Windows 10: Bluetooth no turn on/off option and has yellow warning sign on device manager

Please help i tried fixing it by updating, reinstalling, disabling and enabling nothing seems to work. I also tried setting it automatic on start up still no luck and regeditor

:)

 

I don't have any bluetooth devices but windows turned it on!!

1. I have no bluetooth devices in devices manager.
2,3,4. they all turned off before.

reboot or shutdown doesn't solved it.
i have USB wireless Mouse/Keyborad. i plug it out and use PS/2 but nothing.
i used DISM to repair image.

i tried everything but its not make any changes and windows still showing Bluetooth turned on.
a few days ago it was not even showing Bluetooth in Action Center but i don't understand what happened, no devices added or changed in my PC, no software Installed or Uninstalled, not a single Settings Changed in Windows or BIOS!!!

 

I don't have any bluetooth devices but windows turned it on!!


Then if they are still on, try some of these steps listed below, Not all of these steps may not apply, but, step #2 and #4 should help. I have all 4 steps on myself.

1 Go to Device manager and DISABLE Bluetooth, Do Not remove!
2 Turn USB suspend off
3 Set Hard Drive or SSD to Never
4 Turn Link State Power Management off
Settings 2 thur 4 can be found in your Power Management Settings.
Then click on "Change settings that are currently unavailable"
Then Reboot your Computer. This does work, may come back if you shut OFF your computer,then turn it back on, if it does, just a reboot will turn it off again.
