+The app and installer are statically linked against the MSVC CRT (`/MT`); the small startup launcher is CRT-free. The binaries depend only on core Windows DLLs (`kernel32`, `user32`, `gdi32`, `shell32`, `setupapi`, `hid`, `advapi32`, `comctl32`, `ole32`). The icon is regenerated from `assets/generate-icon.ps1` if missing.
 
 ## Troubleshooting
 
 **The tray icon shows "unavailable" and the menu has nothing useful.**
 Run `SuperLightBattery.exe --probe` from a terminal. It will list which Logitech HID collections are detected and which (if any) answer HID++. Make sure the receiver is plugged in and the mouse is paired and on.
 
-**A console window flashes when I run `SuperLightBattery.exe --tray` directly.**
-The tray binary is a console-subsystem app; the autostart entry hides the console by going through `SuperLightBatteryInstaller.exe --launch-tray`, which spawns the tray with `CREATE_NO_WINDOW`. For a console-free manual launch, use the installer or `--launch-tray`.
+**Why are there two app executables?**
+`SuperLightBattery.exe` is the real tray and CLI app. `SuperLightBatteryLauncher.exe` is the tiny windowless startup launcher shown by Startup Apps.
 
 **Icon looks blurry on a high-DPI display.**
 The tray icon renders at the shell's requested pixel size with 4× supersampling and is per-monitor DPI aware. If it still looks soft, open an issue and include your DPI scaling (Settings → System → Display → Scale).
 
-**Installer says "SuperLightBattery.exe must sit next to the installer."**
-The two executables need to be in the same folder. The release zip ships them that way already; re-download the full archive if they got separated.
+**Installer says a SuperLightBattery file must sit next to the installer.**
+The tray/CLI app, startup launcher, and installer need to be in the same folder. The release zip ships them that way already; re-download the full archive if they got separated.
 
 **Tray won't exit during uninstall.**
 The installer posts `WM_CLOSE` to the tray window and waits briefly. If the tray was unresponsive at that moment, exit it manually from its right-click menu and run uninstall again. The locked files were already scheduled for deletion at next reboot.
