    I have written a batch script which takes admin privileges and then Kill a certain process if exist and rerun it else just run it.

    Code:
    @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 )

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

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

:gotAdmin
    pushd "%CD%"
    CD /D "%~dp0"
:--------------------------------------
tasklist /fi "imagename eq SynTPEnh.exe" |find ":" > nul
if errorlevel 1 taskkill /f /im "SynTPEnh.exe"&start "" "c:\Program Files\Synaptics\SynTP\SynTPEnh.exe"
if errorlevel 0 start "" "c:\Program Files\Synaptics\SynTP\SynTPEnh.exe"
    I have scheduled it as task and the trigger is whenever someone unlock the workstation.

    Everything runs smoothly but the problem is there is command prompt popup when the script runs for a few second.

    For elimination of that i have created a Wscript

    Code:
    Set oShell = CreateObject ("Wscript.Shell") 
Dim strArgs
strArgs = "cmd /c touchpad.bat"
oShell.Run strArgs, 0, false
    When i trigger this script from task scheduler it seems not to run. But doesnt report any error as well.

    My main aim is to run my batch script without cmd prompt on run.

    Regards

    Changes:

    - Use .vbs script to check for admin privileges then run batch file in silent mode
    - Removed 'getadmin' code from batch since it's no longer needed; VBScript already takes care of this
    - Added 2 second delay before attempt to restart process

    Usage:

    - Trigger .vbs script from Task Scheduler

    ------------

    touchpad.bat
    Code:
    @echo off
cd /d "%~dp0"
:Begin
tasklist /fi "imagename eq SynTPEnh.exe" |find ":"
if %errorlevel% == 0 (
    start "" "%ProgramFiles%\Synaptics\SynTP\SynTPEnh.exe"
    EXIT
) else (
    taskkill /f /im "SynTPEnh.exe"
)
ping -n 3 127.0.0.1 >nul
goto Begin
    ------------

    touchpad.vbs
    Code:
    Set objWsh = WScript.CreateObject("WScript.Shell")
Set objShellApp = CreateObject("Shell.Application")

If WScript.Arguments.length = 0 Then 
    objShellApp.ShellExecute "wscript.exe", """" & WScript.ScriptFullName & """" & " RunAsAdministrator", , "runas", 1 
    WScript.Quit
Else
End If

objWsh.Run "" & """[drive:][path]filename""" & "", 0
    Notes:

    Modify the last line accordingly; specify the full path to batch file - eg. D:\scripts\touchpad.bat
