to the cmd.exe and not the current environment.

If it is an internal cmd command or a batch file then
the command processor is run with the /K switch to cmd.exe.
This means that the window will remain after the command
has been run.
If it is not an internal cmd command or batch file then
it is a program and will run as either a windowed application
or a console application.
parameters These are the parameters passed to the command/program
When you do, you receive a My Windows Title command windows with the following error:
'C:\Documents' is not recognized as an internal or external command, operable program or batch file.
NOTE: when you use start "%USERPROFILE%\My Documents\test.bat" "P 1" "p 2" "p 3", you receive:
The system cannot find the file P 1.
When you run call "%USERPROFILE%\My Documents\test.bat" "P 1" "p 2" "p 3"
or just "%USERPROFILE%\My Documents\test.bat" "P 1" "p 2" "p 3", the command runs as expected.
To workaround this behavior, you can use the Start command by specifying the /D switch:
start "My Windows Title" /D"C:\%USERPROFILE%\My Documents" test.bat "P 1" "p 2" "p 3"
