Microsoft released a new set of Spectre (variant 2) security updates.
Right now the release deals with devices running on Skylake CPUs and Windows 10 Fall Creators Update or Windows Server version 1709 (Server Core).
The company will continue to work with chipset and device makers as they offer more vulnerability mitigations, said John Cable, director of program management for Windows Servicing and Delivery.
The updates are available for download and manual installation from the Microsoft Update Catalog. This update will not be available via Windows Update.
“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 KB Article for these Operating Systems as they become available to Microsoft,” the company said.
When the news first broke about the Spectre and Meltdown issues, vendors were quick to offer a fix, however, the solution presented a new list of problems.
In order to receive the update, the system must sport a specific registry key, and if it doesn’t, customers will not receive Meltdown, Spectre, or any future Microsoft security updates.
The key can be set up by compatible AV software or by users themselves.
