The simple multi-theading code is above and does work as I explained earlier.

But I wanted something more 'stable', (1) for example the file name doesn't work with spaces:

"C:\Users\Adrian\Desktop\multi theading\multi.bat" - doesn't work.

"C:\Users\Adrian\Desktop\multitheading\multi.bat" - works.

(2) How do I get it to support multiple arguments?

[code]
if not "%1" == "" echo(

start /b %~nx0 checkcalcDurationReg /d /r
echo Running simulation
pause

:checkcalcDurationReg
echo Running new process
set "/d="&set "/r="
for %%a in (%*) do (
  if "%%~a"=="/d" ( set "/d=true"
   ) else if "%%~a"=="/r" set "/r=true"
)
if defined /d set calcLoadingDurationmode=Enabled
if defined /r (
reg query "%RegKey%" /v "CALC_LOADING_DURATION" >nul 2>nul
if "!errorlevel!"=="0" for /f "tokens=2*" %%i in ('reg query "%RegKey%" /v "CALC_LOADING_DURATION"') do set "calcLoadingDurationmode=%%j"
if "%calcLoadingDurationmode%"=="Enabled" (exit /b
) else if "%calcLoadingDurationmode%"=="Disabled" (exit /b
) else ( >nul reg delete "%RegKey%" /v "CALC_LOADING_DURATION" /f )
call :checkcalcDurationReg /d
>nul reg add "%RegKey%" /v "CALC_LOADING_DURATION" /t REG_SZ /d "%calcLoadingDurationmode%" /f )
echo end of process
exit /b
