A new bug has emerged on Windows 10 machines, causing a stir among users following a significant update. Microsoft, however, is urging users to remain calm and not to worry excessively about the situation. Windows updates have long been known for their unpredictability, often leading to unforeseen complications. The latest update, KB5057589, which pertains to the Windows 10 21H2 and 22H2 April update, has introduced a peculiar issue that might cause some anxiety among users. This update began rolling out on April 8 and is primarily focused on enhancing the Windows Recovery Environment (WinRE) by applying a Safe OS Dynamic update to improve recovery features.
Understanding the Bug
Despite Microsoft’s intentions, a segment of users has reported encountering the 0x80070643 error during the update installation, accompanied by an “ERRORINSTALLFAILURE” message. This error could imply that one of Windows 10’s crucial tools for data protection is failing to install. For those concerned about the potential for an unbootable system, Microsoft advises a more relaxed approach. In the official support documentation for the update, the company acknowledges the error with WinRE alongside other priority issues. While some of these issues have been resolved, such as problems with USB printers and dual Windows-Linux boot setups, Microsoft is actively working on a fix.
In the meantime, the company suggests reverting to a classic IT solution: simply turning the machine off and on again. This age-old remedy may seem simplistic, but it often works wonders. Microsoft reassures users that the 0x80070643 – ERRORINSTALLFAILURE message is largely inaccurate and will not hinder the functionality of Windows Repair. This error typically arises when another update is pending a reboot, and the update should show as complete following a successful restart. If the restart does not resolve the issue, Microsoft encourages users to remain patient, as the support documentation suggests that time may indeed heal this particular Windows 10 wound.
It’s important to note that Windows Update may continue to display the update as failed, but after the next daily scan, the message should automatically clear. As Windows 10 approaches its end-of-support date on October 14, 2025, Microsoft has recently published a checklist for users still operating on this version, subtly nudging them to consider upgrading their systems.
After the end-of-support date, Microsoft will cease providing security patches, features, or technical assistance for Windows 10 machines, unless users opt into the Extended Security Updates program, which offers an additional year of support for a fee. Meanwhile, Windows 11 continues to evolve, introducing a plethora of new features, including advanced generative AI capabilities. One of the latest enhancements allows Copilot, Microsoft’s AI assistant, to read screens and interact with applications, provided users grant permission.
Windows 11 is actively supported with regular updates that include important bug fixes and security patches. A forthcoming update promises a revamped Start menu, making it larger and more streamlined. Additionally, users will soon have the option to sign in without a password, while the notorious Blue Screen of Death is set to receive a fresh new look.
