      I believe this will do what you want. Please let me know if you need anything else.

      @ECHO OFF
setlocal enabledelayedexpansion

SET /P maxlines=Enter number of lines to be moved to new txt document: 
SET /A linecount=0

FOR /F "delims=" %%A IN (textfile1.txt) DO ( 
  IF !linecount! GEQ %maxlines% GOTO ExitLoop
  ECHO %%A >> C:\users\username\desktop\textfile2.txt
  SET /A linecount+=1
)

:ExitLoop
ECHO All Done.
ECHO.
ECHO Press any key to close this window.
PAUSE>NUL
EXIT

      UPDATE: Notice I updated Line 4 of my code. I made a mental note to fix it before posting, but forgot. All I did was add a ‘:’ with a space after it so when you type in the number while running the batch file it looks cleaner.
