The problem is usually accompanied by the Error Code 0x80070426.

What is the Error Code 0x80070426?

You may have noticed that when you upgraded to Windows 10, Windows Defender failed to replace Microsoft Security Essentials. Basically, the two antivirus programs are running on the new operating system.

Perhaps, you tried launching Windows Defender, but it failed to start. As such, you turned to Microsoft Security Essentials. However, when you opened it, you noticed that the Virus Protection and Spyware & Unwanted Software Protection features were disabled. So, you tried to switch them on. Unfortunately, a Microsoft Security Client dialog with the following error message showed up:

“An error has occurred in program initialization. If this problem continues, contact your System Administrator. Error Code: 0x80070426.”

To get rid of the Windows Defender Error 80070426, you need to uninstall Microsoft Security Essentials first. Once you’ve done that, you can follow our solutions below to get Windows Defender up and running.

Solution 1: Running an SFC Scan

It is likely that this error occurred during the upgrade process due to some problematic Windows system files in your computer. To determine if this is true, we recommend performing an SFC scan. Here are the steps:

dism. exe /online /cleanup-image /restorehealth

Note: If the error code appeared while you were upgrading, then instead of running the command above, you need to use your Windows installation media. After that, you must paste the text below on Command Prompt:

dism. exe /online /cleanup-image /restorehealth /source:[DRIVE]:\sources\sxs /limitaccess

Do not forget to replace [DRIVE] with the drive letter for your Windows installation media.

Solution 2: Checking if there are Software Conflicts

As we’ve mentioned, the Error Code 80070426 occurs due to software conflicts. So, to ensure that no other program will interfere with Windows Defender, you must perform a clean boot. Doing so will allow you to launch your operating system with only the essential programs, services, and drivers. This process will help you determine if there are other items coming in conflict with Windows Defender. Once you’re ready, just follow the instructions below:

After restarting your computer, check if the Error Code 0x80070426 is still there when you launch Windows Defender. If it isn’t, then you need to go back to the System Configuration window and enable a startup item. After that, restart your PC to see if the error is gone. Keep in mind that you need to perform this process for all the startup items until the Error Code 0x80070426 shows up again. Once you identify the culprit, you can disable it or remove it completely from your computer.
