Bluetooth device not found on Windows Update

Solved

Hello,
My Sony VAIO VPC-eh3u1e/bfr5 computer comes with Bluetooth option and I used to be able to exchange files with my tablet or phone. I haven't used Bluetooth for several months and yesterday I realized it no longer works. When I try to transfer files from my computer to my phone, nothing happens. I've tried uninstalling and reinstalling the drivers, but as you can see in screenshot #1, the Bluetooth device is not found on Win Update... In Device Manager, under the "Other devices" category, there are 3 fields labeled "Bluetooth device," and there is an exclamation mark next to each one, as you can also see in the second screenshot. I have uninstalled and reinstalled several times the drivers I downloaded from Sony's official website, but nothing changes... I'm out of ideas, so if you could help me, that would be really great.
Thank you!

    Right-click on the 3 Bluetooth devices
    Uninstall them
    Restart the PC
    Check if there are still alerts in the device manager.

    Hello,
    I followed your instructions and the Bluetooth devices have still reappeared, after the restart in the manager with the same exclamation mark next to it.

    Hello,
    It seems to be working this time, even though there is still an exclamation point in the device manager next to two Bluetooth devices.
    Thank you!

    Disable them
    Restart the PC and see if there are still any alerts in the device manager.

    Yes, at the end of the scan it said "windows found corrupted files and was able to repair them." Do you want me to copy and paste the cbs.log?
