Так дали же пример, просто возьми первое слово:

Код:

$oSWbemLocator    = ObjCreate("WbemScripting.SWbemLocator")
$oSWbemServicesEx = $oSWbemLocator.ConnectServer(".", "root\cimv2")

$sManufacturer = ''

For $oSWbemObjectEx In $oSWbemServicesEx.ExecQuery("SELECT Manufacturer FROM Win32_BaseBoard")
    $sManufacturer = StringRegExpReplace($oSWbemObjectEx.Manufacturer, '^([^\h]+).*', '\1')
Next

ConsoleWrite($sManufacturer & @CRLF)

Ну или так:

Код:

#include <Array.au3>

$iPID = Run(@ComSpec & " /C wmic baseboard get Manufacturer", "", @SW_HIDE, $STDOUT_CHILD)
ProcessWaitClose($iPID)
$sOut = StdoutRead($iPID)

$avArray = StringRegExp($sOut, '([^\s]+)', 3)

If Not @error Then
    _ArrayDisplay($avArray)
    MsgBox(0, '', $avArray[1] & @CRLF & "Количество символов: " & StringLen($avArray[1]))
EndIf
