How to PERMANENTLY disable Handsfree Telephony for a bluetooth device in Windows 11?

This is what I've been looking for! Thanks a million! 😁

Not sure if this will help, but for me I was able to permanently disable the handsfree part of my bluetooth headphones by disabling the system device entry for it in the Device Manager->System Devices area on my Windows 11 machine. (Note that the system device is different from the driver and represented by a different icon (for me a computer tower and blue pane monitor):

Simply right-click and disable:

I have noticed that this method requires me to have to hit the connect button in Bluetooth & devices -> Devices more often / almost every time I turn my headphones back on, but it has helped me not have to disable the handsfree device every time which I found just a bit more cumbersome. Teams also now picks up the proper device so I don't lose audio.

SOLVED !!!!

NOTE: This will only show under "System Devices" (as pictured) IF you have the headphones connected AND have NOT unchecked handsfree telephony in [ Devices and Printers > Headphone Properties > Services ]

I have been dealing with this for YEARS and THIS IS THE ONLY PERMANENT SOLUTION I have found. Not to mention it is SO easy.

Before this solution, I had a link on my desktop to "Devices and Printers" and had to uncheck "Handsfree Telephony" every time my computer booted for my headphones to work normally while gaming and using discord.

I use Bose Quiet Comfort 35 Wireless Headphone II

So, once again for the search algorithms:

HUGE thanks to @ElectricDrake

To completely disable hands-free for all bluetooth devices, you can open terminal and do the following commands:

reg add HKLM\SYSTEM\ControlSet001\Control\Bluetooth\Audio\Hfp\HandsFree /v Enabled /t REG_DWORD /d 0 /f

reg add HKLM\SYSTEM\ControlSet001\Control\Bluetooth\Audio\Hfp\AudioGateway /v Enabled /t REG_DWORD /d 0 /f

hey i have a problem when i press Devices and printers it opens up settings how do i fix this

go to bluetooth and devices, click view more device, scroll down to more devices and printers, that will take you back to control panel and where you want to go. i don't know why they made you go through settings to do that but they did

Thanks for this @RyokuY! This works also! For those more comfortable with a gui, you can do this with the registry editor too with the same paths as the command prompt. Regedit-> then Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Bluetooth\Audio\Hfp\AudioGateway

Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Bluetooth\Audio\Hfp\HandsFree

Set both Enabled = 0

As always, be very careful when modifying the registry (do a backup first if you feel the need)
