Bluetooth is usually already on your PC — you just need to turn it on

Most new PCs come with Bluetooth hardware built in, but the feature is often switched off by default. You do not need to download Bluetooth itself. Instead, you need to check whether your PC has Bluetooth, turn it on if it is off, and then pair your device. If your PC is missing Bluetooth hardware entirely, you will need a USB adapter — a small device that plugs into a USB port and adds Bluetooth to any computer.

The steps differ slightly between Windows and Mac, but both follow the same basic path: check that Bluetooth exists, turn it on, then pair your device. Most people can get this working in under five minutes.

Key Takeaways

  • Bluetooth hardware is built into most new PCs, but you may need to turn it on in your settings rather than download anything.
  • On Windows, open Settings, go to Bluetooth & devices, and toggle Bluetooth on; on Mac, open System Settings and click Bluetooth.
  • If Bluetooth does not appear in your settings at all, your PC does not have the hardware and you will need a USB Bluetooth adapter.
  • Once Bluetooth is on, put your device (headphones, mouse, keyboard) into pairing mode and select it from your PC's Bluetooth list.
  • If pairing fails, restart both your PC and the device you are trying to connect, then try again.

Check if your PC has Bluetooth hardware

Before you do anything else, confirm that your PC actually has Bluetooth built in. Many budget PCs and older desktop computers do not. On Windows, right-click the Start button, select Device Manager, and look for "Bluetooth" in the list. If you see it, your PC has the hardware. If the list does not show Bluetooth at all, skip to the USB adapter section below.

On Mac, click the Apple menu in the top-left corner, select System Settings, then click Bluetooth. If Bluetooth appears as an option, your Mac has the hardware. If the Bluetooth option does not exist, your Mac lacks it — though this is extremely rare on modern Macs.

Turn on Bluetooth in Windows Settings

Open the Start menu and type "Bluetooth" into the search box. Click "Bluetooth and other devices settings" when it appears. You will see a toggle switch next to "Bluetooth" at the top of the window. If it is gray or shows "Off", click it to turn Bluetooth on. The toggle will turn blue and show "On".

Wait a few seconds for Bluetooth to fully activate. You should see a message that says "Bluetooth is on" or similar. If you see an error message instead, restart your PC and try again — sometimes the Bluetooth radio needs a fresh start.

Turn on Bluetooth on a Mac

Click the Apple menu in the top-left corner and select System Settings. Click "Bluetooth" in the left sidebar. You will see a toggle switch next to "Bluetooth" at the top. If it shows "Off", click it to turn Bluetooth on. The toggle will change to show "On".

On some older Macs, you may need to click the Bluetooth icon in the menu bar at the top of the screen instead. If you see a Bluetooth icon there (it looks like a stylized "B"), click it and select "Turn Bluetooth On" from the dropdown menu.

Pair your device to your PC

Once Bluetooth is on, put the device you want to connect (headphones, mouse, keyboard, speaker) into pairing mode. The method varies by device — check the manual or manufacturer website for exact steps, but most devices require you to hold down a button for three to five seconds until a light blinks or you hear a tone. Some devices have a dedicated pairing button.

On Windows, go back to Settings > Bluetooth and other devices. Click "Add device" and select "Bluetooth". Your PC will search for nearby devices. When your device appears in the list, click it. Windows will show a pairing code on your screen and on your device — confirm they match, then click "Connect". On Mac, your device should appear automatically in the Bluetooth menu. Click it and follow any prompts to complete pairing.

What to do if your PC has no Bluetooth hardware

If Bluetooth does not appear in Device Manager on Windows or in System Settings on Mac, your PC does not have Bluetooth hardware. You can add it with a USB Bluetooth adapter — a small device that costs between $10 and $30 and plugs into any available USB port. Popular options include the ASUS USB-BT500 and the TP-Link UB400, but any adapter with good reviews will work.

Plug the adapter into a USB port on your PC. Windows will automatically search for and install drivers for the adapter — this usually takes one to two minutes. Once installation is complete, the adapter will appear in Device Manager under "Bluetooth". You can then follow the steps above to turn on Bluetooth and pair your device. On Mac, most USB adapters work immediately without any driver installation.

Troubleshooting when pairing fails

If your device does not appear in the Bluetooth list, or if pairing starts but does not complete, restart both your PC and the device you are trying to connect. Wait 30 seconds after each restart, then put your device back into pairing mode and try again. This solves most pairing problems.

If the device still does not appear, check that it is fully charged — many devices will not enter pairing mode if the battery is very low. Also confirm that you are following the correct pairing steps for your specific device; some require you to hold a button longer than others, or to press multiple buttons in sequence. If you are still stuck, check the device manufacturer's support page for your model number.

Frequently Asked Questions

Do I need to download a Bluetooth driver?

Most new PCs come with Bluetooth drivers already installed. If you are using a USB Bluetooth adapter, Windows will usually find and install the driver automatically when you plug it in. You only need to manually download a driver if Windows tells you it cannot find one — in that case, visit the adapter manufacturer's website and download the driver for your specific model.

Why does my PC say Bluetooth is on but I cannot see my device?

Make sure your device is in pairing mode — this is the most common reason devices do not show up. Also check that your device is within 30 feet of your PC and that nothing is blocking the signal. If you have paired the device before, it may try to reconnect to an old device instead of your PC. Restart your device and try pairing again.

Can I use Bluetooth on a desktop PC?

Desktop PCs rarely have Bluetooth built in, but you can add it with a USB adapter. Plug the adapter into any USB port on your desktop tower or monitor, and your PC will treat it the same as built-in Bluetooth. The adapter will work with any Bluetooth device — headphones, mice, keyboards, speakers, and more.

What if Bluetooth keeps disconnecting?

Move your device closer to your PC — Bluetooth works best within 10 to 15 feet. If disconnections continue, restart your PC and the device, then re-pair them. If one specific device keeps disconnecting, try removing it from your Bluetooth list and pairing it again from scratch. On Windows, go to Settings > Bluetooth and other devices, find the device, click it, and select "Remove device".

Is Bluetooth safe to use on my PC?

Bluetooth is secure for everyday use like connecting headphones or a mouse. The connection is encrypted, so other people cannot easily intercept your data. However, avoid using Bluetooth for sensitive activities like banking on public networks. If you are concerned about privacy, you can turn Bluetooth off when you are not using it — it does not affect your internet connection or other PC functions.
