Surface Laptop and Windows Insiders get new UEFI and firmware update

Starting on September 12th, we noticed one of our Surface Laptops (Windows Insider, Fast Ring) picked up no less than seven new firmware updates through a Windows Update check.

Today, we've seen the updates come through on two other Surface Laptops (Windows Insider, Release Preview). However, Microsoft has not announced any changes on its Surface Update History page (opens in new tab).

Some of the updates that came through on 'Patch Tuesday'.

Most of the updates appear to change from generic 1.0 drivers to formal ones for the Surface Laptop with actual build numbers. Here is what we could document:

  • UEFI going from 136.1668.769.0 to 136.1736.769.0
  • Keyboard driver updates from generic 1.0.0 to 135.1713.0
  • System Aggregator updates from 1.0.0 to 135.1704.1.0
  • Trackpad driver updates from 1.0.0 to 2.122.2683.0

Also, there are updates for Surface Integration Service Device, Surface Integration, and System.

Microsoft is evidently doing a slow rollout and letting Windows Insiders get the new drivers and UEFI firmware (BIOS) before it hits Windows 10 production for non-Insiders.

Presumably, if there are no major bugs found and the drivers will go out to all Surface Laptop owners in the coming weeks. At that time, Microsoft will likely post the full changelog, which we'll revisit.

Very few sytem bugs have been reported with the Surface Laptop making these new drivers likely more optimization than proper fixes.

  • I would like to recommend some useful links for where you could get drivers for windows.
  • Very few sytem bugs have been reported with the Surface Laptop
    Can confirm. Haven't had a single issue with my SL.
  • Pathetic! So now you're not only guinea pigs for their OS testing, they want you for the drivers also. How PATHETIC Microshit can be really! How cheap can they work FFS! that they won't have a proper testing team.
  • Pathetic that people who opted-in to be beta testers are being treated as ... beta testers...?
  • I have said this from the beginning of the suckers....i mean insiders program.  All they are, is the testing department for MS.   Free labour for MS.  congrats on working for nothing.
  • It's your own fault for switching the toggle for Insider Previews to ON thus becoming a sucker for free labor HELPING everyone and YOURSELF in the long run by having THOUSANDS of potential betatesters reporting issues instead of just a mere dozend.
  • @Durahl You clearly have no idea how a proper testing process should be to have decent quality. Does not matter that there is a switch to On, MS should have their own testing team! Ever since they started with the insider program, there was nothing but mediocre quality delivered to non insider users. Bugs everywhere!
  • it's obviously not working since the patch tuesday's latest patch has slowed my computer to a crawl.   BRUTAL!
  • Durahi,  Unless Microsoft pays me,  that toggle will never be on, on my systems....sorry...NO SUCKER HERE.  
  • Anyone with any computer savvy won't use their main PC for Insider testing, they'd either be using a separate partition or a virtual machine to test with. Anyone who isn't computer savvy shouldn't be using the insider programme at all. No sympathy for anyone using beta software knowing it's beta software and then complaining when issues arise
  • This was not insider updates was the production patch.   screwedup my machine.
  • I guess it took some time for everything to sort out.  My systems are back to normal.
