Win11 Hardening
Secure your Windows 11 in 3 clicks. No CLI. Nothing breaks.
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.
Hey Product Hunt 👋
I built Win11 Hardening because every hardening tool I tried sat at one of two extremes — consumer privacy toggles with no Defender / Firewall / ASR coverage, or Microsoft's Security Baseline GPO pack that's unusable on a non-domain home machine.
Win11 Hardening sits in the middle. Plain-English UX for humans, enterprise-grade coverage under the hood. Every rule maps to a published baseline (CIS Win11 v3.0.0, MS Security Baseline 24H2, ANSSI), and you can verify each one against the source document.
Three things I'd love your reaction to:
1. It's reversible. Per rule. From the GUI. One click.
2. It re-tests itself after applying. If a rule didn't actually take effect, automatic rollback. No silent partial states.
3. It catches Windows Update drift — a scheduled task re-runs your rules after each cumulative update and banners you on next boot if Microsoft re-enabled something. I haven't seen another Windows hardening tool do this.
Stack: Go 1.26 + Wails 2 + PowerShell 5.1. 98 Pester + 100+ Go tests, property-based + fuzz + gosec in CI. Reproducible build, SHA256 published. 100% local — zero network call at runtime. WTFPL license. EN / FR.
Honest comparison vs. O&O ShutUp10++, Privatezilla, ChrisTitus WinUtil and MS Baseline is in the README — happy to discuss where it's weaker.
Would love feedback on the manifest format, the drift-detection model, and what to prioritize next (BitLocker / TPM coverage is where ANSSI is 0currently thin).
