Check Device Manager for three common visibility patterns: no Bluetooth category, a grayed-out Bluetooth radio, or a Bluetooth device with a warning icon. In each case, start by checking whether the adapter is present, disabled, or needs driver attention. This guide covers the basic checks in Windows 10 and Windows 11. Microsoft support lists Windows 11 and Windows 10 as supported systems. (Microsoft Support) (Microsoft Support)
What it means when Bluetooth is missing from Device Manager
When Bluetooth is absent from Device Manager, check whether the PC has Bluetooth hardware, whether the adapter is disabled, or whether Windows is not detecting it correctly. On Windows 11, Bluetooth settings live under Bluetooth & devices; on Windows 10, the settings path is different.
How Device Manager should usually show Bluetooth hardware
A working built-in radio normally appears under Bluetooth. If it is disabled, it may appear dimmed or may not be visible until hidden devices are shown.
Why the adapter may appear under Bluetooth or Network adapters
Bluetooth hardware can appear in Network adapters on some systems, so check both categories before concluding the adapter is missing.
What a missing entry can tell you right away
If Device Manager shows neither Bluetooth nor any likely adapter under Network adapters, the PC may not have Bluetooth hardware, or Windows may not be detecting it yet.

Which cause is most likely?
Use the table below to narrow down what to check next.
| Symptom | Possible cause | Expected Device Manager location | Next action for Windows 10 and Windows 11 |
|---|---|---|---|
| Bluetooth is absent from Device Manager | The PC may not have Bluetooth hardware, or Windows may not be detecting it | Nothing under Bluetooth; sometimes an entry under Network adapters | Check whether the PC model includes Bluetooth, then show hidden devices and scan for hardware changes |
| Bluetooth appears under Network adapters instead of Bluetooth | The adapter may be present but disabled or not fully initialized | Network adapters | Open Device Manager, view hidden devices, and check Bluetooth in Settings or quick settings |
| Bluetooth settings are missing in Windows | The driver may be missing or Windows may not be detecting the hardware | Bluetooth may be missing or may have a warning icon | Recheck Device Manager, then install the correct driver if the adapter is present |
| Bluetooth disappeared after an update or repair | The adapter may be hidden, disabled, or affected by a damaged driver or system file | Bluetooth or Network adapters may both look incomplete | Run DISM and SFC, then check the adapter again |
Is your PC missing Bluetooth hardware?
If the PC never had Bluetooth, Device Manager will not create the adapter entry. If the machine does have Bluetooth hardware, a USB Bluetooth adapter may also need the right driver before Windows shows it. Start by identifying which of those two cases applies.
Confirm whether the PC was built with Bluetooth
- Open Win+X > Device Manager.
- Expand Network adapters and Bluetooth.
- Look for a wireless radio name, not only Wi-Fi.
- Open Settings > Bluetooth & devices on Windows 11, or the Bluetooth page in Windows 10.
- If no Bluetooth controls exist, treat hardware absence as a real possibility.
Confirm whether you are using a USB Bluetooth adapter
If a desktop has no built-in radio and you add a small USB dongle, Windows may not show it until the correct driver is installed. That does not by itself mean the dongle is defective.
What to expect if the hardware is not present
If the PC lacks Bluetooth hardware, Device Manager will not show a Bluetooth category, Settings may omit the Bluetooth toggle, and pairing will not start in Bluetooth & devices.
How do you fix a hidden, disabled, or badly detected adapter?
A hidden or disabled adapter can come back after a rescan, a settings change, or a reboot. On Windows 11, Bluetooth can also be turned on from quick settings. On Windows 10, use the Bluetooth settings page.
Show hidden devices and scan for hardware changes
- Open Device Manager.
- Select View > Show hidden devices.
- Expand Bluetooth and Network adapters.
- Use Action > Scan for hardware changes, or right-click the computer name at the top of Device Manager and choose Scan for hardware changes.
- If it appears faded, right-click it and choose Enable device if available.
Check Bluetooth in Windows 10 settings
- Open Settings > Devices > Bluetooth & other devices.
- Turn Bluetooth On.
- If the page is missing Bluetooth entirely, return to Device Manager and check hardware presence.
- Reboot after changing the setting.
