  for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value')    do        
set "dt=%%a" 
set "td.YY=%dt:~2,2%" 
set "td.YYYY=%dt:~0,4%"
set "td.MM=%dt:~4,2%"

:loop
for %%i in (%filename%) do (
        echo %%~ai|find "a" >nul && (
        cscript MessageBox.vbs "Today's Schedule Changed. Modified Time: %time%. Please Check AVScheduler ON or OFF."
