Батник-патчер, убирающий это принудительное предупреждение:

1. Скопируйте код ниже и сохраните в любом текстовом редакторе как, например, DevWarningPatch.bat на рабочем столе

2. Закройте хром вручную, чтобы не потерять незаконченное письмо, например, батник сам завершит оставшиеся спрятанные процессы хрома принудительно.

3. Нажмите правой кнопкой мыши на сохраненном файле и запустите его от имени администратора, чтобы пропатчить все установленные версии хрома (поиск осуществляется посредством реестра или в текущей папке).

Также можно просто перетянуть chrome.dll из папки портабельного хрома на иконку батника.
