+# Installed software (the "Add/Remove Programs" / "Apps & features" list).
+# We enumerate the Uninstall registry keys directly — the same source
+# Settings reads — rather than `Get-CimInstance Win32_Product`, which is
+# notoriously slow (triggers MSI self-repair on every entry) and only
+# covers MSI-installed software, missing everything from per-user
+# installers, Chocolatey/Scoop/Inno-Setup, etc.
+#
+# We read both HKLM hives (64-bit + WOW6432Node 32-bit) so apps installed
+# under either bitness show up. HKCU is skipped on purpose: the agent
+# runs as LocalSystem (or LocalService), whose HKCU hive has nothing the
+# logged-in user installed under their own profile — that data would
+# require running per-user, which is out of scope for v1.
+#
+# Filter rules:
+#   * `DisplayName` must be set — empty-DisplayName entries are uninstall
+#     stubs for individual update KBs and not user-facing apps.
+#   * Skip `SystemComponent = 1` — internal Windows components hidden
+#     from Settings (DirectX shims, VC++ private redists, …).
+#   * Skip entries with a `ParentKeyName` — those are subcomponents of a
+#     parent application (e.g. Office's per-language packs); the parent
+#     row already covers the user-facing app.
+#
+# Bitness-tagged so the admin UI can distinguish a 64-bit vs 32-bit
+# install of the same product (common for runtimes like VC++).
