Microsoft's Surface Book lineup has gone a couple of years without a hardware refresh - though that may be set to change soon - but the first and second-generation models are still supported with driver and firmware updates every now and then. That's the case today, with a handful of updates heading out to both generations of the device.
For both the Surface Book and Book 2, the list of updates is short, but the second-generation model does have three updates available:
|Windows Update History Name||Device Manager Name||Version and Update|
|Marvell Semiconductor, Inc. – Bluetooth – 15.68.17017.115||Marvell AVASTAR Bluetooth Radio Adapter - Bluetooth||
|Marvell Semiconductor, Inc. – Net – 15.68.17017.115||Marvell AVASTAR Wireless-AC Network Controller – Network adapters||
|Surface – System – 126.96.36.199||Surface DTX – System devices||
As for the first-generation Surface Book, the list is actually just one item, and it's the same as the last one on the list above.
The updates should be available now for users running Windows 10 version 1903, also known as the May 2019 Update, or newer.
