    Ok after days of trying different drivers I found what works do not use the Microsoft update optional updates Ralink driver use the Mediatek 2.3.1.0 04/24/2015 driver look in device manager for hidden devices un install the device then scan for hardware changes if it doesn't instantly work and install the Mediatek driver, but installs the Ralink driver un install it again and check the delete driver check box then scan hardware for changes it should now work if not check for optional updates under advanced options, under windows update, you should see the Mediatek optional update install it then restart under recovery/ advanced startup/ choose disable signature enforcement F7/ then repeat the above steps un install driver then scan hardware for changes it should now work

    Where did you get mediatek driver?
    And there is no issue with USB driver but with PCIe driver, as "rtbth.sys" is using now revoked signature.

    I think I got the correct driver from Lenovo website do a Google search and look for Lenovo link in description The Dell driver does not work also when you install that driver package it will ask to delete drivers and restart once it restarts the driver package will open but now instead of continuing installing go into windows update and look for optional updates let those install and then uninstall the ralink driver in device manager and select delete the files, then scan hardware for changes in control panel and it should work now you may need to restart for Bluetooth to function properly Make sure before you restart you always restart in advance mode disable hardware signature enforcement let me know if you need help or if you got it to work this is literally the only way I was able to get it to work and now it works flawlessly and I don't need to restart and disable driver signature enforcement only during the install procedure
