wintoast pops native Windows toast notifications from plain Ruby scripts using the WinRT notification API that ships with Windows — no Windows App SDK, no packaging, no COM activation server, no elevation — and drives progress on the taskbar button (ITaskbarList3) and the Windows Terminal tab (OSC 9;4) at the same time, so progress shows up under classic conhost AND modern terminals. API: Wintoast.toast (title/body/attribution, app logo + hero images, system sounds, duration, scenario, expiration, tag/group), Wintoast.register! / unregister! (opt-in, reversible, per-user HKCU AppUserModelId branding — no shortcut, no admin), Wintoast.progress / progress_clear, and Wintoast::Payload.build for inspecting the exact toast XML. Windows MSVC (mswin) Ruby only.
