You are working as an administrator at an organization. All users have video capture cards and USB-connected digital video cameras connected to their computer. They have used the built-in Windows XP Professional drivers to install these devices. Last week one of the users updated her drivers from the manufacturer’s website. After the drive update, she rebooted the computer and received an error message stating that a service or driver failed to start. Once logged in, the user noticed that the video capture card and digital video camera was inaccessible. What should be your first step to get the devices to work?
  1. Restart her computer using the last known good configuration.
  2. Restart her computer by using the Recovery console and disable the new set of drivers.
  3. Select the Roll Back Driver option in the device’s properties in the Device Manager.
  4. Reseat the devices.
Explanation
Answer - C - The first and foremost thing to do while trying to get a failed device driver to update is to try to roll back the driver to a previous edition which worked.

Key Takeaway: If a hardware device stops working with the first version of the driver used, you may install an updated version to make it work. Unfortunately, this may actually do more harm than good. In such a situation (or when you try an updated driver just for the heck of testing it), you should revert to the previous version of the driver using the driver rollback feature. Each time you update a driver, Windows XP automatically saves a copy of the previous driver on a computer. Driver Rollback permits only one level of rollback (only one prior driver version can be saved at a time).This feature is available for all device classes except printers.
