Oliver Kieselbach acf4d0eeaa bootstrap(dev): v2.3-dev.2 - Cloud PC detection on captured evidence
First W365 field test (2026-08-06) proved the assumed WMI signature wrong:
a real Cloud PC reports the generic Manufacturer='Microsoft Corporation' +
Model='Virtual Machine'; the 'Cloud PC Enterprise ...' string exists only in
Intune/Graph inventory. Probe on the live Cloud PC captured two local
markers instead: HKLM\SOFTWARE\Microsoft\Windows365 and the
CloudManagedDesktopExtension service (W365 management agent).

Get-CloudPcModel is replaced by Test-IsCloudPc requiring BOTH markers (each
alone has look-alikes: W365-Boot physical clients / legacy managed-desktop
agents). Raw identity and both marker states are always logged. Tests
updated to the marker model (26 tests, green under PS 5.1 and pwsh 7).

.SYNOPSIS
DEV bootstrap script (v2.3-dev) to deploy and start the Autopilot Monitor agent.
.DESCRIPTION
DEV VARIANT of Install-AutopilotMonitor.ps1 for validating the v2.3 Cloud-PC-relax
on Windows 365 before promoting it to the production script. Differences to v2.2:
- Cloud-PC-relax (see below) as a second trigger for the guard 2+3 exemption
- Raw OutOfBoxExperienceState value is logged (diagnosis)
- Logs to bootstrap_agent_dev.log so runs never interleave with the prod script
- Testable structure: guard/relax logic lives in functions; the script only
executes when run directly. Dot-sourcing it (as the Pester suite in
Install-AutopilotMonitor-dev.Tests.ps1 does) loads the functions without
side effects.
Designed to be deployed via Intune as a PowerShell Script during Autopilot.
Runs very early in the enrollment process (first Intune action) and:
1. Runs pre-flight guards to skip productive devices and ghost re-installs.
A relax exemption allows install when a single freshly-created profile
appears DURING OOBE (Windows Backup for Organizations restore) or on a
freshly provisioned Windows 365 Cloud PC.
2. Downloads the monitoring agent ZIP from Azure Blob Storage
3. Verifies integrity via SHA-256 hash from the version manifest (mandatory)
4. Extracts the agent into %ProgramData%\AutopilotMonitor\Agent
5. Runs the agent in --install mode (registers Scheduled Task, spawns the runtime)
6. Verifies the runtime process actually launched
Agent self-destructs when enrollment completes.
Relax flow (guards 2+3): a real user profile (or a real LastLoggedOnUser)
normally means "productive -> skip". Two legitimate flows break that assumption:
(1) Windows Backup for Organizations: one user signs in + restores DURING OOBE.
Trigger: the OS positively reports OOBE InProgress (Test via WinRT
SystemSetupInfo.OutOfBoxExperienceState).
(2) Windows 365 Cloud PC: W365 provisions headless -- OOBE and Intune enrollment
complete before any user ever connects, so OutOfBoxExperienceState is NEVER
InProgress when this script runs. The assigned user's profile is created at
first connect, typically seconds before IME pulls this script. Trigger: the
device positively identifies as a Cloud PC via TWO local markers (both
required; captured from a real Cloud PC -- local WMI reports only the
generic 'Virtual Machine' model): HKLM\SOFTWARE\Microsoft\Windows365
registry key AND the CloudManagedDesktopExtension service.
Either trigger relaxes guards 2+3 ONLY when additionally:
(a) there is exactly ONE real user profile, AND
(b) that profile was created within $OobeProfileMaxAgeMinutes minutes.
Any miss keeps the original skip (SKIP-safe: we never install on uncertainty).
On productive devices the profile is old, so (b) keeps skipping correctly.
Known accepted edge: a W365 Frontline shared-mode device can legitimately show a
single fresh profile while productive; a mis-install there is one-time (agent
finds enrollment complete and self-destructs; Deployed marker prevents repeats).
