Fix 0X800F080C Error in Windows 10

Error 0X800F080C is tied to corrupted system files and .NET framework issues. In this article, we will focus on how to fix it starting first with .NET fixes and then moving to system-related ones. Follow the guide step by step so you can fix this error fast and easily.

.NET issues

As previously stated 0X800F080C error can occur due to issues with .NET framework, 3.5 framework to be more precise and there are two ways we can fix this error. Follow the guide below as presented:

  1. Install .NET 3.5 framework from Windows features

    First thing is to try and install the framework from Window features itself. Sometimes installation and activation of .NET 3.5 in other ways can result in this error. To install it do the following:
    Press ⊞ WINDOWS + R to open the run dialog
    Inside run type in appwiz.cpl and press ENTER to open up the Programs and Features menu
    Inside the Programs and Features menu click on Turn Windows features on or off.
    Check the box associated with .NET Framework 3.5 (this package includes .NET 2.0 and 3.0)
    Press OK
    Click on YES and wait for the package to be installed then reboot your PC

  2. Run the .NET Repair Tool

    If the previous step was not successful or you already had .NET 3.5 installed then run the troubleshooter in order to fix issues.
    Go to the official Microsoft .NET framework repair tool website here and download it.
    Once downloaded install the tool and follow onscreen instructions.

Corrupted system files

If the previous solution has not provided you with results then you have system file corruption that needs to be fixed. Move from one solution to another as presented below:

  1. Run SFC scan

    SFC scan is a built-in Windows tool for solving corrupted system files issues, it is fully automated and does not require from the user any kind of knowledge or information. To run it and scan the system do the following:
    Press ⊞ WINDOWS + X to open the secret menu
    Left-click on the command prompt (admin)
    In command prompt type SFC /SCANNOW and press ENTER
    Wait for the process to finish, do not interrupt it and once it is done, restart your computer

  2. Run DISM scan

    DISM scan is similar to SFC scan but it tackles different types of system file corruption and it is recommended to run it also after SFC has been completed. Please note that for DISM scan to be successful you will need a stable internet connection since DISM will replace corrupted files with new ones downloaded from Microsoft. To run it do the following:
    Press ⊞ WINDOWS + X to open the secret menu
    Left-click on the command prompt (admin)
    inside command prompt type: exe /online /cleanup-image /scanhealth followed by ENTER, then type: Dism.exe /online /cleanup-image /restorehealth also followed with ENTER.

Fix VIDEO_SCHEDULER_INTERNAL_ERROR
As you know, the Graphics Card in a computer is one of the important components in an operating system as they are responsible for rendering various objects in your computer. However, there are cases when the performance of this rendering can degrade and your computer can trigger a VIDEO_SCHEDULER_INTERNAL_ERROR Blue Screen of Death error instead. The VIDEO_SCHEDULER_INTERNAL_ERROR bug check has a value of 0x00000119 which means that the video scheduler has detected a fatal violation in your computer. Before you troubleshoot the problem, you might want to perform System Restore first as it might help you fix the Stop error. To perform System Restore, refer to these steps:
  • First, press the Win + R keys to open the Run dialog box.
  • After that, type in “sysdm.cpl” in the field and tap Enter.
  • Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.

Option 1 – Try to manually check the Graphics Card hardware

You might also want to check the physical status of your Graphics card and you can do this by disconnecting the Graphics card or any other external device connected to your computer. Once you’ve removed the external device, check it for any damages. If there’s none, connect it back to your computer and check if the VIDEO_SCHEDULER_INTERNAL_ERROR Blue Screen error is fixed or not.

Option 2 – Try removing hardware or drivers that you’ve installed recently

If you have recently installed some hardware or drivers, you might want to disable or remove them since external devices are proven to be one of the factors that trigger Blue Screen errors like VIDEO_SCHEDULER_INTERNAL_ERROR. All you have to do is physically disconnect any external devices that are connected to your computer and then check if it fixes the BSOD error or not.

Option 3 – Try to rollback, update, or disable the Graphics card drivers

  • 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 4 – Uninstall any faulty drivers

You can also uninstall any faulty drivers via Device Manager. How? Refer to these steps:
  • Tap the Win + R keys to launch the Run dialog box.
  • Then type “devmgmt.msc” in the field and tap Enter to open the Device Manager.

  • Once you’ve uninstalled them, restart your computer to allow your computer to reinstall the faulty drivers you’ve just removed.

Option 5 – Run System File Checker at boot time

  • Once you get to the Welcome Screen part, click on Next.
  • Afterward, click on the Repair your computer option located on the bottom-left part of the window.
  • Then click on Troubleshoot.
  • Next, select the Advanced Options and then Command Prompt.

How to Fix Task Scheduler Error 0x80070057
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.

