$WM_QUERYENDSESSION not detected if script running in schedule task

[Efo74]

Hello all,

I'm testing and a little modify a script i found in this forum  for detect and handle a shutdown or reboot event. The script is running fine only if I double click the exe file compiled, but if i create a schedule task /  manually run nothing happends / nothing is logged. is there a way to detect shutdown event in a scheduled script (the scheduled script is running with admin privilege) ?? . In Attachment the script. Thanks in advance for the support.
