When upgrading to or installing Windows 11 24H2, some users may encounter the installation error 0x80070001 – 0x4002f, which can prevent the successful completion of the update process. This error typically signals a failure in the Windows Update process or a corruption issue with system files that are required to install or upgrade to the new version.

If you’re experiencing this issue, don’t worry. In this guide, we’ll cover the potential causes behind the 0x80070001 – 0x4002f error and walk you through the steps to fix it.


What Is the Error Code 0x80070001 – 0x4002f?

The 0x80070001 – 0x4002f error code is a common Windows Update problem that can occur during the installation of updates, particularly when upgrading to major versions like Windows 11 24H2.

This error may be triggered by several factors, including:

  • Corrupt system files or missing components essential for the update.
  • Insufficient disk space to complete the installation.
  • Faulty Windows Update components that prevent the system from applying the upgrade.
  • Third-party software conflicts, such as antivirus programs that block the update process.

How to Fix Windows 11 24H2 Error Code 0x80070001 – 0x4002f

Here are the detailed steps you can follow to resolve this issue and successfully complete your Windows 11 upgrade or installation.


1. Run the Windows Update Troubleshooter

Windows comes with a built-in troubleshooter that can automatically detect and resolve many update-related issues. Here’s how to run it:

  1. Press Win + I to open Settings.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Under Most frequent, click Run next to Windows Update.
  4. Let the troubleshooter scan for issues. Follow the on-screen instructions to apply any fixes it suggests.

Once the troubleshooter completes its scan, try running the update again to see if the issue is resolved.


2. Check for Sufficient Disk Space

One common reason for update errors is a lack of free space on your system drive (usually C: drive). Windows 11 requires a significant amount of free space for installation, especially when upgrading to a major version.

  1. Open File Explorer and right-click on C: drive.
  2. Select Properties.
  3. Under the General tab, check the Used space and Free space.
  4. If there isn’t enough space (at least 20 GB is recommended), delete unnecessary files or move them to an external drive to free up space.

3. Clear Windows Update Cache

Sometimes, corrupt or incomplete files in the Windows Update cache can trigger errors during installation. Clearing the cache might resolve the issue.

To do this:

  1. Press Win + R, type services.msc, and hit Enter.
  2. Scroll down and locate Windows Update in the list of services.
  3. Right-click on Windows Update and select Stop.
  4. Navigate to C:\Windows\SoftwareDistribution\Download and delete all files in the folder.
  5. Return to services.msc, right-click on Windows Update, and select Start to restart the service.
  6. Retry the update.

4. Use the Windows Update Assistant

If standard troubleshooting doesn’t work, using the Windows Update Assistant can help you upgrade your system to Windows 11 24H2 manually:

  1. Visit the official Windows 11 Download page.
  2. Under Windows 11 Installation Assistant, click Download now.
  3. Run the downloaded tool and follow the prompts to start the update process.

The Windows Update Assistant will attempt to install the update while bypassing any problematic components in the regular Windows Update process.


5. Repair System Files with SFC and DISM

Corrupt or missing system files can also prevent updates from completing successfully. Use the System File Checker (SFC) and Deployment Imaging Service and Management Tool (DISM) to repair these files:

  1. Press Win + X and select Command Prompt (Admin) or Windows PowerShell (Admin).
  2. Type the following command and press Enter:
    sfc /scannow
    
  3. Wait for the process to complete. If any issues are found, SFC will attempt to fix them.
  4. After SFC finishes, type the following DISM commands one by one, pressing Enter after each:
    DISM /Online /Cleanup-Image /RestoreHealth
    DISM /Online /Cleanup-Image /ScanHealth
    
  5. Restart your PC after both tools finish running.

6. Disable Third-Party Antivirus or Security Software

Some antivirus or security software can interfere with Windows updates and cause errors like 0x80070001 – 0x4002f. Disable your antivirus temporarily and attempt to run the update again:

  1. Open your antivirus program.
  2. Disable real-time protection or completely turn off the program (depending on the software).
  3. Retry the update.

If the update is successful after disabling the antivirus, make sure to re-enable it once the installation is complete.


7. Perform a Clean Boot

A clean boot can help rule out third-party services or startup programs that might be causing conflicts with the update process. To perform a clean boot:

  1. Press Win + R, type msconfig, and hit Enter.
  2. In the System Configuration window, go to the Services tab.
  3. Check the box that says Hide all Microsoft services, then click Disable all.
  4. Go to the Startup tab and click Open Task Manager.
  5. In Task Manager, disable all startup programs.
  6. Close Task Manager and click OK in the System Configuration window.
  7. Restart your PC and try the update again.

8. Perform an In-Place Upgrade

If none of the above solutions work, performing an in-place upgrade can repair or reinstall Windows 11 without affecting your personal files.

  1. Download the Windows 11 ISO from the official Microsoft website.
  2. Mount the ISO file by double-clicking it.
  3. Run setup.exe from the mounted drive.
  4. Follow the on-screen instructions to perform an in-place upgrade.
