    # Remove Duplicate Entries from PATH Environmental Variables

    This PowerShell script will check the system PATH variable and the user PATH variable for duplicates and then remove any duplicates found.

    The script is **NOT** lazy - it *actually* checks each environmental variable **separately**, NOT simply `$ENV:PATH`.

    Enjoy! 😊️️❤
