@echo off& title RunAsTI - lean and mean snippet by AveYo, 2018-2022
goto :nfo
    [FEATURES]
    - innovative HKCU load, no need for reg load / unload ping-pong; programs get the user profile
    - sets ownership privileges, high priority, and explorer support; get System if TI unavailable
    - accepts special characters in paths for which default run as administrator fails
    - adds Send to - RunAsTI right-click menu entry to launch files and folders as TI via explorer
    [USAGE]
    - First copy-paste RunAsTI snippet after .bat script content
    - Then call it anywhere to launch programs with arguments as TI
      call :RunAsTI regedit
      call :RunAsTI powershell -noprofile -nologo -noexit -c [environment]::Commandline
      call :RunAsTI cmd /k "whoami /all & color e0"
      call :RunAsTI "C:\System Volume Information"
    - Or just relaunch the script once if not already running as TI:
      whoami /user | findstr /i /c:S-1-5-18 >nul || ( call :RunAsTI "%~f0" %* & exit /b )
