In February, Intel released microcode updates to
their OEM partners for CPUs such as Kaby Lake, Coffee Lake and
Skylake-based platforms. Microsoft has already rolled out the
firmware updates to Windows 10 version 1709 and older.

Today the company is rolling out the Intel firmware update to
all supported devices with Windows 10 April 2018
Update (version 1803). It is worth noting
that Windows 10 KB4100347 is only shipped to PCs with
Intel processors, and it includes more mitigations for the
Spectre Variant 2 vulnerability. CVE 2017-5715 (Spectre
Variant 2) is one of the vulnerabilities found in Intel CPUs
and disclosed earlier this year.

“Based on these efforts, we have now released production
microcode updates to our OEM customers and partners for Kaby
Lake- and Coffee Lake-based platforms, plus additional
Skylake-based platforms. This represents our 6th, 7th and
8th Generation Intel® Core™ product lines as well as our
latest Intel® Core™ X-series processor family,” said Navin
Shenoy, executive vice president and general manager of the
Data Center Group at Intel Corporation.

Microsoft says that the update is available
through Windows Update and it would download automatically
if you turn on automatic updating in Settings. You can

Ever since Intel disclosed the Meltdown and Spectre
vulnerabilities, Microsoft and Intel together rolled out
several updates to mitigate them. Microsoft has already fixed
the vulnerabilities, but deploying the most recent patch is
still recommended. More updates with security fixes are
expected to land next month.

Windows 10 April 2018 Update was launched as a manual download
on April 30 via Windows Update. While the update comes with
several new features, the reports claim that the feature update
is causing more harm than good on some hardware configuration.
However, a significant number of bugs were reported lately and
Microsoft is working on a fix which could land next month.
