Microsoft has released a new emergency update KB4078130 for Windows 7, Windows 8.1 and windows 10 devices powered by Intel chips. This update fixes the Reboot issues faced by Intel devices because of the earlier released official Specter fixes.
Due to these issues, Intel on January 22nd recommended that customers stop deploying the current Specter fix on impacted processors while they perform additional testing on the updated solution.
Now, with KB4078130, Microsoft has provided a way to disable the Specter update and fix the reboot issue.
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 behavior described. For the full list of devices, see Intel’s microcode revision guidance. This update covers Windows 7 (SP1), Windows 8.1, and all versions of Windows 10, for client and server.
If you are running an impacted device, this update can be applied by downloading it from the Microsoft Update Catalog website.
