How to completely remove a Bluetooth device from Win 10?

I have tried for days to remove a Bluetooth Speaker that did not install proper, I remove it try to re-pair does not pair, then upon reboot it is installed again with error. No matter how many times its removed Windows keeps re installing the device on its own.

How do you completely remove a bluetooth device, all traces so you can start fresh?

I have searched the internet for 2 days and no one has the answer yet. Not even on the MS forums

That’s not Windows forum. You should ask on MS or speakers producer forums.
