Microsoft has dropped a new Windows 10 2020 Insider Preview Build to Fast ring Insiders. Today’s Preview Build brings an improved Bluetooth pairing experience. But more importantly, it also brings back optional updates to Windows 10. These will show up in Windows Update as a new listing. Here is the complete changelog:

For Windows 10 version 1803, we announced a new streamlined experience for pairing supported Bluetooth devices. The idea was simple – if a supported device was nearby and in pairing mode, we’d show a notification that prompted you to go through pairing. This saved you from opening Settings yourself and finding the right place to go. Today, we’re rolling out an update with improvements we hope you’ll like.
