Your Windows computer has Bluetooth if Settings shows a Bluetooth on/off switch, and Device Manager confirms it with a Bluetooth category listing an adapter.
This guide covers both checks on Windows 11 and Windows 10, a PowerShell check, how to confirm Bluetooth on a Mac, what to do when Bluetooth is missing, and how to add it with a USB adapter.
Check for Bluetooth in Windows Settings
The Settings path differs between Windows 11 and Windows 10, so check which Windows version you have if you are unsure.
- Select Start > Settings.
- On Windows 11, select Bluetooth & devices; on Windows 10, select Devices > Bluetooth & other devices.
- Look for a Bluetooth switch at the top of the page.
- If the switch is there, your computer has Bluetooth; turn it On to use it.
On Windows 11, the Bluetooth tile in quick settings (the network, sound and battery icons on the taskbar) is a second sign. On Windows 10, look for the Bluetooth tile in the action center. Steps to turn Bluetooth on in Windows 11 cover every switch.
Which check should you use?
| Your situation | Use this check | Why |
|---|---|---|
| Quick look on Windows | Settings | One page shows the switch |
| Settings shows no Bluetooth switch | Device Manager | Shows whether hardware exists but is disabled or missing a driver |
| Checking many PCs or a remote PC | PowerShell Get-PnpDevice | One command, text output |
| Mac | System Settings > Bluetooth | Shows Bluetooth status and connected devices |
| Buying a new computer | Maker's product specifications | Some devices ship without Bluetooth |
Use Device Manager to Confirm Bluetooth Hardware
- Select Search on the taskbar, type device manager and open Device Manager.
- Look for a Bluetooth category and expand it.
- Find the Bluetooth adapter, whose name may include the word radio.
- If there is no Bluetooth category, expand Other devices and look for an unknown or Bluetooth entry.
- Select Action > Scan for hardware changes if nothing appears, then check again.
An adapter under Bluetooth means the hardware exists. An entry only under Other devices means the hardware is there but its driver is missing.
What the Device Manager results mean
| What you see | What it means | Next step |
|---|---|---|
| Bluetooth category with an adapter, and a switch in Settings | Bluetooth is installed and working | Turn it on in Settings |
| Bluetooth category with an adapter, but no switch in Settings | The adapter is disabled or its driver is faulty | Right-click it and select Enable device if offered, otherwise update or reinstall the driver |
| Unknown device under Other devices | Hardware present, driver missing | Install the driver from the PC maker's website |
| No Bluetooth category and nothing in Other devices | No Bluetooth hardware detected | Check the maker's specifications or add a USB adapter |
Check for Bluetooth with PowerShell
Open Windows PowerShell from Start and run this command. It lists Bluetooth-class devices that are currently connected.
Get-PnpDevice -Class Bluetooth -PresentOnlyGet-PnpDevice lists Plug and Play devices; -Class filters by device class and -PresentOnly hides devices that are no longer attached.
You should see: One or more rows with a Status of OK mean a working Bluetooth adapter is present. No output means Windows sees no Bluetooth device.
Check Bluetooth Availability on a Mac
- Choose Apple menu > System Settings.
- Click Bluetooth in the sidebar; you may need to scroll down.
- Confirm the Bluetooth switch and your device list appear.
- For a hardware report, choose Apple menu > System Settings > General > About, then click System Report.
- Look through the hardware list in the report for the Bluetooth entry.
You can also hold Option and choose Apple menu > System Information to open the same report. The Bluetooth status menu in Control Center is a third place to check.
Look for Physical or Manufacturer Indicators
| Where to look | What it tells you |
|---|---|
| The maker's product specification page for your exact model | The definitive answer; Microsoft notes some devices don't have Bluetooth |
| A physical wireless or Bluetooth switch on a laptop | The laptop has a radio, and the switch must be on for Windows to see it |
| Settings shows Bluetooth but Device Manager does not | Usually a driver or disabled-device problem, not missing hardware |
| A desktop motherboard without a wireless card | Many desktops need an add-in card or USB adapter for Bluetooth |
Search the maker's support site for your exact model number rather than the product family, since one family can ship with and without wireless cards.
