Spawning a process with reduced privileges

[WildByDesign]

This topic has been around before but not much within the last decade. There was an older script _RunWithReducedPrivileges.au3 by @Ascend4nt but it no longer works. It's possible that it was like many scripts that worked on x86 but don't work now that everything is x64.

Goal: I have a main script that runs elevated. It also spawns the GUI script which, due to the main script being elevated. runs elevated as well. I would like to spawn the GUI script with reduced privileges because it really just doesn't need to run elevated.

Is there a function to do this that works on 64-bit machines as well?

Thank you.

By the way, I spent a few hours last night searching the forum and reading some threads on this topic. I also spent some time this morning as well. I have to be honest, the forum search functionality misses so much great stuff no matter how crafty your search words are. I find that searching the forum from Google provides significantly better results and finds stuff that I couldn't find with the forum's own search. Without a doubt, this forum is a gold mine of information.
