massgravel/Microsoft-Activation-Scripts ? reverse-engineered prompt

I need to create a script that can activate different versions of Microsoft Windows and Office. The goal is to make it super simple for someone who's not very technical.

The main way to use it should be with a single command that I can paste into a PowerShell window. This command should fetch the script from a URL and run it, which then opens up a simple text-based menu. From that menu, the user can select what they want to do—like activate Windows 10, Windows 11, or their Office installation.

It's also important to have a backup method. So, please also provide a direct download link for the script as a .cmd file, just in case an ISP or firewall blocks the PowerShell command. The script should be self-contained and easy to run.
