Windows update is one of the most notorious things that you have to run from time to time, but will almost certainly cause troubles every time. That includes suddenly losing Bluetooth functionality and fail to discover, pair or connect your Bluetooth devices such as Bluetooth mouse, keyboard or headset.
The Bluetooth not working issue commonly happens on laptop computers (HP, Dell, Lenovo, Asus, Acer, Toshiba, etc.) that have a built-in Bluetooth adapter. Here’s a few workarounds and troubleshooting on how to fix the Bluetooth not working issue after Windows update in Windows 11/10.
How to fix Bluetooth not working in Windows 11/10
Check if you have properly turned on Bluetooth
I know you might have already checked this multiple times since the problem occurred. It’s best to check it again in the settings as shown below to make sure your Bluetooth adapter does exists and is enabled.
Search for and open Settings via the Start menu. Select Bluetooth & devices. Make sure the Bluetooth toggle is On. For in-depth guide, read: How to Turn On Bluetooth on Windows 11/10.
If the Bluetooth option is visible and is turned on, Windows should be able to discover other Bluetooth devices near your PC. If it’s on and still not being able to detect your Bluetooth mouse, headset or keyboard, you will have to check your device/peripheral instead to see if it’s properly switched on, has a working battery, and is not broken.
You can also try to remove and disconnect the Bluetooth device, then re-discover and pair it again. This is a common workaround for most Bluetooth device that suddenly stops working in Windows 11/10.
If there is no Bluetooth toggle in the Windows settings, try the following workarounds.
Check if you’ve enabled Bluetooth in Device Manager
If you don’t see the Bluetooth toggle in the settings, it most likely means that your Bluetooth adapter driver is either disabled or not correctly installed.
Go to start menu or Cortana. Search for and open Device Manager. Then, go to View on the menu and enable Show hidden devices.
From the list of devices, expand the category called Bluetooth or Bluetooth Radios. Then, right-click on your primary Bluetooth adapter (usually would appear as Intel Wireless Bluetooth adapter, Realtek Bluetooth adapter, Broadcom Bluetooth driver, or Generic Bluetooth adapter, for most laptops), and then click on Enable device.
Check your Bluetooth driver
If your Bluetooth driver has a yellow exclamation mark beside it and cannot be enabled when you right-click it, try to update the Bluetooth driver.
To update the driver, follow the steps as outlined above to open Device Manager to view your Bluetooth adapter. Then, right-click on the problem Bluetooth adapter, and select Update Driver Software.
Alternatively, you can also select Uninstall to uninstall the driver and restart your PC. Doing so will allow Windows 11/10 to automatically search for (from Microsoft’s driver repository) and install the latest Bluetooth driver that matches your Bluetooth adapter.
If the Bluetooth driver isn’t even listed in the Device Manager as if it was missing, it could mean that your Bluetooth adapter is faulty, incorrectly connected, or Windows couldn’t find the driver for your adapter. If that’s the case, try this guide instead – Download Bluetooth Driver for Windows 11/10.
Missing or corrupted Bluetooth drivers are common especially after applying a recent major Windows update due to changes in system files which might cause conflicts and problems in Windows.
Try the Bluetooth troubleshooter
If nothing works to resolve your Bluetooth not working issue, try to run the Bluetooth troubleshooter from the Settings app.

- Press Win+i keys to open Settings. Under System, scroll down and select Troubleshoot. Next, select Other troubleshooters. Then, under Other and next to Bluetooth, click on Run to run the Bluetooth troubleshooter.
