Notepad is the default editor when you right-click a batch file in Explorer. I
prefer using UltraEdit-32. To change the default from NotePad to the editor of
your choice:
Hive: HKEY_CLASSES_ROOT
Key:
batfile\shell\edit\command
Name: Default
Type: REG_EXPAND_SZ
Value: %SystemRoot%\System32\NOTEPAD.EXE %1
default
Value: C:\Program
Files\ULTRAEDT\UEDIT32.EXe %1 my choice
For Windows 2000, its No Name
instead of Default.
