The 0x80070643 Error During the Update Installation

During the installation of the KB5034441 update, many users encountered error 0x80070643. Microsoft identified that the main cause of this problem lies in the size of the Windows Recovery Environment (WinRE) partition. Normally, this partition is about 500MB in size and contains the necessary tools to repair the operating system. The KB5034441 update, requiring an updated and larger recovery environment, exhausts the available space, leading to the error and blocking the installation.

Microsoft’s Proposed Solution for the 0x80070643 Error

To solve this issue, Microsoft has suggested users to manually shrink the main disk partition by 250MB to free up enough space to expand the recovery partition. However, this solution can be complicated, especially for less experienced users. Modifying partitions, if done incorrectly, can lead to data loss, especially if there is no backup.

Conclusions and Advice for Users

Considering the complexity and potential risks associated with Microsoft’s proposed solution, our advice is to refrain from making autonomous changes to disk partitions. It is preferable to wait for an automatic fix from Microsoft that can solve the problem without exposing you to unnecessary risks.In the meantime, it is essential to maintain a regular backup of your data to prevent any potential losses. Data security and integrity should always be a priority, especially when dealing with operating system updates that can directly affect the functioning of your computer.
