Update: Resolved issue by disconnecting PC from power (unplugging from wall) for 10 minutes and then restarting. Baffling. Bluetooth services disappeared several weeks ago and I've been trying to get it back. Here's what I've found so far: Bluetooth troubleshooter couldn't solve it Restarting Bluetooth Services - I have done this, and have set all to start automatically however BluetoothUserService_5aacd will not allow me to move it from Manual to Automatic, I get a "The parameter is incorrect" error I uninstalled and reinstalled the BT drivers, which did not fix the issue I have uninstalled Intel(R) Wireless Bluetooth(R) within Device Manager, and restarted computer, which reinstalled the Intel BT but did not fix the issue (note: my Device Manager is constantly refreshing/ flashing, unsure if related) Thank you in advance for your help! EDIT: I was able to update BluetoothUserSErvice to start automatically at start up, correcting the "parameter is incorrect error". This did not resolve my bluetooth problem.

It worked for me even with two minutes.

Thank you so much, this just helped me out! I went to device manager, view hidden device, uninstalled bluetooth drivers. Uninstalled some random corrupt usb device. Shutdown. Switched off the PSU. Started up and it worked!

Solved with this: Deactivate and activate the "mysterious usb" (it's the bluetooth) in the device manager. It came back right after I did this.

Bluetooth disappeared (Windows 11)

Hi ADP,

Sharing my experience with the hope that it helps others resolve their bluetooth issue as well. My bluetooth had disappeared suddenly without any cause or reason and it did not come back by reinstalling the device drivers, or resetting the bluetooth services, or by trying a lot of other solutions. Bluetooth had disappeared from Device Manager and replaced with a mystery USB device. Nothing seemed to bring it back.

Eventually what worked is to shut down the laptop completely and disconnect the power cable and kept it shut for about 10 minutes before starting it up again. (make sure it is fully shut down and not sleep and not restarted)

Laptop : Asus zendesk with Windows 11 Pro 21H2 (updated to the latest fixes). Uses Intel Wireless Bluetooth drivers.

The solution is based on the following thread with similar issues for Windows 10. https://answers.microsoft.com/en-us/windows/forum/all/bluetooth-capability-not-detected-windows-10/0db9ce62-eba9-4b85-9e5c-15336f41bfe3?page=2

I confirm this worked for me too. I shut down and unplugged my laptop before going to bed. This morning the Bluetooth icon was on its place again.
