Windows 10 KB5013942 (21H2, 21H1) is out – here’s everything new

Written by admin

Windows 11 KB5013942 was released because Microsoft started pushing updates for the patch Tuesday of May 2022. This release does not contain many new features, but there are enough bug fixes for everyone. Direct download links for offline installers for Windows 10 KB5013942 are also available for those unable to install patches through WU.

KB5013942 is a security update and is being pushed as part of the May 2022 Patch Tuesday cycle. Since Windows 10 is now on the back burner with Microsoft’s focus entirely on Windows 11, there are no major changes in this particular Patch Tuesday release . Of course there are the usual bug fixes and security improvements.

The previous update enabled support for Windows Search Highlights and some other improvements. On the other hand, this release doesn’t contain any noticeable change, but the tech giant says it has fixed an issue that causes Internet Explorer to stop working when you copy and paste the text.

A critical bug that causes a black screen for some people when logging in and out has been fixed. Another bug where the Microsoft OneDrive file loses focus after you rename it and hit the Enter key has been patched in this release. Likewise, Microsoft is also improving the News and Interests panel by fixing a few bugs here and there.

If you are using Windows 11, Microsoft has released a cumulative update for your device and most of the changes are identical. That’s because Windows 11 is apparently built on top of Windows 10, so most of the fixes and bugs are shared between the two operating systems.

When you check for updates, you will see one of the update warnings depending on the version of Windows 10:

2022-05 Cumulative Update for Windows 10 Version 21H2 for x64-based Systems (KB5013942)

Or

2022-05 Cumulative Update for Windows 10 Version 21H1 for x64-based Systems (KB5013942)

Microsoft is offering the security update through Windows Update and Windows Update for Business, but it is still possible to manually download and install the patch from the Microsoft Update Catalog.

The Microsoft Update Catalog linked above provides direct access to the offline installation file (.msi), so you can double tap the link and start the download. It’s also worth noting that the company has made changes to the update catalog to support HTTPS requests, meaning you can now simply tap the link to start the download.
