How To Turn On Bluetooth Windows 10

Tips
1

I can’t figure out how to enable Bluetooth on my Windows 10 PC. I’ve checked the settings but I don’t see the usual Bluetooth toggle or icon anymore. I’m trying to connect wireless headphones and a mouse, but the devices won’t show up. Did I disable something by mistake, or is there another place I should look to turn Bluetooth back on?

Had the same thing happen on a friend’s Win10 laptop. Bluetooth “disappeared” and the toggle was gone. Here is what we did step by step.

  1. Check if Bluetooth is actually in Settings
  • Press Windows key + I
  • Go to Devices
  • Look on the left for “Bluetooth & other devices”
  • If you see it but no toggle, skip to step 3
  • If “Bluetooth & other devices” is missing, go to step 2
  1. Check if your PC even has Bluetooth
  • Press Windows key + X
  • Click Device Manager
  • Look for a section called “Bluetooth”
    • If you see it, expand it, note the adapter name
    • If there is no Bluetooth section, look under “Network adapters” for words like “Bluetooth” or “Wireless”
    • If you find nothing Bluetooth related, your PC might not have Bluetooth or the driver is wiped
  1. Re enable from Device Manager
  • In Device Manager, expand “Bluetooth”
  • Right click your Bluetooth adapter
  • If you see “Enable device”, click it
  • If it already says “Disable device”, Bluetooth is enabled at driver level
  1. Reinstall the driver
  • Right click the Bluetooth adapter
  • Click “Uninstall device”
  • Check “Delete the driver software for this device” if it shows
  • Click OK
  • Restart your PC
  • After restart, Windows should reinstall the driver automatically
  • If not, go to your PC or motherboard maker’s website, download the Bluetooth driver for your exact model, install it, then reboot
  1. Turn Bluetooth on in Settings
  • Press Windows key + I
  • Go to Devices
  • Click “Bluetooth & other devices”
  • Now look for the toggle “Bluetooth: On / Off” at the top
  • Turn it On
  1. Pair your devices
  • In “Bluetooth & other devices”, click “Add Bluetooth or other device”
  • Choose “Bluetooth”
  • Put your headphones or mouse in pairing mode
  • Wait for it to show up, click it, finish pairing
  1. If the icon in the tray is missing
  • In the same Bluetooth page, scroll down
  • Click “More Bluetooth options”
  • On Options tab, check “Show the Bluetooth icon in the notification area”
  • Click OK
  1. Check if Bluetooth service is disabled
  • Press Windows key + R
  • Type services.msc then press Enter
  • Find “Bluetooth Support Service”
  • Double click it
  • Set Startup type to “Automatic”
  • Click Start if Service status is Stopped
  • Click OK, then reboot

If after all that there is still no Bluetooth section in Device Manager, no unknown devices with yellow marks, and no driver on the vendor site, your PC might need a USB Bluetooth dongle. They are cheap and work fine for headphones and mice.

Couple extra angles to try that build on what @viajantedoceu already laid out, without rehashing all their steps.

  1. Check for a physical Bluetooth / airplane / wireless switch
    Some laptops have:
  • A function key combo like Fn + F2 / F3 / F12 with a wireless icon
  • A side switch that cuts power to radios
    If that’s off, Windows sometimes hides the Bluetooth toggle entirely.
  1. Verify Airplane mode isn’t being weird
  • Win + A to open Action Center
  • If “Airplane mode” is on, turn it off
  • If it flickers back on by itself, you may have a vendor “radio control” app forcing it. Look in the system tray or uninstall any OEM “Wireless Console / Radio Manager” type tools and reboot.
  1. Check if Windows thinks Bluetooth is blocked by policy
  • Press Win + R, type gpedit.msc, Enter
  • Go to:
    Computer Configuration > Administrative Templates > Network > Bluetooth
  • Make sure there is nothing like “Turn off the Bluetooth radio” set to Enabled
    (If you’re on Home edition you may not have gpedit; skip this in that case.)
  1. Confirm it isn’t being disabled in Power Management
    Even if the adapter looks fine:
  • In Device Manager, right click the Bluetooth adapter > Properties
  • Power Management tab
  • Uncheck “Allow the computer to turn off this device to save power”
  • Same thing for your main Wi‑Fi adapter if Bluetooth is combined with it
  • Reboot and see if the toggle comes back.
  1. Reset the “radio” stack with some commands
    Open Command Prompt as admin and run, one by one:
  • net stop bthserv
  • net start bthserv
    Then restart the PC.
    You can also reset network / radios more broadly:
  • netsh winsock reset
  • netsh int ip reset
    Reboot afterward. Sometimes this kicks a ghost Bluetooth device back into life.
  1. Check for “Hidden devices” in Device Manager
    Sometimes the adapter is there but ghosted.
  • Device Manager
  • View > Show hidden devices
  • Expand Bluetooth and Network adapters
    If you see a greyed Bluetooth device, right click > Uninstall on all of them, then reboot. Windows often reloads it properly as a fresh device.
  1. Look in BIOS / UEFI
    This one is ignored a lot:
  • Reboot, go into BIOS / UEFI (usually F2, Del, Esc depending on brand)
  • Look for something like “Onboard Bluetooth,” “Wireless,” “WLAN / BT,” etc.
  • Make sure it’s Enabled
    Save and exit. If the BIOS has Bluetooth disabled, Windows will never show a toggle, no matter what driver you install.
  1. If you use a USB Bluetooth dongle, test ports and conflicts
    If it’s a dongle:
  • Plug it into a different USB port, preferably on the back if it’s a desktop
  • Avoid USB hubs first
  • In Device Manager, check under “Universal Serial Bus controllers” for any yellow exclamation marks after you plug it in
  • If it shows up as an “Unknown USB Device,” uninstall that and then install the dongle’s driver manually from the manufacturer.

