Notepad2 for Windows 7

I have been using Notepad2 for a long time as my default notepad. I just updated one of my machines to Windows 7 64 bit and I needed to set notepad2 up. The good news is that a 64 bit version is available but the bad news is that installation is not the same as vista for making it the default. Here is a batch script I found to get it to work.

@echo off
TITLE Notepad2 Install Script for Complete Windows Vista and 7 Notepad Replacement
echo.
