Наконец, и благодаря Noseratio комментарий (+1), я реализовывал Browser Функция управления, так как это не требует прав администратора. Я также открыл ключи в реестре как нестабильные, чтобы не оставлять реестр грязным после возможной деинсталляции.
В ответ связаны Noseratio reffers на C#, я оставляю здесь перевод на C++, если кто-то нуждается в нем с объяснениями того, что каждая функция делает:

LONG nError = RegCreateKeyEx(HKEY_CURRENT_USER, path.c_str(), 0, NULL, REG_OPTION_VOLATILE, KEY_WRITE, NULL, &key, NULL);
if (nError != ERROR_SUCCESS) {
success = false;
} else {
nError = RegSetValueExW(key, appName, 0, REG_DWORD, (const BYTE*) &value, sizeof(value));
if (nError != ERROR_SUCCESS) {

** Первый вопрос **: Вы должны реализовать Управление функциями браузера: http://stackoverflow.com/a/18333982/1768303, ** второй вопрос **, не уверен, что я полностью понимаю, о чем вы просите, но, надеюсь, первый тоже исправляет это. – Noseratio
Спасибо, @Noseratio. Браузеру FC нужны некоторые ключи, которые должны быть записаны в реестре. Я не эксперт в области безопасности Windows, но я подумал, что, возможно, для этого потребуются права учетной записи пользователя, и это то, чего я пытаюсь избежать с помощью «IE = edge». Мой первый вопрос: если это будет иметь тот же эффект, что и браузерный FC. Может быть, я ошибаюсь, и никаких прав учетной записи не требуется? Я уточню вопрос – Miquel
никаких прав администратора, необходимых для 'HKEY_CURRENT_USER'. – Noseratio
