Microsoft released today three additional Windows update packages —Microsoft Releases KB4100347, KB4134660, and KB4134661.
The first of these (KB4100347) is security-related, while the other two (KB4134660 and KB4134661) are privacy-related.
KB4100347 is related to the never-ending saga of Spectre v2 mitigations. This update package contains additional CPU microcode updates for Intel processors.
The update is addressed only for Windows 10 version 1803 and Windows Server version 1803 releases, also known as the April 2018 Update.
The updates contain only Intel-specific code, which Microsoft agreed a while back to help propagate to users faster than relying on motherboard providers to include the microcode patches as BIOS updates, a process that would have taken months, if not years.
KB4134660 and KB4134661
“This Windows update provides a notification of an improved privacy experience on upgrade to the Windows 10 April 2018 release,” their description reads.
The two updates are targeted at Windows 10 Version 1703 and Windows 10 version 1709 users only.
All three updates are available via Windows’ automatic update installer or as separate update packages via the Microsoft Update Catalog portal.
