There are two ways to get the BIOS version in Windows 10 without having to access the BIOS options themselves.
1. In the 'Type or speak to me' text box on the bottom of the Windows screen (next to the button you use to shut the PC off), type in the word command to find the Command Prompt application. This is a text interface for Windows.
In the command prompt window, paste the following command in,
wmic bios get smbiosbiosversion
The other method is:
2. Into the same 'Type or speak to me' box, put the phrase system info to find the System Information application, which displays the details of your PC's configuration. In the 'BIOS version / date' category, it will display your current BIOS version.
Thanks for the reply.
I'll have to check the version in the BIOS itself anyway if I plan to update it before actually installing the OS. Although I suppose it doesn't really matter which I do first. I'll check once I actually get the NUC.

I managed to track down the download page for NUC BIOS version 0031.
The download page recommends using the Express BIOS setup option. The zip file in the Available Downloads sidebar for this installation file is
I note that you want to use iFlash. The download file for that is:
As for locating BIOS 4026 ... it does not seem to exist, even in general Google searches. I suspect there may be a typo in the instructions and it actually meant 0026, since that NUC BIOS number did exist and was used on 2014-era Haswell architecture models.

When you see a BIOS number like 4026, this usually means that this is a re-release of BIOS 26 with some specific patches added to it. If it is not posted in the Download Center, it is likely because most folks do not need access to it. Only in very rare (emergency) situations will Intel distribute a patched BIOS release and, if this happens, it is usually done directly; not via the Download Center. I can see from the BIOS 31 release notes that it was declared to be the first production BIOS. This means that the BN NUCs will ship with this particular BIOS (or perhaps, over time, an even newer one) already installed. Likely only those folks who received pre-production units will need to actually install BIOS 31.
The iFlash, F7 and EBU (Express BIOS Update) methods for installing the firmware are all essentially the same. The firmware installation capsules contained within a .BIO file are placed into memory and the system is restarted. During the subsequent POST (Power-On Self-Test), the (existing) BIOS sees that valid installation capsules are present in memory and it installs the contents of these capsules as appropriate. What you are downloading depends upon what installation method you are going to use:
- For the (recommended by me) F7 method, you are downloading just the .BIO file. You place it on a flash disk and, while reboot the system press the F7 key and use the subsequent dialog to point to the flash disk and to select this .BIO file.
- For the iFlash method, you are downloading a .ZIP file that contains the iFlash executable and the .BIO file. You place these files onto a DOS-bootable flash disk and boot from this disk. Once booted, you run the iFlash tool specifying the name of the .BIO file.
- In the EBU case, the BIO file is built into the (Windows) executable image and loaded from there. You download the .ZIP file, extract the executable and run it.
See here for more information: Intel NUC BIOS Update Instructions. There is, of course, a fourth method for installing a .BIO file, namely the Recovery Method. While the installation process is essentially the same, the methods used to install the capsules and the rules applied with respect to versions allowed, etc. is very different. See here for more information: Intel NUC BIOS Recovery Update Instructions.
Hope this helps,
Great information, S. I've noted it for future reference. Thanks so much for that.
