PUSHD "%~dp0"

But be aware, that you will lose the ability to run such script from different
CWD.

sed "0,/^---BASH SCRIPT FOLLOWS---/ d; s/\r*$//" < "%~f0" | bash

That's nice for desktop application.
But

EXIT %ERRORLEVEL%

would be more useful in general.

And keep in mind: not everything can be run that way, unfortunately.
Only interpreters accepting command stream from STDIN (such as bash).
And you will lose the ability to pipe data to such script yourself.

On a slightly unrelated note, please avoid naming your scripts ".bat", when
you are using extended CMD features. Not every .bat file interpreter supports
a full range of bugs in CMD.
