I have created a batch file for starting a service using sc.exe. But it asks for admin privilege while running. Is there is any code that can be used in batch file to elevate cmd to admin level?

Press Windows Key + X and click Command Prompt (Admin). Click yes if the user control center ask for permission

You can do this: 

@echo off
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"
if %errorlevel% NEQ 0 (GOTO askAdmin)
GOTO gotAdmin


:askAdmin
::batch is being ran as normal user
echo I'm not an admin yet
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"
if '%errorlevel%' NEQ '0' (
echo Requesting administrative privileges...
goto UACPrompt
) else ( goto gotAdmin )
:UACPrompt
echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
echo UAC.ShellExecute "%~s0", "", "", "runas", 1 >> "%temp%\getadmin.vbs"
"%temp%\getadmin.vbs"
exit /B


:gotAdmin
if exist "%temp%\getadmin.vbs" ( del "%temp%\getadmin.vbs" )
pushd "%CD%"
CD /D "%~dp0"
::batch is being ran as admin
echo Now I'm an admin!
pause

  • I used this but it is asking permission in between execution. Is it possible to avoid this situation..i.e, run cmd as admin without asking permission, – shijin Jan 27 '16 at 08:21
  • @shijin you can run it as admin from the start by right clicking on it or using the shortcut mentioned in the other answer, but this is the only way to do it in the program itself – Dennis van Gils Jan 27 '16 at 08:24
  • Is there is any way to get admin privilege from code itself? Without clicking run as admin? – shijin Jan 27 '16 at 08:35
  • @shijin That is what the code I provided does. However, it would be weird if a program could give itself admin priviliges without needing to ask for them. That would be a huge security threat, imagine a virus giving itself admin rights without needing confirmation from you. – Dennis van Gils Jan 27 '16 at 12:26
  • my project is a forensic project. the project is to acquire the ram dump directly while plugging in a usb drive. while dumping there should be minimal user interactions. – shijin Jan 29 '16 at 07:18
