Manual Fixes for the 0x80070643 Error

Conquering the 0x80070643 Error: Two Manual Fix Options

In a surprising twist, Microsoft has decided not to roll out an automatic fix for the 0x80070643 error. So, the responsibility now falls on users to roll up their sleeves and manually tackle the issue of not enough space in the WinRE partition. But fear not, because you’ve got two main ways to deal with this hiccup:

Option 1: Resize the WinRE Partition Yourself

This method involves using a tool called Disk Management that’s already built into Windows. With it, you can physically adjust the size of the WinRE partition to make more Space.

While this approach is doable for most folks, it does require a bit of familiarity with disk management tools and a careful eye for following the steps.

Option 2: Get Technical with a Script to Extend the WinRE Partition

Now, if you’re someone who’s comfortable diving into the nitty-gritty of command lines and considers yourself pretty tech-savvy, this option might be right up your alley.

It involves getting your hands on a script provided by Microsoft that automates the process of extending the WinRE partition, sparing you from having to manually do all the legwork.

Option 1: Manually Resizing the WinRE Partition (Detailed Steps)

Important Note: Before proceeding, it’s crucial to back up any critical data on your system. While the resizing process is generally safe, unforeseen complications can always occur.

Here’s a step-by-step guide to manually resizing the WinRE partition using Disk Management:

Open Disk Management:

Search for “Disk Management” in the Windows Start menu and open the application.

Locate the WinRE Partition:

  • In the Disk Management window, identify your primary hard drive (usually labeled Disk 0).
  • Look for a small partition labeled “Reserved” or “Recovery” with a size typically between 100 MB and 500 MB. This is your WinRE partition.

Identify a Shrinkable Partition:

  • Right-click on a partition with sufficient free space (usually the C: drive) and select “Shrink Volume.”
  • In the “Shrink” window, enter a value for the amount of space you want to shrink from the partition (e.g., 500 MB). Ensure this value is enough to comfortably accommodate the WinRE partition expansion.
  • Click “Shrink” to proceed.

Extend the WinRE Partition:

  • Right-click on the WinRE partition and select “Extend Volume.”
  • In the “Extend Volume Wizard,” click “Next” to continue.
  • Select the unallocated space created by shrinking another partition in the previous step and click “Next.”
  • Review the summary and click “Finish” to extend the WinRE partition with the allocated space.

Restart Your System:

Once the resizing process is complete, restart your computer for the changes to take effect.

Caution: Remember, manipulating disk partitions can have unintended consequences. Double-check your drive selections and ensure you have chosen the correct partitions before proceeding with any actions.

Option 2: Using a Script to Extend the WinRE Partition (For Advanced Users)

If you’re a comfortable user with command lines, this option might be a quicker solution. However, it requires a bit more technical know-how compared to the manual resizing method.

Here’s what you’ll need:

  • Administrative privileges on your Windows system.
  • A basic understanding of using Command Prompt with administrator rights.

Important Note: While Microsoft provides the script, using it incorrectly can lead to unintended consequences. Proceed with caution and only if you feel comfortable with command lines.

Microsoft Script for Extending WinRE Partition:

Microsoft offers a script specifically designed to extend the WinRE partition. You can access the script and detailed instructions on its official documentation page.

Following these steps carefully will guide you through utilizing the script:

Download the Script:

Visit the Microsoft documentation page linked above and download the script file (typically a .ps1 file).

Run Command Prompt as Administrator:

  • Search for “Command Prompt” in the Windows Start menu.
  • Right-click on “Command Prompt” and select “Run as administrator.”

Navigate to the Script Location:

In the Command Prompt window, use the cd command to navigate to the directory where you downloaded the script file. For example, if you downloaded it to your Downloads folder, you would type:cd \Users\<username>\Downloads (Replace <username> with your actual Windows username)

Run the Script:

Once you’re in the correct directory, type the following command and press Enter to execute the script:.\Expand-WinRE.ps1

Review the Script Output:

  • The script will analyze your system and display information about your partitions. It will then attempt to extend the WinRE partition using the available unallocated space.
  • Carefully review the script’s output to ensure the process completes successfully.

    Restart Your System:

    After running the script, regardless of which method you chose (manual or script), it’s crucial to restart your computer. This allows the system to apply the changes made to the WinRE partition and potentially resolve the 0x80070643 error during future updates.

    Additional Considerations for Advanced Users:

    The Microsoft documentation page offers more advanced options and troubleshooting steps for users comfortable with manipulating partitions through DISM (Deployment Image Servicing and Management) tool. However, these methods are beyond the scope of this guide and should only be attempted by experienced users who understand the potential risks involved.

    Alternative Solutions and Preventative Measures

    Beyond Manual Fixes: Alternative Solutions to Consider

    While the manual resizing methods can effectively address the 0x80070643 error, they might not be suitable for everyone. Here are a few alternative solutions you can explore if the manual fixes seem daunting:

    • Run the Windows Update troubleshooter: This built-in Windows tool can sometimes identify and rectify issues preventing successful updates. While it may not directly target the 0x80070643 error in all cases, it’s worth a try as a first step.
    • Temporarily disable antivirus software (with caution): In rare instances, antivirus software can interfere with the update process. Use this approach as a last resort and only after temporarily disabling any real-time scanning features. Remember to re-enable your antivirus software immediately after attempting the update.
    • Manually download and install the update (for experienced users): If you’re comfortable with navigating Microsoft’s Update Catalog, you can download the specific update causing the error and install it manually. This method requires knowledge of your system architecture (32-bit or 64-bit) and finding the exact update version.

    Important Note: These alternative solutions are not guaranteed fixes for the 0x80070643 error. However, they might be worth trying before diving into manual partition manipulation.

    Preventing Future 0x80070643 Errors (Tips for Maintaining Disk Space)

    Here are some proactive measures you can take to minimize the chances of encountering the 0x80070643 error in the future:

    • Regularly clean up temporary files and unnecessary programs: Over time, temporary files and unused programs can accumulate, eating into valuable disk space. Utilize the built-in Disk Cleanup tool or manually identify and remove unnecessary files to free up space.
