That leads me to take other measures, like restarting the bluetooth services in Windows. Often times I've been able to recover normal functionality by resetting the bluetooth adapter. I have also ran a sfc /scannow on my Windows10 before installing the Intel drivers - which found some corruptions and it said it fixed them.Sometimes the bluetooth on my laptop fails to connect properly (either not at all, or sometimes with terrible quality) to a pair of stereo headphones. Meanwhile, I have tried uninstalling my current Wi-Fi driver, reinstalling them with the Have Disk section - I remember I had drivers installed from Windows Update before I installed these Intel drivers - so I selected Intel AC 8640 (Microsoft) from the list that populates if you try to add a Legacy Hardware from Device Manager and select Network Adapters from the next popup. Does that have anything to do with Bluetooth by any chance? I do have an Unknown USB Device (Device Descriptor Failed) showing up under Universal Serial Bus controllers section of the Device Manager. So now I have no Bluetooth, can someone help? So, I uninstalled the device, thinking that a restart of the Windows will reinstall the drivers.

Toggled 'Show Hidden Devices' and voilà, Bluetooth was showing but dimmed out, like a disabled device appears. I tried to look for them in Device Manager, couldn't find them. However, I noticed that Bluetooth was off. Now, I have the latest drivers installed from the Intel website version: 20.70.21.2. To permanently fix the problem, I tried to update the AC8640 drivers from the Intel website. It used to prompt me to restart the machine which was undesirable. Recently, it was giving me additional problems while disabling and reenabling. So I had to disable the adapter and re-enable it. The problem started when I noticed that Wi-Fi was getting disabled after Windows would wake up from Sleep Mode. I have a Samsung Spin 7 with Windows 10 Pro (updated to 20H1).
