What does Dell SupportAssist do?

There are three main actions that you can take on the Dell Support website that use the Dell SupportAssist application. When you take one of these actions, you will either be prompted to download and install Dell SupportAssist if it is not already installed or the application will automatically start and install the latest version before completing the action.

  1. Detect Product

    This is the most common use of the Dell SupportAssist app. At various points on the Dell Support website, you have the option to have your Dell product detected so that Dell can provide targeted support. When you click Detect This PC, the application runs on your computer and detects the Service Tag of your Dell computer. Dell then uses the Service Tag to look up product information, such as your original system configuration and warranty end date, to provide a product-specific support experience.

  2. Detect Drivers

    Once you have identified your product, you have the option to run a Detect Drivers (System Analysis) on the Driver & Downloads tab of the Product Support page. When you click Detect Drivers (System Analysis), Dell SupportAssist looks at which drivers are installed on your system and compares it with the latest available drivers. This is the most accurate way to determine which drivers are out of date on your system. Once the scan is complete, you can choose to "autoinstall" the updates with the Dell SupportAssist application. Similarly, Dell SupportAssist is used when you choose to download drivers from your downloads list or any time the driver size is greater than 2GB.

  3. Run Diagnostics

    You also have the option to run a diagnostic test from the Diagnostics tab of the Product Support page to detect and solve common hardware and software problems. When you click Run Diagnostic, the Dell SupportAssist application acts like a bridge between the Dell website and the Dell SupportAssist application. Dell SupportAssist helps invoke Dell diagnostic tools (SupportAssist) in the right mode and manages the progress and communications protocol between the tools seamlessly.
