    ⚠️⛔WARNING⛔⚠️ This software (at least from this specific download) is Trojan:Win32/Vigorf.A malware according to Microsoft Defender. Use iMobie, or a safer alternative instead.

    Yes, this product works fine for short password. But for long password.... 14 chars password took me 3 days to crack. It spends a lot of time for long password. Finally, I found Renee PassNow, it is easy to use and reset the password in seconds.

    Почему нельзя загрузить изображение? Разработчик не отвечает :) . Загружаю через QEMU всё загружается (графический интерфейс), но при загрузке через комп выдаёт текстовый режим. Как с ним работать , что вводить?

    The name of this beautiful piece of hand-crafted, Hackish software is as famous as its outstanding history and developers. Thank you for continuing work on this essential tool for us. It's beautifully written and developed and easy to use. =) I've always had a copy of this little gem installed no matter the OS, no matter what machine I'm using, since at least the mid-'90s or whenever I first read about it and glimpsed its masterstroke code.
