Microsoft has released a security update on January 3 that mitigates security issue in several modern CPUs. This update comes with new requirements that might break compatibility with specialized applications such as security products.
As per Microsoft’s requirements, security vendors are required to validate compatibility with the new update before accepting it for installation. Here at Bitdefender we take security seriously and we are now in the process of running extensive compatibility tests with all supported operating systems.
As soon as we validate the January 3 security fix against all our supported products, we will deliver an automatic update that enables the installation of the fix.
For more information about the January 3 security update, please check this knowledge base entry on Microsoft’s website. This document will be updated with new information as we validate the updates against our consumer and business products.
