Where to find your installed drivers
The fastest way to see what drivers are installed on your computer is through Device Manager, a built-in Windows tool that lists every piece of hardware and shows which driver is running it. On Windows 10 or 11, right-click the Start button in the bottom left corner, then select Device Manager from the menu that appears. If you do not see it there, type "Device Manager" into the search box next to the Start button and click the result.
Once Device Manager opens, you will see a list of hardware categories — things like "Display adapters", "Network adapters", "Sound, video and game controllers", and "Universal Serial Bus controllers". Each category can be expanded by clicking the arrow or plus sign next to it. When you expand a category, you will see the specific devices underneath. For example, expanding "Display adapters" might show "NVIDIA GeForce GTX 1650" or "Intel Iris Xe Graphics".
On a Mac, drivers work differently because macOS handles most hardware automatically. To see what hardware is connected, click the Apple menu in the top left, select About This Mac, then click the System Report button. This shows your hardware, though it does not display driver versions the way Windows does.
Key Takeaways
- Device Manager on Windows shows every piece of hardware and which driver is running it — open it by right-clicking the Start button or searching for it by name.
- Expand each hardware category to see the specific devices, and a small triangle or exclamation mark next to a device means the driver has a problem.
- Right-click any device and select Properties to see the driver version, manufacturer, and the date it was installed.
- If a device shows a yellow warning symbol, the driver is either missing, outdated, or conflicting with another driver, and Windows usually offers a fix through the Properties window.
- Checking drivers regularly helps you spot hardware problems before they cause crashes or performance slowdowns.
How to see driver details for a specific device
Once you have found a device in Device Manager, right-click on it and select Properties. A window will open showing several tabs. The Driver tab is what you need — it displays the driver name, version number, date, and the company that made it. This is the information you need if you ever have to update or reinstall a driver.
The version number matters because older drivers sometimes cause crashes or do not work with new software. If you see a date from several years ago, that driver may be outdated. The Driver Details button on the same tab shows the actual file name and location of the driver on your hard drive, though you rarely need this information unless you are troubleshooting a serious problem.
What warning symbols mean
If a device has a yellow triangle with an exclamation mark next to it, Windows is telling you something is wrong. This usually means the driver is missing, corrupted, or conflicting with another driver. Right-click the device and select Update driver — Windows will search for a newer version online and install it automatically.
A red X means the device is disabled or the driver failed to load. Right-click the device and select Enable device to turn it back on. If that does not work, try uninstalling the driver by right-clicking and selecting Uninstall device, then restart your computer — Windows will usually reinstall a basic driver automatically when it boots back up.
If you see no symbol at all, the device is working normally and the driver is loaded. A small arrow pointing down next to a device name means it is intentionally disabled, which is normal for hardware you are not using.
Checking drivers for common problem devices
The devices that cause the most trouble are graphics cards, network adapters, and audio devices. To check your graphics driver, expand Display adapters in Device Manager. If you have an NVIDIA or AMD card, the driver version matters more than with integrated graphics — these cards need regular updates to run new games and software smoothly.
For network problems, expand Network adapters and look for your WiFi or Ethernet adapter. If you are having trouble connecting to the internet, an outdated network driver is often the cause. Right-click the adapter and select Update driver to search for a newer version.
Audio issues usually point to drivers under Sound, video and game controllers. If you have no sound or crackling audio, check whether the driver is up to date. Sometimes the problem is not the driver itself but a setting in the audio control panel — right-click the speaker icon in the bottom right corner of your screen and select Open Volume mixer or Sound settings to check.
How to update drivers manually
Windows can search for driver updates automatically, but sometimes you need to update manually — especially for graphics cards or specialized hardware. First, identify the device and its manufacturer from Device Manager. Then visit the manufacturer's website directly. For example, if you have an NVIDIA graphics card, go to nvidia.com and look for a "Drivers" or "read" section.
On the manufacturer's website, you will usually need to enter your hardware model or let the site detect it automatically. read the driver file to your computer, then run the installer. The installer will guide you through the rest. After installation, restart your computer to make sure the new driver loads properly.
Some manufacturers provide driver update software that checks for new versions automatically — NVIDIA has GeForce Experience, AMD has Radeon Software, and Intel has Driver Support Assistant. These tools can be useful if you want updates to happen without thinking about it, though you can also check manually whenever you want.
When to check your drivers
You do not need to check drivers constantly, but there are specific times when it makes sense. If your computer is crashing, freezing, or running slowly, checking Device Manager for warning symbols is a good first step. If you just installed new hardware and it is not working, the driver is usually the problem. If you are having trouble with a specific program — a game that will not start, a printer that will not print, or a monitor that flickers — checking the relevant driver is worth doing.
After a major Windows update, sometimes drivers need to be reinstalled or updated. If your computer feels unstable after an update, opening Device Manager and looking for warning symbols can reveal which driver is causing trouble. You can also check drivers before selling or giving away a computer, just to make sure everything is in working order.
Frequently Asked Questions
What if I do not recognize a device name in Device Manager?
Right-click the device and select Properties, then look at the manufacturer name. You can search that name online to find out what the device is. Many devices have technical names that do not match what they are called in everyday language — for example, "PCI Express Root Complex" is part of your motherboard, not a separate device you need to worry about.
Can I delete a driver from Device Manager?
You can right-click a device and select Uninstall device, which removes the driver. When you restart your computer, Windows will usually reinstall a basic version automatically. Only do this if you are trying to fix a problem — uninstalling a driver for hardware you actually use will make that hardware stop working until the driver is reinstalled.
Why does Windows say a driver is up to date when I know there is a newer version?
Windows only searches for drivers in its own database, which does not always have the very latest versions. Manufacturers often release newer drivers on their own websites before they appear in Windows Update. If you need the newest driver, visit the manufacturer's website directly and read it from there.
Do I need to restart my computer after updating a driver?
Most driver updates require a restart to take effect. The installer will usually ask you to restart, or Windows will prompt you to do so. It is a good idea to save your work and close programs before updating drivers, just in case.
What is the difference between a driver and firmware?
A driver is software that tells Windows how to use a piece of hardware. Firmware is software that lives inside the hardware itself and controls how the hardware works at a basic level. Most of the time you only need to update drivers, but some devices like printers or routers occasionally need firmware updates too.
