How to request Administrator access inside a batch file

Solution 1:

This script does the trick! Just paste it into the top of your bat file. If you want to review the output of your script, add a "pause" command at the bottom of your batch file.

UPDATE: This script is now slightly edited to support command line arguments and a 64 bit OS.

@echo off

:: BatchGotAdmin
:-------------------------------------
REM  --> Check for permissions
    IF "%PROCESSOR_ARCHITECTURE%" EQU "amd64" (
>nul 2>&1 "%SYSTEMROOT%\SysWOW64\cacls.exe" "%SYSTEMROOT%\SysWOW64\config\system"
) ELSE (
>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"

Solution 2:

Here's a one-liner I've been using:

@echo off
if not "%1"=="am_admin" (powershell start -verb runas '%0' am_admin & exit /b)

echo main code here
pause

Notes:

• Only tested on windows 7 and 10, you might have to mess around with the quoting
• Doesn't support passing along arguments for now
