To show the password of your WIFI SSID , you must execute this batch file with admin rights :
#echo off & setlocal enabledelayedexpansion
Set "Copyright=by Hackoo 2017"
Title %~n0 %Copyright%
Mode con cols=75 lines=8
cls & color 0A & echo.
echo ***********************************************
echo %~n0 %Copyright%
echo ***********************************************
echo(
if _%1_==_Main_ goto :Main
Set Count=0
Set L=0
:getadmin
echo %~nx0 : self elevating
set vbs=%temp%\getadmin.vbs
(
echo Set UAC = CreateObject^("Shell.Application"^)
echo UAC.ShellExecute "%~s0", "Main %~sdp0 %*", "", "runas", 1
)> "%vbs%"
"%temp%\getadmin.vbs"
del "%temp%\getadmin.vbs"
goto :eof
::*************************************************************************************

Call :init
Call :CountLines
Set "PasswordLog=%~dp0Wifi_Passwords_on_%ComputerName%.txt"

for /f "skip=2 delims=: tokens=2" %%a in ('netsh wlan show profiles') do (
if not "%%a"=="" (
set "ssid=%%a"
set "ssid=!ssid:~1!"
call :Getpassword "!ssid!"
)
)
echo(
echo Done

This works. You can change the TEMPFILE to wherever you want the file to be created.
SET "TEMPFILE=%USERPROFILE%\Desktop\savedpasskey.txt"
netsh wlan show profile name=wifi_name key=clear >"%TEMPFILE%"
TYPE "%TEMPFILE%"

It was not working because the path you specified to save your output text file was not getting recognized. The below code should work properly.
#echo off
netsh wlan show profile name=wifi_name key=clear >%USERPROFILE%\Desktop\savedpasskey.txt
#pause
It's always better to specify fully qualified path for the files. In this case it will be C:\Users\<User_Name>\Desktop\savedpasskey.txt where %USERPROFILE% will been replaced with C:\Users\<User_Name>.
Remove #pause if you don't want the command prompt to stay on screen after command is executed.
