Windows 10 is a great operating system, and it got even better after the latest updates. Unfortunately, installing Windows 10 isn’t always easy and users reported that Windows 10 couldn’t be installed on their PC.

How to fix the “Windows installation has failed” error?

Solution 1 – Run Windows Update troubleshooter

If you’re downloading the latest build of Windows 10 via Windows Update, you might encounter this error. To fix it, run the Windows Update troubleshooter by following these steps:

  1. Press Windows Key + S and enter troubleshooting. Select Troubleshooting from the menu.
  2. Choose View all from the menu on the left.
  3. Select Windows Update.
  4. Click Next to start the wizard.

After the wizard completes the scan and fixes the errors, you should be able to install the new build of Windows 10.

Solution 2 – Install Windows 10 using Media Creation Tool

You might want to try using Media Creation Tool to download the new build. To complete this process you’ll need an empty USB flash drive. Once you download Windows 10 ISO, you can create a bootable installation media using the Windows Media Creation tool. Now you just need to start the installation from the USB flash drive.

Solution 3 – Change registry values

You might be able to fix this problem simply by changing one value in your registry. We have to mention that changing the registry can lead to certain issues if you’re not careful, so it might be a good idea to create a backup of your registry in case anything goes wrong.

To edit the registry follow these steps:

  1. Press Windows Key + R and enter regedit. Press Enter or click OK.
  2. Go to the HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControl key in the left pane.
  3. In right pane locate PortableOperatingSystem value and double click it to open its properties.
  4. Change Value data from 1 to 0. Some users claim that changing the value from 0 to 1 also fixes the issue, so you might want to try that as well.
  5. Close Registry Editor, restart your PC and check if the problem is resolved.

Solution 4 – Turn off your firewall and antivirus

If you’re getting error code 8024402C while trying to download the latest Windows 10 build, you might want to temporarily disable your antivirus and firewall.

These tools can sometimes interfere with Windows Update. In some cases, you might even have to delete your third-party antivirus and firewall. You can also use a dedicated uninstaller tool to get the job done.

We also have to mention that you’ll have to disable Windows Firewall to fix this problem, and you can do that by following these steps:

  1. Press Windows Key + S and enter firewall. Select Windows Firewall from the list.

  3. Change Account type from Standard to Administrator. Click OK to save changes.
