Earlier this month, Microsoft started helping Intel by rolling out firmware updates to protect against Spectre and Meltdown vulnerabilities. At the time, Microsoft and Intel only released updates to a couple of Skylake processors.
Today, Microsoft is rolling out the updated firmware to more processors, including some Kaby Lake and Coffee Lake processors. The updates are only available to devices running Windows 10 version 1709, and it’s only available through the Microsoft Update Catalog. You can find the full list of processors that have the updated firmware here.
In addition to bringing Intel’s updated firmware to more processors, Microsoft is bringing software updates to protect against Meltdown to x86 editions of Windows 7 and Windows 8.1 today. The company is also removing the anti-virus compatibility check in Windows 10 that prevented some users from getting its own security updates, though it will continue to closely monitor anti-virus software for compatibility issues going forward.
