Results for the Driver Verification Assessment

Updated: May 31, 2012

The Driver Verification assessment helps you verify that your offline Windows® image or a running Windows operating system contains the correct set of drivers. The results help you identify issues such as missing, unnecessary and outdated drivers.

For more information about system requirements and assessment settings, see Driver Verification.

Some assessments have goals for the metrics that are captured and displayed in the Results View. The metric is usually the measure of an activity. When the metric value is compared to the goal for that metric, the status is color coded in the Result View as follows:

  • Green means that the system has a great user experience and that there are no perceived problems.

  • Yellow means that the user experience is tolerable and you can optimize the system. Review the recommendations and analysis to see what improvements can be made to the system. These can be software changes, configuration changes or hardware changes.

  • Red means that the system has a poor user experience and that there is significant room for improvements. Review the recommendations and analytsis to see the improvements that can be made to the system. These can be software changes, configuration changes or hardware changes. You might have to consider making tradeoffs to deliver a high quality Windows experience.

  • No color means that there are no goals defined for the metric.

Goals are an invaluable triage tool that helps you understand how the system is performing. A default set of goals is provided when you install the assessments. Unlike the Windows Hardware Certification tests which provide pass/fail results, the assessment goals are only recommendations.

The default goals are defined for primary metrics which measure user experiences. These goals directly correlate to perceivable quality indicators. We recommend that you use the default goals file. However, you can also define your own goals. For example, goals for a basic laptop might be different than the goals you set for a high end desktop computer, or market expectations might change in such a way that you want the flexibility to define different goals and key requirements as time passes and technology improves.

The first time that you view results in the Windows® Assessment Console or the Windows® Assessment Services - Client (Windows ASC), the default goals file is used. If you define your own goals you can use the UI to set the custom goals file location and then select the custom goals file that you want to use. You must set the goals file location and add a goals file to that location before you can use the UI to apply the custom goals. Once a new goals file is selected it will continue to be the goals file that is used for any results that are opened. The assessment tools always look for the last goals file that was used. If the goals file is no longer available the default goals file is used.

Only one goals file can be used at a time. Goals for all assessments are set in a single goals file. The assessment tools will search for goals in the following order:

  1. A custom goals file

  2. The default goals file

  3. Goals that are defined in the results file

  4. Goals that are defined in the assessment manifest

You can use the sample goals file that is provided at %PROGRAMFILES%\Windows Kits\8.0\Assessment and Deployment Kit\Windows Assessment Toolkit\SDK\Samples\Goals to create your own goals file.

noteNote
You cannot package a goals file with a job, but you can store it on a share for others to use.

The Driver Verification assessment evaluates the drivers on your computer and produces results that can help you manage the drivers that are installed. The following table describes the metrics that are available after you run the Driver Verification assessment.

 

Metric Description

All Devices

Lists all devices that the assessment discovered. You can expand the metric to see a list of devices and to identify the device name and device class.

Devices with Other Issues

The number of devices that have other issues than those specifically listed in this table.

Devices Missing Drivers

The number of devices that have missing drivers. You can expand this metric to see a list of the devices that are missing a driver and to identify the device names and device classes.

Devices with Driver Updates Available

The number of devices that have driver updates available. You can expand this metric to see a list of devices and to identify the device name, a better driver, the driver file, the driver vendor and the driver version.

Devices with Multiple Drivers

The number of devices that have multiple drivers. You can expand this metric to see a list of devices with more than one associated driver and to identify the device name and device class.

Legacy Devices

The number of devices that were identified as legacy devices. You can expand this metric to see a list of legacy devices and to identify the device name, device class, device description, instance ID and device manufacturer.

Unnecessary Drivers

The number of devices that have unnecessary software drivers that are not associated with any hardware device. You can expand this metric to see a list of unnecessary drivers and to identify the driver file, driver description driver vendor, and driver versions.

The Driver Verification assessment identifies issues with drivers, provides information about the way that these issues affect the system, and suggests possible resolutions. The following issues and recommendations can appear after you run the Driver Verification assessment. Issue descriptions, recommendations and links to additional information are also available in the UI.

 

Issue Description Recommendation

Missing Driver

There was no driver found for this device. The device will not work without the appropriate driver.

When connected to the Internet, search Windows Update for the driver for this device. To automatically search Windows Update for missing drivers, run the assessment again while connected to the Internet and use the default settings. In some cases you might have to contact the OEM or the device manufacturer to obtain the driver.

Multiple Drivers

Lists devices with more than one available driver.

Extra drivers waste space and can contain vulnerabilities that compromise computer security. We recommend that you include only required drivers. Remove the extra drivers from the offline image by using DISM, or uninstall the drivers from the running computer by using Device Manager. For more information about how to use DISM to remove drivers, see Driver Servicing Command-Line Options.

Unnecessary Drivers

Lists drivers not associated with any of the available hardware devices. Unnecessary drivers could be either a software or service driver.

If you do not use this software or service, consider removing it. Extra drivers can be removed offline using DISM, or by using Device Manager. See Driver Servicing Command-Line Options.

Updated Better Driver

An updated driver is available.

We recommend that you update the driver for optimal device functionality. There is a more up-to-date driver available on Windows Update. Use the provided link to download the driver or contact the device manufacturer for additional updates. See Windows Update Driver Publishing for information about how to use Windows Update.

Legacy Devices

Lists the devices that do not have a Plug and Play ID.

The Microsoft Device Association Root Enumerator device does not have a Plug and Play ID. Such devices cannot be evaluated by this assessment. Use alternative methods to verify the functionality of this device.
