Since this is a cumulative update, if you have installed the previous updates, only the new fixes will be applied to your PC. With these improvements, the release also has a few known issues.
Known Issues
An issue with the standalone (clean) installation of Windows 10 with this update causes Microsoft Edge Legacy to be removed. However, the new Chromium-based Edge is not replacing it. This occurs only when Windows has a custom offline media or 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. Another issue that Microsoft highlights is that any recovery discs created after installing these updates using the Backup and Restore (Windows 7) feature may not work. Microsoft also adds that the recovery discs created before installing the mentioned updates are not affected. However, there is currently no fix for the problem. Microsoft is currently working on this issue and intends to fix it in a future flight. This issue applies not only to this release, but also to any updates released after the Windows 11 January 11, 2022 update. The issues listed above have been present with Windows 10 for some time now. However, a new issue reported by Microsoft is that the Snip & Sketch app might occasionally fail to capture a screenshot and not open using the keyboard shortcut (Windows Key + Shift + S). At the moment, there is no solution to this problem. If you are comfortable working with these problems, continue on down to learn how to install this update.
