Windows comes with Notepad and Wordpad. These are fine for changing a few things in EU3 text files. But if you are doing a lot of editing, you should look at some more advanced tools. They'll let you do complex search and replace (including across the ends of lines, plus including tab characters and searching for complex varieties of strings), and many other things that the standard Windows text editors never dreamt of:
- UltraEdit by IDM Computer Solutions, Inc.
- Crimson Editor a full-featured open source professional text editor.
- Emacs - The extensible, customizable, self-documenting real-time display editor. Download (look for the "bin" or "fullbin"-files) - FAQ for Windows version
- DNOTE - Duncans Notepad - (Shareware) Allows editing of multiple text files simultaneously. Like the province files or the country and adviser files
- Scintilla and Scite - another multiple text file editor with syntax formating, and bracket checking.
- Notepad++ - a perennial favorite
- gVim - this is one of the most complicated editors, but with complexity comes power!
- TextPad - Another text editor that's way better than NotePad
