[SCCM] Easily find GUID to create an extension.ps1

##################################################################################################################
# Description:
#     This script helps Extensions creators to quickly create a new extension that can add some contextual menu
#     to their desired location (Collection, Software Update group, whatever the Administrator UI Allows...)
#     When creating an extension in SCCM, you need to define with which component of the UI it will interact.
#     this guid is a bit difficult to find (you need to search through XML files).
#     For this purpose, this script will create an extension action per UI component so that everywhere you
#     can right click in the SCCM Administrator User Interface, a contextual menu will appear with it's GUID displayed
#     clicking on this GUID will copy it to the clibpard.
##################################################################################################################
# Warning:
#     This script will create extensions in the folder ($$env:SMS_ADMIN_UI_PATH\..\..\XmlStorage\Extensions\Actions)
#     /!\ Warning 1: TAKE TIME TO BACKUP THE EXTENSION FOLDER ^.
#         On a default installation, THE FOLDER TO BACKUP IS:
#         C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\XmlStorage\Extensions
#
#     /!\ Warning 2: Don't run this on production if you are unsure of what you are doing.
#         On my test machine, running this script will result in the creation of 6000 files which will slow down 
#         Admin UI loading time.
#         Even if it's not specifically dangerous, it's never good to play on production environments.
##################################################################################################################
# Usage :
#     - Run this script once AS ADMINISTRATOR
#     - Close and start again the SCCM Admin Console
#     - Right click everywhere in the UI to reveal the associated GUID
#     - Create your extension's actions with this GUID

#     Credits goes to this great article: https://www.ephingadmin.com/create-your-own-right-click-tools/
#     Modifications from the original code:
#     - Modified the way clipboard is set
#     - Force the script to require Admin right to have appropriate right for folder / file creation
