Implementatie
2u (tech: 1u)
Van toepassing op:
✓ Windows 10
✓ Windows 11

Windows Insider = BETA software: Preview builds: Pre-release Windows features (unfinished code), Risks: System crashes (blue screens), Data corruption, Application incompatibility, Performance issues, Privacy: Telemetry collection (extensive diagnostic data → Microsoft). Production devices: NEVER run Insider builds (stability required), Test lab: Dedicated Insider devices (isolated testing). User enrollment: Some users join Insider (curiosity) → production device becomes unstable.

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

Implementatie

Disable Insider: Policy: Manage preview builds: Disable preview builds, Effect: Users CANNOT enroll in Windows Insider Program, Insider settings: Grayed out in Windows Settings, Production protection: Only stable GA releases.

Vereisten

  1. Intune subscription
  2. Windows 10/11
  3. Production devices (NOT test lab)

Implementatie

Intune: Windows Update ring → Manage preview builds: Disable preview builds. Effect: Insider enrollment blocked. Test lab: Separate policy (allow Insider) for dedicated test devices.

Compliance
