Wish I could help, because I successfully connected my Win7 BT to Echo and BT speakers a few months ago, but trying to get it to work today was unsuccessful. Something in the setup must have gotten changed with a Win7 update. Win7 is definitely showing its age. Since I have much better ways to use BT, I am going to forget about using the Win7 BT (and not even mess with it from my Win10 laptop.) Sorry I can't help.
