Check whether your PC already has Bluetooth
Most new PCs come with Bluetooth built in, but the driver — the software that lets Windows talk to the hardware — may not be installed yet. Before you read anything, check whether Bluetooth is already there and working.
Open the Start menu and type "Device Manager" into the search box, then click the result. Look for a section called "Bluetooth" in the list. If you see it and it does not have a yellow warning triangle next to it, Bluetooth is already installed and working — you can close Device Manager and move on to pairing your devices.
If you see "Bluetooth" with a yellow triangle, or if you do not see a Bluetooth section at all, the driver is missing or broken. This is what you will fix in the next steps.
Key Takeaways
- Check Device Manager first — if Bluetooth appears without a warning triangle, the driver is already installed and you do not need to read anything.
- If Bluetooth is missing or shows a yellow triangle, Windows Update usually installs the correct driver automatically when you restart your PC.
- If Windows Update does not find the driver, you can search your PC manufacturer's support website by your exact model number to read it manually.
- Once the driver is installed, Bluetooth will appear in your Settings under "Devices" and you can pair wireless headphones, mice, and keyboards.
Let Windows Update find and install the driver automatically
The easiest path is to let Windows handle it. Open Settings by pressing the Windows key and typing "Settings," then click the result. Go to "System" on the left, then scroll down and click "About." At the bottom of that page, click "Advanced system settings."
In the window that opens, click the "Hardware" tab at the top, then click "Device Manager." You should now see the same Device Manager window from before. Right-click on the Bluetooth entry (or the unknown device if Bluetooth is not labeled), and select "Update driver." Choose "Search automatically for updated driver software" and let Windows search.
Windows will connect to its driver library and install the correct one if it finds a match. This takes a few minutes. Once it finishes, restart your PC. After the restart, open Device Manager again and check whether the yellow triangle is gone. If it is, the driver is installed.
Find the driver on your PC manufacturer's website if Windows Update does not work
If Windows Update did not find a driver, you will need to read it from your PC maker's support page. You need your exact PC model number — not just "Dell" or "HP," but something like "Dell XPS 13 9370" or "HP Pavilion 15-cc."
Find your model number by opening Settings, clicking "System," then "About." Look for "Device name" or "Model" — write this down exactly. Then open a web browser and go to your manufacturer's support website. Dell, HP, Lenovo, ASUS, and others all have a "Downloads" or "Support" section where you can search by model.
Search for your model number and look for a section called "Drivers," "Software," or "Downloads." Find the Bluetooth driver in the list — it may be labeled "Bluetooth," "Wireless," or "Chipset" depending on the manufacturer. read the file to your Downloads folder.
Install the driver file you downloaded
Once the file is downloaded, open your Downloads folder and double-click the driver file. It will usually be a .exe file or a .zip file. If it is a .zip file, right-click it and select "Extract All," then double-click the extracted .exe file.
Follow the installer's prompts — most will ask you to agree to terms and then click "Install" or "Next" a few times. Let it finish completely, then restart your PC when prompted. Do not skip the restart; the driver will not work until Windows has rebooted.
After your PC restarts, open Device Manager again and check whether Bluetooth now appears without a warning triangle. If it does, the driver is installed and ready to use.
Verify Bluetooth is working in Settings
Once the driver is installed, you should see Bluetooth in your Windows Settings. Open Settings, click "Devices" on the left, then click "Bluetooth and other devices." You should see a toggle switch at the top that says "Bluetooth" — make sure it is turned on (the switch should be blue).
If the toggle is there and on, Bluetooth is working. You can now pair wireless devices like headphones, mice, or keyboards by clicking "Add device" and following the pairing steps. If the toggle does not appear even after the driver installed, restart your PC one more time — sometimes Windows needs a second restart to fully set up the feature.
What to do if Device Manager still shows a problem after installing
If you installed the driver but Device Manager still shows a yellow triangle or an error message, the driver may not be the correct one for your hardware. Go back to your manufacturer's support page and look for a different driver — sometimes there are multiple Bluetooth options listed, and you may have downloaded the wrong one.
Another common issue is that your PC's BIOS (the firmware that runs before Windows starts) may have Bluetooth disabled. Restart your PC and watch for a message during startup that says "Press F2" or "Press Del" to enter Setup or BIOS. Follow that prompt, then look for a section called "Integrated Peripherals" or "Onboard Devices" and find Bluetooth in the list. Make sure it is set to "Enabled," then save and exit. Restart Windows and check Device Manager again.
Frequently Asked Questions
Do I need to read Bluetooth if my PC is brand new?
Probably not. Most new PCs have Bluetooth hardware and the driver pre-installed. Open Device Manager and check for a Bluetooth section without a warning triangle. If you see it, you are done — no read needed. If you do not see it or it has a warning, then follow the steps above.
Where do I find my PC model number?
Open Settings, click "System," then "About." Look for "Device name" or "Model" — that is your model number. Write it down exactly as it appears, including any numbers or letters after the main name. Use this exact string when searching your manufacturer's support website.
Can I use my PC without Bluetooth if the driver will not install?
Yes. Bluetooth is optional — you can use wired USB devices instead. If the driver will not install after trying both Windows Update and your manufacturer's website, contact your PC maker's support line with your model number and the error message from Device Manager. They may have a newer driver or know of a hardware issue.
What if I downloaded the driver but the installer will not run?
Right-click the installer file and select "Run as administrator." If it still will not run, the file may be corrupted. Delete it, go back to your manufacturer's website, and read it again. Make sure you are downloading to a folder you can access easily, like your Downloads folder.
Do I need to restart my PC after installing the Bluetooth driver?
Yes, always restart after installing a driver. Windows needs to reboot to load the new driver into memory and make it active. Do not skip this step — the driver will not work until you restart.
