Frequently Asked Questions
Why did Bluetooth stop working after Windows update?
Windows updates can: (1) Replace the Bluetooth driver with an incompatible generic version, (2) Disable the Bluetooth adapter, (3) Remove paired devices, (4) Change Bluetooth service settings, (5) Introduce bugs in the Bluetooth stack. Intel and Realtek Bluetooth adapters are most commonly affected.
Bluetooth option disappeared from Settings — how to fix?
Open Device Manager → View → Show hidden devices. Look for Bluetooth adapters. If present but disabled, right-click → Enable. If missing, the driver was removed by the update — restart first, then download the Bluetooth driver from your laptop manufacturer's website.
Bluetooth headphones connect but no audio after update?
This is a common audio routing issue: (1) Right-click speaker icon → Sound settings, (2) Set output to your Bluetooth headphones, (3) If listed as 'Hands-Free' instead of 'Stereo,' remove the device and re-pair it, (4) Check that Bluetooth Audio Gateway service is running in services.msc.
How do I roll back the Bluetooth driver?
Device Manager → Bluetooth → right-click your adapter → Properties → Driver tab → Roll Back Driver. If grayed out, Windows doesn't have a previous driver. In that case, download the previous driver version from your manufacturer's support page.
Can I get Bluetooth working without rolling back the update?
Yes, in most cases. Try: (1) Restart the Bluetooth Support Service (services.msc), (2) Remove and re-pair all devices, (3) Reinstall the Bluetooth driver, (4) Run the Bluetooth troubleshooter, (5) Reset Bluetooth via Settings → Bluetooth → Remove all devices → restart. Rolling back the update is a last resort.