Windows 365, what it is, and how you can get it
Windows 365Microsoft has announced Windows 365, a new cloud-based operating system aimed mainly at businesses of all sizes. Just after Windows 11 announcement and presentation, we are seeing another Windows announcement from Microsoft. Dive into the following text in order to find out what exactly is new Windows 365, its role in today's IT world, and do you need it?

What is Windows 365 and when it is coming out?

Windows 365 is planned to be released this year (2021) on August 2nd. It is the first Microsoft cloud-based operating system meaning that OS itself will be installed on the cloud server and it will be accessed by the user via a web browser. Essentially you are accessing a remote PC with Windows on it, you can install whatever Windows application you want and use it as it was on your computer. When you disconnect from the cloud computing and reconnect again from the same or another device you will continue exactly where you left off. Cloud PC will remember the state it was left off and will greet you in that same state once it is awakened again. This of course offers some great benefits like moving from laptop to desktop and continuing exactly where you left off.

How can I access Windows 365?

Any device which has a web browser will be able to access Windows 365 making it a really great solution for business on the move or for anyone who switches devices during the day. That being said it is clear to see that Windows 365 can be accessed via Linux, macOS, iOS, Android, or any other operating system on any computer, tablet or phone.

Who is this OS made for?

Microsoft’s general idea is that Windows 365 is primarily made for business which in their minds can benefit most out of it. So far it is not made for a single user although there is a possibility that even a one-man business can subscribe and create accounts for it.

Price and technical characteristic

Microsoft will bill Windows 365 on a per-user, per-month basis. In other words, businesses will pay a fixed amount per employee every month. There will be two tiers: Windows 365 Business and Windows 365 Enterprise. Microsoft also said it will offer different performance tiers. Businesses can choose to pay for more CPU, RAM, and storage resources for certain cloud PCs depending on their needs. Microsoft told me the smallest configuration would be one CPU, 2GB of RAM, and 64GB of storage. The largest will be eight CPUs, 32GB of RAM, and 512GB of storage. After a business has chosen its plan tier and performance options, that business will pay a fixed amount every month. This is unlike Azure Virtual Desktop, which Windows 365 is built on. With Azure Virtual Desktop, companies pay on a usage model, depending on how much the remote system is used every month.

Conclusion

Windows 365 is around the corner and if you are a business no matter small or large with the need for software on the go, Windows 365 might be a worthwhile investment and a great asset to your business.

Windows 11 slows down some SSD drives
In the latest Windows 11 fiasco, it is reported that the operating system is slowing down some SSD drives. Good thing is that it does not affect all of SSD on the market but the ones which it is affecting can see even a 45% of speed drop. ssd driveMicrosoft has not published a solution to this issue, but users point out two potential problems. The first is a security mechanism based on disk virtualization, which is supposed to slow down the performance of SSDs. The second, in turn, is related to the place of installation of Windows 11 – users indicate that if the performance test is performed on a medium with no files associated with the system, its performance results are similar to the parameters given by the manufacturer. Transfer speeds were to be slightly improved with the latest Windows 11 update 22000.348. However, users are still waiting for a solution to the problem that significantly reduces the efficiency of SSD media.

How to Fix the Error 550

Error 550 - What is it?

Error 550 is an SMTP (Simple Mail Transfer Protocol) outgoing server error code. It usually occurs when you try to send emails through your Outlook account and the email message encounters a relay error. The email returns back without being delivered with a 550 error message. The error message is prompted as either of the following:
"550 Requested action not taken: mailbox unavailable" "550 5 2 1 mail from refused spam site"
In other words, the error code 550 means that your SMTP server was not able to deliver the sent email to the user.

Further Information and Manual Repair Regardless of what the reason may be for the error 550 code occurrence, it is advisable to repair and fix the issue quickly to avoid inconvenience. You may not be able to send emails from your Outlook account if the error continues. This can cause great hassle in corresponding with others timely and may create a big communication gap. Here are some quick and efficient ways to resolve this issue on your system:

Solution 1:

There is no need to panic when you encounter error 550. Sometimes the error message may occur because you inserted the wrong/ incorrect email address of the recipient. In such a case, cross-check the recipient’s email address to verify if it is correct. If not, insert the correct address and try sending the email again.

Solution 2:

If the error still persists, try other methods to resolve it. Sometimes error 550 can also occur due to incorrect SMTP settings. Fix it to resolve the error. This can be done by opening your Outlook settings Tools and Accounts option. Now go to view/change the email account for the email account you are having problems with. After that check, the SMTP server is set to mail.yourdomain.com. Then click more settings and then click the outgoing server tab. See if the ‘My server requires authentication for the outgoing server’ is checked. If not, then check on it. Then simply save to confirm changes. Now try emailing again. Hopefully, this will resolve the issue.

Solution 3:

Another reason for the error occurrence can be ISP blockage. When the junk email volumes increase, network administrators (the people who are responsible for managing ISP servers) place restrictions on SMTP email servers to prevent spam on their network. If this is the reason, contact your ISP administrator to resolve the issue.
