NeoSmart Technologies and PROnetworks recently worked together on a much wanted application for Vista. This program is mainly a User Interface to modify Vista's bootloader behaviour and settings. The main modifications it can operate are adding an entry, modify it, or remove one of them easily. The biggest features of it are for sure Bootloader removing and backups support.
Particularly useful as Microsoft bloated the bcdedit Boot loader editor with crypted and misleading commands. Another nice touch about it is that it can be used to recover a broken Windows installation if the problem is related to boot sector.