Check Bluetooth & devices in Windows 11
- Open Settings > Bluetooth & devices.
- Confirm Bluetooth is switched On.
- Open Quick settings from the taskbar and add the Bluetooth tile if it is missing.
- Use the tile to toggle Bluetooth off and on once.
Look for the quick settings Bluetooth tile on Windows 11
Windows 11 may hide the Bluetooth tile. If the tile is missing, add it from quick settings, then use it to confirm the radio state.
What if the driver is missing or broken?
If the adapter appears with a warning symbol, or the Bluetooth page is missing even though hardware should be present, install the correct driver for the exact adapter model. A generic Windows update is often not enough.
Install the correct vendor driver for the exact adapter model
- Open Device Manager and note the device name from the General tab or from the entry itself.
- Open the OEM or chipset vendor support site for that exact model.
- Download the Bluetooth driver that matches your Windows version.
- Run the installer, or use Update driver from Device Manager if the package is already on the PC.
- Reboot after installation.
Remove bad driver entries and retry detection
- Open Device Manager.
- Right-click the Bluetooth device or unknown device.
- Choose Uninstall device.
- If offered, check Delete the driver software for this device when the driver is corrupted.
- Restart the PC, then rescan hardware.
Win+X > Device Manager > device > right-click > Properties
Actions: Update driver, Roll Back Driver, Uninstall device
Use the OEM/chipset vendor site when Windows Update has no newer driver
Device Manager > View > Show hidden devices
When should you try DISM and SFC?
Use DISM and SFC when Device Manager and Settings both look wrong, or when Bluetooth disappeared after an update and reinstalling the driver does not restore it. Those commands can repair damaged system files, but they cannot create missing Bluetooth hardware.
Run DISM and then SFC
- Open an elevated Command Prompt or Windows Terminal.
- Run
DISM /Online /Cleanup-Image /RestoreHealth. - After DISM completes, run
sfc /scannow. - Restart the PC and check Device Manager again.
If Bluetooth appears under Network adapters one day and then disappears after a feature update, the adapter may be hidden, the driver may be damaged, or Windows may not be loading it correctly.
A common first-time mistake is reinstalling every Bluetooth package on the page. Start with the exact adapter name in Device Manager, then match the driver to that hardware.
If that didn’t work, try this next
If the adapter still does not appear, move from software checks to hardware verification. Try the same USB Bluetooth adapter on another Windows PC, or test a different known-good adapter on the problem PC. If neither device appears after driver repair and a rescan, suspect a hardware fault or a board-level issue. At that point, vendor support or a repair shop is the better next stop.
Prevention
Keep the exact Bluetooth driver package for your PC model saved before major updates. That gives you a clean reinstall path if the adapter disappears again.
Frequently asked questions
what to do if bluetooth is not showing in device manager
Open Device Manager, turn on View > Show hidden devices, then check Network adapters and Bluetooth. If nothing appears, verify the PC actually has Bluetooth hardware. If it does, install the exact OEM Bluetooth driver and reboot before checking again.
why is bluetooth not showing in device manager
Windows may not be detecting the adapter, the driver may not be bound, or the adapter may be disabled or hidden. Check Settings > Bluetooth & devices on Windows 11 or Settings > Devices > Bluetooth & other devices on Windows 10, then rescan hardware in Device Manager.
why is my bluetooth adapter not showing in device manager
A built-in adapter can disappear if its driver is missing or broken, while a USB dongle may stay invisible until its package installs. Open the device in Properties, then use Update driver or uninstall and reinstall the exact vendor driver.
should bluetooth appear under network adapters or bluetooth in Windows
Usually Bluetooth appears under Bluetooth, but it can also show under Network adapters on some systems. That is why you should inspect both categories before assuming the hardware is gone.
what does it mean when the bluetooth setting is missing
It usually means Windows does not see a Bluetooth adapter, or the driver is missing. On Windows 11, the control center is Bluetooth & devices; on Windows 10, it is a different settings path. If the setting never appears, check hardware and driver status first.
can a usb bluetooth adapter show up only after driver installation
Yes. Some USB Bluetooth adapters need their driver installed before Windows shows them. If the adapter is brand-specific, use the vendor’s package, then unplug and reconnect the dongle after the reboot.
