On Windows 10 and I've already paired the Bluetooth headset previously. When I turn it on it connects to the last used device (my iPhone; I manually disconnect).
How do I tell Windows "Please connect to this device you've already paired with?". The current Bluetooth UI doesn't seem to have this very ordinary option.
The laptop is a Macbook Pro, booting to Windows 10 via Bootcamp. Bluetooth otherwise works fine.

I think I have finally found a reliable answer for this.
For those that like shortcuts, Win+K from anywhere in Windows takes you directly to the "Connect" page and allows you to click your device and connect.
Why this isn't anywhere in the devices or Bluetooth connection settings pages I will never know. However, Win+K is about as quick as a shortcut as I could ask for so this is solved for me.
