Devices attempting to install the January 2024 Windows Recovery Environment update ( KB5034441) might display an error related to the size of the Recovery Environment’s partition. The Windows Recovery Environment (WinRE) is used to repair or recover from issues affecting Windows.

Resulting from this error, the following message might be displayed.

  • ​”0x80070643 – ERROR_INSTALL_FAILURE”

Affected platforms:

  • ​Client: Windows 11, version 21H2; Windows 10, version 22H2; Windows 10, version 21H2
  • ​Server: Windows Server 2022


The problem happens due to a lack of free space in the Windows RE partition. The update failed to stage WinRE servicing operation due to insufficient disk space in WinRE partition.


The KB5034441 update services your Winre.wim image and it required approximately 55 MB of free disk space on our test systems. If you’re using the Windows-default winre.wim, ensure that the Recovery partition’s size is 700 to 750 MB. If your Recovery partition’s size is smaller (e.g., 550 MB or something), please resize it to 700 to 750 MB.

Note: For OEM-supplied winre.wim (which has additional drivers and packages), ensure the Recovery partition’s size is atleast 100 MB more than the size of the custom wim.

Option 1: Resize the partition using DiskPart

The instructions for resizing your Recovery partition are mentioned in the Microsoft article below.

KB5028997: Instructions to manually resize your partition to install the WinRE update – Microsoft Support

Note: The above MS article works only if your Recovery partition is situated next to (i.e., right side) the OS partition. You can check the disk layout by opening Disk Management.

Option 2: Resize the partition using third-party tools

Alternatively, you can try MiniTool Partition Wizard or EaseUS software to increase the size of the Recovery partition.

Option 3: Hide the KB5034441 Update

If you don’t use Bitlocker and want to skip the KB5034441 security update, you may use Microsoft’s Show/Hide Updates tool to hide the KB5034441 update temporarily.

The tool can be downloaded from the following link:


Select the KB5034441 update and hide it.

Windows Recovery Environment servicing failed.

To help you recover from this failure, please follow Instructions to manually resize your partition to install the WinRE update.
