.DESCRIPTION

.NOTES
While this script is clearly safe, if you download a file Windows may block it.
You will need to unblock it if that's the case.
Additionally, PowerShell blocks running scripts for safety. Run the command:
	set-executionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
	set-executionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
You can revert this change with the command:
	set-executionPolicy -ExecutionPolicy Default -Scope LocalMachine
	set-executionPolicy -ExecutionPolicy Default -Scope CurrentUser

You can read more about how to use this script here: https://go.icedterminal.me/ctxt

.EXAMPLE
Right click this file and click "Run with PowerShell 7"
