Sample batch to run itself elevated

get-admin.bat

@echo off

echo Checking for permissions
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"

echo Permission check result: %errorlevel%

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"
echo UAC.ShellExecute "%~s0", "", "", "runas", 1 >> "%temp%\getadmin.vbs"

echo Running created temporary "%temp%\getadmin.vbs"
timeout /T 5
"%temp%\getadmin.vbs"
exit /B

:gotAdmin
if exist "%temp%\getadmin.vbs" ( del "%temp%\getadmin.vbs" )
pushd "%CD%"
CD /D "%~dp0" 

echo Batch was successfully started with admin privileges
echo .
cmd

Great job! Is it possible to make this run as the SYSTEM user instead?

Sure, it's possible. But much more complicated.
You have to run it elevated first, and after that start the script via task scheduler under system account.
Too much work I think.

In ConEmu you can do that easy BTW

Not working for me. It keeps looping and restarts after 5 sec are over been doing that now for 15 mins ))))): help

@Maximus5 Don't remember exactly why I asked you that. 😅 Maybe I needed to change some stubborn file permissions or something, and I ended up settling for nSudo. I know it's late, but I appreciate YOUR quick response. 🙏🏻

@MiggieNRG Maybe try turning the User Account Control notifications off, and see if it'll make a difference (just for debugging purposes, since I don't see why it wouldn't work otherwise.) I use the script every time I feel too lazy to right-click a file, and click "Run as administrator", and so far, it has never failed me. Hope this helps, Miguel.

General debugging tips:
Remove "echo off"
Add pause command in some places
Run and see the output

Another variant would be:

@echo off

echo Checking for permissions
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"

echo Permission check result: %errorlevel%

REM --> If error flag set, we do not have admin.
if '%errorlevel%' NEQ '0' (
echo Requesting administrative privileges...
goto UACPrompt
) else ( goto gotAdmin )

:UACPrompt
if exist "%SYSTEMROOT%\System32\Cscript.exe" ( goto VBS )
goto PS

:VBS
echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
echo UAC.ShellExecute "%~s0", "", "", "runas", 1 >> "%temp%\getadmin.vbs"

echo Running created temporary "%temp%\getadmin.vbs"
timeout /T 5
"%temp%\getadmin.vbs"
exit /B

:PS
REM timeout /T 5
powershell -Command "Start-Process -Verb RunAs -FilePath '%0' -ArgumentList 'am_admin'"
exit /b

:gotAdmin
if exist "%temp%\getadmin.vbs" ( del "%temp%\getadmin.vbs" )
pushd "%CD%"
CD /D "%~dp0"

echo Batch was successfully started with admin privileges
echo .
cmd

This primarily uses the execution in vbs. If removed from newer Windows versions, execution in powershell is used

It becomes more modern with the following code

@echo off

>nul 2>&1 fsutil dirty query %systemdrive% && (goto gotAdmin) || (goto UACPrompt)
:UACPrompt
if exist "%SYSTEMROOT%\System32\Cscript.exe" (
    echo Set UAC = CreateObject^("Shell.Application"^) : UAC.ShellExecute "%~s0", "", "", "runas", 1 > "%temp%\getadmin.vbs" 
    "%temp%\getadmin.vbs"
    exit /b
) else (
    powershell -Command "Start-Process -Verb RunAs -FilePath '%0' -ArgumentList 'am_admin'"
    exit /b
)
:gotAdmin
if exist "%temp%\getadmin.vbs" del "%temp%\getadmin.vbs"
pushd "%CD%" && CD /D "%~dp0"
cls
cmd
