Doing things Microsoft should have done to begin with

Microsoft makes you go through a list of known applications when you click on an unknown file. It's time consuming and an aggravation.  If you know it's some sort of text-based file then a better method is to quickly open it with Notepad. But you don't have that option in Windows Explorer unless you do this Open with Notepad hack.

This will allow you to use Notepad to open a file by simply right clicking on the icon. Also the Notepad will be used to open files by default if no association already exists.
