patch tuesday

December Patch Tuesday brought two Windows 7 updates: KB4054518 and KB4054521.

Monthly Rollup KB4054518 features improvements and fixes that were a part of KB4051034 (the update was released in November), as well as three additional fixes and security improvements:

  • Addressed the issue where users of SQL Server Reporting Services could not use the scrollbar in a drop-down list.
  • Fixed additional issues with updated time zone information.
  • Added security updates to the Microsoft Scripting Engine and Windows Server.

Security update KB4054521 fixes time zone information issues and brings security updates to the Microsoft Scripting Engine and Windows Server.

Microsoft didn’t list any known issues for these two updates. We scoured Microsoft’s support forum and couldn’t find any bug reports. Indeed, it appears that these two updates are stable and don’t bring any issues of their own.

Download Windows 7 KB4054518 & KB4054521

You can download KB4054518 automatically via Windows Update. You can also download the standalone update package from the Microsoft Update Catalog website.

The same is valid for KB4054521. You can download and install it automatically via Windows Update or get the standalone package from Microsoft’s Update Catalog.

Installing the latest Windows 7 updates on your computer is essential to keeping it save from cyber threats. As a quick reminder, the spread of the ransomware attacks from a few months ago was facilitated by Windows 7.

So, protect your PC and install the December Patch Tuesday updates as soon as possible to stay one step ahead of hackers.
