Intel last week confirmed reports that the firmware updates it was pushing out to protect against Spectre and Meltdown vulnerabilities were faulty and were causing reboot issues. Microsoft over the weekend responded to Intel’s disclosure and has issued an out-of-band update that will allow users to disable Intel’s faulty patch, particularly the one that mitigates against Spectre Variant 2.

“While Intel tests, updates and deploys new microcode, we are making available an out of band update today, KB4078130, that specifically disables only the mitigation against CVE-2017-5715 – ‘Branch target injection vulnerability.’ In our testing this update has been found to prevent the behaviour described,” Microsoft wrote.

Microsoft says that update will cover Windows 7 (SP1), Windows 8.1, and all versions of Windows 10. The Redmond giant added that as of January 25, there have been no known cases that indicate the Spectre Variant 2 has been used to attack customers.

So far the update can only be installed manually. Download the update directly from here

However, Microsoft will release this update in the coming days/weeks to install automatically.
