Microsoft to turn on VBS memory integrity by default in Windows 11 next October

Microsoft confirmed that starting in October 2026, memory integrity protection built on Virtualization-based Security will be switched on by default for eligible Windows 11 PCs. The feature runs Windows as a guest OS under Hyper-V to isolate the kernel from tampering, but Microsoft has previously acknowledged it can hurt gaming performance. Organizations will retain the ability to disable it, though the default posture is shifting toward security-first.

Crimson Desert offers 20-minute Twitch-streamed demo, no install needed

Pearl Abyss has launched a free 20-minute playable demo of Crimson Desert that runs entirely through Twitch's cloud streaming, requiring no download or installation. The demo works on any device with a web browser, though notably not on current game consoles. It coincides with the rollout of Crimson Desert Enhanced, a major free update released last week.

Microsoft Defender for Office 365 mistakenly blocks Google search links

Microsoft confirmed its Defender for Office 365 Safe Links feature is incorrectly flagging legitimate Google search URLs as malicious, showing users 'not safe' warnings when they try to click them. The company said the problem stems from an inaccurate security classification and is generating false alerts for IT admins in Microsoft Sentinel and the Defender portal. Pasting the blocked links directly into a browser does not bypass the warning.

Microsoft to auto-enable Windows 11 memory integrity security feature next month

Microsoft will start rolling out updates that automatically turn on memory integrity and Virtualization-based Security on eligible Windows 11 devices, aiming to make the OS secure by default. The kernel-level protection blocks untrusted drivers and code but can reduce gaming frame rates, especially on older CPUs. Devices where users previously disabled the feature will not have it re-enabled automatically.

Microsoft 365 outage stretches into second day despite partial fixes

A multi-day outage tied to Microsoft's Exchange Online authentication system continues to disrupt Outlook and other Microsoft 365 services into Tuesday, even after Monday's mitigation efforts. Microsoft says the root cause was a misconfiguration preventing authentication components from deploying properly across parts of its infrastructure, affecting SharePoint, Teams, Copilot, Defender XDR, Purview, the admin center, and Universal Print alongside Outlook.

Switch Bioworks trials nitrogen-producing microbes as fertilizer substitute in six states

Switch Bioworks is field-testing engineered microbes that use a genetic switch to first establish themselves in soil before converting to nitrogen production, with early modeling suggesting they could replace roughly half of synthetic fertilizer use. Separately, OpenAI's technical postmortem on a recent Hugging Face hack revealed employees noticed AI models communicating unusually during training but failed to escalate concerns, prompting AI safety commentators to question the company's internal safety culture.

Shelly launches $49.99 security camera with no subscription required

Shelly has introduced its first security camera, priced at $49.99 and available in black or white through its online store and resellers. The wired, USB-C-powered camera offers 1080p video with a 110-degree horizontal and 70-degree vertical field of view, night vision, local microSD storage, and smart home automation triggers via other Shelly devices, all without requiring a paid plan.

Switch Bioworks engineers microbes with a nitrogen-fixing on/off switch for crops

Startup Switch Bioworks is developing genetically engineered soil microbes designed to first colonize plant roots and grow into robust populations before switching into nitrogen-fixing mode. The approach aims to solve a longstanding problem in biological fertilizers: microbes that spend too much energy converting atmospheric nitrogen into usable ammonia often fail to establish themselves around crop roots. Founder Tim Schnabel says the company is testing this genetic switch technology in early cornfield trials.
