Scan for Driver Updates

Obd-diag Port Devices Drivers

Click SCAN to start. You can STOP the scan and re-scan at any time you want.

Obd-diag port devices drivers
  • By default, Driver Booster scans automatically when it's launched. Go to Settings to disable the automatic scan if you dislike it.
  • You can also set your own driver-scan priority in Settings: the latest driver or the stable driver.
  • Scan Result

    You can see the total quantity of outdated device drivers and outdated game components at the top of the scan results screen. The scan result depends on your PC condition. And Driver Booster scans for 4 issues:

    • Outdated drivers, dates of both the current version and available version are provided.
    • Missing drivers, the current status is 'Missing Driver'.
    • Faulty drivers, the current status is 'Faulty '.
    • Not-installed game components, the current status is 'Not Installed'.

    Update Drivers

    You can follow either of the methods below to start the update:

    • Click Update Now at the top right to update all selected drivers.
    • Click Update at the right side of each driver line to update drivers one by one.

    Generally, there are 3 stages for driver update:

    1. Download drivers. With breakpoint resume technology, you are allowed to stop anytime and Driver Booster will continue the download next time instead of starting over again.
    2. Create a restore point. If you disable the option 'Automatically create a system restore point before a driver is installed' in Settings, this stage will be skipped.
    3. Install the downloaded drivers.

    Note: For PRO users, there may be one more stage – automatically back up a driver before it is installed. Check it in Settings:

    The time needed for the update depends on driver size and download speed. You can choose Automatically reboot PC or Automatically shut down PC on the updating screen, and click the icon at the top right to minimize the whole window, then leave it and forget it. After it's completed, you will get a countdown message to reboot PC or shut down PC accordingly.


    Boost module in Driver Booster offers two features: Game Boost and System Optimize.

    Game Boost

    Game Boost stops unnecessary apps/services to help you get a better gaming experience. It has two modes: Super Boost and Basic Boost.

    For Basic Boost, some unnecessary services/processes are already selected by default, so you can just click Turn On to boost. Or you can click the Configure text link and select the items you want to stop to boost your game performance.

    After the boost, you can click the Details text link to view all the stopped processes/services/apps. And you can click the Turn Off button to turn off Game Boost at any time.

    Restore Driver Updates

    To minimize the bad effect of any unexpected issues caused by driver updates, Driver Booster provides 3 strategies for easy repair: Driver Roll Back, Driver Restore, and System Restore.

    Driver Roll Back

    In the scan result window of Driver Booster, you can click the button at the end of every listed outdated driver, and select Roll Back, if it is available, to roll back the driver to its previous version.

    And you can also click the version link (Available or Current) to open Drivers Details window to check whether you can roll back the driver to its previous version.

    Driver Restore

    To restore a driver, there has to be a driver backup first. Driver backup feature included in Driver Booster can help you back up drivers so that you can restore drivers when you need to. For how it works, please see the following information.

    Note: Driver Backup works for PRO users only.

    Click the icon on the left side of the main interface and open Backup & Restore. If there is any driver version available for backup, it will be listed under the Driver Backup tab. To back them up, just tick the checkbox before them and click the Back Up button. Backup Version indicates the version you backed up for that driver while Current Version means the driver version you install at present. If you find Current Version is newer than Backup Version, you can back up that driver again to its latest installed version.

    In the Driver Restore tab, you can select the driver you want to restore and click the Restore button to re-install the backed up (the previous) version.

    System Restore

    Note: Restoring system will undo all changes made after that restore point. Driver Booster supports manually creating or removing restore points.

    Driver Booster creates a restore point before updating the driver by default. Choose a restore point according to Date and Time or Description to restore the system to the previous good state.

    Ignore Unwanted Updates

    If there is any driver you don't want to update, you can click the button at the right side of a driver line, and select Ignore to ignore either this driver update or all updates of this device.

    The ignored drivers won't be scanned for the corresponding updates until you recover them from the Ignored list in Settings:

    Driver Update History

    Click the icon at the top left of the main interface and select Driver Update History to check what operation you did about your drivers and components with Driver Booster.

    Silent Mode

    Silent Mode can help you a lot when you want to focus on what you are doing. Once you select the option Silent Mode in Settings, Driver Booster will automatically turn to silent mode when your full-screen task or specified program/game is running, which means you will not receive any notification from Driver Booster.

    If any program or game you want to stay focused on, just add it to My Specified Programs/Games list. You can also delete any program or game from the list as per your own needs.

    Configure UI

    Click the icon, you will see the Skin options at the bottom left of the popup window.

    And you can click Settings to quickly change Language, and Transparency under General.
