Solved Device Driver Software Was Not Successfully Installed

If you see the error “Device driver software was not successfully installed,” it means Windows detected a device but couldn’t load a compatible driver for it. The fix is usually to identify the device, download the correct driver from the manufacturer’s website, and install it manually — or use Windows Update to find it automatically.

What This Error Actually Means

When you plug in a USB device, insert an expansion card, or boot a newly built PC, Windows scans the hardware and tries to find a driver — the software that lets the operating system talk to the hardware. If the search fails, or the driver it already has is incompatible or corrupted, you see the “Device driver software was not successfully installed” balloon notification from the Action Center. The device itself may still be detected, but it won’t work correctly until a proper driver is installed.

This message is different from a “Code 10” or “Code 28” error in Device Manager, though the underlying problem is similar. The notification often appears when a device uses a generic driver that doesn’t fully support the hardware, or when the driver is unsigned, old, or designed for a different version of Windows.

Common Causes

Missing driver: Windows has no built-in driver for the device and couldn’t find one via Windows Update.
Wrong driver version: You downloaded a driver for a different Windows version (e.g., 32-bit vs 64-bit) or a different model.
Corrupted driver files: A previous installation was interrupted, or the downloaded file is incomplete.
USB port or cable issues: A faulty port or cable can cause the device to disconnect mid-installation, leaving the driver half-installed.
Driver conflicts: An old driver for a similar device is interfering with the new one.

Step-by-Step Fix to Resolve the Error

Open Device Manager. Press Windows + X and select “Device Manager.” Look for a device with a yellow triangle icon — that’s the one with the problem.
Note the device name and hardware ID. Right-click the device, choose “Properties,” go to the “Details” tab, and select “Hardware IDs” from the dropdown. The values like USB\VID_046D&PID_C534 are unique identifiers that help you find the exact driver.
Search for the driver online. Use the hardware ID or the device’s model name to find the manufacturer’s support page. Download the driver for your exact Windows version (64-bit vs 32-bit). Avoid third-party driver download sites — they often bundle adware or outdated files.
Run the installer. If the driver comes as an executable, run it and follow the prompts. If it’s a folder of files, use “Update Driver” in Device Manager and point it to that folder.
Restart your PC. Many drivers load properly only after a reboot.

If the error persists, try a different USB port (preferably a port directly on the motherboard, not a hub), replace the cable, and check if the device works on another computer. If it does, the problem is with your Windows installation, not the hardware.

Using Windows Update as a Fallback

Sometimes the driver is available through Windows Update but isn’t installed automatically. To force it:

Open Settings > Windows Update > Advanced options > Optional updates.
Look under “Driver updates” — you may see the missing driver listed there. Select it and click “Download and install.”

This method works well for common devices like network adapters, audio chips, and webcams. For niche hardware (e.g., a specific RAID controller or a proprietary printer), the manufacturer’s site is still the best source.

How to Identify an Unknown Device

If Device Manager shows “Unknown device” or “Other devices,” you need to find out what it is before you can fix it. The hardware ID is your best clue. For example, PCI\VEN_10EC&DEV_8168 tells you the vendor is Realtek (10EC) and the device is the 8168 network adapter. You can search that ID in a search engine or on a site like PCI Lookup to see the device name, then go to the vendor’s site for the driver.

Another trick: unplug the device, open Device Manager, and click “Scan for hardware changes.” The device that disappears is the one you’re dealing with. This is especially useful when you have several USB devices plugged in.

When to Use the “Update Driver” Option vs. the Manufacturer’s Installer

Both methods work, but they have different strengths. The “Update Driver” option in Device Manager is good when you already have the driver files downloaded and you want Windows to install them manually. It’s also useful for forcing a driver update that Windows Update hasn’t offered.

The manufacturer’s installer (usually a .exe) is often more thorough — it may install additional software, utilities, or control panels that the bare driver doesn’t include. For example, a printer driver installer adds the print queue and scanning software, while the basic driver only lets Windows recognize the printer. If you only need basic functionality, the “Update Driver” method is fine; if you want all features, use the installer.

Frequently Asked Questions

Why does the error keep coming back after I install the driver?

This usually means the driver is being overwritten by an older version, or Windows is installing a generic driver that doesn’t work. Try uninstalling the device in Device Manager (right-click > “Uninstall device”) and check the box “Delete the driver software for this device” if it appears. Then reinstall the correct driver from the manufacturer.

Can I ignore this error if the device seems to work?

If the device functions normally, you can ignore it. Some devices, like certain USB audio interfaces, may work with a generic driver but lack advanced features. If you’re not missing any functionality, there’s no urgency to fix it.

Is it safe to use a driver from a third-party website?

It’s generally not recommended. Third-party sites may host outdated or modified drivers that can cause instability or security risks. Stick to the manufacturer’s official site or Windows Update.

What if the device doesn’t show up in Device Manager at all?

If the device isn’t listed at all, it may be completely unrecognized. Try plugging it into a different port, using a different cable, or checking if the device needs power (some external drives have their own power adapter). If it still doesn’t appear, the hardware may be faulty.

Does this error affect Windows performance?

No, it only affects the specific device. Other hardware and system performance are unaffected. The error is just a notification; it doesn’t slow down your PC.
