Microsoft has today released new important updates for all supported versions of Windows 10 operating system. You can download Windows 10 KB4078407 offline installer from Microsoft’s Update Catalog and mitigate the vulnerabilities. In a support page, Microsoft says that users may need to manually deploy Windows 10 KB4078407 to enable mitigation against Spectre, Variant 2.

Needless to say, the patching process of Meltdown and Spectre hardware bugs disclosed earlier this year is more complex than initially thought. While Microsoft patched the vulnerabilities back in January, the company is still releasing new updates to mitigate Spectre, Variant 2 vulnerabilities without affecting the performance.

Microsoft last month shipped several patches for Windows 10, and today the company is releasing another set of security updates. Windows 10 KB4078407 is aimed at the Spectre Variant 2 vulnerability and can be installed on any supported version of Windows 10. It is, however, worth noting that Microsoft is not rolling out the update over-the-air, as a result, you’ll need to download and deploy the update manually.

Microsoft says that you can install the patch in Windows 10 to enable the Spectre Variant 2 mitigation that was originally believed to be nearly impossible to exploit. Of course, the update doesn’t come with any new changes or features. While the update will patch the vulnerability, microcode patches from hardware vendors are required and recommended as Microsoft’s latest update only protects systems on the software side.

Microsoft has released another update KB4091666 aimed at the original Windows 10 version 1507 with Intel processor.

The software giant has also published KB4090007 for Windows 10 Fall Creators Update, KB4091663 for Creators Update, and KB4091664 for Anniversary Update devices. You can find the download links below.

Microsoft is today adding support for the additional processors. The company says that Xeon E3, Haswell, Haswell Perf Halo, Haswell Server E (EP and EP4S), Haswell ULT, Broadwell DE series, Broadwell Xeon E3, Broadwell H 43e and Broadwell U/Y processors are now supported.
