Error 451 - What is it?

This is a typical SMTP error code. SMTP is the abbreviation for Simple Mail Transfer Protocol.

It is an internet standard for email transmission. In other words, SMTP is a text-based protocol in which the sender communicates with the mail receiver by issuing commands and receiving a response code.

The SMTP error 451 is displayed in the following format:

‘451 Requested action aborted: local error in processing’

This error message indicates that the program cannot send more messages and the server has hit the limit. This is because some mail servers have limits. The sever stops the task of sending and receiving emails when this limit is achieved.

The task image is corrupt/tampered 0x80041321
If you suddenly encountered an error that says, “The Task image is corrupt or has been tampered with”, along with an error code of 0x80041321, read on as this post will guide you on what you can do to resolve this problem in your Windows 10 computer. According to security experts, this kind of error has something to do with a corrupt scheduled backup task wherein each time the task service plans to execute a task, it validates a few things. And if it finds any issue with the integrity or corruption in the registry, it will mark those tasks as corrupt and throws the error 0x80041321. There are several options you can check out to fix the problem. You can try using the Registry Editor to edit and fix the corrupted tasks or you could also delete the schedule keys or the WindowsBackup file, as well as try deleting the task from the Task Scheduler or refresh the User_Feed_Synchronization. But before you of these potential fixes, make sure that you check every option and verify if it’s not associated or trying to run a file which it should not. In addition, make sure that you create a System Restore point as well so that you can undo any changes you will be making if anything goes wrong. Once you have these things covered, refer to each one of the options provided below.

Option 1 – Try to use the Registry Editor to edit and fix corrupted tasks

The first thing you can do to fix the problem is to edit those tasks via Registry Editor, as well as fix the corrupted ones in System32. Before you proceed, keep in mind that since you are dealing with the Backup triggered by the Task Scheduler, you can find the entries for the tasks in different locations. You can find the Task Scheduler at Task Scheduler Library > Microsoft > Windows > Windows Backup, whereas, you can find it in this path in the Registry Editor, HKEY_LOCAL_MACHINE SOFTWARE Microsoft Windows NT CurrentVersion Schedule WindowsBackup AutomaticBackup. On the other hand, you can find the Windows System folder at C:/Windows/System32/Tasks/MicrosoftWindows/WindowsBackup. You need to ensure that the name of the task name is the same as everywhere and take note of the name. Once you have these covered, follow the steps below.
  • Tap the Win + R keys to open Run and type “Regedit” in the field and hit Enter to open the Registry Editor.
  • Next, navigate to this key: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheTreeMicrosoftWindowsWindowsBackup
  • From there, take note of the GUID value in the ID entry of the task under the AutomaticBackup and Windows Backup Monitor folder.
  • After that, you have to remove the task registry entries related to the ID from these locations
    • HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCachePlain
    • HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheLogon
    • HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheBoot
  • Once done, you have to create a temporary copy of the corrupted task file by going to this location: C:/Windows/System32/Tasks/MicrosoftWindows/WindowsBackup
  • From there, look for the AutomaticBackup and Windows Backup Monitor tasks and copy them to a location where you can keep them safe.
  • Next, you have to fix the corrupted task by deleting it from this location: C:/Windows/System32/Tasks/MicrosoftWindows/WindowsBackup
  • After that, you have to recreate the task by going to Task Scheduler > Microsoft > Windows> Windows Backup.
  • Now click on the Action menu and on Import task and navigate to the backup files and import them.
  • Once you’ve created the tasks, run them manually and see if the error is now fixed.

Option 2 – Try to delete the Schedule keys in the Registry

  • Launch the Registry Editor and go to this key: HKLMSOFTWAREMicrosoftWindows NTCurrent VersionSchedule
  • From there, delete all of its sub-keys.
  • Once done, exit the Registry Editor and check if the Backup Tasks are now working.

