Windows 10 automatically installs drivers for devices that connect to it, but only when those drivers are available on your PC or through Windows Update. In most cases, though, Bluetooth devices (especially keyboards and mice) should work fine right out of the box.

If Windows can’t find the correct drivers for your Bluetooth device, however, it won’t work. If this happens, check the device manufacturer’s website to see if it offers a driver for your device. If so, download and install it, and that should resolve the problem.

This also applies to the Bluetooth radio itself. If the drivers for your Bluetooth chipset aren’t installed automatically, Bluetooth won’t work on your PC. Visit the PC manufacturer’s website or, if you built the PC yourself, check the motherboard manufacturer’s website for supported drivers.

You might also find that a new Windows update has impacted your device, requiring updated drivers. In most cases, Windows will look for and install updated drivers automatically. If it doesn’t, though, visit the device manufacturer’s website and install the latest drivers.

To see whether your Bluetooth device is installed, you have to check the Windows Device Manager. To do this, right-click the Windows Start button and click “Device Manager”.

If your Bluetooth device is recognized, it appears under the category relevant to its purpose. For example, a Bluetooth radio would be under the “Bluetooth” category. If the device isn’t recognized, it will be listed under the “Other Devices” category.

When you find it, right-click the device, and then click “Update Driver” to search for a new driver.

Click “Search Automatically for Updated Driver Software” if you want to search for a driver automatically. If you downloaded the driver from the manufacturer’s website (and it doesn’t include an automatic installer), click “Browse My Computer for Driver Software” and follow the onscreen instructions.

If you clicked “Search Automatically for Updated Driver Software,” Windows will tell you if it thinks you already have the best driver for your device. However, you can also search Windows Update for alternatives.

To do so, just click “Search for Updated Drivers on Windows Update” to proceed.

This opens Windows Update in Settings. Click “Check for Updates” to begin a search. When (or if) Windows Update finds an updated driver for your device, it will download and install it. When that process is complete, restart your PC, and then try your Bluetooth device again.
