What’s New in Windows 10 Cumulative Update KB4494441

The May 2019 Patch Tuesday rollout brings a new pack of cumulative updates for Windows 10, and the October 2018 Update, or version 1809, is getting its own release.

Windows 10 October 2018 Update is the latest stable version of the operating system at this point, with its first successor projected to go live later this month.

The adoption of the October 2018 Update has so far increased rather slowly, so at this point it’s running on approximately 30 percent of all Windows 10 devices. In other words, there’s a chance some users might skip it entirely and move directly to the May 2019 Update coming in just a few weeks.

As for what’s new in cumulative update KB4494441 the focus is obviously on resolving security vulnerabilities in Windows 10, but also in Microsoft Edge, Internet Explorer, the Windows Scripting engine, and other modules. You can check out the full changelog in the box after the jump.

But as per Microsoft’s typical approach, non-security fixes are included as well, and these are more than welcome given the further refine the experience with the OS.

For example, cumulative update KB4494441 fixes a problem with certain fonts breaking down Microsoft Excel, while also introducing additional Spectre Variant 2 mitigations. Microsoft explains the following:

“Enables “Retpoline” by default if Spectre Variant 2 (CVE-2017-5715) is enabled. Make sure previous OS protections against the Spectre Variant 2 vulnerability are enabled using the registry settings described in the Windows Client and Windows Server articles. (These registry settings are enabled by default for Windows Client OS editions, but disabled by default for Windows Server OS editions).”

While Microsoft recommends users to install this update as soon as possible, some might just want to wait given that cumulative updates have previously caused issues or failed to install. Right now, however, there are no reports of failed installs.

It remains to be seen how reliable this cumulative update truly is, so let us know in the comment box below should you run into any issues when installing it.
