  1. _RunWithReducedPrivileges An odd thing about Vista+ O/S's is that, once you run a process in elevated privileges mode, you can't run other processes in lower-privileged modes. Why, you ask, would that be important? Sometimes you want - or need - to limit the privileges of a process: A very common scenario for me is drag-and-drop. Windows' Explorer does NOT allow this to occur between lower privileged processes (like Explorer itself!) and other processes. This is very frustrating for users in programs that take advantage of that. There's also some problems using certain SendMessage commands from other unelevated processes.Setting the state or properties of windows that have an elevated privilege may not work either from other unelevated processes..An install or setup program that needs to launch the installed program will more often than not want to run that program on a lower privilege level (for some of the reasons mentioned above)So, after some looking around I found a way of running processes under a lower privilege mode.Check Elmue's comment 'Here the cleaned and bugfixed code' on this CodeProject page to see where my code was ported from:'Creating a process with Medium Integration Level from the process with High Integration Level in Vista' The usage is straightforward for this one: use it like Run/RunWait, but with the command-line as the 2nd parameter. [i.e. _RunWithReducedPrivileges(@ComSpec,' /k title Non-Admin prompt') ] Anyway, hope this helps someone out!

  2. I previously ran SciTE and Autoit from a Windows XP machine and therefore didn't have any UAC or privileges issues to deal with. Now I'm running Win7 64 bit and noticed that when opening a .au3 file I don't get any prompt choice to run as admin. It simply opens the file I requested. When I hit F5 or click on "Go" to run the application SciTE is unable to hook into the app and get Console output when run like this. I can, however, go through the trouble of opening SciTE independently as administrator before opening the source code .au3 files and when I hit f5 or "Go" like this I am again able to get ConsoleWrite output as well as get runtime errors. My question: Is it possible to modify the SciTE editor so that it prompts to run as administrator when attempting to open a .au3 file rather than right clicking on SciTE and manually selecting to run as administrator and then opening the .au3 file? I'm trying to achieve a shortcut and save time while removing one more annoyance that is UAC Win7 powered. Many thanks!
  3. _ShellExecuteWithReducedPrivileges An odd thing about Vista+ O/S's is that, once you run a process in elevated privileges mode, you can't run other processes in lower-privileged modes. Why, you ask, would that be important? Sometimes you want - or need - to limit the privileges of a process: A very common scenario for me is drag-and-drop. Windows' Explorer does NOT allow this to occur between lower privileged processes (like Explorer itself!) and other processes. This is very frustrating for users in programs that take advantage of that. There's also some problems using certain SendMessage commands from other unelevated processes.Setting the state or properties of windows that have an elevated privilege may not work either from other unelevated processes.An install or setup program that needs to launch the installed program will more often than not want to run that program on a lower privilege level (for some of the reasons mentioned above)So, after some looking around I found two ways of running processes under a lower privilege mode. One is using CreateProcessWithTokenW (see ), and the other is using COM objects - specifically Windows Explorer's SHELL object to ShellExecute a command/program. This can be used just like AutoIt's built-in ShellExecute() function, but of course the program that runs will be at a reduced IL (integrity level). The code is based on Brandon @ BrandonLive's article here: 'Getting the shell to run an application for you - Part 2:How | BrandonLive' The usage is straightforward for this one: use it like ShellExecute. The $bWait parameter is only there in case ShellExecuteWait() will be called for either non-elevated processes or pre-Vista O/S's. Example: _ShellExecuteWithReducedPrivileges(@ComSpec,' /k title Non-Elevated prompt (via Shell.ShellExecute)') Anyway, hope this helps someone out!
