Quick Note Before You Begin

Before diving into fixes, make sure of the following:

  • Your internet connection is stable. Interrupted downloads can cause errors.
  • You have enough free space on your hard drive (at least 8-10 GB recommended) to create installation media or upgrade.
  • You are running the Media Creation Tool with administrator rights. Right-click the tool and select Run as administrator.
  • Temporarily disable any antivirus or firewall that might block the tool’s operations.

Step 1: Restart Your PC and Try Again

Sometimes, temporary glitches cause errors like 0x8007043c-0x90017. Restarting your computer can clear these minor issues.

  1. Save any open work and close all programs.
  2. Click the Start button, select the Power icon, then click Restart.
  3. Once the PC restarts, run the Media Creation Tool again as an administrator.

This simple restart often fixes problems by resetting system processes that might interfere with the tool.

Step 2: Run Windows Update Troubleshooter

The Media Creation Tool relies on Windows Update components to work properly. If these components have issues, you may get errors.

  1. Press Windows + I to open Settings.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Windows Update and click Run.
  4. Follow the on-screen instructions to let Windows detect and fix update problems.
  5. After the troubleshooter finishes, restart your computer and try the Media Creation Tool again.

This step helps repair any broken update files or services that might cause the error.

Step 3: Clear the SoftwareDistribution Folder

The SoftwareDistribution folder stores temporary update files. Sometimes, these files can get corrupted and block the Media Creation Tool.

Clearing this folder forces Windows to re-download fresh update files.

  1. Press Windows + S, type cmd, right-click Command Prompt, and select Run as administrator.
  2. In the command window, type the following commands one by one and press Enter after each:
net stop wuauserv
net stop bits
  1. Now, open File Explorer and navigate to C:WindowsSoftwareDistribution.
  2. Delete all contents inside this folder (select all files and folders, then press Delete).
  3. Return to the Command Prompt and type:
net start wuauserv
net start bits

Close the Command Prompt and try running the Media Creation Tool again.

Clearing this folder solves problems caused by corrupted updates or incomplete downloads.

Step 4: Temporarily Disable Antivirus and Firewall

Antivirus programs or firewall settings may mistakenly block the Media Creation Tool from accessing necessary resources.

To check if this is the cause:

  • Open your antivirus software and look for options to temporarily disable protection.
  • For Windows Firewall, press Windows + I, go to Privacy & security > Windows Security > Firewall & network protection.
  • Choose your active network and turn off the firewall temporarily.

After disabling protection, try running the Media Creation Tool again. Remember to re-enable your antivirus and firewall afterward to keep your PC safe.

Step 5: Use the Media Creation Tool in Clean Boot Mode

Clean Boot starts Windows with only essential services running. This prevents third-party software conflicts that may cause errors.

  1. Press Windows + R, type msconfig, and press Enter.
  2. In the System Configuration window, go to the Services tab.
  3. Check Hide all Microsoft services to avoid disabling essential system services.
  4. Click Disable all to turn off third-party services.
  5. Go to the Startup tab and click Open Task Manager.
  6. Disable all startup items listed by right-clicking each and selecting Disable.
  7. Close Task Manager and click OK on the System Configuration window.
  8. Restart your computer.
  9. Try running the Media Creation Tool again.
  10. To return to normal startup, open msconfig again and choose Normal startup.

This helps identify if background programs are causing the error.

Step 6: Download a Fresh Copy of Media Creation Tool

Your current Media Creation Tool file might be corrupted or outdated. Downloading a new copy ensures you have the latest, clean version.

  1. Go to the official Microsoft Windows 11 download page: https://www.microsoft.com/software-download/windows11
  2. Click on Download now under the Media Creation Tool section.
  3. Save the file and run it as administrator.

Using the latest tool helps avoid bugs fixed in newer versions.
