batch file open windows and resize them

Question

I am currently trying to open two windows through a batch file and then resize and move them (to be splitscreen). Opening the separate windows is easy:

@echo off

cd "C:\Program Files (x86)\Internet Explorer"
start iexplore.exe 

cd "C:\Program Files (x86)\Mozilla Firefox"
start firefox.exe 

exit

but I can't find a way to resize and move the windows I am opening. I would prefer not having to use any third party programs. I tried looking through the start /? help menu and don't believe any of the options are of use to me.

Microsoft Windows [Version 10.0.10586]
(c) 2015 Microsoft Corporation. All rights reserved.

C:\WINDOWS\system32>start /?
Starts a separate window to run a specified program or command.

START ["title"] [/D path] [/I] [/MIN] [/MAX] [/SEPARATE | /SHARED]
      [/LOW | /NORMAL | /HIGH | /REALTIME | /ABOVENORMAL | /BELOWNORMAL]
      [/NODE <NUMA node>] [/AFFINITY <hex affinity mask>] [/WAIT] [/B]
      [command/program] [parameters]

    "title"     Title to display in window title bar.
    path        Starting directory.
    B           Start application without creating a new window. The
                application has ^C handling ignored. Unless the application
                enables ^C processing, ^Break is the only way to interrupt
                the application.
    I           The new environment will be the original environment passed
                to the cmd.exe and not the current environment.
    MIN         Start window minimized.
    MAX         Start window maximized.
    SEPARATE    Start 16-bit Windows program in separate memory space.
    SHARED      Start 16-bit Windows program in shared memory space.
    LOW         Start application in the IDLE priority class.
    NORMAL      Start application in the NORMAL priority class.
    HIGH        Start application in the HIGH priority class.
    REALTIME    Start application in the REALTIME priority class.
Press any key to continue . . .

If you have PowerShell installed (and you likely do), you can use user32.dll to move and adjust windows. Once upon a time, I needed a script for work that does exactly what you need and I found this and adjusted it to suit my needs. I then used this to convert it to a batch/powershell hybrid so that I only had to double-click the file to get the PowerShell script to run.

@echo off
setlocal
cls
set "POWERSHELL_BAT_ARGS=%*"
if defined POWERSHELL_BAT_ARGS set "POWERSHELL_BAT_ARGS=%POWERSHELL_BAT_ARGS:"=\"%"
endlocal & powershell -NoLogo -NoProfile -Command "$_ = $input; Invoke-Expression $( '$input = $_; $_ = \"\"; $args = @( &{ $args } %POWERSHELL_BAT_ARGS% );' + [String]::Join( [char]10, $( Get-Content \"%~f0\" ) ) )"
goto :EOF

    [Win32]::MoveWindow($browser, $screen_x, $screen_y, $win_x, $win_y, $true)
}

MoveAndResize "InternetExplorer"
MoveAndResize "Firefox"

Note that I'm using the Program Files version of iexplore instead of the Program Files (x86) version because that one wouldn't move or resize for some reason.
