Video Codecs, for example, might show MPEG or Cinepak devices and settings. Problem Devices identifies components that aren't working properly. The information is taken from the Device Manager. Problem Devices is helpful because it puts all the problem devices together in one place, which saves you time over looking through the Device Manager, where you'll also see all properly functioning devices. Problem Devices shows the name of each problem device along with its status.
History keeps track of all component activity.
If you recall that problems began developing about four days ago, for example, you could call up the last seven days' component history to help you remember which devices were installed over that period of time.
