Fail to install Windows update

[Zsolti]

I can't install Windows 10 update because my computer says mi BIOS version is out of date. Even after successfully installing a BIOS update,my laptop displays the same error message. How can I fix this?

Thanks

From your screenshot, it looks like your PC is trying to install the 1903 Feature Update using Windows Update -- which is the least work, but unfortunately, also the most troublesome and least reliable method.

An alternative that might work is creating Win10 installation media and using that to do the Feature Update.  You can download and create the media from this tool:  Windows 10 download

When you have that, insert it into your PC (do NOT boot from it), select the folder containing the files, right-click on the setup.exe file selecting Run as Administrator.  That will start the update.
