autostart-run.bat did 'cd /d %~dp0' -> scripts/, but web-vnc.exe/webvnc.conf/ go.mod live in the repo root, so the binary was never found and web-vnc never started after reboot. Now it cd's to %~dp0.. (repo root). The task was ONSTART/RU SYSTEM (session 0) so it could not show a window, making failures invisible. install-autostart.bat now registers ONLOGON /RL HIGHEST as the current user -> a visible console opens at logon. autostart-run.bat sets a window title, prints status, stays open while web-vnc serves, and pauses on fatal errors (no binary / no webvnc.conf) so the reason is visible. Docs updated.

REM ============================================================
|
|
REM autostart-run.bat - launcher used by the scheduled task
|
|
REM created by install-autostart.bat. Runs in a VISIBLE console
|
|
REM window (install-autostart.bat registers it at logon, as the
|
|
REM current user, so the window is visible - unlike a hidden
|
|
REM SYSTEM/boot task). It reads the password from webvnc.conf,
|
|
REM WAITS for the VNC server on 127.0.0.1:5900 (the UltraVNC
|
|
REM service may still be starting), and only then starts
|
|
REM web-vnc.exe in the foreground. If no VNC server comes up,
|
|
REM it spawns a local one. On any fatal error it pauses so the
|
|
REM window stays open and you can read why it did not start.

REM This script lives in scripts/ but operates relative to the

REM there), so it cd's to %~dp0.. first.
