Bluetooth disappeared from Windows

A vanished Bluetooth toggle usually means the Bluetooth radio dropped off the system: a driver crash, a power-management quirk, or an update that broke the radio module. A full shutdown plus driver work brings it back in most cases.

Why this happens

  • The Bluetooth driver failed or was replaced during a Windows update.
  • Fast Startup left the radio module in a stuck state.
  • The module is disabled in Device Manager or UEFI/BIOS.
  • On laptops the Bluetooth radio is part of the Wi-Fi card - Wi-Fi driver problems take Bluetooth down with them.

Quick checks first

1Full shutdown instead of restart

Hold Shift while clicking Shut down (bypasses Fast Startup), wait 10 seconds, power on. Stuck radio modules often come back after a true cold boot.

2Device Manager with hidden devices

Win+X → Device Manager → View → Show hidden devices. Look for a Bluetooth section, or unknown devices under “Other devices”. A greyed-out entry means the module isn't currently detected.

3Bluetooth support service

Win+R → services.msc → “Bluetooth Support Service” → make sure it's Running with Automatic startup.

4Did it break after a Windows Update?

Settings → Windows Update → Update history. If a driver update landed right before Bluetooth vanished, the update likely replaced the radio's driver.

If Bluetooth is still gone after these checks, the next step is to identify the exact radio module and check its driver - even a module with no name carries a Hardware ID that identifies it.

Drivers most often behind this problem

Fixing it manually

Reinstall the Bluetooth driver

  1. In Device Manager, find the Bluetooth radio (often named after the Wi-Fi chip: Intel Wireless Bluetooth, Realtek Bluetooth Adapter).
  2. Properties → Details → Hardware Ids - Bluetooth radios typically show USB\VID_xxxx&PID_xxxx.
  3. Search that ID in our database, download the driver from the official source, create a restore point and install it.

If Bluetooth is part of the Wi-Fi card

  1. Update or reinstall the Wi-Fi driver first - combined cards (Intel AX-series, Realtek) ship Bluetooth and WLAN in one package.
  2. Reboot fully after installing, then check the Bluetooth section in Settings.

Know the exact device model?

Search the Bluetooth driver database by module name, computer model or Hardware ID. Review matching Windows versions and available driver releases.

Bluetooth radios show up under USB with VID/PID identifiers (e.g. USB\VID_8087&PID_0026 for many Intel modules). In Device Manager: Bluetooth → radio device → Properties → Details → Hardware Ids.

Frequently asked questions

▸Why does Bluetooth vanish after sleep or hibernation?

Power management can fail to wake the radio. In Device Manager → Bluetooth radio → Properties → Power Management, uncheck “Allow the computer to turn off this device to save power”, then do a full shutdown once.

▸I don't know which Bluetooth module is inside. Is that a problem?

No - even when Windows shows the module only as an unknown device, it still carries a Hardware ID. Copy it from Device Manager (Properties → Details → Hardware Ids) and search it in the database: the ID identifies the module and its matching driver without you knowing the name.
