I created this batch and i tested it on my Windows 10 and it works 5/5
@echo off
Set "MyTitle=FullScreen"
Title %MyTitle% & color 0A & cls & cd %temp%
set "vbsfile=%~n0.vbs"
echo >"%vbsfile%" set shell = CreateObject("WScript.Shell"):shell.SendKeys "{F11}"
REM Timeout /t 1 /nobreak>NUL
Wscript.exe "%vbsfile%"
Ipconfig /all
pause
And here is another batch that can use this as sub to be called when you want to fullscreen or come to the back to normal screen :
@echo off
REM Here we call the sub :FullScreen to make it fullscreen
Call :FullScreen
Ping www.google.com
Tracert www.google.com
Call :FullScreen REM You come to the normal when we call it again the sub :FullScreen
ipconfig /all
Pause & Exit
REM -------------------------------------------------------------------------------
:FullScreen
Set "MyTitle=FullScreen"
Title %MyTitle% & color 0A & cls & cd %temp%
set "vbsfile=%~n0.vbs"
echo >"%vbsfile%" set shell = CreateObject("WScript.Shell"):shell.SendKeys "{F11}"
REM Timeout /t 1 /nobreak>NUL
Wscript.exe "%vbsfile%"
Exit /b
REM -------------------------------------------------------------------------------
