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.
Quick checks first
1. Full 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.
2. Device 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.
3. Bluetooth support service
Win+R → services.msc → “Bluetooth Support Service” → make sure it's Running with Automatic startup.
4. Did 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 - manually, or automatically if the module shows up with no name.
Fixing it manually
Reinstall the Bluetooth driver
- In Device Manager, find the Bluetooth radio (often named after the Wi-Fi chip: Intel Wireless Bluetooth, Realtek Bluetooth Adapter).
- Properties → Details → Hardware Ids - Bluetooth radios typically show USB\VID_xxxx&PID_xxxx.
- 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
- Update or reinstall the Wi-Fi driver first - combined cards (Intel AX-series, Realtek) ship Bluetooth and WLAN in one package.
- 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.
Try for example: Intel Wireless Bluetooth · read the Hardware ID guide · or browse the driver category
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?
Not for the automatic path - the free scan identifies the radio module even when Windows shows it only as an unknown device, and checks its driver on its own. Knowing the module name is only required for the manual search.
