The How-To Geek posted this easy Windows registry hack that will add an “Open with Notepad” option to the right click menu for all files:

Open regedit.exe through the start menu search or run box, and then browse down to the following key:


Right-click on “shell” and choose to create a new key, calling it “Open with Notepad”. Create a new key below that one called “command”. Double-click on the (Default) value in the right-hand pane and enter in the following:

notepad.exe %1

The other option is to drag a shortcut to the Notepad application to the “Documents and SettingsUsernameSendTo” folder. I dig how the registry hack adds it right to the top of the context menu, though. More often than not, I want to open a file with Notepad, regardless of its default file association, so it saves some time having this at the top of the list.
