Microsoft's Windows 10 WinRE Update Glitch: Error 0x80070643 Explained

Over a year later, Microsoft is still grappling with WinRE update issues. The recent Windows 10 KB5057589 update has brought the error 0x80070643 to light. This article explores the problem and offers solutions.

Windows 10 KB5057589 and Error 0x80070643

Released April 8, 2025, KB5057589 aimed to improve Windows Recovery Environment (WinRE) for Windows 10 21H2 and 22H2. It requires 250MB of free space on your recovery partition. However, many users report encountering error 0x80070643 – ERROR_INSTALL_FAILURE even after successful installation. This issue also affects Windows Server 2022 users installing KB5057588. This isn't a new problem; similar errors occurred with KB5034441 in 2024.

Resolving the Issue?

First, verify your recovery partition has at least 250MB free space. If not, resize it using the Command Prompt (refer to previous tutorials for instructions). However, even with sufficient space, the error may persist.

Microsoft's Recommendation: Ignore the Error

Microsoft currently advises ignoring the error. They state the message is inaccurate and doesn't affect system updates or functionality. The error often appears if another WinRE update is pending a reboot; a restart usually resolves the issue. The error message may remain visible in Windows Update until the next daily scan.

The Windows 11 Alternative

With Windows 10's end-of-support approaching (October 14, 2025), security updates and support will diminish. Upgrading to Windows 11 is a viable alternative, offering enhanced features and security.

Before upgrading, always back up your data. MiniTool ShadowMaker is a recommended backup solution for Windows 11/10/8/7, supporting file, folder, partition, disk, and system backups.

Conclusion

Error 0x80070643 after installing KB5057589 is primarily a Windows Update anomaly, not a critical system failure. Ignoring it is often sufficient. However, considering Windows 10's impending end-of-life, upgrading to Windows 11 is strongly recommended. The choice ultimately depends on your individual needs and preferences.
