Microsoft Updates KB5034440 and KB5034441 Logs, Helps Users Fix 0x80070643 Error

TapTechNews July 11th news, Microsoft has updated the KB5034440 (for Windows 11) and KB5034441 (for Windows 10) update support logs again today, releasing detailed operation guides to help users fix the 0x80070643 error that occurred in January this year.

TapTechNews briefly reviews the sequence of events as follows:

Microsoft released the KB5034440 update for Windows 11 and the KB5034441 update for Windows 10 in January this year, but users reported the 0x80070643 error after installation.

Microsoft announced in January that this problem was caused by insufficient size of the Windows Recovery Partition (WinRE).

Microsoft released a PowerShell script in March and added that users without a WinRE partition do not need to update.

Microsoft acknowledged in May that this problem cannot be automatically repaired and requires manual update by users.

Microsoft has now updated the log again, adding important notes and revising how to increase the WinRE recovery partition to 250MB of available space in the Notes:

If the Windows Recovery Environment (WinRE) meets any of the following conditions, this update will not be provided:

If there is not enough available space in the WinRE recovery partition.

If the WinRE recovery partition is manually updated during an in-use process, add the update package to WindowsRE and it is already up to date.

If the version of the WinRE image is greater than or equal to version 10.0.22000.2710. To determine the version of the WinRE image, check the WinREVersion registry value at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion.

If the running computer does not have a WinRE recovery partition. To verify if WinRE is enabled, run the following command in an elevated command prompt: reagentc/info. If WinRE is enabled, the WindowsRE status will be displayed in the output with a value of Enabled. In this scenario, this update may be required.
