RTK_ImpExp.ps1

<#
.SYNOPSIS
Backup and restore your Realtek Audio settings.

.DESCRIPTION
v1.0.6
You get a "Full" and "EQ" reg file on backup. It is encouraged to only restore the "EQ" version.
All consequences are unknown if you import "Full".
You cannot double click the either reg file without loading the hive! It will not work.

.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/rtk

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