Bluetooth Missing in Windows 11 and 10? Every Fix

When Bluetooth goes missing from Windows 11 or 10 — the toggle vanishes from Settings, the icon is gone from the taskbar, Device Manager shows no Bluetooth category at all — the fix that works most often is not a driver download. It is this: open Device Manager, click View → Show hidden devices, look under Bluetooth (or Other devices) for a grayed-out adapter, right-click it, choose Uninstall device, and restart. Windows rebuilds the adapter from scratch on the way back up, and in the majority of "Bluetooth completely missing" cases that is the whole repair. But before you start clicking, one fact changes what you should try first: on almost every laptop, Bluetooth and Wi-Fi are the same physical chip. If Wi-Fi is working, the radio is alive and this is a software problem you can fix in ten minutes; if Wi-Fi is also gone, it is the card, a loose antenna, or a BIOS switch, and no driver will bring it back. This guide sorts the problem by what you can see — missing toggle, missing icon, missing from Device Manager, missing after an update, missing after sleep — and walks every fix in the order that finds the cause fastest, on both Windows versions, plus the checks IT departments run before replacing a card.

"Bluetooth is missing" means five different things — find yours first

My friend Ethan, who fixes more laptops for neighbors than he would like, starts every Bluetooth call with the same question: missing from where? Because Windows shows Bluetooth in five places, and which ones have gone dark tells you where the fault is before you touch anything. Check each of these and note what you see.

The pattern to remember: missing from Settings but present (even grayed) in Device Manager is software, and the fixes below will almost certainly work. Missing from Device Manager even with hidden devices shown, and Wi-Fi also dead, is hardware or firmware, and you should skip to the BIOS and hardware sections rather than reinstalling drivers for an hour. The rest of this guide is ordered from most likely to least, so if you are not sure, simply start at the top.

The 30-second checks that solve a surprising share of cases

1. Airplane mode. Press Win + A. If the Airplane tile is lit, click it off. Airplane mode kills Bluetooth and removes its toggle from Settings on some builds, which reads exactly like "Bluetooth missing." Also check Settings → Network & internet → Airplane mode → Wireless devices: Bluetooth can be switched off there independently.
2. The physical radio key. Many laptops have an Fn-key (an antenna or airplane icon, often F2, F3, or F12) or a side switch that disables all radios at the firmware level. Press it once and wait five seconds. If Wi-Fi comes back too, that was it.
3. Is Wi-Fi working? If Wi-Fi is fine, the combined radio chip is powered and this is software. If Wi-Fi is also gone, jump to the BIOS section; you are probably not looking at a driver problem.
4. Plain restart — not Shut down. Windows’ Fast Startup means "Shut down" does not fully reset hardware; Restart does. A Bluetooth radio that stopped responding after sleep often needs exactly this and nothing more.
5. Windows’ own troubleshooter. Windows 11: Settings → System → Troubleshoot → Other troubleshooters → Bluetooth → Run (newer builds hand this to the Get Help app). Windows 10: Settings → Update & Security → Troubleshoot → Additional troubleshooters → Bluetooth. It restarts the service and re-enables the adapter, which fixes the easy cases and costs nothing.

Bluetooth missing from Device Manager: the hidden-devices fix, step by step

This is the fix at the top of the page, in full. It works because a Bluetooth adapter that has failed to start — after a driver update, a Windows update, a bad resume from sleep — is usually still known to Windows; it is just hidden because it is not currently running. Uninstalling that ghost forces Windows to detect the hardware fresh and reinstall a clean driver at the next boot.

1. Right-click Start → Device Manager.
2. Menu View → Show hidden devices. Grayed-out entries now appear throughout the tree.
3. Look for a Bluetooth category. Expand it. You are looking for the adapter itself — something like Intel(R) Wireless Bluetooth(R), Realtek Bluetooth Adapter, MediaTek Bluetooth Adapter, Qualcomm Bluetooth, or, on a Surface, Marvell AVASTAR Bluetooth Radio Adapter. Ignore entries named Microsoft Bluetooth Enumerator and Microsoft Bluetooth LE Enumerator; those are Windows components that exist only when the adapter works.
4. No Bluetooth category? Check Other devices for an Unknown device or anything with a yellow triangle, and Network adapters for your Wi-Fi card with a warning icon. A wireless card that is half-working shows up this way.
5. Right-click the adapter (grayed or not) → Uninstall device. If a checkbox offers Attempt to remove the driver for this device (Windows 11) or Delete the driver software for this device (10), leave it unchecked the first time; you want Windows to reuse the known-good driver. Confirm.
6. Menu Action → Scan for hardware changes. If Bluetooth reappears un-grayed, you are done; check Settings. If not, Restart the PC (a real restart).
7. After the restart, open Settings → Bluetooth & devices. The toggle should be back. If the adapter came back with a yellow triangle instead, note the error code in its Properties → General tab and see the error-code table further down.

