Error codes in Windows often occur due to poor maintenance of one’s PC. To improve your system and reduce your machine’s risk of experiencing error codes, download a powerful automated tool. This tool is both powerful and user-friendly, making its benefits accessible to even the most non-technical Windows users.

One of the important functions in the Windows operating system is the Task Scheduler. It can automatically run various tasks at a certain time where you’ll have to add a task that needs to be executed and then choose the time it has to run at. So when that time comes, the Task Scheduler will run the task automatically. However, some users reported getting an Error 0x80070057 where the Task Scheduler fails to start. This kind of error may be due to a disabled service that prevents the service from running. It is also possible that the antivirus program interfered with the task – it could be that the Task Scheduler is somewhat in the block list since the antivirus adds it to the list automatically when it’s installed. On the other hand, it could be that you lack administrator-level privilege which is why the Task Scheduler was not able to carry out the task. To fix this issue, here are some suggestions you can try.

Option 1 – 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 2 – Try to temporarily disable the anti-virus program

As mentioned, the error could be due to the antivirus program or the Windows Defender Firewall installed in your computer. Thus, disabling them or any security software installed on your computer is always a good idea you can try when you’re not able to access the shared drive on your computer. There are times when you encounter problems like the Task Scheduler Error 0x80070057 due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program for the meantime and check if it fixes the error or not.

Option 3 – Run the Task Scheduler with an administrator account

Like pointed out, the Task Scheduler Error 0x80070057 may be due to the lack of admin privileges. Thus, you have to log in to an administrator account and try running the Task Scheduler again. It is also recommended that the administrator account you’re going to use as a password when logging in.

Option 4 – Repair the Task Scheduler by deleting corrupted tasks

Note that a single corrupted file can cause big problems so this option is quite important. And for you to delete a corrupted task or any task from the Task Scheduler, you have to use the Registry Editor if you are not able to use the Task Scheduler interface. To do so, follow these steps:

• Tap the Win + R keys to open the dialog box for Run.
• Next, type in Regedit and click on OK or tap Enter to open the Registry Editor.
• Then navigate to this path: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheTree

Note: In this path, you can see all the tasks that are currently set in the Task Scheduler. And since it would be hard to tell which one of them is corrupted, you have to delete the latest one in Task Scheduler last. But before you do so, make sure that you take note of the ID of the tasks. And for you to get the ID, you have to select the task you wish to delete and double click on the ID string located on your right-hand side, and then copy it in the Notepad.

• Right-click on the task name and then delete it.
• After that, delete the very same GUID which you have copied earlier from these folders:
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheBoot
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheLogon
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheMaintenance
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCachePlain
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheTasks

Note: You might not see the same GUID from these folders but if you see it, delete it right away.

• Next, navigate to this location: C:/Windows/System32/Tasks
• Delete the very same tasks you just deleted from the Registry Editor.
• Restart your PC and check if the Task Scheduler is back to its normal state or not.

Keeping your system updated is a must and Windows updates are definitely a great way to do that. These updates are essential since they provide important security and various fixes for bugs in your Windows 10 computer. However, there are plenty of instances when you encounter issues with Windows Updates and one of them is when the Windows Updates turn off automatically at random times. Some users reported that they saw a notification about Windows Updates being turned off. Note that the issue is not with the update itself since many users turned on the Windows Update and the system was properly updated. The issue is that the Windows Updates turned off all by itself. There could be several reasons why the Windows Updates turned off by themselves. It could be due to the antivirus program installed on your computer. Antivirus programs are known to cause issues with other programs, Windows updates components included. This can occur due to false positives as well as odd compatibility issues. Aside from antivirus programs, the Windows Update service itself could also be the root cause of the problem. There could be a corrupted file in the Windows Update folder or it could be that the Windows Update service wasn’t started properly. Any of these issues can be resolved by following the troubleshooting options given below. Make sure to follow each one of them carefully for better results.

Option 1 – Try to disable your antivirus program

Disabling the antivirus program or any security software installed in your computer is always a good idea you can try when the Windows Update process does not go smoothly. So before you try updating your computer again, make sure to disable the antivirus or security program and once the Windows Update is done, don’t forget to enable the antivirus program back again.

Option 2 – Try to make some changes in the Registry

• Tap the Wins key once and type in “command prompt” in the field.
• From the search results, right-click on Command Prompt and select the “Run as administrator” option to run it with admin privileges.
• Next, type the following command and tap Enter:

reg add "HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionWindowsUpdateAuto Update" /v AUOptions /t REG_DWORD /d 0 /f

• After that, type the following command and hit Enter again:

sc config wuauserv start= auto

 The command you entered will set the Windows Update to auto so you should be good to go.

