Creating an hotspot with windows 7 is easy, but you may have to install some additional software.

If you don’t want to install anything you can write a simple batch file that will do the work.

Simply create a wifihotspot.bat file containig the following two lines:

netsh wlan set hostednetwork mode=allow ssid=<your wifi name> key=<your password>
netsh wlan start hostednetwork


where <your wifi name> is the name you want to assign to your hotspot and <your password> is the password to access to the hotspot.

Now right-click on your bat file and then run it as administrator.

You may also modify the batch file, adding the code to ask for administrator privilegies as shown at

The final code will be:

@echo off

:: BatchGotAdmin
REM --> Check for permissions
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"

REM --> If error flag set, we do not have admin.
if '%errorlevel%' NEQ '0' (

echo Requesting administrative privileges...
goto UACPrompt
) else ( goto gotAdmin )

echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
set params = %*:"=""
echo UAC.ShellExecute "cmd.exe", "/c %~s0 %params%", "", "runas", 1 >> "%temp%\getadmin.vbs"

del "%temp%\getadmin.vbs"
exit /B

pushd "%CD%"
CD /D "%~dp0"
netsh wlan set hostednetwork mode=allow ssid=pau key=12345678
netsh wlan start hostednetwork

Now, when you’ll double click the bat file you will be asked for administrator privilegies.
