Error Code0x80070426 - What is it?

When Windows evolved into Windows 10, the program known as Windows Security Essentials is no longer. It is now the program known as Windows Defender. When a computer is upgraded from a previous version of Windows up to Windows 10, the Windows Defender takes over and will replace the Security Essentials. In a small percentage of Windows 10 upgrades, something will go wrong and the new program will fail to replace Security Essentials. The result will be that the operating system has both of the programs installed. In this case, Windows Defender will not offer any protection and Security Essentials will not be able to defend either. This error code will also present itself when the Windows Mail App in Windows 10 fail to retrieve and sync email from the user's account.

Common symptoms include:

• There will be an error message that says: “An error has occurred in the program initialization. If this problem does continue, contact your System Admin. Error code 0x80070426.”
• The computer will be left completely vulnerable to spyware and viruses.
• The Windows Mail App will not be able to retrieve mail and will not sync with the PC user's mail.
• The user can be doing anything on their computer and the error code will show up unprompted.
• The computer will lock up, become slow, crash, or even freeze when dealing with error code 0x80070426.
• The programs from an older version of Windows do not replace the newer version from Windows 10.

Solution

Error Causes

Error code 0x80070426 will present itself when a PC user has upgraded their OS from a previous version of Windows to the new Windows 10 version. When this happens, a small portion of users will experience the disconnect between older versions of specific programs, namely the virus protection. When the previous version of the program under a different name is not completely removed and the new virus protection program is installed, the programs will cancel each other out and collectively offer no protection.

This error code may also be found when Windows 10 tries to sync the user's email with the Windows Mail App.

Further Information and Manual Repair

There are a few methods to repair this problem. It should be noted that should anyone feel that the instructions are too complicated, they should contact a Windows repair technician to ensure that the error is fixed properly.

Method One: Uninstall Microsoft Essentials

Hold down the Windows Key and press R. Type in taskmgr into the run dialogue. You should locate the Windows Defender Service (this may show up as Windefend). Right-click on it and then choose Stop.

To do this: go to Control Panel, Programs, and Features, Uninstall a Program. Alternately, you may hold down the Windows Key and press R, type in appwiz.cpl, click OK, and then locate Microsoft Essentials. Uninstall it, and then restart your computer.

After this is done, go to Settings, Update, and Security. Choose Windows Defender and ensure that Real-time protection is on. Refer back to the Task Manager, Services. Make sure that Defender service is on and running.

Method Two: If the problem occurs in the Windows Mail App

When error code 0x80070426 presents itself in the form of an error with the Mail app, it may be necessary to run an SFC scan.

Right-click on the Start menu or Windows icon, and select Command prompt. The command prompt may be navigated by using shortcut keys Win and X and then select it.

Run the command prompt and then type in sfc /scannow and then press enter. The SFC scan will be run, and be careful not to abort the process before it has finished. This will scan for any files that are lost or corrupt on the PC.

If the scan has found any corrupt files, type in this code and then hit Enter: findstr /c:”[SR]” %windir%LogsCBSCBS.log >”%userprofile%Desktopsfcdetails.txt.

To skip the repair of corrupt or missing files, type in: Dism /Online /Cleanup-Image /RestoreHealth. The details of the scan can be found on the sfcdetails.txt file that will be on the desktop.
