Optional Telemetry Event for Microsoft Store Catalog Installs (msstore Source)

[shmuelie]

📖 Description

Adds an optional telemetry event that lets Microsoft Store analytics attribute Store‑catalog
app installs that happen through WinGet.

When WinGet successfully installs an app whose source is the Microsoft Store (msstore), it now
emits a StoreExperienceTelemetry-WinGetInstall event on the Microsoft-Windows-Store ETW
provider ({9C2A37F3-E5FD-5CAE-BCD1-43DAFEEE1FF0}). The event carries only the minimum needed for
attribution:

Field	Value
pid	Store product ID (the msstore package identifier)
src	Install caller
cn	Catalog name — constant "msstore"

Key points:

• Emitted only on success, only for msstore. The call site is the success path of
  ReportInstallerResult, gated on
  PackageVersion->GetSource().IsWellKnownSource(WellKnownSource::MicrosoftStore). Local‑manifest
  installs (which have no PackageVersion) are guarded with Contains(...) so they are unaffected.
• Scope: unpackaged (Win32) Store apps. Unpackaged msstore items resolve to a real installer
  type (exe/msi) and flow through ReportInstallerResult, so they emit the event.
• New dedicated provider. Microsoft-Windows-Store is registered alongside the existing WinGet
  provider, with its own enablement callback (g_IsStoreTelemetryProviderEnabled) so the Store
  event can be captured independently of the WinGet telemetry provider.
• Privacy‑preserving. The event honors the WinGet telemetry opt‑out
  (m_isSettingEnabled), the runtime toggle (m_isRuntimeEnabled), and initialization state, and
  is tagged PDT_ProductAndServicePerformance / MICROSOFT_KEYWORD_CRITICAL_DATA. It records no
  executable paths, usernames, or command‑line arguments.

🔍 Validation

• CLI, unpackaged Store app (confirmed): winget install XPFFH613W8V6LV --accept-package-agreements (OBS Studio — an unpackaged exe Store app). An ETW capture of the
  Microsoft-Windows-Store provider showed StoreExperienceTelemetry-WinGetInstall with pid =
  the Store product ID and cn = msstore.
• Negative cases: no event for non‑msstore sources, and none for a failed install (the event
  is only reached on the success path).
• Privacy: event is suppressed when WinGet telemetry is disabled via settings or the runtime
  toggle.
