Fix: Bluetooth Not working in Windows 10 after 21H1 Update

After the recent Windows 10 update of 21H1, some users complained that their Bluetooth devices stopped working.

I was also one of the troubled guys who faced this issue. Common solutions to fix the issue were not useful.

I used Windows default troubleshooter to see the Bluetooth option under Settings > Devices.

But that option disappeared.

Bluetooth is not available on this device in Windows 10

Somebody in the Microsoft forum suggested turning off the “fast start-up” in the power management setting of the Control Panel.

Then they asked to shut down the computer and start it again.

This solution also didn’t work. I also wasted considerable time.

The culprit was that the Bluetooth drivers were not up-to-date. If you find the Bluetooth device in device manager it means recognized by Windows 10.

The driver update using CCleaner helped me to update Bluetooth driver.

Select Start and find Settings (gear icon). Under Devices > Bluetooth & other devices you should see the option. If not there is some issue with Bluetooth driver.

Initial Steps

1. Make sure Bluetooth button turned on your laptop or pc.
2. Generally, old PCs don’t have in-built Bluetooth. Then you need to purchase a Bluetooth adapter.
3. Plug it in into one of the USB slots and make sure the indicator is glowing or working.
