      Free PowerPoint Password Recovery vs Kon-Boot opinions
      pros, cons and recent comments
      "Free PowerPoint Password Recovery" is for just that: PowerPoint (odd how it wouldn't be for OFFICE, in general, but that's another issue). Kon-Boot is for Windows, ITSELF, not a random MS Office component.
