Microsoft has quietly made a strategic pivot in how Copilot delivers AI: Anthropic’s Claude models — Claude Sonnet 4 and Claude Opus 4.1 — are now selectable backends inside Microsoft Copilot Studio and the Researcher agent in Microsoft 365 Copilot, giving enterprises explicit model choice and turning Copilot from a single‑backend assistant into a multi‑model orchestration platform. This change is additive — OpenAI models remain available — but it materially shifts how organizations must...

Microsoft has quietly but decisively turned Microsoft 365 Copilot into a multi‑model orchestration platform by adding Anthropic’s Claude Sonnet 4 and Claude Opus 4.1 as selectable backends in two visible places: the Researcher agent and Copilot Studio, a move that formalizes vendor diversification and introduces new operational tradeoffs for enterprise IT teams. Background / Overview Microsoft 365 Copilot launched as an integrated productivity assistant across Word, Excel, PowerPoint...

Microsoft has quietly added a limited lifeline for Windows 10 users: a one‑year window of Extended Security Updates (ESU) after the platform’s hard end‑of‑support date, with a free enrollment path for many consumers — but the fix comes with strings attached that raise privacy, usability, and e‑waste concerns. Background Microsoft set a firm end‑of‑support date for Windows 10: October 14, 2025. After that date, standard security updates, feature updates, and general technical support for...

Rufus 4.10 lands with a built-in dark theme, support for Microsoft’s new Windows UEFI CA 2023 signing model, the ability to save a USB stick back to ISO (UDF only), improved VHD/VHDX error reporting, and a handful of reliability fixes that matter to technicians, imaging engineers, and power users alike. The update tightens Rufus’s handling of the evolving Windows 11 installation landscape—most notably by making it straightforward to produce media that is compatible with Microsoft’s renewed...

Microsoft has quietly opened a limited lifeline for millions of Windows 10 users: a one‑year extension of critical security updates at no additional charge — but only if users enroll through a Microsoft account and accept strings attached that have consumer advocates warning of hidden costs, privacy trade‑offs, and a forced migration to newer hardware. Background Windows 10’s official end of support is scheduled for October 14, 2025, after which Microsoft will stop providing routine feature...

Microsoft acknowledged that an August preview update and subsequent September rollups for Windows 11 introduced a regression that can prevent legally purchased Blu‑ray, DVD and some digital‑TV applications from playing DRM‑protected content, producing copyright errors, black screens, freezes or repeated interruptions for affected users. Background Microsoft shipped an optional, non‑security preview update on August 29, 2025—delivered as KB5064081—and those changes were folded into the...

Microsoft’s pitch is simple and seductive: don’t learn a new browser, let the browser learn you. In a string of recent interviews and product updates, Microsoft executives have framed the refreshed Edge — now running a new “Copilot Mode” — as an agentic browser that can take over tedious multi-step tasks, read and compare content across tabs, click buttons, and even (with user approval) complete purchases or reservations on your behalf. The company’s public posture is equal parts ambition...

Microsoft’s Copilot has taken a decisive step away from single‑vendor reliance by adding Anthropic’s Claude family as selectable backends inside Microsoft 365 Copilot, a change that introduces model choice, cross‑cloud execution implications, and fresh governance responsibilities for enterprise IT teams. Background Microsoft 365 Copilot launched as a tightly integrated productivity assistant across Word, Excel, PowerPoint, Outlook and Teams, and for much of its public life it leaned heavily...

The relationship between Microsoft and OpenAI has shifted from near-monogamy to a pragmatic, negotiated partnership — Microsoft is no longer OpenAI’s exclusive cloud provider, but it remains deeply tied to OpenAI through long-term commercial terms and preferred access arrangements. This isn’t a dramatic corporate divorce so much as a strategic rebalancing: OpenAI has gained the right to add other cloud suppliers for raw compute capacity, while Microsoft retains important commercial...

Microsoft's lab demonstration that etches hair‑thin channels into silicon and pumps coolant straight to processor hot‑spots marks one of the most consequential infrastructure experiments in the cloud era — a deliberately engineered attempt to remove the thermal ceiling that is starting to throttle AI compute, reduce the energy wasted on chillers, and open the door to denser, faster server architectures. Background The hyperscale race to power ever‑larger AI models has created an acute...

