Windows Notepad is dated (back to Windows 1.0 in 1985); and there are a number of great freeware/open source alternatives. After reviewing several, I’ve selected Notepad++ as my new notepad of choice.
Notepad++ can be downloaded from http://notepad-plus.sourceforge.net/uk/site.htm
Two other very capable contenders are
- ConTEXT (my old favorite) from http://www.contexteditor.org/
- Programmer’s Notepad from http://www.pnotepad.org/