If after all this you still have:

  • No Bluetooth category at all in Device Manager
  • No unknown devices with yellow triangles
  • Nothing Bluetooth in BIOS
    Then realistically the hardware might be dead or never existed on that machine, and a cheap USB Bluetooth dongle is the least painful way forward. I know that sounds like a lazy answer, but at some point you’re just wrestling with a ghost device that isn’t there anymore.

Couple more angles that piggyback on what @viajantedoceu already covered, but focused on cases where Bluetooth completely vanishes from Windows 10.

1. Make sure the device actually shipped with Bluetooth
Happens a lot with desktops and some budget laptops:

  • Google your exact model + “specs”
  • Check under Connectivity for Bluetooth
  • If the spec sheet only lists Wi‑Fi (802.11ac / ax etc.) with no Bluetooth, Windows will never show a toggle because there is no radio

In that case, the cleanest fix is to add a USB Bluetooth adapter instead of chasing ghosts.

2. Use msinfo32 to confirm hardware presence
This is a quick sanity check:

  1. Press Win + R
  2. Type msinfo32 and hit Enter
  3. Go to Components > Network

Look for a Bluetooth entry.

  • If you see nothing Bluetooth related, again that suggests missing or dead hardware.
  • If it shows up here but not in Device Manager, you are almost certainly looking at a driver or service issue.

3. Check the “Bluetooth Support Service” startup type
I do slightly disagree with just restarting the service without checking its startup behavior. Sometimes Windows sets it to Manual or Disabled and it never starts on boot.

  1. Press Win + R, type services.msc, Enter
  2. Find Bluetooth Support Service
  3. Double click it
  4. Set Startup type to Automatic
  5. Click Start if it is stopped
  6. Apply, OK, then reboot and see if the toggle comes back under Settings > Devices

If that service refuses to start and throws an error, note the exact error code because that points to missing drivers or corrupted system files.

4. Run a targeted Bluetooth troubleshooter (the “hidden” one)
Windows 10 sometimes hides it in the old Control Panel.

  1. Press Win + R, type control, Enter
  2. In the search box, type “troubleshooting”
  3. Open Troubleshooting > View all
  4. Run Bluetooth
  5. Let it detect / repair and then reboot

It is basic, but I have seen it flip the correct registry flags back when the toggle was missing.

5. Use System File Checker & DISM for deeper corruption
If your Bluetooth used to work and disappeared after an update, corrupted system files are possible:

  1. Open Command Prompt as administrator
  2. Run:
    • sfc /scannow
  3. After that finishes, run:
    • DISM /Online /Cleanup-Image /RestoreHealth
  4. Reboot

If SFC or DISM report that corruption was fixed and Bluetooth suddenly shows again, you know it was not a hardware issue.

6. For USB adapters: avoid generic “no-name” dongles
If your PC never had Bluetooth or the internal module is dead, a USB dongle is usually the fastest path. Since you mentioned Windows 10, look for one explicitly supporting Windows 10 without needing extra software.

Pros of using a dedicated USB Bluetooth adapter like the typical “How To Turn On Bluetooth Windows 10” type product people recommend in guides:

  • Often plug and play on Windows 10
  • Bypasses flaky or dead internal hardware
  • Lets you move it to another machine easily
  • Good ones handle multiple devices at once (headphones, mouse, keyboard)

Cons:

  • Occupies a USB port permanently
  • Cheap models may have weak range or audio stutters
  • Some older adapters only support Bluetooth 4.0 and may have issues with low energy accessories
  • You might need to uninstall old OEM Bluetooth drivers to avoid conflicts

If you go this route, plug it in, reboot, then check:
Settings > Devices > Bluetooth & other devices
The toggle should appear as long as Windows detects the dongle.

7. When nothing works: clean driver wipe and reinstall
Different from just updating drivers:

  1. In Device Manager, enable “Show hidden devices”
  2. Under Bluetooth, uninstall every Bluetooth entry and tick “Delete the driver software for this device” when available
  3. Under Network adapters, remove any adapter that clearly has Bluetooth in its name
  4. Reboot
  5. Install the latest Bluetooth driver from your PC or motherboard manufacturer
  6. Reboot again and recheck Settings

@viajantedoceu already covered a lot of the core checks like BIOS and hidden devices. Where I would be more blunt: if you have done all of the following

  • No Bluetooth in Device Manager (even with hidden devices shown)
  • No unknown devices with a yellow exclamation mark
  • No Bluetooth listed in msinfo32
  • No Bluetooth option in BIOS / UEFI

then the odds are very high that the machine either never had Bluetooth or the module is physically gone. At that point, spending more time fighting Windows usually costs more than dropping in a small USB adapter and just moving on.