.PARAMETER AgentDownloadUrl
URL to download the agent ZIP from. Defaults to the production download endpoint;
override only for parallel lab/dev assignments that point at a separate pre-release ZIP.
.PARAMETER VersionJsonName
Filename of the integrity manifest in the same blob container as the agent ZIP.
Defaults to "version.json"; override only for parallel lab/dev manifests.
.PARAMETER MaxBootstrapWindowHours
Maximum device uptime (hours) within which the bootstrap is still considered
valid. Devices booted more than this many hours ago are skipped because we no
longer trust their OOBE state. Default: 12.
Cloud PC note: a Cloud PC may run for days between provisioning and the user's
first connect; this guard then skips INTENTIONALLY -- the enrollment finished
long ago and there is nothing left to monitor.
.PARAMETER OobeProfileMaxAgeMinutes
Maximum age (minutes) of the single profile that may appear for the relax
exemption to apply. The restore/first-connect -> bootstrap gap is always
minutes; an older profile is treated as a productive device. Default: 15.
.NOTES
- Agent is temporary and auto-removes after enrollment.
- All files live under C:\ProgramData\AutopilotMonitor (easy cleanup).
- One registry key remains after removal: HKLM\SOFTWARE\AutopilotMonitor\Deployed
(prevents ghost re-installs on re-Autopilot of the same device).
- Scheduled Task survives reboots during enrollment.
- OOBE detection uses Windows.System.Profile.SystemSetupInfo.OutOfBoxExperienceState.
Requires Windows 10, version 1809 (introduced in 10.0.17763.0). Older builds lack
the class -> state reads as 'Unavailable' -> original (skip) behaviour. Docs:
https://learn.microsoft.com/en-us/uwp/api/windows.system.profile.systemsetupinfo
- This script MUST remain pure ASCII (no Unicode/UTF-8 special chars).
PowerShell 5.1 (IME) reads scripts without BOM as ANSI, corrupting multi-byte chars.
.CHANGELOG
2026-08-06 v2.3-dev.2 Cloud PC detection rebuilt on captured evidence: first field
test proved local WMI reports only Manufacturer='Microsoft
Corporation' + Model='Virtual Machine' (the 'Cloud PC ...' model
string exists only in Intune/Graph). Detection now requires the
HKLM\SOFTWARE\Microsoft\Windows365 registry key AND the
CloudManagedDesktopExtension service (both verified present on a
real Cloud PC); raw identity + marker states are always logged.
2026-08-05 v2.3-dev DEV variant (-dev.ps1, own log file bootstrap_agent_dev.log)
to validate on Windows 365 before promotion to v2.3:
Cloud-PC-relax -- a positively identified Cloud PC
(Win32_ComputerSystem Manufacturer 'Microsoft Corporation' +
Model 'Cloud PC*') now triggers the guard 2+3 relax alongside
OOBE InProgress; the single-fresh-profile conditions are
unchanged. Raw OutOfBoxExperienceState is now logged.
Refactored into functions with a dot-source entry guard so the
Pester suite (*.Tests.ps1) can load the logic without executing
the bootstrap; behaviour when run directly is unchanged.
2026-07-20 v2.2 Switched default download endpoint from the legacy blob
(autopilotmonitor.blob.core.windows.net) to the Front Door alias
https://download.autopilotmonitor.com/agent/ (route /agent/*).
version.json is still derived from the same container.
2026-06-25 v2.1 OOBE-relax: detect genuine OOBE via WinRT
SystemSetupInfo.OutOfBoxExperienceState and exempt guards 2+3 when a
single freshly-created profile appears in OOBE (Windows Backup for
Organizations). SKIP-safe when the API is absent (< 1809).
Removed legacy Content-MD5 fallback; SHA-256 manifest verification is
now mandatory (no hash -> bootstrap aborts, no unverified install).
2026-05-09 v2.0 Generic bootstrap: agent owns its own defaults (e.g. 600 s
TenantId-wait), so the script only calls `--install` plain.
Hardened post-install with a 10 s runtime-process verify.
