Agregar "Abrir con Notepad++" para el menú contextual del Explorador de Windows

Abrimos el cmd ( "Windows + R" y escribimos "cmd" ) con permiso de administrador  y copamos el siguiente código. Pulsamos intro y, "Listo".

Nota: Revisa el directorio (notepadPath) donde tienes instalado el programa notepad++. En mi caso particular, notepad se encuentra en la siguiente ruta C:\Program Files (x86)\npp.7.2\

@echo off SET notepadPath=C:\Program Files (x86)\npp.7.2\notepad++.exe    rem add it for all file types @reg add "HKEY_CLASSES_ROOT\*\shell\Open with notepad++"         /t REG_SZ /v "" /d "Open with notepad++"   /f @reg add "HKEY_CLASSES_ROOT\*\shell\Open with notepad++"         /t REG_EXPAND_SZ /v "Icon" /d "%notepadPath%,0" /f @reg add "HKEY_CLASSES_ROOT\*\shell\Open with notepad++\command" /t REG_SZ /v "" /d "%notepadPath% %1" /f   rem add it for folders @reg add "HKEY_CLASSES_ROOT\Folder\shell\Open with notepad++" /t REG_SZ /v "" /d "Open with notepad++" /f @reg add "HKEY_CLASSES_ROOT\Folder\shell\Open with notepad++" /t REG_EXPAND_SZ /v "Icon" /d "%notepadPath%,0" /f @reg add "HKEY_CLASSES_ROOT\Folder\shell\Open with notepad++\command" /t REG_SZ /v "" /d "%notepadPath% %1" /f pause

A modo de ejemplo vamos a hacerlo lo mismo para Brackets, para ver que es aplicable para todos los programas.