Option 3 – Try to reset the Windows Update components

If by any chance that the second option didn’t work, resetting the Windows Update components could also help you resolve the problem. How? Refer to the following steps:

• Open Command Prompt with admin privileges.
• After that, type each one of the following commands and hit Enter after you key in one after the other.
  • net stop wuauserv
  • net stop cryptsvc
  • net stop bits
  • net stop msiserver

Note: The commands you entered will stop the Windows Update components such as Windows Update service, Cryptographic services, BITS, and MSI Installer.

• After disabling WU components, you need to rename both the SoftwareDistribution and Catroot2 folders. To do that, type each one of the following commands below, and don’t forget to hit Enter after you type one command after the other.
  • ren C:WindowsSoftwareDistribution SoftwareDistribution.old
  • ren C:WindowsSystem32catroot2 Catroot2.old
• Next, restart the services you’ve stopped by entering another series of commands. Don’t forget to hit Enter after you key in one command after the other.
  • net start wuauserv
  • net start cryptsvc
  • net start bits
  • net start msiserver

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.

If you encounter an error saying, “Invalid file handle” when you try to rename, copy, delete a file or other operations in your Windows 10 computer, then read on as this post will guide you in what you can do to fix it. This kind of error pops up when the operating system tries to carry out an operation on a folder or file using the following words:

CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9

When you rename or create a folder or file using the reserved words given above, you could encounter an error that says, “The specified device name is invalid”. This occurs since these words are Windows system reserved words that you can’t use, unlike any other words. Thus, if you have a folder or file which contains any of the reserved words on another computer that runs a non-Windows operating system and you try to copy or rename it Windows, then it’s no wonder why you’re getting this error message. In such cases, you can always click on the Skip button to stop the operation. However, if there are various folders or files, you can just use the Command Prompt to carry out the task. All it takes is a simple command that will get rid of the folder as well as the files in it. How? Refer to the instructions given below. Step 1: Tap the Win + R keys to open the Run utility. Step 2: Next, type “cmd” in the field and then tap Enter to open Command Prompt. Step 3: After opening Command Prompt, execute the following command:

rd \.file-folder-path /S /Q

Note: The “rd” command will remove the directory or the folder while the “\.” command will select the current computer. The “/S” command, on the other hand, helps you in removing all the sub-directories and the files that are in the CON folder. The “/Q” command is not really mandatory since it helps you remove everything silently without any confirmation message. For example, if you have a folder named “CON” located on your Desktop, the path will be like this “C:/Users/<username>/Desktop/CON”. In this case, the command should be like this:

rd \.C:Users<username>DesktopCON /S /Q

However, if the error pops up for a whole different reason, you could use the following command instead to remove the reparse point extended functionality. Once you’ve entered the given command below, you should now be able to delete the file.

FSUTIL reparsepoint delete C:Users<username>DesktopFileName DEL C:Users<username>DesktopFileName

If VirtualBox suddenly displays a black screen without any text or mouse cursor when you are trying to boot a guest operating system, then read on as this post will guide you in fixing such an issue. This black screen occurs when Windows 10 failed to provide a specific setting that VirtualBox requires. Consequently, you will not be able to install or use any guest operating system in VirtualBox even if your PC has virtualization support, the best thing you can do now is to fix this black screen issue. There are two ways you can fix this black screen in VirtualBox, you can either try to disable Hyber-V or disable 3D Acceleration. For more details, refer to each one of the given options below.

Option 1 – Try to disable Hyper-V

Hyper-V is a built-in virtualization tool available in Windows that helps users in creating a virtual machine as well as install a guest operating system without using any third-party tool like VMware, VirtualBox, and many more. However, the problem with this virtualization tool is that some systems cannot run it and VirtualBox simultaneously which is most likely why the screen abruptly turns into black. Thus, you have to disable Hyper-V to resolve the problem. How? Refer to these steps:

• In the Start Search, type “Turn Windows features on or off” and then click on it from the results.
• Once you’ve opened the Windows Features window, remove the checkmark from the Hyper-V box.
• Click the OK button and then restart your computer.
• Now try to use VirtualBox again and see if the problem is fixed.

Option 2 – Try to disable 3D Acceleration

The guest operating system will use the host computer’s GPU to render 3D graphics if you enable the 3D Acceleration for the virtual machine. To simply put it, it will enhance the graphics of the virtual machine and will let you use 3D graphics. Although it may seem nice, it can actually cause the black screen to appear as well so you might have to disable it to isolate the problem. In fact, a lot of operating systems have failed to use the 3D Acceleration for the guest operating system because of this black screen issue. To disable it, follow these steps:

• Open VirtualBox on your computer and select the virtual machine.
• Next, click on the Settings button and go to the Display section.
• After that, look for a checkbox named “Enable 3D Acceleration” located on your right-hand side and then uncheck it.
• Save the changes you’ve made and reboot your PC and see if you can now run the virtual machine without any problem.
