Microsoft has released KB5010342 for Windows 10 versions 21H2, 21H1, and 20H2. Since Windows 10 versions 2004 through 21H2 share the same core, the same update can be applied to all of them. However, version 2004 had reached the end of service on December 14, 2021, therefore the update is not available for the said Windows version. This update does not bring any new features to the operating system. However, it does fix a number of security vulnerabilities, including one zero-day vulnerability. The details about the security fixes can be found in this post by Microsoft.

Let’s continue to see what this update has to offer and whether it has any significant issues, and then proceed to how you can install it.
Fixes and Improvements
This update includes quality improvements for the Servicing Stack (SSU), which is responsible for installing the Windows updates. These improvements ensure that the user has a smooth experience while installing these updates. Installing this update will upgrade the SSU’s build to 1904x.1525. Furthermore, an issue with Lightweight Directory Access Protocol (LDAP) which causes it to fail if the operating contains SamAccountName and UserAccountControl attributes, has been fixed. Users usually encountered this error with the following statement: With these improvements, there are several issues with the release as well.
Known Issues
An issue with the standalone (clean) installation of Windows 10 with this update is causing Microsoft Edge Legacy to be removed. However, it is not being replaced by the new Chromium-based Edge. This occurs only when Windows has a custom offline media or an ISO image installed that does not include the 29th March 2021 SSU update. Microsoft suggests that you either install the March SSU update through slipstreaming or simply update an existing OS through Windows Update, so you will not be facing this issue. Alternatively, you can simply download and install the new Microsoft Edge if you have already encountered this problem. Another issue that users might face with this update is that they are unable to install it entirely. This may be because of a previously installed update KB5003690. If that is the case, you can find a workaround for it here in Microsoft’s post. Users may also see an error message “Your credentials did not work. The credentials that were used to connect to (device name) did not work. Please enter new credentials” when connecting to devices in an untrusted domain using Remote Desktop while using smart card authentication. Microsoft has found a temporary fix around the issue which you can find here. These issues have been around for Windows 10 for quite some time now. However, Microsoft has not been successful at fixing them as of yet.