If the first pass did not work, repeat steps 5–6 with the remove the driver box checked, then install the maker’s driver (next section) before restarting. That two-pass approach — clean reinstall of the existing driver first, full driver replacement second — resolves the large majority of "Bluetooth missing after update" cases without touching anything else.

The Bluetooth Support Service: the switch that hides the toggle

Windows runs Bluetooth through a background service, and when the service is stopped — by a "debloat" script, an optimizer app, a startup-manager that disabled it as "unnecessary," or simply a crash — the toggle disappears from Settings even though the adapter is perfectly healthy in Device Manager. This is the single most common cause of "Bluetooth toggle missing but Device Manager looks fine."

1. Press Win + R, type services.msc, Enter.
2. Find Bluetooth Support Service (bthserv). Double-click it.
3. Set Startup type to Automatic (not Manual — Manual is the Windows default and works, but Automatic is more robust on machines where something keeps stopping it). Click Start, then OK.
4. Do the same for Bluetooth User Support Service (there is one per signed-in user, with a suffix like _4a2f1) and, on Windows 10, Bluetooth Audio Gateway Service if you use headphones.
5. Sign out and back in. The toggle returns without a restart in most cases.

From an administrator PowerShell, the same thing in two lines: Set-Service bthserv -StartupType Automatic; Start-Service bthserv. If Start fails with "the dependency service or group failed to start," the adapter is not present — go back to Device Manager; the service cannot run with nothing to support.

Bluetooth missing after a Windows update: why, and the two fixes

Cumulative updates and, above all, feature updates (Windows 11 24H2 to 25H2, the yearly kind) replace the Bluetooth stack’s system files and sometimes swap your manufacturer’s driver for a generic Microsoft one that does not know your chip’s power-management quirks. The result is an adapter that appears for a boot or two and then vanishes, or that never comes back after the first sleep. Two fixes, in order. First, roll the driver back: Device Manager → Bluetooth → adapter → Properties → Driver tab → Roll Back Driver. If the button is available, it restores the driver that worked before the update; restart. Second, if Roll Back is grayed out (no previous driver kept), install the maker’s current driver — not through Windows Update, which will hand you the same generic one, but from the chip vendor or your laptop maker. Intel’s Bluetooth driver comes from Intel’s download center or the Intel Driver & Support Assistant; Realtek and MediaTek ship theirs through the laptop maker (Dell SupportAssist, HP Support Assistant, Lenovo Vantage, ASUS MyASUS, Acer Care Center). Install, restart, and then — this matters — in Device Manager, on the adapter’s Power Management tab, uncheck Allow the computer to turn off this device to save power, which stops Windows from switching the radio off during sleep and forgetting to switch it back on.

If it broke within the last ten days after a feature update and nothing above helps, Settings → System → Recovery → Go back returns you to the previous version with Bluetooth intact, and you can pause updates for a few weeks until the vendor ships a compatible driver. For a monthly cumulative update, Settings → Windows Update → Update history → Uninstall updates removes just that KB. Our companion post on Bluetooth not working after a Windows update goes deeper on the update-specific side, including what to do when the adapter is present but pairing fails.

Jake’s laptop: three hours of drivers for a problem that was in the BIOS

Jake’s laptop lost Bluetooth on a Tuesday. No toggle in Settings, no icon in the tray, nothing in Device Manager. He did what the internet told him: downloaded Intel’s Bluetooth driver (his Wi-Fi card is an Intel AX211), installed it, got an error that no device was found, downloaded an older version, same error, ran the troubleshooter, restarted eleven times, and by the third hour had begun reading about replacing the card. Then he called Ethan, who asked the question: is Wi-Fi working? It was not. Jake had been using the laptop docked, on Ethernet, and had not noticed. Wi-Fi and Bluetooth share the AX211 module, and both were gone — which meant no driver on Earth would help, because Windows could not see the card at all.

The cause turned out to be almost embarrassingly small. A firmware update had been applied by the laptop maker’s support app, and it reset one BIOS setting to its default: Wireless LAN was enabled, Bluetooth was set to Disabled under Onboard Devices, and a second option, Wireless device enable, was Off. Two toggles in a setup screen he had never opened. He enabled both, saved, and Windows found the adapter before the desktop had finished loading. Total fix time: four minutes. The lesson he now repeats to everyone: when a radio is completely missing — not broken, not erroring, but absent — and its sibling radio is missing too, check the BIOS before you download a single driver.

