QtCreator is not fully handling command line parameters. 

Those are opening new dialog:

  PS C:\Qt\Tools\QtCreator\bin> .\qtcreator.exe -help     Open help dialog.
  PS C:\Qt\Tools\QtCreator\bin> .\qtcreator.exe -version  Open a version dialog

Thoses are starting QtCreator without executing profile or blocking until QtCreator ends:

  PS C:\Qt\Tools\QtCreator\bin> .\qtcreator.exe -profile  
  PS C:\Qt\Tools\QtCreator\bin> .\qtcreator.exe -block
  PS C:\Qt\Tools\QtCreator\bin>

I expect `-block` option to block the shell until QtCreator applicaiton is close; this is the case under Linux with QtC 4.13.2.
