Are you facing the frustrating Windows 10 update error KB5034441? Don’t worry, we have got you covered. In this blog, we will explore effective methods to fix this issue and get your system back on track without risking your data. Let’s dive into the solutions and get your Windows 10 running smoothly again.

Understanding the Error

Issues with recovery partitions often cause the infamous Windows 10 update error KB5034441. This error can be a headache for users but fear not, we have solutions to tackle this head-on. Let’s start by understanding the root cause and implications of this error.

Certain computers may lack a sufficiently large recovery partition to execute this update successfully. Consequently, the WinRE update may encounter failure, leading to the error message, “KB5034441 update problem Error 0x80070643.”

The below picture shows a recovery partition that we will be expanding and we will check the size of the recovery partition at the end of the troubleshooting steps:

Steps To Fix Windows 10 Update KB5034441 update problem Error 0x80070643

First things first, we need to disable Windows recovery to address the failed update. Access the command prompt as an administrator and run a command to gather system information, including details about the hard disk. This step sets the stage for further troubleshooting. We will guide you through the necessary commands to disable Windows recovery securely and efficiently.

Your device needs to have the recovery partition positioned after the OS partition.

Verify this arrangement by following the steps outlined below:

  • Click on the Start Menu (Windows icon) in the bottom-left corner of your screen.
  • In the search box, type “cmd.”
  • Right-click on Command Prompt.
  • Select Run as administrator from the context menu.
  • To check the WinRE status, run reagentc /info. If the WinRE is installed, there should be a “Windows RE location” with a path to the WinRE directory. An example is, “Windows RE location: [file://%3f/GLOBALROOT/device/harddisk0/partition4/Recovery/WindowsRE]\\?\GLOBALROOT\device\harddisk0\partition4\Recovery\WindowsRE.” Here, the number after “harddisk” and “partition” is the index of the disk and partition WinRE is on.

Disabling Windows Recovery for Failed Update

To disable the WinRE, run reagentc /disable in the same command prompt window.

Resizing Partitions – The Safe Way

When dealing with partitions, it’s crucial to proceed with caution. We will walk you through the process of resizing the primary partition by 250 megabytes, ensuring that you are equipped to handle this task safely. We’ll cover how to use the diskpart tool to select and shrink the primary partition without risking the integrity of your system.

Now we need to shrink the Operating System partition and prepare the disk for a new recovery partition.

To shrink the OS, run diskpart

Run list disk

To select the OS disk, run sel disk<OS disk index as per your list>  This should be the same disk index as WinRE.

To check the partition under the OS disk and find the OS partition, run list part.

To select the OS partition, run sel part<OS partition index>, in my case, it is the Primary Partition 3 and we want some space from partition 3 which will be given to the recovery partition.

Run shrink desired=250 minimum=250

To select the WinRE partition which is our recovery partition, run sel part<WinRE partition index> and to delete the WinRE partition, run delete partition override.

If you have followed the above step properly then half of your work is done, You have successfully shrunk the OS partition and created space to expand the recovery partition.

Creating New Recovery Partition

In this section, we will delve into the commands required to create and format partitions, choose the appropriate file system, and enable Windows recovery. This detailed guide will equip you to navigate through the technicalities of partition management effectively.

Let’s check if the disk partition style is a GUID Partition Table (GPT) or a Master Boot Record (MBR). 

To do that, run the list disk command in the command prompt window. Check if there is an asterisk character (*) in the “Gpt” column.  If there is an asterisk character (*), then the drive is GPT. Otherwise, the drive is MBR as shown in the image below:

Once you get the information about the disk portion you need to run the following commands accordingly:

If your disk is GPT, run create partition primary id=de94bba4-06d1-4d40-a16a-bfd50179d6ac followed by the command gpt attributes =0x8000000000000001

If your disk is MBR, run create partition primary id=27

Since we have GPT partition we will be running create partition primary id=de94bba4-06d1-4d40-a16a-bfd50179d6ac followed by the command gpt attributes =0x8000000000000001

To format the partition, run format quick fs=ntfs label=”Windows RE tools”

We have successfully created a new recovery partition and formatted it using the NTFS file system. Now to exit from diskpart, run exit, and to re-enable WinRE, run reagentc /enable command.

Let’s exit the Command Prompt now and open the disk management utility to check the expanded size of the recovery partition after following the above steps.

Ensuring Successful Windows Update

Extending the Recovery Partition ensures a smooth Windows update experience without waiting for a patch from Microsoft. This practical workaround provides a reliable solution to evade the update error.

Now try running Windows updates and there should not be a problem installing Windows 10 Update KB5034441.


In conclusion, tackling the Windows 10 update error KB5034441 is well within your reach with the right guidance. By following the methods outlined in this blog, you can effectively troubleshoot the issue and restore the smooth functioning of your Windows 10 system. Empower yourself with the knowledge and tools to overcome this hurdle with confidence.
