselves across internet-connected devices. The same digest says Anthropic reported $16.8B in quarterly revenue.
- The FBI arrested an OpenAI engineer over a recording device hidden in an executive conference room.
- OpenAI and Anthropic backed binding AI safety rules at a UK parliamentary hearing, while Meta and Google DeepMind resisted.
