Hey guys, we have a Dell R12 Alienware desktop PC with latest Windows 11 as of 8/4/23, and the same thing happened to it. I fooled around with it for 3 hours last night trying everything I could think of. Then today I found this thread. I shut it down normally and unplugged from power for 10 minutes, plugged it back, powered on and fixed! It seems to be a power thing whether you have a laptop or a desktop. Thanks a bunch and hope others find this thread!

Bluetooth disappeared (Windows 11)

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!

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
