How to request Administrator access inside a batch file

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.

    <YOUR BATCH SCRIPT HERE>

Here's what I've been using:

@echo off
if not "%1"=="am_admin" (
    powershell -Command "Start-Process -Verb RunAs -FilePath '%0' -ArgumentList 'am_admin'"
    exit /b
)

echo main code here
pause

Notes:

The -Verb RunAs flag of Start-Process is what enables the administrative elevation.

Only tested on windows 7 and 10, you might have to mess around with the quoting

Doesn't support passing along arguments for now, but you might be able to add more stuff to -ArgumentList. Note that -ArgumentList accepts either a single string or a string array.

---

Here is my code! It looks big but it is mostly comment lines (the lines starting with ::).

Features:

Full argument forwarding

Does not change working folder

Error handling

Accepts paths with parenthesis (except for %TEMP% folder)

Supports UNC paths

Mapped folder check (Warn´s you if admin can´t access mapped drive)

Can be used as an external library (check my post at this topic: https://stackoverflow.com/a/30417025/4932683)

Can be called when/if needed anywhere in your code

Just attach this to the end of your batch file, or save it as a library (check above)

Example on how to use it

:EXAMPLE

 :: Run this script with elevation
 call :RequestAdminElevation "%~dpfs0" %* || goto:eof

  echo/I now have Admin rights!
  echo/
  echo/Arguments using %%args%%:    %args%
  echo/Arguments using %%*: %*
  echo/%%1= %~1
  echo/%%2= %~2
  echo/%%3= %~3

  echo/
  echo/Current Directory: %CD%
  echo/
  echo/This file: %0
  echo/

pause &goto:eof

[here you paste the RequestAdminElevation function code]

---

Another approach is to

create a shortcut locally and set it to call for Admin permission (Properties, Advanced, Run as Admin)

and then

send your users the shortcut (or a link to the shortcut rather than one to the batch file itself).

---

Ben Gripka's solution causes infinite loops. His batch works like this (pseudo code):

IF "no admin privileges?"
    "write a VBS that calls this batch with admin privileges"
ELSE
    "execute actual commands that require admin privileges"

As you can see, this causes an infinite loop, if the VBS fails requesting admin privileges.

However, the infinite loop can occur, although admin priviliges have been requested successfully.

The check in Ben Gripka's batch file is just error-prone. I played around with the batch and observed that admin privileges are available although the check failed. Interestingly, the check worked as expected, if I started the batch file from windows explorer, but it didn't when I started it from my IDE.

So I suggest to use two separate batch files. The first generates the VBS that calls the second batch file:

@echo off

echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
set params = %*:"=""
echo UAC.ShellExecute "cmd.exe", "/c ""%~dp0\my_commands.bat"" %params%", "", "runas", 1 >> "%temp%\getadmin.vbs"

"%temp%\getadmin.vbs"
del "%temp%\getadmin.vbs"

The second, named "my_commands.bat" and located in the same directory as the first contains your actual commands:

pushd "%CD%"
CD /D "%~dp0"
REM Your commands which require admin privileges here

This causes no infinite loops and also removes the error-prone admin privilege check.

Another PowerShell Solution...

This is not about running a batch script as admin per, but rather how to elevate another program from batch...

I have a batch file "wrapper" for an exe. They have the same "root file name", but alternate extensions. I am able to launch the exe as admin, and set the working directory to the one containing the script, with the following one line powershell invocation:

@powershell "Start-Process -FilePath '%~n0.exe' -WorkingDirectory '%~dp0' -Verb RunAs"

More info

There are a whole slew of additional Start-Process options as well that you can apply! Check out: https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.management/start-process?view=powershell-6

Note that I use the @ prefix. That's equivalent to @echo off for the one line. I use %~n0 here to get the "root name" of the batch script, then I concatenate the .exe to point it the adjancent binary. The use of %~dp0 provides the full path to the directory which the batch resides. And, of course, the -Verb RunAs parameter provides the elevation.

---

I know this is not a solution for OP, but since I'm sure there are many other use cases here, I thought I would share.

I've had problems with all the code examples in these answers but then I found : http://www.robotronic.de/runasspcEn.html

It not only allows you to run as admin, it checks the file to make sure it has not been tampered with and stores the needed information securely. I'll admit it's not the most obvious tool to figure out how to use but for those of us writing code it should be simple enough.

---

@echo off 
Net session >nul 2>&1 || (PowerShell start -verb runas '%~0' &exit /b)
Echo Administrative privileges have been got. & pause

The above works on my Windows 10 Version 1903

---

@echo off and title can come before this code:

net session>nul 2>&1
if %errorlevel%==0 goto main
echo CreateObject("Shell.Application").ShellExecute "%~f0", "", "", "runas">"%temp%/elevate.vbs"
"%temp%/elevate.vbs"
del "%temp%/elevate.vbs"
exit

:main
    <code goes here>
exit

A lot of the other answers are overkill if you don't need to worry about the following:

Parameters

Working Directory (cd %~dp0 will change to the directory containing the batch file)

---

There's also the FSUTIL query from this post which is also linked at ss64.com that has the following code:

@Echo Off
Setlocal
:: First check if we are running As Admin/Elevated
FSUTIL dirty query %SystemDrive% >nul
if %errorlevel% EQU 0 goto START

::Create and run a temporary VBScript to elevate this batch file
   Set _batchFile=%~f0
   Set _Args=%*
   :: double up any quotes
   Set _batchFile=""%_batchFile:"=%""
   Set _Args=%_Args:"=""%

   Echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\~ElevateMe.vbs"
   Echo UAC.ShellExecute "cmd", "/c ""%_batchFile% %_Args%""", "", "runas", 1 >> "%temp%\~ElevateMe.vbs"

   cscript "%temp%\~ElevateMe.vbs" 
   Exit /B

:START
:: set the current directory to the batch file location
cd /d %~dp0
:: Place the code which requires Admin/elevation below
Echo We are now running as admin [%1] [%2]
pause

As long as FSUTIL is around, it's a reliable alternative.

