5 А Вы пробовали ChromePass v1.25 Дополнительные настройки?
Вроде там можно и с другого юзера, если знаешь пароль, но самому еще не понадобилось попробовать, интересно было бы узнать, возможно ли восстановить пароли в реальных условиях.
Reading ChromePass passwords from external drive
Starting from version 1.05, you can also read the passwords stored by Chrome Web browser from an external profile in your current operating system or from another external drive (For example: from a dead system that cannot boot anymore). In order to use this feature, you must know the last logged-on password used for this profile, because the passwords are encrypted with the SHA hash of the log-on password, and without that hash, the passwords cannot be decrypted.
You can use this feature from the UI, by selecting the 'Advanced Options' in the File menu, or from command-line, by using /external parameter. The user profile path should be something like "C:\Documents and Settings\admin" in Windows XP/2003 or "C:\users\myuser" in Windows Vista/2008
from a dead system that cannot boot anymore
Вроде Ваш случай.