Troubleshoot Missing or Disabled Bluetooth
No Bluetooth switch in Settings
Airplane mode, a physical switch, a disabled adapter or a missing driver.
- Turn off Airplane mode in quick settings.
- Flip any physical wireless switch on the laptop to on.
- In Device Manager, right-click the Bluetooth adapter and select Enable device if it is disabled.
- Run the Bluetooth troubleshooter from Settings > System > Troubleshoot > Other troubleshooters > Bluetooth > Run.
Bluetooth not showing in Device Manager
The driver is missing, or the hardware is not present.
- Check Other devices for an unknown device.
- Select Action > Scan for hardware changes.
- Download the latest Bluetooth driver from your PC maker's website and install it.
- If nothing appears after that, check the maker's specifications for your model.
Bluetooth toggle missing on a PC that used to have it
A driver built for an earlier Windows version, often after an upgrade or update.
- In Device Manager, right-click the Bluetooth adapter and select Update driver > Search automatically for updated driver software.
- If that fails, right-click the adapter and select Uninstall device > Uninstall.
- Select Start > Power > Shut down, wait a few seconds, and turn the PC back on.
- Let Windows reinstall the driver, or use Action > Scan for hardware changes.
Use a USB Bluetooth Adapter if Your Computer Does Not Have Bluetooth
- Buy a USB Bluetooth adapter that lists your version of Windows as supported.
- Plug it into a USB port, away from USB 3.0 devices, since unshielded USB devices can interfere with Bluetooth.
- Wait for Windows to install the driver; if it does not, install the driver from the adapter maker's website.
- Open Settings > Bluetooth & devices and confirm the Bluetooth switch now appears.
- Select Add device > Bluetooth to pair your first accessory.
Frequently Asked Questions
How do I check if my computer has Bluetooth?
On Windows, open Settings and look for a Bluetooth switch under Bluetooth & devices on Windows 11 or Devices on Windows 10. Then confirm in Device Manager that a Bluetooth category lists an adapter. On a Mac, open System Settings and click Bluetooth.
How do I know if my Windows PC has Bluetooth built in?
Open Device Manager and expand the Bluetooth category. A listed adapter, often with radio in its name, means Bluetooth is built in. The maker's specification page for your exact model is the final word, because some devices ship without Bluetooth.
What does it mean if Bluetooth is not showing in Device Manager?
Either the driver is missing or the PC has no Bluetooth hardware. Check Other devices for an unknown entry and run Scan for hardware changes. If nothing appears after installing the maker's driver, the computer most likely lacks Bluetooth.
How can I check if my Mac has Bluetooth?
Choose Apple menu > System Settings and click Bluetooth in the sidebar. You can also open System Report from System Settings > General > About to view the hardware installed in your Mac.
Can I add Bluetooth to a computer that does not have it?
Yes. Plug in a USB Bluetooth adapter that supports your Windows version. Windows usually installs its driver automatically, and the Bluetooth switch then appears in Settings so you can pair devices.
Why is my Bluetooth toggle missing even though my computer used to have Bluetooth?
A driver problem after a Windows update or upgrade is the most common cause. Update the Bluetooth driver in Device Manager, or uninstall the adapter, shut down, restart, and let Windows reinstall it. Also check Airplane mode and any physical wireless switch.
How do I check my computer specs to see if it has Bluetooth?
Look up your exact model number on the manufacturer's support website. The specification sheet lists wireless features, including whether Bluetooth is included, and Device Manager confirms what Windows actually detects.
Bottom Line
Check Settings for a Bluetooth switch first, and use Device Manager to tell missing hardware apart from a disabled device or a missing driver. A missing switch alone does not prove the hardware is absent; Device Manager and the maker's specifications settle it, and a USB adapter adds Bluetooth if it truly is not there.
