If you have had recent power outages, viruses or other computer problems, it is likely that the drivers have become damaged. Browse the list above to find the driver that matches your hardware and operating system. To see more matches, use our custom driver search engine to find the exact driver.

Tech Tip: If you are having trouble deciding which is the right driver, try the Driver Update Utility for USB Serial Port (COM1). It is a software utility that will find the right driver for you - automatically.

DriverGuide maintains an extensive archive of Windows drivers available for free download. We employ a team from around the world which adds hundreds of new drivers to our site every day.

How to Install Drivers

Once you download your new driver, then you need to install it. To install a driver in Windows, you will need to use a built-in utility called Device Manager. It allows you to see all of the devices recognized by your system, and the drivers associated with them.

Open Device Manager

  • In Windows 10 & Windows 8.1, right-click the Start menu and select Device Manager

  • In Windows 8, swipe up from the bottom, or right-click anywhere on the desktop and choose "All Apps" -> swipe or scroll right and choose "Control Panel" (under Windows System section) -> Hardware and Sound -> Device Manager

  • In Windows 7, click Start -> Control Panel -> Hardware and Sound -> Device Manager

  • In Windows Vista, click Start -> Control Panel -> System and Maintenance -> Device Manager

  • In Windows XP, click Start -> Control Panel -> Performance and Maintenance -> System -> Hardware tab -> Device Manager button

Install Drivers With Device Manager

  1. Locate the device and model that is having the issue and double-click on it to open the Properties dialog box.

  2. Select the Driver tab.

  3. Click the Update Driver button and follow the instructions.

In most cases, you will need to reboot your computer in order for the driver update to take effect.

Visit our Driver Support Page for helpful step-by-step videos

If you are having trouble finding the right driver, stop searching and fix driver problems faster with the Automatic Driver Update Utility. Many computer problems are caused by missing or outdated device drivers, especially in Windows 10. If your deskttop or laptop is running slow, or keeps crashing or hanging, there is a good chance that updating your drivers will fix the problem. Automatic updates could save you hours of time.
