KB4540673 fixes update process

The March Patch Tuesday Updates are finally here, and Microsoft has prepared plenty of new security patches and feature updates for users to try out. Cumulative updates are available for all versions of Windows 10, and installing them is done in the same way as typical updates.

Third-party programs will no longer interfere with OS updates

One of the highlights of this round of patches is a cumulative update released for Windows 10 v1909 and v1903 users called KB4540673 

As a general idea, KB4540673 contains security updates to Windows App Platform and Frameworks, Windows Media, Windows Silicon Platform, and more.

However, what makes this update stand out is a fix for an issue that many users have been complaining about.

More precisely, KB4540673 addresses an issue that prevents certain users from upgrading the OS because of corrupted third-party assemblies.

As you can imagine, having certain programs installed that had nothing to do with Microsoft could cause interferences with the OS update process. This included slow downloads, installations getting stuck halfway through, error messages, and more.

However, KB4540673 supposedly fixes all that, and now users can enjoy a smoother update experience.


Get KB4540673 as soon as possible

Those that run Windows 10 version 1909 and 1903 can get the latest Patch Tuesday updates via the typical methods you would get any other type of update.

This means using methods like the Windows Update Catalog, using the Windows ServerUpdate Services (WSUS), or using the built-in Windows Update feature.

Keep in mind that Patch Tuesday Updates are generally very important, as they usually contain major feature improvements and security patches.

Note: It is important that you always have a backup of all of your data before performing a big set of updates like the ones on Patch Tuesday.
