Microsoft Releases KB4100347 for Windows 10 April 2018 Update

Recommended Posts

Systems that have already been upgraded to the Windows 10 April 2018 Update (version 1803) are now provided with a new update that brings more mitigations for the Spectre Variant 2 vulnerability in Intel processors.

Windows 10 update KB4100347 is thus only shipped to computers with Intel processors, and it is available right now via Windows Update and on Microsoft’s Update Catalog for manual downloads.

Among the CPUs getting microcode update as part of KB4100347, worth highlighting are Skylake and Kaby Lake series, both of which have already received other security fixes in the previous months from Intel and Microsoft. The full list of chips getting further mitigations with this update is available here.

“This update also includes Intel microcode updates that were already released for these operating systems at the time of release to manufacturing (RTM),” Microsoft explains.

Windows 10 April 2018 Update

Spectre Variant 2, further detailed in CVE 2017-5715, is one of the vulnerabilities found in Intel processors and disclosed in early January. Microsoft and Intel worked together on releasing security patches and further mitigations for affected processors on Windows 10, and the two companies have since released several updates, with additional improvements projected to land in the coming months.

Windows 10 April 2018 Update is getting its first Intel microcode update after the launch. This particular OS feature update, also known as version 1803, was launched as a manual download on April 30 via Windows Update, while on May 8 Microsoft officially kicked off the automatic rollout via Windows Update.

April 2018 Update has until now received just a single cumulative update on this month’s Patch Tuesday, bringing a rather limited collection of fixes, despite the significant number of bugs reported lately. Today’s security update does not include any other improvements besides the Intel microcode update, and no bug fixes are part of the release.

This is what I got after this update ;

It takes two seconds more in boot-time , went from 8 to 10 seconds ;  a small price for more safety ..........:D

A computer that will boot in 8-10 seconds does not exist and is not even theoretically possible if using current technology.

This update is a standalone update that is available through the Microsoft Update Catalog and targeted for Windows 10 version 1803 (Windows April 2018 Update) and Windows Server 2016 Version 1803 (Server Core). This update also includes Intel microcode updates that were already released for these operating systems at the time of release to manufacturing (RTM). We will offer additional microcode updates from Intel through this article for these operating systems as they become available to Microsoft. Please ensure that mitigation against Spectre Variant 2 is enabled through the registry settings that are documented in the following article:

Windows Server guidance to protect against speculative execution side-channel vulnerabilities

 

Consult with your device manufacturer and Intel via their websites regarding their microcode recommendation for your device before applying this update to your device.

I can only say that (or so much) if you have the best processor and the best SSD, you can get about 20-30 seconds and if you have HDD with  an optimal size, then about 3 times longer. That's about 60 seconds. And no way faster. Also You can not measure  with a clock or a stopwatch, but you need to measure with very precise and specific software. You even may have it in Your computer, but even those do not do this work always correctly. For example You may have Wise Care 365, where it is included or IObit Advanced System Care, where it is also included.

Running 1803 and it says I'm protected from Spectre. Windows updates are up to date. This must be a manually update, not sure if it's even needed.

performance drop is only noticeable in servers and only happens in CPUs affected by Meltdown, and only Intel CPUs are affected by Meltdown, while AMD CPUs are not affected by Meltdown and there is no performance drop.
