.SYNOPSIS
    Identifies the "ultimate owner" of a given process by tracing its parent process hierarchy and analyzing its command-line arguments.

.DESCRIPTION
    This script finds all instances of a specified process name and attempts to determine the application that spawned it.
    It does this by:
    
    1. Retrieving all matching processes from the system.
    2. Checking if the process's command-line arguments include `--webview-exe-name=`, which often reveals the true owner.

# .\remove_from_path.ps1 -DirectoryToRemove "C:\Path\To\Directory" -Target Machine
# This will remove C:\Path\To\Directory from the system PATH.

Updated 2023/05/15 by Mark Castle (and ChatGPT :P) to add excluded paths and to also 
give the option of opening files in the current editor, plus some minor tweaks
to keep re-sharper happy.