Bluetooth completely missing: the BIOS/UEFI check

1. Settings → System → Recovery → Advanced startup → Restart now → Troubleshoot → Advanced options → UEFI Firmware Settings → Restart. (Or tap the maker’s key at power-on: F2 on Dell/ASUS/Acer, F10 on HP, F1 or Fn+F2 on Lenovo, Del on most desktops.)
2. Find the devices page: Advanced, Onboard Devices, System Configuration, Wireless, or Power & Performance depending on the maker.
3. Look for Bluetooth, Wireless Device Enable, WLAN/Bluetooth, or Onboard Wireless. Set each to Enabled / On. On some Dell and HP models there are two separate switches; both must be on.
4. While you are there: if the BIOS lists the wireless card by name (e.g. "Intel Wireless-AC 9560") the hardware is alive; if the wireless section is empty or missing, the card is not being detected at the firmware level — the hardware section below applies.
5. Save and exit (usually F10). Windows detects the adapter on boot and installs a driver automatically.

A related firmware fix for laptops where Bluetooth disappears only sometimes: a full power drain. Shut down, unplug the charger, hold the power button for 30 seconds (on models with a removable battery, take it out first; on sealed models, some makers provide a pinhole reset), then boot. It clears a stuck state in the wireless module’s own controller that neither Windows nor a restart touches. Ethan does this before any driver work on a machine that has been in sleep for days.

Installing the right Bluetooth driver (and why Windows Update’s is often the wrong one)

First, find out which chip you have; guessing leads to installing Intel drivers on a Realtek card, which does nothing except waste an afternoon. In Device Manager, under Network adapters, read the Wi-Fi card’s name — on nearly every laptop the Bluetooth radio is the same module, so an Intel Wi-Fi 6E AX211 means Intel Bluetooth, a Realtek 8852BE means Realtek Bluetooth, a MediaTek MT7922 means MediaTek. If the Wi-Fi card is also missing, the BIOS and hardware sections come first.

Install order that avoids the common mess: uninstall the existing Bluetooth adapter in Device Manager with remove the driver checked, restart, install the new package, restart again, then go into the adapter’s Power Management tab and turn off power saving. Do not run two makers’ packages on top of each other, and do not use third-party "driver updater" apps — our guide to uninstalling drivers cleanly explains why they make this specific problem worse.

Bluetooth icon missing from the taskbar, or the tile gone from Quick Settings

If Bluetooth works — devices connect — but the icon or tile is gone, nothing is broken; a display setting changed. Windows 11 tray icon: Settings → Bluetooth & devices → Devices → scroll to More Bluetooth settings → Options tab → check Show the Bluetooth icon in the notification area. Then, because Windows 11 hides tray icons by default, Settings → Personalization → Taskbar → Other system tray icons → turn Bluetooth on, or drag it out of the overflow chevron. Windows 11 Quick Settings tile: Win + A → pencil icon (Edit quick settings) → Add → Bluetooth. Windows 10: Settings → Devices → Bluetooth & other devices → More Bluetooth options → Options → Show the Bluetooth icon; and for the Action Center tile, Settings → System → Notifications & actions → Edit your quick actions → Add → Bluetooth. If the icon setting is grayed out, Bluetooth is off or absent — back to the sections above.

Device Manager error codes on the Bluetooth adapter, decoded

Is the Bluetooth hardware actually dead? How to tell, and the $10 answer

Three signs together point at hardware: Wi-Fi is gone too; the BIOS wireless section is empty or does not list the card; and a full power drain changes nothing. On a desktop, or a laptop with an accessible M.2 slot (many have a small door), the card can be reseated: power off, unplug, ground yourself, remove the screw, pull the card, push it firmly back, and re-attach the two tiny antenna leads (they pop on like press-studs; a detached one causes exactly the intermittent-then-gone behavior). The same slot accepts a replacement card — an Intel AX210 or AX211 costs little and brings Wi-Fi 6E and Bluetooth 5.3 to most laptops made after 2018, though a few makers whitelist cards in the BIOS, so check a forum for your model first. If opening the machine is not an option, a USB Bluetooth adapter restores Bluetooth in thirty seconds for about the price of lunch. Plug it in, and Windows installs it as a second adapter; disable the dead internal one in Device Manager so the two do not fight over the same devices. That is not a defeat; it is the same chip in a different housing, and it is what Ethan keeps in his bag.

