Understanding Device Drivers and Why They Matter
A device driver is a software program that allows your operating system to communicate with hardware components on your computer. Think of it as a translator between your Windows or Mac system and devices like your printer, graphics card, network adapter, or scanner. Without drivers, your operating system would not know how to send instructions to these devices or receive information from them.

According to research from tech support organizations, outdated drivers account for approximately 30-40% of hardware-related computer problems. When drivers become outdated, they may not work properly with newer versions of your operating system, leading to performance issues, error messages, or devices that stop functioning altogether.
Common problems that outdated drivers cause include:
- Printers that won't respond to print commands
- Network connections that drop or run slowly
- Audio devices producing no sound or poor quality
- Video games or graphics-heavy applications experiencing lag or crashes
- Webcams or cameras not being recognized by the system
- Mouse or keyboard responding with delays
- Display resolution options appearing grayed out or unavailable
Different manufacturers release driver updates on varying schedules. Major manufacturers like NVIDIA (graphics cards) and Intel (processors) typically release new drivers every few weeks to monthly. Smaller peripheral manufacturers may release updates less frequently, sometimes only when users report problems or when a major operating system update occurs.
Practical Takeaway: Before troubleshooting any hardware problem on your computer, consider whether a driver update might resolve the issue. Keeping drivers current is a preventative maintenance step that can extend the lifespan and reliability of your devices.
How to Identify Outdated Drivers on Windows
Windows provides built-in tools to help you see which drivers may need updating. The Device Manager application shows all hardware components recognized by your system and indicates when drivers have problems. You can open Device Manager by right-clicking the Start button and selecting "Device Manager" from the menu, or by typing "Device Manager" in the Windows search bar.

Once Device Manager opens, look for yellow exclamation marks or question marks next to any devices listed. These symbols indicate that Windows recognizes the hardware but either cannot find a driver or the current driver has an issue. Devices listed under "Other devices" without proper classification are another indicator that drivers may be missing or incorrect.
To check the driver version for a specific device:
- Right-click the device in Device Manager
- Select "Properties"
- Click the "Driver" tab
- Note the driver version and date listed
- Record the manufacturer name for later reference
Another way to identify which drivers may be outdated is to visit the manufacturer websites of your hardware components. If you have a printer from HP, for example, visit HP's support website and search for your specific printer model. The support page will show the most current driver version available. Compare this version number with what you found in Device Manager.
Many users also notice performance changes that suggest driver updates are needed. If a device suddenly stops working after a Windows update, or if you've just purchased new hardware that isn't functioning properly, outdated drivers are often the cause. Performance monitoring software can show whether specific devices are underperforming, though most users can simply observe whether their hardware works as expected.
Practical Takeaway: Open Device Manager regularly (perhaps once monthly) and scan for yellow warning symbols. Record the driver versions of your most important devices like network adapters and graphics cards so you know which manufacturers to check for updates.
How to Identify Outdated Drivers on Mac
Mac computers handle drivers differently than Windows machines. Most Mac drivers come bundled with macOS system updates rather than through separate driver installations. However, some manufacturers—particularly for printers, graphics tablets, and specialized hardware—provide their own software that includes drivers. This makes identifying outdated drivers on Mac somewhat different from the Windows process.

To check what drivers and software are installed on your Mac, open System Preferences (or System Settings on newer Mac versions) and look at each category. For printer drivers, you can navigate to Printers & Scanners to see what print drivers are currently installed. Check the manufacturer's website for your specific printer model to see if newer versions exist.
For graphics cards and other integrated hardware, Apple includes most drivers in macOS updates. To determine if you have the latest drivers, check whether your macOS system is fully updated. Go to the Apple menu, select "About This Mac," then click "System Report." This shows your current macOS version. You can then go to System Preferences and select "Software Update" to check if updates are available.
Many Mac users don't think about drivers because the system handles most driver updates automatically through macOS updates. However, if you use third-party hardware—such as gaming controllers, external audio interfaces, or professional tablets—those manufacturers often provide separate software with driver components.
To find these third-party driver updates:
- Identify each piece of non-Apple hardware you own
- Visit the manufacturer's support website
- Search for your specific device model
- Look for "Mac drivers," "software," or "downloads" sections
- Check the version information of any downloaded software
- Compare against what you see in System Preferences or Applications folder
Practical Takeaway: Make a list of all non-Apple hardware devices you regularly use (printers, external drives, input devices, etc.) and check the manufacturer's website quarterly to see if driver or software updates are available.
Step-by-Step Instructions for Updating Drivers on Windows
Windows offers multiple methods to update drivers, ranging from automatic approaches to manual updates. The easiest method is to let Windows update drivers on its own, which occurs during regular Windows Update cycles. However, you can also manually update specific drivers if you need them sooner.

Method 1: Automatic Updates Through Windows Update
Windows automatically checks for driver updates periodically and installs them during system updates. To ensure this feature is enabled, go to Settings by pressing the Windows key and typing "Settings." Select "Update & Security" (or "System" then "About" on newer Windows versions), then click "Check for updates." Windows will scan for available updates including driver updates and install them automatically or prompt you to restart.
Method 2: Manual Updates Through Device Manager
For drivers that need updating before the next Windows Update cycle, use Device Manager. Open Device Manager as described in the previous section. Right-click the device you want to update and select "Update driver." Windows will then offer two options: "Search automatically for updated driver software" or "Browse my computer for driver software." Choose the automatic search option first, which allows Windows to search online for the latest driver version.
The automatic search usually takes several minutes. During this time, Windows connects to manufacturer databases and checks for newer drivers. If an updated version is found, Windows will install it. If no newer version is available, you'll receive a message indicating that your driver is current.
Method 3: Direct Downloads From Manufacturer Websites
Some drivers, particularly for graphics cards and specialized hardware, may not be available through Windows Update. In these cases, you'll need to visit the manufacturer's website directly. For NVIDIA graphics cards, visit nvidia.com/Download. For AMD cards, go to amd.com/drivers. For Intel components, visit intel.com/content/www/us/en/support.
On the manufacturer website, select your specific device model and operating system version. Websites often use automatic detection tools that identify your hardware and system automatically. Once you locate the driver, the website will provide a file to retrieve. Save this file to your computer, then run the installer. Most driver installers guide you through the installation process with straightforward prompts.
Important considerations when updating drivers:
- Back up important files before updating drivers for critical components like storage controllers
- Disable antivirus software temporarily during installation, as some security programs interfere with driver installation
