2024-03-30T18:02:03+00:00 The last couple of Windows 11 Updates have wrecked havoc with my Bluetooth connecting to headphones, and losing audio all together on laptop. I have an Acer and haven't had any issues at all until these last couple or so updates.
The only solution I have found is holding down power button on laptop until it turns off, then unplug power cord. Then it all resets back to normal until it disconnects due to inactivity (see below). The Troubleshooter for Bluetooth, and also for Audio issues doesn't work either.
The current issue is that Bluetooth is working fine when I turn on the laptop. But if it disconnects on it's own to my headphones due to inactive sound after a period of time, it will not reconnect to my headphones unless I use the solution. above
This is clearly a Windows Update issue causing this, and is quite annoying to say the least.

2024-02-16T11:51:20+00:00 Can you post a screenshot from device properties with driver information tab?
here you go?
I had to run this installer after disabling driver signature enforcement in advanced startup mode run the setup.exe it will ask to un install then prompt to restart, don't restart from the prompt use advanced startup and disable driver signature enforcement in advanced startup then the installer will open but don't run the installer check for windows updates and install the optional updates under advanced options windows update once windows installs those updates it will install the Ralink driver go to device manager and un install it also select the delete driver check box then scan hardware for changes that will install the Mediatek driver you should now have Bluetooth
