## Fun fact, most of this code is generated entirely using GPT-3.5  ## CHATGPT PROMPT 1 ## Explain to me how to parse a conf file in PowerShell.  ## AI EXPLAINS HOW... this is important as it invokes reflective thinking. ## Having AI explain things to us first before asking  ## your question, significantly improves the quality of the response.   ### PROMPT 2 ### Okay, using this conf, can you write a powershell script that saves a new value to the global_prep_cmd?  ### AI Generates valid code for saving to conf file  ## Prompt 3 ### I think I have found a mistake, can you double check your work?  ## Again, this is important for reflective thinking, having the AI ## check its work is important, as it may improve quality.   ## Response: Did not find any errors.  ## Prompt 4: I tried this and unfortunately my config file requires admin to save.  ## AI Responses solutions  ## Like before, I already knew the solution but having the AI ## respond with tips, greatly improves the quality of the next prompts  ## Prompt 5 (Final with GPT3.5): Can you make this script self elevate itself. ## Repeat the same prompt principles, and basically 70% of this script is entirely written by Artificial Intelligence. Yay!  ## Refactor Prompt (GPT-4): Please refactor the following code, remove duplication and define better function names, once finished you will also add documentation and comments to each function. param($install) $filePath = $($MyInvocation.MyCommand.Path) $scriptRoot = Split-Path $filePath -Parent $scriptPath = "$scriptRoot\ResolutionMatcher.ps1"   # This script modifies the global_prep_cmd setting in the Sunshine configuration file # to add a command that runs ResolutionMatcher.ps1  # Check if the current user has administrator privileges $isAdmin = [bool]([System.Security.Principal.WindowsIdentity]::GetCurrent().groups -match 'S-1-5-32-544')  # If the current user is not an administrator, re-launch the script with elevated privileges if (-not $isAdmin) {     Start-Process powershell.exe  -Verb RunAs -ArgumentList "-ExecutionPolicy Bypass -NoExit -File `"$filePath`" $install"     exit }  function Test-AndRequest-SunshineConfig {     param(         [string]$InitialPath     )      # Check if the initial path exists     if (Test-Path $InitialPath) {         Write-Host "File found at: $InitialPath"         return $InitialPath     }     else {         # Show error message dialog         [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") | Out-Null         [System.Windows.Forms.MessageBox]::Show("Sunshine configuration could not be found.
