Windows 10: My Bluetooth Disappeared

I have been using a Bluetooth headset for a while now and today I turned on my PC and the headset did not connect. I went to Bluetooth troubleshooting and when I ran it I got the message "Device does not have Bluetooth." I'm beyond confused because I have been using Bluetooth this whole time and now can not seem to find any trace of Bluetooth or Bluetooth devices I had connected on my computer. Help me.

No bluetooth after system restore

Thank you for your reply.

I mean I have used a Windows system restore point. I tried restoring bluetooth with commands in CMD (sfc/scannow; DISM /Online.....) and by updating and uninstalling devices in the device manager. Update did not work. Uninstalling bluetooth devices made Bluetooth disappear out of the hidden devices list.
All my steps I took worked but did not change anything in my bluetooth device list.

I am using the bluetooth of my mainboard. MSI Z370M Gaming Pro AC
My guess would be, that disabling the bluetooth network adapter before using a system restore point, disabled Bluetooth after using the system restore point.

In the device manager I get this message in the USB Device list for a unknown USB Device:
Windows has stopped this device because it has reported problems. (Code 43)
A request for the USB device descriptor failed.

Bluetooth disappeared from Device Manager

I have the same problem as Benjamin with an Acer Aspire Switch 10. Was working fine with Bluetooth speaker. Now all trace of Bluetooth has disappeared from Device Manager. The Bluetooth troubleshooter tells me my tablet is not compatible with bluetooth!
I have tried re-installing the Broadcom Bluetooth Driver from the Acer site but to no avail and tried most of the other suggestions including windows update listed in Benjamin's post.

Appreciate any help
