Earlier this year, Intel announced that they have
discovered Meltdown and Spectre vulnerabilities in their
processors. The company later released microcode updates for
some of its CPU platforms to patch them against the Spectre
Today, Microsoft is rolling out yet another Intel microcode
update for all supported versions of Windows 10 operating
Systems that are powered by Windows 10 April 2018 Update
(version 1803) are now provided with a new microcode update
that brings more mitigations for vulnerabilities. KB4346084 is
available for Windows 10 April 2018 Update (version 1803)
devices and the patch addresses the latest vulnerabilities.
It’s worth noting that the patch won’t show up on devices via
“This update is a stand-alone update targeted for Windows 10
version 1803 (Windows 10 April 2018 Update) and Windows Server
Version 1803 (Server Core),” the company explains. “By
default, this mitigation is on for Windows client systems.
Therefore, no action is required”.
If you’re using Windows 10 Fall Creators Update and your PC is
unpatched, KB4090007 will show up via Windows Update.
You’re not supposed to force the patch on your device as long
as you are running the latest version of the operating system.
Again, you’re not supposed to force any update on your PCs. If
you’re familiar with the development, you can open the
Microsoft’s Update Catalog website and deploy the patches
manually. Today’s security update does not include any other
improvements besides the Intel microcode update.