Bluetooth disappears after sleep and comes back after a restart: the power-saving fix

If the pattern is "gone after the lid was closed, fine after a restart," Windows is turning the radio off to save power and the driver is not waking it. Three settings, all cheap. One: Device Manager → Bluetooth adapter → Properties → Power Management → uncheck Allow the computer to turn off this device to save power. Two: the same on every USB Root Hub and Generic USB Hub under Universal Serial Bus controllers, because internal Bluetooth radios are usually wired to the USB bus even when soldered to the board. Three: Control Panel → Power Options → Change plan settings → Change advanced power settings → Bluetooth (if listed) and USB settings → USB selective suspend → Disabled on battery and plugged in. If all three are set and it still happens, the current maker’s driver almost certainly fixes it — the "missing after sleep" bug was a well-known early-Windows-11 issue on MediaTek and some Intel cards, and vendors shipped corrected drivers through 2024.

A device stuck on "Remove device" or "Removing…" forever: the related fix

A close cousin of the missing adapter, and one this page now covers because it used to have its own short entry: you click Remove device on a paired headset or mouse and it sits at "Removing…" indefinitely, or reappears after a restart. The cause is the same stalled service. Fix it in this order: open services.msc and Restart the Bluetooth Support Service; try the removal again from Settings → Bluetooth & devices → Devices (the newer page) rather than the old Control Panel Devices and Printers, because the two do not always agree; if it still sticks, open Device Manager with hidden devices shown, expand Bluetooth, and uninstall the stubborn device’s own entry (it appears by name, often more than once), then restart. For a device that has already been forgotten by the headset or mouse itself, hold its pairing button until it enters pairing mode and pair fresh; Windows replaces the stale record rather than duplicating it.

Does my PC even have Bluetooth? How to check before you chase a ghost

Not every PC does. Most desktops built before 2020, many budget desktops still, and a few business machines ship without it, and their owners can spend an evening "fixing" an adapter that was never there. Quick tests: in Device Manager with hidden devices shown, look for any Bluetooth category or a wireless card whose name includes Bluetooth; check the Network adapters list for a Wi-Fi card (a card with Wi-Fi almost always has Bluetooth, a machine with only an Ethernet adapter almost never does); look up the model on the maker’s spec page; or open a Command Prompt and run Get-PnpDevice -Class Bluetooth in PowerShell — an empty result plus no Wi-Fi card means there is no radio to fix. The answer for a desktop without Bluetooth is the USB adapter in the hardware section, and it takes less time to install than reading this paragraph did.

For IT admins: the checks before you swap a card, and the policies that hide Bluetooth on purpose

When a user reports Bluetooth missing on a managed device, rule out policy before hardware. Intune’s Connectivity/AllowBluetooth CSP, the Group Policy Computer Configuration → Administrative Templates → Windows Components → Bluetooth settings, and older Device Installation Restrictions that block a device class by GUID (Bluetooth’s is {e0cbf06c-cd8b-4647-bb8a-263b43f0f974}) all produce a machine where the adapter is present but the toggle is absent or grayed, and the user’s uninstall-and-restart will never fix it. gpresult /h or the Intune device’s policy report settles it in a minute. Second, check whether the fleet’s driver package changed: a Windows Update driver ring or a Dell/HP/Lenovo commercial driver pack that introduced a version with a known sleep regression is the usual explanation for a sudden cluster of tickets, and pinning the previous version through your update tooling beats touching each laptop. Third, for the genuinely-absent cases, pnputil /enum-devices /class Bluetooth and pnputil /enum-drivers in a remote shell tell you whether the device is enumerated and which driver store entries exist; pnputil /remove-device and pnputil /scan-devices perform the uninstall-and-rescan remotely without a desktop session; and the Event Viewer channel Microsoft-Windows-Kernel-PnP/Configuration shows the device’s arrival and removal events with timestamps, which is how you prove "it disappears at resume" before you order a part. Only when the device is absent from PnP enumeration and from firmware do you swap the M.2 card — and a USB adapter is a legitimate interim for a user who needs a headset today.

FAQ — Bluetooth missing in Windows, answered straight

Why is Bluetooth missing from Windows 11?

Because Windows currently sees no working Bluetooth adapter: airplane mode, a stopped Bluetooth Support Service, a driver broken by an update, a radio that did not wake from sleep, or a BIOS setting. Check them in that order; the Device Manager uninstall-and-restart fixes most.

How do I fix Bluetooth missing from Device Manager?

View → Show hidden devices; uninstall any grayed Bluetooth adapter or unknown device; Action → Scan for hardware changes; restart. If no adapter appears even hidden, check BIOS wireless settings and whether Wi-Fi is also gone.

Why did Bluetooth disappear after a Windows update?

