On January 3, 2018, Microsoft began to release its monthly Security Bulletin early due to the newly revealed CPU security flaws. Microsoft's January 2018 monthly update implements new requirements to ensure that security and anti-virus software is compatible.

Information has recently been released about a set of vulnerabilities commonly referred to as Meltdown and Spectre that could be exploited at a hardware (CPU) layer on multiple operating systems including Microsoft Windows, Linux, and Apple macOS.

Customers running any version of Trend Micro Security will require a new Microsoft Windows registry key to allow the Windows Update to automatically occur. Microsoft is not providing a tool to add this registry key, therefore Trend Micro is offering several options, to ensure customers are able to receive the January Microsoft patches as quickly possible in conjunction with Trend Micro security software deployment.
