Modern Management Summit 2026
Paris — The Complete Debrief

The Microsoft Core Security team presented the most urgent change for Windows endpoint admins in 2026: the UEFI Secure Boot certificate rotation. Two critical deadlines — CAT certificate expires June 24, third-party signing certificate expires June 27. The CA 2011 certificate is being replaced by two separate CA 2023 certificates (UFCA 2023) to enable targeted revocation. Microsoft has already auto-updated 50% of the 300 million eligible devices. Devices are classified into confidence buckets (bi-weekly data science ratings) and those in the "high confidence" category receive automatic updates. The session demoed a detection script that outputs a JSON file with 13 data points, an Intune remediation script for mass deployment, and 7 automation scripts for phased rollout. OEM coordination is required for legacy hardware. PQC (Post-Quantum Cryptography) transition and 12 new certificate spectrums are coming by 2027.

Intune's anomaly detection engine (traditional ML models) was fully demoed — covering BSODs, app crashes, severity scoring (high/medium/low), and dynamic device cohort grouping with configurable shelf life. The new multi-device query capability allows cross-tenant hardware inventory queries. Copilot translates natural language to KQL directly in the console, accessing hardware inventory cached in fast/slow streams (P90 within 1 hour). The "Tenup Score" concept was introduced as a composite health KPI. Explorer capability will expand to EPM, advanced analytics, and multi-workload support. Known gap: queries cannot be shared across geographies.

A 15-year Microsoft MVP delivered one of the most practical sessions of the summit. Workflow: collect logs via custom Intune remediation scripts (not the built-in Intune log collection — too slow), then feed into AI tools (Copilot, Security Copilot, ChatGPT, and Claude) for automated root cause analysis. Key demo: a 70MB, 10-minute SCCM log file was analyzed in seconds — identified two missing applications and a race condition. For Win11 upgrades: use "setupdiag" — found insufficient disk space (now requires a 25 GB compliance policy) and incompatible drivers. App Control for Business flagged as high-demand but complex. GitHub Copilot "planning mode" used live to build an analysis tool in minutes.

Hard data opened: enterprise security challenges growing 8× annually, average daily AI usage 60 min/user, 70% YoY growth in AI job postings. Zero Trust reframed as a lifecycle (never-ending cycle) rather than a project. AI agents contrasted with human agents — runs 24/7, task-specific, different identity model. Key announcements: Security Copilot now included in M365 E3/E5. Latency improvements: PNI notifications now under 5 minutes. Multi-admin approval for PowerShell scripts demoed live. AI vulnerability remediation agent (Defender + Intune) automates fix recommendations with human review gate. New EPM dashboard showing elevation activities.

Deepest technical session — Intune's internal check-in model with real numbers. Three check-in types: client-initiated (company portal), device-initiated (login/schedule), change-based (payload/group). WLS replaced by IC3 with 4 priority categories. Key metrics: 20% reduction in notifications, 97% of change operations first attempt, 75% of MDM remediation checks wasted (now eliminated). Compliance state P90 reduced from 252 minutes to 3.7 minutes. iOS: off-peak data requests to Apple. Reporting: 97% of reports migrated to new pipeline, discovered apps from 7 days → 1–3 hours.

Hotpatch (no reboot required, available May 12, 2026): quarterly quality update followed by 2 months of lightweight security-only patches. Identical security fixes to regular B-week updates. Driver management: Graph API for reporting, OEM drivers require up to 45 days validation, two driver types. Dynamic deployment rings: up to 16 rings, percentage-based, with pinning. For Office: Cloud Updates strongly recommended over policy deferral — CDN gradual rollout makes deferral unreliable. Upcoming: individual content pausing, maintenance windows for CSPs, .NET update controls.

Four auth methods compared: device code (PS7, no popup), service accounts, client secrets, and managed identities (preferred). Device code: different UX between PS5 and PS7. Client secrets: 403 behavior — authentication vs authorization distinction. Managed identities: no stored credentials, no expiration, environment variables for cross-team use. Graph API pagination for large data retrieval. Beta vs V1 API risks: beta provides richer data but no support. Chrome DevTools URL capture for identifying Graph endpoints.

Advanced PowerShell + Graph patterns for eliminating portal gaps. Topics: automating app uploads and OS updates, Chrome DevTools URL capture, consolidated reporting from multiple Microsoft portals. Script quality principles: hash tables over long parameters, variable splatting, minimal modules, pagination/throttling handling. New: the "IntoWind" module for advanced Intune operations. Configuration pipeline: JSON backups with timestamps, baseline comparison (23H2 vs 25H2 — acceptable error threshold ≤2). Governance gaps: ungoverned group creation, unassigned policies, scripts without descriptions.
