I’m a big fan of right-click context menu choices. I use Enqueue/Play In Winamp, Send To -> Compressed File, and Copy This Path almost every day.
This little registry hack adds an Open With Notepad option to your right click context menu. As Zeus attests, you don’t know blankity-blank about computers unless you open notepad at least five times a day.
To do this hack, copy and past the following into Notepad. Next you need to save it as a .reg file and then import it into the windows registry by clicking on it.
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT*shellOpen with Notepad]
[HKEY_CLASSES_ROOT*shellOpen with Notepadcommand]
I picked this up from Tweak Vista.
Update: There is a way to do this using the Send To sub-menu that doesn’t require a registry edit, see comments below.
