[German<\/a>]Microsoft has released several microcode updates for the still supported Windows 10 builds in revised form. These are the updates KB4090007, KB4091663 KB4091664 and KB4091666. <\/p>\n

\"\"In the blog article Windows 10: Microcode updates KB4090007, KB4091663, KB4091664, KB4091666, KB4078407<\/a> I wrote about new microcode updates for various Windows 10 builds at the end of April 2018.  <\/p>\n

A new V4 vulnerability<\/h2>\n

On May 21, 2018 Microsoft (in the advisories ADV180012<\/a> and ADV180013<\/a>) and Intel (here<\/a>) revealed a new Spectre V4 vulnerability in Intel processors. I had posted in the blog post Google and Microsoft unveil Spectre V4 CPU vulnerability<\/a>, and Intel had announced new microcode updates. <\/p>\n

Refreshing Windows 10 Microcode Updates<\/h2>\n

Colleagues at deskmodder.de<\/a> have noticed that Microsoft has updated the downloads in the Microsoft Update Catalog for various microcode updates as of May 21, 2018. Microsoft is silent about whether the fixes for the Spectre V4 vulnerability mentioned above have already been integrated into the microcode update. <\/p>\n

\n

However, the release date May 21, 2018 for the packages in the Microsoft Update Catalog and the announcement of the details of the ADV180012<\/a> and ADV180013<\/a> vulnerabilities suggest this – but you can't be sure. Microsoft first wants to provide firmware updates for its Surface devices (see<\/a>).<\/p>\n<\/blockquote>\n

The KB articles linked below describe which CPUs are supported by the microcode.<\/p>\n
