Microsoft pushes out new Surface UEFI and Firmware October updates

Microsoft is releasing new firmware updates for the Surface Book (and presumably Surface Pro 4) starting today on October 27. We checked two of our machines – one on Release Preview, the other on Fast Ring – for the updates and both are receiving an assortment of firmware and driver updates.

Here is what we have spotted when checking Windows Update:

  • Driver update for Marvel AVASTAR Bluetooth Radio Adapter
  • Driver update for Surface DTX (Surface Book only)
  • Driver update for Surface System Aggregator Firmware
  • Driver update for Surface Embedded Controller Firmware
  • Driver update for Surface UEFI

Some of these changes may be general fixes and improvements, while others may be related to current or forthcoming changes in Windows 10 including Redstone 2 aka "Creators Update" due early next year.

This is the first batch of firmware and driver updates since the end of August.

Microsoft has not posted the changelog just yet, but they usually do in the following 24 to 36 hours, and we'll run a second article once that happens with more details.

  • Nothing showing up on my pro 4 yet.
  • Not here too! Not Insider!
  • Completely barren on the SP4 here as well
  • Could they push out a new Surface Phone too?
  • Just updated the firmwire on my SB before checking this, interesting.
  • Hey Dan! Aren't we having an article on Panos Panya. The way he delivered the presentation I am sure he will shed some tears when he comes to introduce the Surface Phone;")
  • Surface phone won't be released if it doesn't have any killer features because Surface Pro is more than a tablet, Surface Book is more than a laptop, Surface studio is more than a AIO
  • if it's up to Panos and his team, Surface Phone will be more than a Phone :) I really love the enthousiasm Panos has when taking the stage to talk about new stuff :)
  • Not just up to Panos and his team, without Terry Myerson and the Operating Systems Group adding features Panos can take advantage of his hands are tied. That's why you hear rumors about the phone's release being postponed to Fall 2017 or even 2018: they're waiting on future Updates to Windows 10, be it RS3 (Fall 2017) or RS4 (2018).
  • I thought RS3 / Creators Update would be released Spring 2017?
  • Creators Update is RS2. RS3 is rumored to be released Fall 2017.
  • Can someone help me get rid of this error msg in Windows? It's some bug after installing Office 365 64-bit. Windows does not see default e-mail client anymore even if it's set in "defaults" to stock Window Mail. PS. I don't have or use Outlook. "Either there is no default mail client or the current mail client cannot fulfill the messaging request"
  • Did you post in the forums? Lots of smart people hang around there. Give it a shot...
  • As for me it was a non event as the the most anticipated Surface/ Windows phone issue was not touched. Ain't there anyone to ask the Microsoft bosses why they have become so silent on the Win10 phone which they were touting as the future of Microsoft last year!
  • The Surface team will not risk its brand equity on a device that is doomed to fail. I believe they will release a phone only when the Windows team makes a compelling rationale for customers. Live Tiles are not enough anymore, and Continuum, in its current state, is insufficient.
  • I am sure they are developing something. They surface phone has to be something new where it defines it's own category. Continuum will play a role but other things will need to be introduced. Even re-introducing the pen would be huge. A couple of camera innovations and other thing and you will have an exciting phone that the masses will actually be interested in. Look at the studio video in YouTube, there is already 5mil views.
  • A Windows phone whether for enterprise or consumer will need to have apps. If they can't fix that, they might as well not even work on it. They need some way to just run Android or IOS apps.
  • Come on, nobody really expected them to announce it, did they? I was really doubtful they'd even mention it, because if it does happen, its still a long time away.
  • Don't know if anyone ever said Win10 phone was the 'future' of MS. How do we even know the mode(s) of computing in the 'future'?
  • I was happy for the shoutout to the X3.  Win10 Mobile was not completely shunned :)
  • No firmware update received on my (fast insider Windows 10) on my Microsoft Surface Pro 4
  • sp3 - the forgotten one. May be sp3 owners not getting in on the firmware party is a blessing because each time they roll out a firmware, they break something else anyway i.e WiFi, battery not charging, etc. And then another firmware to fix another firmware's mess... like a never ending cycle. Essentially using all the Surface poor souls as beta testers.
  • I am not sure there is anything else that needs fixing on the SP3. Mine pretty much works perfectly.
  • My Surface Book got the updates and also an Nvidia GPU driver update.
  • Nothing yet for my SP4
  • No updates on my SP4 either.
  • Got all updates yesterday but doesn't resolve my APC_INDEX_MISMATCH stop error, i have since update .351
  • I'm seriously hoping these updates fix my keyboard disappearing issue on the Surface Book that began after the August firmware updates!
  • I guess surface phone will be phone with full version of windows 10. No windows for mobiles anymore.
  • I don't think so
  • I turned on my surface book this morning and it did the firmware update. When I got back into Windows the screen flickered many times. I went to Windows update and it said to restart to finish surface dtx update. Restarted and it has been stuck on getting Windows ready don't turn off for 45 minutes now
