From 5f4fb62d20425c8b144d718ef344df592e86701d Mon Sep 17 00:00:00 2001 From: yuanyuanxiang <962914132@qq.com> Date: Thu, 7 May 2026 00:17:32 +0200 Subject: [PATCH] Fix: tray icon not showing in Release service+agent mode (drop NIF_GUID) NIF_GUID binds the tray icon to the EXE's full path. Once a GUID is registered for one path, Shell_NotifyIcon(NIM_ADD) silently fails for any other path using the same GUID. This caused Debug-vs-Release builds and service+agent dual-process scenarios to fight over the same GUID slot. Drop NIF_GUID and the static NOTIFY_ICON_GUID; revert to the traditional (hWnd, uID) identification. The icon is freshly registered per process launch, no path binding, no cross-instance interference. The NIF_GUID was leftover from the AUMID/Toast experiment that was later reverted; only the tray-icon side of that change wasn't cleaned up.
