Windows 10 February Update Available; Users Report Problems

Microsoft released the cumulative Windows 10 update that includes the February pack of bug and security fixes. Depending on the currently installed version of the operating system, we will download version 19042.804 (for Windows 10 20H2), 19041.804 (for W10 2004) or 18363.1377 (W10 1909).

We can download the update directly using Windows Update or by downloading the offline installer from the catalog on Microsoft's website. Since this is a smaller package, the developers responsible for the development of Windows 10 have focused on patching bugs instead of adding new features.

Key improvements in the February update for Windows 10

• Improved switching between apps using ALT TAB;
• Fixed ESENT bug 642;
• Fixed unnecessary deactivation of some devices after installing system patches;
• Fixed problem causing black screen after waking Windows 10 from hibernation;
• So called zero-day vulnerability in Win32k, which allowed for execution on unrecognized code by using visual interface to control e.g. printers and monitors
• 56 vulnerabilities in Windows were patched, including three related to the TCP/IP protocol.

However, before we rush to download the pack, we'd like to warn about possible inconveniences that may occur. Windows 10 is notorious for bugs popping up every time new patches are installed.

Two days ago, the optional update KB4598291 was made available, aimed at fixing issues reported by some users. However, the patch refused to install for random users. A brief investigation determined that we are dealing with the same bug that appeared during the May 2020 update. Some people also encountered problems with support for games that use DirectPlay technology (World of Warcraft is one such case).
