Windows 10: bluetooth service error: the parameter is incorrect

samsung galaxy buds were connected as a headset which meant the audio quality was poor, while searching for a solution, I found one which said to disable 'hands-free telephony' in services. this didn't fix my problem, but now when I try to turn this back on it says 'the paramater is incorrect'. I have spent ages looking for solutions and have removed the device and added it again and tried resetting the earphones. they previously worked fine with my computer and today they firstly didnt work, then later after reconnecting them a couple times, they worked but the sound quality was weird and then in trying to fix that they now dont make sound when connected to my laptop

The parameter is incorrect Bluetooth User Support Service to Auto

Hello,

My Bluetooth was not detecting any devices. I started Bluetooth User Support Service and it seemed to work. My PC said it's discoverable. But the problem is I need to restart my PC for it to work but when I do, it just shuts off again! I tried changing it to Automatic and Automatic Delayed Start but it kept saying The parameter is incorrect.

I can't find any solution right now

Thanks in advance,

Hi jantis,

I have found a possible solution for both of us (I can't test it right now) it's changing the start type in the registry from Manual to Automatic.

Change "Start" from 3 to 2 in the following places:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BluetoothUserService
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BluetoothUserService_33965
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\bthserv

I am not sure it will work but i'll try it soon

Edit: I just saw that you cannot turn on/off Bluetooth, i know how to fix that.

Step 1: Open services.msc
Step 2: Start the following services:

Bluetooth Support Service
Bluetooth Audio Gateway Service
and any other Bluetooth related services.

Then set all of them to automatic.

BTW: I am having a problem setting Bluetooth User Support Service to Automatic, but the registry thing I showed you up in my post might fix it.

OH BOY !!
This is exactly the same problem I am having.
Driver is good, It says Device is working properly.
But,when I go to Services.msc, Bluetooth service Properties, well there is NO way to put that on Automatic Start nor change NT AUTHORITY\LocalService nor put it to my account using my password ....well this is so frustrating to see this message saying

The parameter is incorrect

Btw i read somebody fixing this,error but not on hardware saying he had to find %temp% folder
first and then give more Admin rights or something like that and the error went away for good !

Please TECH GUYS in here HELLLPPPP US !!!

THANKS IN ADVANCED GUYS !!!
