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.

The Photos app in Windows 10 is the default photo viewer. However, there are times when it might encounter some problems while you use it. One of these problems in the Photos app reported recently is where users try to export or share the images and videos from the app but weren’t successful in doing so. This can be really quite a hassle in opening images on your computer, especially since the Photos app is the default photo viewer in Windows 10 and if you don’t have any other photo viewer app installed. This kind of problem in the Photos app can be noticed when you try to use the “Remix” function for both photos and videos. In other words, this problem can occur with just pictures, videos, as well as a combination of both. So if you are trying to watch a video using this app, then you wouldn’t be able to play it. In such a case, the only thing you can hear is the audio but you wouldn’t see anything except for a hazy purple screen that has not export or share option. There are several possible causes for this problem and it could be fixed by updating the display driver/graphics driver or disabling the hardware-accelerated video encoding. You could also try updating or resetting or reinstalling the Photos app. For more details, follow each one of the suggestions provided below.

Option 1 – Try to update the Graphics driver

You can try to update your Graphics card driver using the Device Manager in your computer to resolve the blank dialog boxes problem or you can also go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it. To update your Graphics driver via Device Manager, refer to these steps:

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Option 2 – Try disabling the hardware-accelerated video encoding

The next thing you can do to fix the problem is to disable the hardware-accelerated video encoding in your computer. To do that, follow these steps:

• Open the Photos app and click on the visible three dots located in the upper right corner of the app and then select Settings.
• From there, you should see the version number of the app in the “About this app” section. So if your app is version 2018.18071.****0.0 or greater, you should see the Video section which has a toggle button.
• Turn that toggle button off to disable hardware-accelerated video encoding in the Photos app. This should fix the problem, if not, simply follow the next given options below.

Option 3 – Try to update the Microsoft Photos app

• Open the Microsoft Store and click on the three horizontal dots for the menu located on the top right portion of the window to see the options.
• Next, select Downloads and updates and then click the Get updates button in the top right. This will install any pending updates for all the apps including the Microsoft Photos app using the Microsoft Store.

Option 4 – Try resetting the Photos app

• To get started in resetting the Photos app, open the Windows 10 Settings.
• Then go to Apps > Apps & features.
• After that, scroll down until you see the Photos app option – click on it and open its Advanced options.
• From there, you will see the Reset button, click on it and click and then click on it once more to confirm.

Note: The process may take a couple of minutes to complete. Once it’s done, open the pictures again using the Photos app.

Option 5 – Try reinstalling the Photos app

If none of the options given above worked, then you might want to consider reinstalling the Photos app. Unlike what most users think, it isn’t really that hard reinstalling preinstalled apps as you have the Windows PowerShell for that. To use this program in reinstalling the Photos app, follow these steps:

• Open the Windows PowerShell program with admin privileges and key in the following command:

Set-ExecutionPolicy Unrestricted

• After that, execute this second command to re-register and reinstall the Microsoft Photos app.

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}

Note: In the command given, do not forget to replace the “PackageFullName” with the actual package name for the Photos app. After executing the command, it will uninstall the Photos app from your computer so you need to install it again from the Windows Store by simply looking for it. Once you found it, just click on install to start the installation process.

If you suddenly encounter Error 0x80000003 while trying to execute a random file then read on as this post will show you how you can fix such an error. Obviously, it mostly happens on executable files or .exe files and is most likely caused by the conflict in the execution of some registry files or it could also be caused by missing drivers or it could also be due to some incompatible hardware which is why you’re unable to run the executable file. When you encounter this error, you will see the following error message on your screen:

“The exception Breakpoint, A breakpoint has been reached, (0x80000003) occurred in the application.”

As you can tell, the Windows Executive STATUS message is a warning and if you are given an option, you must select one of the options from the message box. So if you are running the application in an end-user environment rather than in a development environment, you must contact the supplier of the running application regarding this error message since this shouldn’t be happening when a finished program is running. Before you get started executing the troubleshooting guide given below, make sure that you create a System Restore Point first since you will be dealing with some critical settings in Windows. Having done this, proceed to the options provided below.

Option 1 – Try to run the CHKDSK utility

Running the CHKDSK utility might also help you resolve Error 0x80000003. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

Option 2 – Try to run a System File Checker scan

You can also try to run a System File Checker or SFC scan in order to scan your computer for corrupted files that might be the cause behind the Error 0x80000003. Once it finds any corrupted system files, it will automatically fix them. To run System File Checker, here’s what you have to do:

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Restart your computer after the scan is completed.

Option 3 – Perform a Clean Boot

There are some instances that some conflicting programs installed in your computer might be the one that’s causing the Error 0x80000003 to appear. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Option 4 – Run the Memory Diagnostic Tool to check for Memory leaks

• Tap the Win + R keys to open Run and type mdsched.exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:

  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Option 5 – Try contacting the developer

If you find that you’re getting Error 0x80000003 on only one particular application, then you can try to contact the developer of the software that’s throwing up this error. All you have to do is search the web for the official support channel of the software and discuss the error from there.

TCI/IP or as known as Internet protocol is one that controls packets that are sent over the internet and makes sure that each one has reached its destination so you can pleasantly browse your favorite websites. The setting for the given protocol is stored locally on your machine and most of the time, everything works fine and good, but sometimes, these settings can get corrupted.

Malware or other software can temper with setting making TCP/IP making it wrong and throwing nondescript connection errors in your face. If you are faced with this issue worry not because fixing this issue is really easy.

Before we actually go and fix the issue please do scan your system with your protection suite just to be sure that if there is any kind of malware on the system it is properly removed from it.

Resetting TCP/IP

First thing is to open search and find PowerShell, press the Windows key on the keyboard, and type in PowerShell so search results are shown. Click on Run as administrator to open PowerShell in elevated mode.

Once PowerShell is opened type indie it:

netsh IP reset and press ENTER. The task will start executing and at this point you will see a lot of Resetting, OK! messages. Once everything is finished restart your PC and you are good to go.
