Customer field case: pre-provisioned devices with the ConfigMgr client as a
blocking app occasionally park the user ESP at "Apps (Identifying)" for days.
Root cause (verified against the EnrollmentStatusTracking CSP doc): only a
"ConfigMgr" provider is registered under Device\Setup\Apps\PolicyProviders
(no "Sidecar" = IME) and TrackingPoliciesCreated never becomes 1 - a wait the
CSP defines WITHOUT any timeout. Renaming the key to Sidecar unblocks
immediately. Microsoft documents that ESP providers are not aware of each
other and that pre-provisioning is unsupported with co-management.
New always-on esp_policy_provider_stalled tripwire, generalized to any
provider in both kinds (Setup/Apps TrackingPoliciesCreated != 1,
DevicePreparation InstallationState not in {2,3}):
- EspPolicyProviderProbe: fail-soft registry read of the
EnrollmentStatusTracking mirror (device + user-SID scopes), defensive
value parsing (missing/unparseable = incomplete), ScopedOverride test seam.
Research and CSP contract quotes captured in the XML doc header.
- EspPolicyProviderStallDetector: pure EvaluateStallTransition on a 15-min
continuous-incompleteness dwell (resets on completion/disappearance;
absent key = normal early enrollment), one-shot per provider,
StartupEventGate fingerprint over the sorted stalled key set for
cross-restart dedup. Warning + ImmediateUpload via InformationalEventPost;
purely observational, no decision-engine coupling, no config toggle,
no ConfigVersion bump (disk_space_low precedent).
- EspPolicyProviderStallHost: 60-s wall-clock tick, deliberately outside the
StallProbe idle gate (idle clock resets on session activity) and the
idle-stopped periodic collectors.
- Registered in Constants.EventTypes, MCP resource-catalog (health_events),
web gather-rule autocomplete (stall category).
Guardrail companion: SOFTWARE\Microsoft\Windows\Autopilot joins the
gather-rule registry allowlist ("Autopilot / OOBE / Setup") so tenants can
build custom rules on the subtree (e.g. not_exists on the Sidecar provider
key); generated web mirror regenerated via combine.js; positive + sibling-
spoof guard tests added.
Docs: OKF concept doc agent/esp-policy-provider-stall.md (+ index/log).
Tests: 22 new detector tests (pure transition matrix + emission surface incl.
the ConfigMgr-only customer scenario and gate-across-restart dedup); agent
suite 2013/2013, web vitest 589/589 + tsc clean, MCP 449 passed incl.
event-types-drift.
Both the detector and the embedded allowlist take effect with the next agent
release.

Overview
Autopilot Monitor provides real-time tracking, intelligent diagnostics, and automated troubleshooting for Windows Autopilot enrollment processes. It consists of:
- Bootstrap Script — PowerShell script deployed via Intune that starts monitoring early in the enrollment process
- Monitoring Agent — Lightweight .NET application that collects telemetry and evidence during enrollment
- Backend API — Azure Functions-based ingestion and processing pipeline
- Web Dashboard — Next.js application for real-time monitoring and fleet analytics
