Sorry, I didn’t mean to sound harsh. I know you were just trying to be helpful. I see no problem with leaving the link to the other thread.
To use the tool, you will need to open PowerShell, navigate to where you have the script saved, and then execute it from there. If you follow the instructions in the Github page, it should be able to guide you through the process for using this tool. If you have any problems with it, please describe the issue here or there and I will try to clarify what needs to be done.