The update replaced the Bluetooth stack or swapped in a generic driver. Roll Back Driver in Device Manager, or install the chip maker’s current driver, then turn off power saving on the adapter.

The Bluetooth toggle is missing in Settings but Device Manager looks fine — why?

The Bluetooth Support Service is stopped. services.msc → Bluetooth Support Service → Automatic → Start. Sign out and in.

Why is the Bluetooth icon missing from the taskbar?

It is hidden. Bluetooth & devices → More Bluetooth settings → Show the Bluetooth icon; then Personalization → Taskbar → Other system tray icons → Bluetooth on.

Bluetooth is completely missing from my laptop — is it broken?

Check Wi-Fi. If Wi-Fi works, the shared chip is fine and it is software. If Wi-Fi is also gone, check the BIOS wireless/Bluetooth switches and do a full power drain before assuming hardware.

How do I turn Bluetooth back on in Windows 11?

Win + A → Bluetooth tile, or Settings → Bluetooth & devices → toggle On. If there is no toggle, the adapter is not working — follow the fixes on this page.

How do I turn Bluetooth on in Windows 10?

Settings → Devices → Bluetooth & other devices → toggle On, or the Action Center tile. Same rule: no toggle means no working adapter.

Does my computer have Bluetooth?

If it has a Wi-Fi card, almost certainly yes; if it has only Ethernet, almost certainly no. PowerShell Get-PnpDevice -Class Bluetooth lists any adapter Windows has ever seen.

How do I reinstall the Bluetooth driver in Windows 11?

Device Manager → Bluetooth adapter → Uninstall device (check "remove the driver") → restart → install the maker’s package (Intel, or your laptop brand for Realtek/MediaTek) → restart.

Why does Bluetooth disappear after sleep?

Power management turned the radio off and the driver did not wake it. Uncheck "Allow the computer to turn off this device" on the adapter and the USB hubs, disable USB selective suspend, and update the driver.

Why is Bluetooth not showing in Device Manager but Wi-Fi works?

The Bluetooth half of the combo card failed to enumerate. Show hidden devices and uninstall any ghost; reinstall the maker’s Bluetooth driver (it is a separate package from Wi-Fi); check the BIOS has Bluetooth enabled separately.

Can I add Bluetooth to a PC that doesn’t have it?

Yes. A USB Bluetooth adapter works on any Windows 10/11 PC, usually with no driver. Desktops can also take a PCIe or M.2 Wi-Fi/Bluetooth card.

Bluetooth is missing after I reset or reinstalled Windows — why?

Windows did not have an inbox driver for your chip. Install the maker’s driver package; Windows Update sometimes offers it under Optional updates → Driver updates.

What is the Bluetooth Support Service and is it safe to set to Automatic?

It is the Windows service that runs Bluetooth discovery and pairing. Automatic is safe and costs nothing; do not let optimizer apps disable it.

Bluetooth shows Code 10 or Code 43 — what does that mean?

Code 10: the device cannot start (driver/firmware; roll back or reinstall, power-drain). Code 43: the radio crashed (uninstall, restart, disable power saving; recurring after a power drain suggests failing hardware).

Is there a command to fix missing Bluetooth?

Admin PowerShell: Set-Service bthserv -StartupType Automatic; Start-Service bthserv for the service; pnputil /scan-devices to re-detect hardware. There is no single command for a missing adapter.

Why is Bluetooth grayed out or managed by my organization?

A work policy disables Bluetooth or blocks the device class. Only your IT team can change it; the IT section names the policies.

Bluetooth is back but my headphones won’t pair — same problem?

No; that is pairing, not the adapter. Remove the device and re-pair; see our Bluetooth PIN guide and the connected-but-no-sound guide linked below.

Should I use a driver-updater app to fix Bluetooth?

No. They install mismatched or bundled drivers and make this problem worse. Use the chip maker or your laptop maker only.

Where to go next

Revision note. This page began in November 2016 as a short note about Bluetooth vanishing after the Windows 10 Anniversary Update. Rewritten August 29, 2026, for Windows 11 and 10, and it now absorbs the questions from several older, shorter pages on this site — Bluetooth missing from Device Manager, the stuck "Remove device" state, checking whether a PC has Bluetooth at all, and the 1903/1909-era discovery bugs — so one page can answer all of them. Settings paths and the troubleshooter route were checked against Microsoft’s current support pages the same day; chip and driver-source details reflect what ships in laptops sold through 2026. If a menu has moved on your build, tell us through the contact page and we will put it right. And if you are three hours in, like Jake was: stop, check whether Wi-Fi works, and open the BIOS. The fix is usually smaller than the search.
