After the recent Windows 10 update of 21H1, some users complained that theirBluetooth 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 underSettings > Devices.
Then they asked to shut down the computer and start it again.
This solution also didnt work.
I also wasted considerable time.
I successfully saw the Bluetooth option in controls and connected Bluetooth speakers without any hindrance.
If you find the Bluetooth rig in rig manager it means recognized by Windows 10.
The driver update using CCleaner helped me to update Bluetooth driver.
SelectStartand findSettings(gear icon).
UnderDevices > Bluetooth & other devicesyou should see the option.
If not there is some issue with Bluetooth driver.
Your Bluetooth option should be available in prefs again.
Conclusion
My old Bluetooth adapter release date was 2006 and updated to the new version of 2013.
CCleaner is very good about finding the older gear drivers and updating them to the new ones.