Option 3 – Try to remove the WindowsBackup file

The next thing you can do to fix the problem is to remove the WindowsBackup file if the first two options didn’t work. It is possible that the problem has something to do with corrupted Task files. The task files are XML files that include parameters, programs to use, and many more. If any of these files end up getting corrupted, the task scheduler will have trouble running it and will throw the “The Task image is corrupt or has been tampered with” error.
  • To delete it, go to C:WindowsSystem32TasksMicrosoftWindowsWindowsBackup.
  • From this location, get rid of all the files. You could also these files via Command Prompt using the DEL command.
  • Once done, go to the Backup and Restore in the Control Panel and set up the Windows Backup again.

Option 4 – Try to delete the task from the Task Scheduler

If you don’t want to delete the files from Windows Explorer, you can delete them instead via Task Scheduler.
  • Open the Task Scheduler and go to Task Schedule LibraryMicrosoftWindowsWindowsBackup.
  • From there, delete both of the tasks and set up Windows Backup again.
  • Once done, go to the Task Manager and run the AutomaticBackup task again and see if it works.

Option 5 – Try to restart the Task Scheduler service

As mentioned, it is possible that the Task Scheduler service could be disabled. You could have disabled it when trying to enhance your computer’s performance and whatnot. Thus, you need to verify if it’s running or not and then restart it.
  • First, you need to tap the Win + R keys on your keyboard to open the Run dialog box.
  • Next, type “services.msc” in the field and click OK or tap Enter to open the Windows Services Manager.
  • You will see a list of Services and from there, look for the Task Scheduler service and double click on it.
  • After that, go to the General tab and click on the Startup Type options and then select “Automatically” from the given list.
  • Click on the “RUN” option and select the “Restart the Service” option.
  • And click on the “After Second Failure” option and then select the “Restart-Service” option again.
  • Now click on the “After Subsequent Failures” tab and select the “Restart the Service” option.
  • Finally, click on the Apply and OK buttons and then run the Task Scheduler and see if the issue is now fixed.

Option 6 – Try refreshing the User_Feed_Synchronization

According to security experts, enabling and disabling the User Feed sync also known as the User_Feed_Synchronization task can help resolve the problem.
  • Tap the Win + X keys and select the PowerShell (admin) option from the menu.
  • Next, type the “msfeedssync disable” command and tap Enter.
  • Repeat the same process but this time run the “msfeedssync enable” command.

Fix cannot load the Device Driver Code 38
Each you connect time external devices like scanners, printers, and the likes to a Windows 10 computer, the device either pushes the drivers through the USB or any other port, or you are expected to install the drivers through external media. In both cases, the driver will be loaded into the system, allowing you to use the device. However, it doesn’t always go smoothly as you could encounter some errors like the “Windows cannot load the Device Driver for this hardware because a previous instance of the Device Driver is still in memory ( Code 38 )”. If you encounter such an error in the Device Manager, then this means that a previous version of the device driver is still in memory and that each time the device is used, that previous version is loaded into memory and then unloaded which triggers the “Windows cannot load the Device Driver for this hardware because a previous instance of the Device Driver is still in memory (Code 38)” error. This kind of error occurs if the operating system loads the unwanted driver or if it fails to unload the driver. It could be that there is an obsolete version of the driver that’s still installed in the system or it could also be that you need to update your USB drivers as they could be outdated or the problem could also be due to some third party program that is interfering with the installation. Whatever the cause is, here are some suggestions you can check out to resolve the problem.

Option 1 – Uninstall previously installed drivers and reinstall their latest working version from the manufacturer’s website

The first thing you can do is to uninstall the drivers that are currently installed on your computer and then reinstall their latest working versions from their official sites. This kind of error is commonly encountered while loading drivers for scanners and printers. This is due to the fact that their drivers and software come along with a package which is usually in external media like CD or DVD. So when you install the software package, there’s a possibility that a newer version has been launched by its manufacturer. When that happens, you have to uninstall the previously installed driver package and then download the drivers from the manufacturer’s website and install them.