Since I have troubles with this script popping up a new command prompt with itself run again, in infinite loop (using Win 7 Pro), I suggest you try another approach :How can I auto-elevate my batch file, so that it requests from UAC administrator rights if required?

Be careful, you have to add this at the end of script, as stated in an edit, so that you are back to script directory after privileges were elevated : cd /d %~dp0

Based on post by toster-cx and other interesting posts on this page, I got insight on how to configure and solve my problem. I had similar issue where I wished that Disk Cleanup utility runs every week twice on Monday and Thursday during lunch hours (say 2 pm). However, this required elevated rights.

Sharing batch file which might help other beginners like me -

@echo off
echo  Welcome to scheduling 'PC Maintenance Activity'
ping localhost -n 3 >nul
echo -- Step - 1 of 3 : Please give 'Admin' rights on next screen
ping localhost -n 5 >nul
if not "%1"=="am_admin" (powershell start -verb runas '%0' am_admin & exit)
cls
echo -- Step - 2 of 3 : In next screen, select temp areas for cleaning 
during routine scheduled activity
ping localhost -n 3 >nul
C:\Windows\System32\cleanmgr.exe /sageset:112
cls
echo    Now scheduling maintenance activity...
SchTasks /Create /SC WEEKLY /D MON,THU /TN PC_Cleanup /TR 
"C:\Windows\System32\cleanmgr.exe "/sagerun:112 /ST 14:00

cls

echo                         -- Thanks for your co-operation --
echo                    -- Maintenance activity is scheduled for --
echo                       -- Every Monday and Thursday at 2 pm --

ping localhost -n 10 >nul

Thanks a lot for this forum and Rems POST here [https://www.petri.com/forums/forum/windows-scripting/general-scripting/32313-schtasks-exe-need-to-pass-parameters-to-script][1]

His post helped for configuring optional argument while scheduling the task.

Use mshta to prompt for admin rights:

@echo off
net session >nul 2>&1 && goto :admintasks
MSHTA "javascript: var shell = new ActiveXObject('shell.application'); shell.ShellExecute('%~nx0', '', '', 'runas', 1);close();"
exit /b
:admintasks
rem ADMIN TASKS HERE

Or, using powershell:

powershell -c Start-Process "%~nx0" -Verb runas

---

You can't request admin rights from a batch file, but you could write a windows scripting host script in %temp% and run that (and that in turn executes your batch as admin) You want to call the ShellExecute method in the Shell.Application object with "runas" as the verb

---

I used multiple examples to patch this working one liner together.

This will open your batch script as an ADMIN + Maximized Window

Just add one of the following codes to the top of your batch script. Both ways work, just different ways to code it.

I believe the first example responds the quickest due to /d switch disabling my doskey commands that I have enabled..

EXAMPLE ONE

@ECHO OFF
IF NOT "%1"=="MAX" (powershell -WindowStyle Hidden -NoProfile -Command {Start-Process CMD -ArgumentList '/D,/C' -Verb RunAs} & START /MAX CMD /D /C %0 MAX & EXIT /B)
:--------------------------------------------------------------------------------------------------------------------------------------------------------------------

:: Your original batch code here:

:--------------------------------------------------------------------------------------------------------------------------------------------------------------------

EXAMPLE TWO

@ECHO OFF
IF NOT "%1"=="MAX" (powershell -WindowStyle Hidden -NoProfile -Command "Start-Process CMD -ArgumentList '/C' -Verb RunAs" & START /MAX CMD /C "%0" MAX & EXIT /B)
:--------------------------------------------------------------------------------------------------------------------------------------------------------------------

:: Your original batch code here:

:--------------------------------------------------------------------------------------------------------------------------------------------------------------------

See below for recommendations when using your original batch code

Place the original batch code in it's entirety

Just because the first line of code at the very top has @ECHO OFF doesn't mean you should not include it again if your original script has it as well.

This ensures that when the script get's restarted in a new window now running in admin mode that you don't lose your intended script parameters/attributes... Such as the current working directory, your local variables, and so on

You could beginning with the following commands to avoid some of these issues

:: Make sure to use @ECHO OFF if your original code had it
@ECHO OFF
:: Avoid clashing with other active windows variables with SETLOCAL
SETLOCAL
:: Nice color to work with using 0A
COLOR 0A
:: Give your script a name
TITLE NAME IT!

:: Ensure your working directory is set where you want it to be
:: the following code sets the working directory to the script directory folder
PUSHD "%~dp0"

THE REST OF YOUR SCRIPT HERE...

:: Signal the script is finished in the title bar
ECHO.
TITLE Done! NAME IT!
PAUSE
EXIT

---

use the runas command. But, I don't think you can email a .bat file easily.
