Share Wi-Fi from Windows 10

[Chaudry]

Hi,

so I want to use my Windows laptop as a Wi-Fi router. Here's a writeup on how to share a WiFi connection to other devices, but it require that I download a .bat file and run it as Administrator. I have no clue what a .bat file is, will my anti virus software catch it if it's malicious?
The reason I want to do this from my laptop is to be able to share a VPN connection with my Smart TV.

A .bat file is a "batch" file dating back to early versions of DOS, never mind Windows.

All it is is w list of text commands, but since those can execute program files, it can be dangerous. The good news is they're easy to read to see what they're doing.

Warning - I'm not a W10 user so if .bat files have changed. someone else will point it out.

As for the rest, dunno, never tried it.

Saracen999 is right as bat files can be malicious and cause havok but they are just executable files like EXE or MSI files.

I have had a look at the one you've linked to and it looks safe with the following contents:
@ECHO OFF
netsh wlan set hostednetwork mode=allow ssid=SharedWiFi key=CS9dZZEk
netsh wlan start hostednetwork
ECHO.
ECHO.
ECHO ***** PRESS ANY KEY TO OPEN NETWORK CONNECTIONS SETTINGS *****
ECHO.
ECHO ***** RETURN TO THIS SCREEN AFTER ALLOWING NETWORK SHARING *****
ECHO.
ECHO.
ECHO.
PAUSE
ncpa.cpl
ECHO.
ECHO.
ECHO.
ECHO ***** PRESS ANY KEY TO START WiFi SHARING *****
ECHO.
PAUSE
netsh wlan stop hostednetwork
netsh wlan start hostednetwork
ECHO.
ECHO.
ECHO *****************************************
ECHO * *
ECHO * WiFi network name: SharedWiFi *
ECHO * Password: CS9dZZEk *
ECHO * *
ECHO *****************************************
ECHO.
ECHO.
ECHO.
ECHO ***** PRESS ANY KEY TO STOP WiFi SHARING *****
ECHO.
ECHO.
ECHO.
PAUSE
netsh wlan stop hostednetwork
EXIT
All it does is take the commands which you would normally execute manually in command prompt/Powershell or via the GUI and it has wrapped them up into an easy to run file
