What you need to know

  • August 2021's Surface Book 2 firmware update drop is here.
  • Camera and audio stability are getting improvements.
  • Security vulnerabilities are being handled.

Another month, another firmware update for your favorite Microsoft device. In this case, we're looking at the Surface Book 2's August 2021 assortment of firmware goodies. Expect camera and audio improvements, as well as security vulnerabilities being addressed and improved stability for "Surface Dock 2 scenarios," as Microsoft puts it.

Specifically, the August update:

  • Addresses critical security vulnerability and improves device stability.
  • Improves device stability and reliability with Surface Dock 2 scenarios.
  • Improves camera and audio stability and reliability.

You can check out Microsoft's support page for a detailed breakdown of all the individual components affected by the firmware update to bring about the aforementioned improvements. It's mainly a laundry list of display adapters, Realtek High Definition Audio, and camera items that all come together to amount to the changes already listed.

The update is for Surface Book 2s running Windows 10's May 2019 update, version 1903 (19H1), or anything more recent than that. It's not a big update, and there's nothing major on the firmware slate that'll completely overhaul the Surface Book 2 experience, but still, it's never a bad thing to receive camera, audio, security, and Bluetooth improvements.

The Surface Laptop 3 and Surface Go have already received their updates for August 2021, so if you have either of those devices, feel free to check Microsoft's pages for the corresponding firmware logs.

And if you want to stay in the loop when it comes to Windows updates, know that the latest Windows 10 update put an end to PrintNightmare... for a few minutes, until it became apparent that PrintNightmare isn't going away no matter how hard Microsoft tries.
