Win11 Hardening

What it does

A fresh Windows 11 in 2026 still ships with SMBv1, NTLMv1, WPAD and Defender ASR off. Win11 Hardening is an open-source GUI that explains every security setting in plain English, applies them in one click, and rolls back automatically if a rule didn't take effect. Mapped to CIS, Microsoft Security Baseline and ANSSI. Detects when Windows Update silently re-enables your settings. Reversible per rule. 100% local. Stack: Go + Wails + PowerShell. WTFPL. EN / FR.

Free open-source Windows 11 hardening tool. Plain-English GUI, one-click apply, fully reversible. Maps to CIS Benchmark, Microsoft Security Baseline and ANSSI. Detects Windows Update drift. EN / FR.

A free open-source desktop app that explains every Windows 11 security setting in plain English, applies them with one click, and undoes everything if you change your mind. Built on top of CIS Benchmark, Microsoft Security Baseline and ANSSI recommendations. Not opinion. Microsoft keeps these settings off for backwards compatibility. Windows 11 Hardening flips them, explains why, and lets you undo any of them individually. SMBv1, NTLMv1, WPAD — names that appear in every WannaCry / NotPetya post-mortem. Advertising ID, Bing in Start menu, diagnostic data feeding Microsoft every day. Office still trusts macros from Internet-downloaded documents by default.

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