Microsoft has quietly but decisively turned Microsoft 365 Copilot from a single-vendor experience into a multi-model orchestration platform, adding Anthropic’s Claude Sonnet 4 and Claude Opus 4.1 as selectable backends for key Copilot surfaces while reaffirming that OpenAI will continue to power Copilot’s frontier scenarios. Background Microsoft 365 Copilot launched as a tightly integrated productivity assistant built on large language models (LLMs) and has historically leaned heavily on...

OpenAI and SAP have announced a high‑profile collaboration to deliver a sovereign AI service targeted at Germany’s public sector, pairing OpenAI’s models with SAP’s Delos Cloud and Microsoft Azure infrastructure in an effort to meet strict German data‑sovereignty, security, and compliance requirements. The initiative — marketed as OpenAI for Germany — promises to run model inference and related workloads inside Germany, with SAP planning a substantial GPU capacity expansion and Microsoft...

OpenAI and SAP have announced a high-profile partnership — branded "OpenAI for Germany" — to deliver a sovereign AI service for Germany’s public sector by combining OpenAI’s models with SAP’s Delos Cloud and Microsoft Azure infrastructure, with a planned rollout in 2026 and an initial infrastructure buildout of 4,000 GPUs in Germany. Background Germany has pushed digital sovereignty to the front of its public-policy agenda for several years, driving investment in national and regional...

Microsoft has warned enterprise IT teams that the root Secure Boot certificates baked into most Windows devices since 2012 will begin expiring in 2026, and it is rolling out a new 2023 certificate chain to prevent boot‑time security updates from failing — a change that requires coordinated action by device owners, OEMs, and firmware vendors to avoid losing the ability to patch boot components or to inadvertently block newly signed boot loaders and option ROMs. Background Secure Boot is a...

Microsoft’s push to make Edge an “AI browser” took a decisive step this year with an update that gives Copilot the ability to act on users’ behalf inside the browser — opening and navigating tabs, running searches, and executing multi-step tasks like bookings and form-filling when explicitly authorized. This shift from passive assistance to agentic AI in the browser promises big productivity gains but also widens the attack surface for privacy and security risks — a trade-off Microsoft and...

Microsoft has quietly but decisively reconfigured the architecture of Microsoft 365 Copilot by adding Anthropic’s Claude family — notably Claude Sonnet 4 and Claude Opus 4.1 — as selectable model backends within key Copilot surfaces, marking a shift from a single‑vendor dependency toward a multi‑model orchestration strategy that routes workloads to the model best suited by task, cost, latency, or compliance needs. Background Microsoft 365 Copilot launched as a tightly integrated AI assistant...

Windows 10 will stop receiving security and feature updates on October 14, 2025 — a firm, calendar‑backed deadline that forces a practical decision for millions of home users and small businesses: upgrade now, buy time with paid options, replace hardware, move to another OS, or accept rising risk. Background / Overview Microsoft announced that Windows 10 support ends on October 14, 2025, and after that date the company will no longer provide technical assistance, feature updates or security...

Microsoft will cease support for Windows 10 on October 14, 2025 — a hard cutoff that leaves school networks, peripheral systems and forgotten classroom PCs increasingly attractive to attackers unless institutions act quickly to upgrade, isolate, or buy into Microsoft’s paid Extended Security Updates (ESU) while they plan a staged migration to modern hardware and Windows 11. Background Windows 10 has been the dominant classroom OS for most education systems worldwide for the better part of...

Microsoft’s decision to end routine security and feature updates for Windows 10 on October 14, 2025 has transformed a long‑announced lifecycle event into an urgent, practical crisis for millions of users — a hard deadline that forces households, schools, small businesses and public institutions to choose between upgrading to Windows 11, buying new hardware, buying a short‑term security bridge, or continuing to run increasingly vulnerable systems. Background / Overview Windows 10 debuted in...

Microsoft has quietly pushed out PowerToys v0.94.2 to stamp out a stubborn installer regression that left some users unable to upgrade or install the utility suite from GitHub, winget, or the Microsoft Store, restoring a critical path for distribution and deployment. Background PowerToys has evolved from a nostalgic power-user toolkit into a polished, actively maintained set of utilities for Windows 10 and Windows 11. Recent months have seen a steady cadence of releases focused on UI polish...
