What would you like to do?
Lean and Mean runas TrustedInstaller / System compact snippet to easily integrate in your batch scripts
@echo off & title AveYo`s :runasTI snippet usage showcase (final)
:: First handle command line parameters (for example via Send to) to run as TrustedInstaller AllPrivileges
if /i "%~dp0" equ "%APPDATA%\Microsoft\Windows\SendTo\" call :runasTI 1 %* &exit/b
echo Fully portable, compact, plain-text runas TrustedInstaller or SYSTEM snippet v20191010
echo ========================================================================================
echo - now also supports short common programs names such as cmd, regedit, powershell..
echo - now sets console buffer so that the scrollbars are visible!
echo - should work even on naked Windows 7 with powershell 2.0, both x64 and x86
echo - snippet is minified for size but still very readeable
echo - just copy-paste the 18 lines in your own batch scripts and call the snippet as needed!
echo - can also be used from the right-click - Send to menu (entry appears after 1st run)

:: If this script is already elevated to SYSTEM prevent loop and just print a message
