Vista's Ultimate's PC backup is quite complete. I boot is with installation CD, and click restore from PC backup. Everything is back to normal. Of course, that means the backup has to be before virus attack. I usually keep few backups. One is the core of Vista installation; a backup right after I install Vista and activation. A backup with core software installations, like Office 2007. And finally with important software installtions and tweaks, like Flash Get, setup default download path and such.

Just beware the check box in Ultimate PC restore. I checked it and it formated my other drive that is not part of the restore drive. I lost all my precious media files because of that.
