How to restart batch file itself?

How to restart batch itself automatically?
If the filename of batch changed,
start <fixedbatchfilename>
must fail because though the filename changes, the command doesn't.
Is there a feasible way, like
start <autogetbatchfilenameitself> ?

why would the file name change?

@Keltari Maybe end-user will change the filename, so the batch file will become invalid

Also on the subject of restarting a batch file generally, you can put a label at the top like :begin then a line anywhere that says goto begin

You can call %0 in the same directory to call the batch itself again.
Here is a little batch-file to see the variables for yourself:
@echo off
echo Filename exactly as called: %0
echo Driveletter: %~d0
echo Path: %~p0
echo Filename: %~n0
echo Extension: %~x0
echo Complete: %~d0%~p0%~n0%~x0
Example:
echo The following will cause this to loop until Ctrl+C is pressed:
%0
Or:
echo The following will cause this to loop until Ctrl+C is pressed:
%~d0%~p0%~n0%~x0

start "" "%~f0" OR start "title of batch window" "%~f0"
To restart a batch file use:
start "" "%~f0"
exit
This will start your batch file from within your batch file, regardless of file name or location, so long as the name or location has not changed during batch operation, IE after batch has started and before code: (start "" "%~f0") has had a chance to execute.
Always include a TITLE this can be a simple string like "My Script" or just a pair of empty quotes ""
According to the Microsoft documentation, the title is optional, but depending on the other options chosen you can have problems if it is omitted.

the other answer gave users the knowledge to build a working answer for themselves, not the answer itself. As a relatively new user to writing cmd batch files I struggled to wright code that would work as intended as I lacked simple knowledge like using quotation marks around fully qualified path names.

What are you talking about?%0and%~d0%~p0%~n0%~x0are complete, ready-to-use solutions. OK, you made the trivial improvement of replacing%~d0%~p0%~n0%~x0with%~f0, which seems to be equivalent. Trivial abbreviations do not qualify as new answers. The big change you introduced was thestartcommand, but why? You can run a batch file just by saying its name; you don't need to usestart.

What are you talking about?
%0 and %~d0%~p0%~n0%~x0 are complete, ready-to-use solutions. OK, you made the trivial improvement of replacing %~d0%~p0%~n0%~x0 with %~f0, which seems to be equivalent. Trivial abbreviations do not qualify as new answers. The big change you introduced was the start command, but why? You can run a batch file just by saying its name; you don't need to use start.– Scott

I didn't know you could run a batch file just by saying its name, I now understand the first answer, and see that
%0 is the best solution.– The Wizerd

@Keltari Maybe end-user will change the filename, so the batch file will become invalid

Also on the subject of restarting a batch file generally, you can put a label at the top like :begin then a line anywhere that says goto begin