Option 2 – Run the Hardware and Devices Troubleshooter

  • The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
  • After opening Settings, look for the Update and Security option and select it.
  • From there, go to the Troubleshoot option located on the left-hand side of the list.
  • Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
  • After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 3 – Update or reinstall the Universal Serial Bus Controller driver

Since it could be a driver issue, you can try to update or reinstall the Universal Serial Bus Controller drivers using the Device Manager. Refer to the following steps:
  • First, click the Start button and type “device manager”.
  • Then click on the “Device Manager” from the search results to open it.
  • From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.
Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.
  • Restart your PC and then click the “Search automatically for updated driver software” option.
Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 4 – Restart your computer in a Clean Boot State

If the first three given options didn’t work and you still see the error when you connect external devices, you can try putting your computer in a Clean Boot State and then try connecting them again.
  • 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.)
  • Now try to connect the external devices and check if the error is now gone.

While an error during the Update process can be frustrating to encounter, there are a few simple solutions that can be employed to try to address the problem at hand. At least one of the methods for resolution does require some familiarity with the command prompt and other advanced tools, so if you are not completely confident in your ability to follow the steps mentioned below, you may want to get in touch with a qualified repair technician who can assist you in resolving the error code.

Solution

Restoro box imageError Causes

In some cases, the error in the Update process can be caused by a conflict between the operating system and the antivirus software running on your computer. In other cases, there may be a portion of the file missing or corrupted that needs to be fixed before the Update process can be run through to completion.

Further Information and Manual Repair

For users who are experiencing the appearance of Error Code 0x80244019 on their devices, there are a few methods that can be used to attempt to resolve the issue. While at least one of these methods is fairly simple to complete, even for basic users, the other does require some comfort in using the command prompt to input a series of commands. If you do not feel comfortable in following the steps listed below, contact a computer repair professional who is familiar with Windows 10 to assist you.

Here are the top methods for dealing with Error Code 0x80244019 on a Windows machine:

By running this tool, your system will attempt to scan the files involved in the Update process to try to determine where the conflict or error may be occurring. If one of the system files needs to be repaired or downloaded again, this tool can often resolve the issue on its own.

If the Troubleshooter tool successfully fixes the error, be sure to restart your computer before attempting to run the Update process again so that you can fully apply any changes that have been made.

In some cases, however, the Troubleshooter tool will not be able to find the problem or will be able to identify what the issue is, but not able to fix it. If this happens, it may be time to turn to Method Two.

Method Two:  Manually Perform a Reset on Windows Update Assets

To manually reset the assets associated with the Windows Update tool, follow these steps:

  • Step One: Open up the command prompt from the start menu and select the option to run it as an administrator.
  • Step Two: Run the following commands, hitting the enter key after each is put in:
    • Net stop wuauserv
    • Net stop cryptSvc
    • Net stop bits
    • Net stop msiserver
    • Ren C:\Windows\Software\Distribution Software\Distribution.old
    • Ren c:\Windows\System32\catroot2\Catroot2.old
    • Net start wuauserv
    • Net start cryptSvc
    • Net start bits
    • Net start msiserver
  • Step Three: Type in the word “exit” to quit out from the Command Prompt.

Once these steps are done, you can try to use the Windows Update tool again to see if the problem has successfully been resolved.

Step 1: First, open the Start Menu and look for the icon/tile of the required app in the menu. However, if you are not able to find the desired app, then just click on the All Apps option to navigate through all the apps that are installed on your PC. Step 2: Once you find the app, just right-click on it and select More and then click on the “Open file location” option. Step 3: This will open a new window with the shortcut icon. Right-click on the app’s shortcut icon and select Properties. Step 4: This will open the Properties window where you can add the shortcut combination. Keep in mind that just like the previous method, the custom shortcut has to be combined with the Ctrl + Alt keys. For instance, if you select E, then you also have to set a keyboard shortcut that includes Ctrl + Alt, so it will be, Ctrl + Alt + E. Step 5: Once you’re done, click on the Apply and OK buttons to save the changes made. You should now be able to use the custom shortcut key you’ve set.
