    Bluetooth Support Service appearing with the error Parameter is incorrect


    So I've done everything to try and get my Bluetooth working again. Like doing the registry edits in safe mode etc. Disabling all Microsoft services and entering a safe boot to try and get that to work as well. I have literally had no luck can yall please try and help my issue.

    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.

    The parameter is incorrect Bluetooth User Support Service to Auto

    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 !!!
