Is there a specific reason for not using PowerShell as it would certainly be much easier?  I have written text replacement utilities for cmd.exe in the past, they compiled utilities though.  Functionality to achieve this is baked in to PowerShell.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Try this batch file:
@echo off
if "%~1"=="" echo Usage: %0 filename.txt & exit /b
if not exist "%~1" echo Cannot find file & exit /b

set /p line=<"%~f1"
echo.%line:~14%>"%temp%\%~nx1.tmp"
more +1 "%~f1">>"%temp%\%~nx1.tmp"
move "%temp%\%~xn1.tmp" "%~f1""

Open in new window

NOTE: Copy & Paste the code into Notepad and save it as a .BAT file. Run the batch file specifying a filename as a command line parameter like this:

    BATCHFILE filename.txt

Where 'BATCHFILE' is the name of your batch file and 'filename.txt' is the name of your text file.

Do you want to remove the 14 characters from the file NAME, or from the file CONTENTS?

If CONTENTS, then do you want to remove the first 14 characters from just the first line, or every line?

while(<*.dat>) {
    open(IN, $_) or die ("Cannot open $_: $!");

I've requested that this question be closed as follows:

Accepted answer: 0 points for decoded's comment #37858196

for the following reason:

Most reliable way to do it...doesn't cause orginal file to get damage. With my sloution it creates a new simple file.

In my comment (http:#37800187) above where I wrote:

Did a comment ID37782035 get deleted or something, or did I missquote the comment ID number?

Did my solution in http:#37788226 (above) not work then?

Incidentally, you didn't say anything about not overwriting the original file. You actually stated:
...is there a way to edit/erase this first 14 characters...
Using the relevent lines of code from my comment above, and omiting the last line (Line 8), you would end up with a new file named 'new-filename' (whatever your filename is). Please see the code below:
@echo off
if "%~1"=="" echo Usage: %0 filename & exit /b
if not exist "%~1" echo Cannot find the file %~1 & exit /b
set /p line=<"%~f1"
echo.%line:~14%>"new-%~nx1"
more +1 "%~f1">>"new-%~nx1"

Open in new window

I also feel this question, and solution has value. It's not something that crops up frequently enough to justify discarding.

I feel a little bit cheated as decoded has moved the goalposts without prior notice, and after a working solution to the question had already been submitted.
