How to Fix Windows 10 Error 0x80004002

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.

This will stop the program, but the program will start back up automatically when the computer restarts. While this program is stopped, uninstall Essentials.

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.

You can also reset the Windows Update-related folders or the Microsoft Store or fix the Windows Update files by using the DISM tool. On the other hand, you can also use the Registry Editor or check Windows Services. For more details regarding these potential fixes, refer to each one of the given options below.

Option 1 – Try to re-register the Background Intelligent Transfer Service DLL file

You may have to re-register the Background Intelligent Transfer Service DLL file using the regsvr32.exe before you can successfully install the program and fix ntdll.dll file crash error.

For everyday home use, Windows 11 S mode is the most secure feature to have on your PC. This is a safety protocol where only apps from Microsoft Store are allowed to be installed. This eliminates the risk of installing third-party apps that may contain viruses or malware. Furthermore, S-mode protects your web browsing activity through the Microsoft Edge browser. S-mode does not allow you to use other browsers for security reasons. If you are using Windows 11 in S-mode, your PC and data will be secure in most parts. You need not buy antivirus when using Windows 11 in S-mode.

Windows Defender

The inbuilt security suite, Windows Defender was launched for the first time in 2006. Earlier to that it had existed and was known as Microsoft AntiSpyWare. Windows Defender has undergone significant improvements over the years. In its latest version available with Windows 11, Windows Defender offers a comprehensive range of security features. It is available under the Windows Security system. Some key security features include real-time virus and threat protection, account protection, firewall & network protection, app and browser control, parental controls, and device (hardware) security. This is comparable to security features offered by third-party antivirus programs.

Microsoft Account

In Windows 11, it is necessary to use a Microsoft account that will be linked to your device. This ensures the security of your data in case your device is lost or stolen. You just need to make sure that you have set a strong password for your device. Windows 11 also has Bitlocker that keeps your data in encrypted form.

Ransomware protection

In view of rising cases of ransomware, Microsoft has introduced dedicated ransomware protection in Windows 11. It works by stopping apps from carrying out unauthorized changes to files and folders. Users can choose their important files and folders that they want to be protected from ransomware.

Conclusion

As we went through Windows 11 security features, we can clearly see that it is packed heavily with many security features that aim to protect your data and your identity. Looking at them, one can clearly come to the conclusion that you do not really need any third-party software and that Windows itself can catch and protect most of the issues, and they would be right. If you use Windows 11 carefully, meaning that you go only to trusted websites, do not open suspicious emails, and click on suspicious links, if you do not use extensively external USB devices or mass media you really do not need any kind of third party protection, Windows built-in tools will do well and keep you protected. However, if you do come in contact with other people's USB devices if you surf over the net, and overall if you really want to be at peace of mind that you are protected you will still need a well-established third-party software protection solution. Windows 11 has great security features, best so far in any Windows but it is still far from being a solution that does not require dedicated protection solution. So do yourself a favor and grab one.

The Adaptive Brightness setting in Windows 10 is a useful setting you can use in adjusting your computer’s brightness. It helps you get the brightness automatically based on the light around your computer. However, there are times when it does not work or it doesn’t turn off when you want it to. If this issue happened right after you update or install Windows 10, then read on as this post will give you a couple of options you can try to resolve the problem.

Option 1 – Try to run the Power Troubleshooter

The first thing you can do to resolve the issue with Adaptive Brightness is to run the Power Troubleshooter as the problem could occur due to some conflicted power settings. To use it, refer to the following steps:

• Open the Windows 10 Settings panel and go to Update & Security and then to Troubleshoot.
• After that, scroll down to your left-hand side and click the Power option.
• From there, you should see the “Run the troubleshooter” button. Click on it to fix the problem.
• Afterward, follow the next on-screen instructions that follow.

Option 2 – Try disabling or turning off the corresponding options in GPU settings

The problem might be due to the Graphics card settings. If you are using either an AMD graphics card or the HD graphics of Intel, you may have to disable the power-related options in the GPU settings. To be specific, you have to disable the Vari-Bright in AMD graphics card settings or the Display Power Saving Technology under Intel’s Graphics panel.

• AMD users:
  • Open the AMD Radeon settings panel.
  • Then go to Preferences. From there, select Radeon Additional Settings.
  • Next, go to the Power tab and click the PowerPlay option.
  • You should find an option called “Enable Vari-Bright” located on your right-hand side. Remove the mark from its checkbox and then save the changes you’ve made.
• Intel users:
  • Open the Intel Graphics and Media Control Panel from your Desktop.
  • Then select the Basic mode and go to the Power tab.
  • From there, select “On battery” as Power Source and then you’ll get the Display Power Saving Technology option. It should be set to enabled by default.
  • Now remove the mark from the checkbox and then save the changes you’ve made.

Option 3 – Try resetting the Power Plan defaults

You might also want to use a command-line tool to resolve the problem. This command-line tool is known as PowerCfg. It is a command utility tool that will scan your computer for 60 seconds to know its power. This tool gives detailed results in the form of an HTML report that will help you in evaluating the real cause of the battery drain issues. You can also use this tool to reset the Power Plan defaults of your computer. To use it, follow the steps below.

• Open the Command Prompt as administrator.
• Then type in the following command and tap Enter to execute it:

powercfg –restoredefaultschemes

• After the command has been executed, restart your computer.

