Как можно создать cmd файл, где можно было изменить страница по умолчанию во всех браузерах? »

Это мягко говоря не реально...

А как тогда сайты ссылку создают на свой сайт, типа Яндех, Маил... ?..

[Iska]

adm1nb3k, они делают сие:
* скриптом;
* изнутри браузера.

Скриптом (а не пакетным файлом), сделать сие для основных браузеров реально.

Iska, а как тогда сделать скрипт? На каком языке?
