Van toepassing op:
✓ Windows 10
✓ Windows 11

Feature updates = major changes: Feature update: Semi-annual (22H2, 23H1) - new features, UI changes, driver updates, Risks: Breaking changes (app compatibility, driver issues), Early adopter problems (bugs in new features), Business impact: Productivity loss (broken apps, user retraining). Deferral benefits: Microsoft testing: 180 days → millions of early adopters find bugs → Microsoft patches, Enterprise testing: Pilot group tests deferred update → app compatibility verification → production rollout. CIS recommendation: 180+ days deferral (balance: stability vs security).

PowerShell Modules Vereist
Primary API: Microsoft Graph API
Connection: Connect-MgGraph
Required Modules: Microsoft.Graph.DeviceManagement

Implementatie

Defer feature updates: 180 days: Production devices receive feature updates 6 months after release, Quality updates: NOT deferred (security patches immediate), Pilot group: 0-30 days deferral (early testing), Production: 180 days (stability), Deployment rings: Pilot (IT - 0 days) → Early adopters (30 days) → Production (180 days).

Vereisten

  1. Intune subscription
  2. Windows 10/11
  3. Deployment rings: Pilot + Production groups
  4. App compatibility testing process

Implementatie

Intune: Devices → Windows Updates → Update rings → Create ring 'Production' → Feature update deferral: 180 days, Quality update deferral: 0 days (immediate security patches). Assign to: Production devices. Pilot ring: 0-30 days deferral (IT team).

Compliance

CIS Windows Benchmark (180 days), BIO 12.06 (Change management), ISO 27001 A.12.6.1.

Monitoring

Gebruik PowerShell-script windows-update-defer-feature.ps1 (functie Invoke-Monitoring) – Controleren.

Remediatie

Gebruik PowerShell-script windows-update-defer-feature.ps1 (functie Invoke-Remediation) – Herstellen.

Compliance & Frameworks

Automation

Gebruik het onderstaande PowerShell script om deze security control te monitoren en te implementeren. Het script bevat functies voor zowel monitoring (-Monitoring) als remediation (-Remediation).

Management Samenvatting

Defer feature updates: 180 days (production). Pilot: 0-30 days (testing). Quality updates: Immediate (security). Stability over bleeding-edge. Implementatie: 3-13 uur.
