BIOS upgrade via Windows Update?

2020-04-06, 15:49 PM

I have an X1 Carbon 6th gen on the latest Windows 10, and before today I was on BIOS 1.45. I normally wait a month or two for BIOS updates to see if there are any bugs or bricks. However, today Windows update installed the update pictured below and asked for a reboot. During the boot process, I got the regular Lenovo splash screen with a progress bar and text as pictured below it (image from Google, not my own but it looked exactly the same). Having never seen this before, I checked the BIOS version in msinfo32 and found that it had been updated to 1.46, which appears to be the latest version on the Lenovo website. Is Lenovo pushing BIOS updates through Windows Update now?

Yes, there are some BIOS updates in Windows Update (Microsoft is forcing us to do this).  Fortunately, you can disable it if you don't want to receive these updates:

  1. reboot and press F1 to enter BIOS Setup
  2. Go to Security -> UEFI BIOS Update Option
  3. Set "Windows UEFI Firmware Update" to Off
  4. Press F10 to Save/Exit BIOS Setup
