Windows 10 KB5013942 (21H2, 21H1) is out

Windows 10 KB5013942

Windows 11 KB5013942 has been released as Microsoft has started pushing May 2022 Patch Tuesday updates. This release doesn’t come with tons of new features, but there are plenty of bug fixes for everyone. Direct download links for Windows 10 KB5012599 offline installers are also available for those who are unable to install patches via WU.

KB5013942 is a security update and it is being pushed as part of the May 2022 Patch Tuesday cycle. Since Windows 10 is now on the backburner with Microsoft’s focus entirely on Windows 11, there are no major changes in this particular Patch Tuesday release. Of course, there are those 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 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 folks when they sign in and sign out has been fixed. Another bug where the Microsoft OneDrive file loses focus after you rename it and press the Enter key has been patched in this release. Likewise, Microsoft is also improving News and Interest panel by fixing a few bugs here and there.

If you’re on 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.

If you check for updates, you’ll see either of the update alerts depending on the version of Windows 10:

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


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