How to add administrator privileges to AutoHotkey script?

Try adding this to the auto-execute section (top of the script):

; If the script is not elevated, relaunch as administrator and kill current instance:

full_command_line := DllCall("GetCommandLine", "str")

if not (A_IsAdmin or RegExMatch(full_command_line, " /restart(?!\S)"))
{
    try ; leads to having the script re-launching itself as administrator
    {
        if A_IsCompiled
            Run *RunAs "%A_ScriptFullPath%" /restart
        else
            Run *RunAs "%A_AhkPath%" /restart "%A_ScriptFullPath%"
    }
    ExitApp
}

and recompile the script.

For more details read https://autohotkey.com/docs/commands/Run.htm#RunAs.

Here's a much simpler code for this purpose:

if not A_IsAdmin
Run *RunAs "%A_ScriptFullPath%"

It will run the script as Admin if it's not already running as Admin.

If you don't have #SingleInstance Force on top of your script, it will ask that if you want to replace the running script (not admin) with admin. So to prevent that, add the mentioned line on top of your script.

Also have a look at this code (it didn't work for me):

if !A_IsAdmin
    Run, % "*RunAs " (A_IsCompiled ? "" : A_AhkPath " ") Chr(34) A_ScriptFullPath Chr(34)

Chr(34) returns character "
