Start
Starts a separate Command Prompt window to run a specified program or command. Used without parameters, start opens a second command prompt window.
Syntax
start ["title"] [/dPath] [/i] [/min] [/max] [{/separate | /shared}] [{/low | /normal | /high | /realtime | /abovenormal | belownormal}] [/wait] [/b] [FileName] [parameters]
Parameters
" title " : Specifies the title to display in Command Prompt window title bar.
/d Path : Specifies the startup directory.
/i : Passes the Cmd.exe startup environment to the new Command Prompt window.
/min : Starts a new minimized Command Prompt window.
/max : Starts a new maximized Command Prompt window.
/separate : Starts 16-bit programs in a separate memory space.
/shared : Starts 16-bit programs in a shared memory space.
/low : Starts an application in the idle priority class.
/normal : Starts an application in the normal priority class.
/high : Starts an application in the high priority class.
/realtime : Starts an application in the realtime priority class.
/abovenormal : Starts an application in the abovenormal priority class.
/belownormal : Starts an application in the belownormal priority class.
/wait : Starts an application and waits for it to end.
/b : Starts an application without opening a new Command Prompt window. CTRL+C handling is ignored unless the application enables CTRL+C processing. Use CTRL+BREAK to interrupt the application.
FileName : Specifies the command or program to start.

Remarks
You can run nonexecutable files through their file association by typing the name of the file as a command. For more information about creating these associations in a command script by using assoc and ftype, see Related Topics.
When you run a command that contains a the string "CMD" as the first token without an extension or path qualifier, "CMD" is replaced with the value of the COMSPEC variable. This prevents users from picking up cmd from the current directory.
When you run a 32-bit graphical user interface (GUI) application, cmd does not wait for the application to quit before returning to the command prompt. This new behavior does not occur if you run the application from a command script.
When you run a command that uses a first token that does not contain an extension, Cmd.exe uses the value of the PATHEXT environment variable to determine which extensions to look for and in what order. The default value for the PATHEXT variable is: .COM;.EXE;.BAT;.CMD (that is, the syntax is the same as the PATH variable, with semicolons separating the different elements).
When you search for an executable and there is no match on any extension, start searches directory name. If it does, start opens Explorer.exe on that path.
Examples
To start the Myapp program at the command prompt and retain use of the current Command Prompt window, type:
start myapp
