What You Should Know About Driver Updating

There are numerous of typical warnings and other messages which you might get in the driver updating process, a number of which I've paraphrased and listed here as well as advice on how to proceed:

Windows requires a digitally signed driver: In 64-bit versions of Windows, you won't even see the above two messages because Windows won't let you install a driver that has a digital signature issue. End the driver update process and locate the correct driver from the hardware maker's website if you see this message.

Method to Update Driver with Device Manager

1. Find Control Panel.



Depending on your version of Windows, Control Panel is usually available from the Start Menu or the Apps screen.

What you do next depends on what Windows operating system you're using:

  • In Windows 10 and Windows 8, tap or click on the Hardware and Sound link.
  • In Windows 7, click System and Security.
  • In Windows Vista, choose System and Maintenance.
  • In Windows XP, click Performance and Maintenance.

Note: If you don't see these options, your Control Panel view may be set to Large icons, Small icons, or Classic View, depending on your version of Windows. If so, find and choose Device Manager from the big collection of icons you see and then skip to Step 3 below.

2. Open Device Manager

  • In Windows 10 and Windows 8, check under the Devices and Printers heading.
  • In Windows 7, look under System.
  • In Windows Vista, you'll find Device Manager towards the bottom of the window.
  • Windows XP Only: You have a few extra steps since Device Manager isn't as easily available in your version of Windows.

From the open Control Panel window, click System, choose the Hardware tab, and then click the Device Manager button.



3. With Device Manager now open, you can view a device's status, update the device drivers, or do whatever other hardware management you came here to do.
