Firmware updates may not be the most exciting thing in the world, but they can deliver essential security and driver updates. This time, Microsoft has rolled out three at the same. Users of the Surface Book, Surface Studio, and Surface Pro 4 will all see improvements.

For Surface Studio, the main focus is security. Updates to the management engine, UEFI firmware, and dTMP firmware fix a ‘potential security vulnerability’. A final update to the intel management engine interface improves recovery for Connected Standby.

However, a much bigger set of updates have come to the Surface Book. Here’s Microsoft’s full list:

Windows Update History Name Device Manager Name
Intel Corporation – HIDClass – 1.2.0.99 Intel(R) Precise Touch Device – Human Interface Devices
  • 2.0.99 improves multi-touch and pen connectivity when the device wakes from sleep.
Intel Corporation – System – 9.21.0.2853 Intel(R) Smart Sound (SST) Audio Bus – System devices
  • 09.21.00.2853 improves video performance in some applications.
Intel Corporation – System – 9.21.0.2853 Intel(R) Smart Sound Technology (SST) OED– System devices
  • 09.21.00.2853 improves video performance in some applications.
NVIDIA – Display – 23.21.13.8808 NVIDIA GeForce GTX – Display adapter
  • 23.21.13.8808 improves device graphics performance.
Realtek – Media – 6.0.1.8242 Realtek High Definition Audio(SST) – Sound, video, and GC
  • 6.0.1.8242 improves Cortana speech recognition.
Microsoft – Storage -11.0.0.1 Surface NVM Express Controller – Storage Controllers
  • 11.0.0.1 improves storage performance.
Surface – System – 2.27.136.0 Surface DTX – System devices
  • 2.27.136.0 improves system stability.

This time, there are some interesting improvements. Notably, users should experience better video performance, better dGPU performance, and more accurate speech recognition. It’s not clear how significant these increases are, but they’ll be appreciated all the same.

Surface Pro 4 Firmware Update

The Surface Pro 4 has received similar security updates, but also some minor improvements to stability. Here’s the full list:
