Microsoft is pushing out a new firmware update for both the Surface Pro 4 and Surface Book this evening. It's not entirely clear what the update addresses on either device, as the Surface Update History page (opens in new tab) hasn't yet been updated with a change log.

Update: As of 9:45 PM ET Microsoft has posted the following changelog for the January 27 firmware update

Surface Pro 4 January 27 update

  • Surface Embedded Controller Firmware (v103.899.256.0) adds battery charging enhancements and thermal tuning.
  • Surface Fingerprint Sensor driver update (v2.2.10.6) improves accuracy.
  • Wireless Network Controller and Bluetooth driver update (v15.68.9037.59) improves access point compatibility and throughput on 5Ghz networks.

Surface Book January 27 update

  • Surface Embedded Controller Firmware (v88.899.256.0) adds battery charging enhancements and thermal tuning.
  • Wireless Network Controller and Bluetooth driver update (v15.68.9037.59) improves access point compatibility and throughput on 5Ghz networks.
  • Surface DTX driver update (v1.3.202.0) improves detection of the Surface keyboard to the clipboard.

In addition to the updates list above, the following additional update is available for Surface Book devices that have the optional NVIDIA GeForce GPU discrete graphics chip:

  • NVIDIA GeForce GPU update (v10.18.13.5914) improves stability.

For now, you should be able to grab the latest firmware on your Surface Pro 4 or Surface Book by checking Windows Update. Once Microsoft updates the Surface Update History page with details, we'll update this post. In the meantime, let us know if you happen to notice anything new after installing the update.

  • Fixes for common complaints? I own neither, but the Surface Pro 3 gave me all the reason I need to sympathize with people having connected standby issues.
  • I was having connected standby issues with Windows 10 on my SP3 until I realised the power profile had been switched off Balanced (the only one that connected standby works properly on). Once I changed that everything went back to normal. You may have already checked it, but if not it's worth a look.
  • MS pushing a new 5 delays..... This is how i read it first time LOL
  • Somehow, that wouldn't surprise me in the least. lol
  • I would just laugh LOL
  • I have an older just plain whitebread Surface with Windows RT. I also got the update, but I can't tell what it's done. Also, it seemed like it took an unusually long time for it to update. Or mayb it was just me ... 
  • The fan went bonkers on my surface book for a second when the update installed. Scared the crap out of me.
  • That's actually common for UEFI/BIOS-level updates with the Surface devices. Not sure why.
  • I guess during the update Surface cannot control de fan so, just in case, it spins it at max to prevent any (unlikely but possible) overheating at that critical moment.
  • Could as well be a fan test and not due to heating or something.
  • Changelog for Surface Pro 4 is up! January 2016 updates The following update will be listed as “System Firmware Update – 1/27/2016” when you view your update history. Note When Surface updates are provided via the Windows Update service, they are delivered in stages to Surface customers. As a result, not every Surface will receive the update at the same time, but the update will be delivered to all devices. If you have not received the update then please manually check Windows Update later. Surface Embedded Controller Firmware (v103.899.256.0) adds battery charging enhancements and thermal tuning. Surface Fingerprint Sensor driver update (v2.2.10.6) improves accuracy. Wireless Network Controller and Bluetooth driver update (v15.68.9037.59) improves access point compatibility and throughput on 5Ghz networks.    
  • I miss my surface book but i am soooo glad I returned it. I'd be so much more upset if I still had it and it still has seriously annoying issues. Id hoped it wasn't going to take them too long so I kept the dock but considering that changelog maybe I should have returned it as well since the more time passes, the less likely I'll be to purchase what is basically the 2015 model.
  • Why would you keep the dock, paper weight?
  • Waiting to buy a functional device
  • Suck to be you, I'm not having any issues with my surface book. Best device I have ever owned.
  • Same here owner of surface pro 4 best thing ever...totally lovin it.. :D
  • So where's the fix for screen flickers when playing video on my Surface Book?
  • I have screen very annoying screen flicker issue while playing videos on my surface pro 4. I just did a reset wiping all data. And that helped . Give it a try.
  • I got happy when I saw the update to 5Ghz networks. I have 300 Mbps internet but was only getting around 60-100 Mbps. Tested after the update and still the same. No issues with my older laptop. Anyone else have slower than normal internet speeds or know a fix?
  • I understand the complains but we all have to be honest people, we bought 1st generation devices. I did with the RT, Surface 2, Surface 3, PRO, PRO 2, PRO 3, now with the Book and I feel that from the RT till now all became a LOT better (and not only MS devices running windows). So, complain but don't forget they are first generation devices issues, that is just the way it is.
  • I agree somewhat. The older devices are Microsoft getting into the hardware market.however, as an owner of both a SP4 and SB, it is very disappointing when you pay $2,800 for a computer that blue screens half the time you detach it, and doesn't connect to 2 external displays properly via their expensive dock
  • I have the dgpu i5 version and the blue screen happened I think only 3 times in two months when connecting, disconnecting the screen. I'm sorry to hear that it happens much more often to you.

  • As is unfortunately to be common with these updates, this one seems to have issues. I'm on an i7 Surface Book (dGPU) and it basically borked my ability to connect to WiFi...
  • For what it's worth, I think i fixed my issue by uninstalling the Avastar driver in device manager, then rebooting. (Something that's been a handy trick since the Surface Pro 1 days.) 
  • THANK YOU! You're a life saver! The update also broke my SP4 wifi. I'm a first time SP user so I don't know this trick.
  • I also have the i7 with GPU, and had no problems at all with the WiFi or anything else (so far). I hope it stays that way.
  • I wish I had read your post about 20 minutes ago. Same issue, same fix. I still can't see any wifi networks when I click on the task bar icon so I don't think I'm out of the woods yet, but at least I can connect to a network now.
  • I hate to be that guy in the comments, but I can't be the only one pining after the elusive Windows 10 Windows Central UWA. Any updates on it?
  • Yet you are that which you hate to be...
  • Awesome!!
  • How do you set the dark theme in settings panel
  • I was wondering too
  • Registry edit. The is an article on WC if you search a bit
  • Why does a company get a pass for selling a product at premium prices that fails to perform as advertised because it's a first generation product? Actually, my older surface pro outperforms my sp4. I'm really getting sick of waiting for all the problems to be fixed.
  • Love my SP2! I just can't make myself give it to anybody else to use. (which is awful since I am not someone who hoards) But my SP4 is just too wicked to put down. So I can't say "my older surface pro outperforms my sp4". Edit: Having said all that, after this firmware update, I had to reset Hello. She acted like I was a stranger. One click run through "improve recognition" and she decided we were soul mates after all.
  • 8 Devices later and we still have "fixes" for the Avastar WiFi bluetooth... How many chances do they get? SMH
  • I hope this fixes my problem with slow downloads on Steam
  • I haven't seen any improvement on my 5Ghz network and still experience way slower than normal download speeds. Have you seen any improvement?
  • the drivers say they are from november 15 i think. seems so outdated lol. it didn't fix my issue with My Steam downloads dropping to 0
  • Nope same ol' speed drops. i don't think this will be fixed anytime soon
  • I downloaded the old drivers from Microsoft, installed only the network driver, reinstalled the new driver, did the regedit fix and I'm getting much better speeds around 200 Mbps. May want to give that a try. I also did a factory reset on my router and changed the network card to only 5Ghz networks just to cover all bases.
  • my speeds on a speed test are normal but when i download games off Steam, they drop to 0 kb/s. is this a similar problem you had or were your speeds slow during speed tests too?