Option 4 – Try updating your Graphics drivers

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in devmgmt.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.

Note: You also have the option to 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.

Option 5 – Try disabling adaptive brightness via Registry Editor

Since you will be dealing with Registry files in this post, you need to create a System Restore point first. Once you have that covered, proceed to the following steps:

• Tap the Win + R keys to open the Run dialog box.
• Next, type “regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to this path: HKEY_LOCAL_MACHINESOFTWAREIntelDisplayigfxcuiprofilesMediaBrighten Movie
• Now double click on the “ProcAmpBrightness” and set its value to “0”.
• Now go to this path: HKEY_LOCAL_MACHINESOFTWAREIntelDisplayigfxcuiprofilesMediaDarken Movie
• From there, double click on “ProcAmpBrightness” and set the value to “0”.
• Then close the Registry Editor and restart your PC and then see if the problem’s fixed or not.

What is Backup Error 0x80070002?

Error 0x80070002 shows once you’re done backing up files through the Windows Backup program on a system running Windows 7, you see a notification that pops up with a message that reads something like: “Check your backup results. The backup completed but some files were skipped.” You try finding out the reason and you hover over to the Options button beside the message, then you get to read the following lines: “Check your backup results. The backup completed but some files were skipped. View skipped files.” Upon clicking the “View Skipped Files” option, the backup error 0x80070002 pops up on your screen and you’re left scratching your head, wondering what you’re going to do now.

Solution

Error Causes

There are multiple error logs that you will encounter in backup error 0x80070002 as per different conditions. The two most common cases in which this error shows up are stated below:

Case 1

You will see the following message when you press “View skipped files”: “Backup encountered a problem while backing up file C: Windows/System32/config/systemprofile. Error: (The system cannot find the file specified. (0x80070002))” You will face this case if you have backed up a library that included custom folders that were located in your user profile.

Case 2

Upon pressing “View Skipped files” you will encounter the below-mentioned messages: “Backup encountered a problem while backing up file C:/Users<User>AppDataLocalLow. Error: (The system cannot find the file specified. (0x80070002))” “Backup encountered a problem while backing up file C:/Users<User>Contacts. Error: (The system cannot find the file specified. (0x80070002))” “Backup encountered a problem while backing up file C:/Users<User>Searches. Error:(The system cannot find the file specified. (0x80070002))” You are likely to encounter any of these messages in case:

• The Windows Backup program is trying to back up your files in either one or all of these folders (LocalLow, Searches, Contacts).
• All three of these folders don’t exist in your system.

Keep in mind that all three of these folders exist due to the installation of certain programs and applications on your system.

Notes

The backup error 0x80070002 is also found to occur while using USB devices instead of storage devices. Other occurrences include the times when input/output (I/O) operations are performed on the USB device, which results in failure.

Further Information and Manual Repair

To make sure this issue is resolved, you will have to follow either one of the following solutions as appropriate to your situation:

Solution for Case 1

1. Ignore the error. The store files of the custom library in your user profile will not be created as backups.
2. Transfer the library folder from where it currently exists to a place outside its current folder (user profile). For instance, you can move the library folder to an entirely new destination such as “C: My Folders”
3. Remove the library folder from the list of files that you are backing up using the Windows Backup program. Then, add the original place of the library’s content in the list.
4. Go back and check step two. If carried out successfully then add a link to the folder you moved from the library. Check to see if the backup includes the library folder. To make sure, you have to do as follows:

• Go to Start and select your username.
• Hover across to the folder you wish to move, right-click on it and select “Cut”.
• Head to the navigation pane and search for the area you will store the folder in, right-click and select “Paste” so that the folder is moved to that location.
• Right-click on the folder that you just moved and select “Copy”.
• Go back to Start, select your username, right-click any vacant space in your folder and select “Paste Shortcut”.

Note: If you want to store the folder in a different place other than the folder in which it currently exists (user profile), you will need to create a new folder. In order to do so, go to the Windows Explorer menu and look up the root of the drive. Hit “New Folder” and then choose edit to change its name. You can set it as any name for instance, “My Folders”.

Solution for Case 2

You can ignore this error safely. However, if you wish not to see this error in the future during your backup operations then you will need to carry out the following steps:

1. Create all the folders listed in the error message including LocalLow, Contacts, and Searches.
2. Remove all of these folders from the Backup settings to make sure they aren’t being backed up then add the folders which are in their original place. To carry out this procedure, you will have to follow the below-mentioned steps:

• Head over to the Control Panel and open “Backup & Restore”.
• Go to the Backup section and select “Change Settings”.
• Click Next in the Setup backup dialog box.
• Select “Let me choose” in the dialog box termed “What do you want to back up” then proceed by clicking Next.
• Expand Data Files, expand <user> Libraries, expand Additional Locations then proceed by clearing out the AppData Folder, searches, and Contacts checkboxes.
• Expand Computer as well as the item for your system drive (expand Local Disk (D:)), expand users, expand <user>, then go to AppData, Searches and Contacts and mark them if they are present.
• Proceed by clicking next and select “Save Settings” then exit.
• Back to Backup & Restore, select Back up now and your new backup will begin proceeding. The entire process will be complete without any errors now.
