Error code 0xc000021a - What is it?

Error code 0xc000021a occurs when the system is unable to start or there’s a failure in critical system processes. Normally, it would take about several seconds for the system to boot and while on the startup process, error code 0xc000021a may take place to block the system to boot up. Users will get a blue screen of death (BOSD) when this error occurs. When upgrading to Windows 10, be careful; you might encounter other error messages such as error code 8007002c. 

Solution

Error Causes

There are several reasons why error code 0xc000021a occurs. It is important to have a full understanding of what caused the blue screen of death before attempting to fix the error by yourself. See below for a few common causes:

• Computer malware has infiltrated your device.

• Important files such as Winlogon.exe and Csrss.exe are damaged. Winlogon.exe file is responsible for handling the login and logout processes while Csrss.exe is a vital part of Microsoft Client or Server ‘Runtime Server Subsystem’. Once one of these files is damaged or deleted, a stop error will occur.

However, if you don’t feel like you will be able to perform the necessary steps on your own, be sure to get in touch with a qualified computer repair technician to help you in the resolution of this particular error.

Solution

Error Causes

Two things are generally behind the appearance of Error Code 0x80072efe on a Windows device. The first is that one or more of your registry keys are not available, have been corrupted, or are not installed properly. The second is that necessary DLL files aren’t working properly within your machine.

However, other things can mimic these causes, which is why the two methods listed below will resolve the issue in most cases.

Further Information and Manual Repair

Fortunately, there are two resolution methods that can be used quickly and easily when Error Code 0x80072efe arises on your Windows computer. Neither of these requires advanced knowledge or skill, but if you don’t feel comfortable with performing these steps on your own, it is recommended that you contact a qualified computer repair technician in order to get assistance.

Here are the best ways to resolve Error Code 0x80072efe on your computer:

Method One:  Check Your Time and Date Settings for Accuracy

If your time or date has been set incorrectly, it can make your system logs appear to have incorrect information, which can lead to the appearance of Error Code 0x80072efe. Because this is the easiest thing to fix if it is indeed the problem that is making the error code appear, this should always be the first thing that you try when this error code arises.

In order to check your time and date settings, follow these simple steps:

• Step One: Make sure that you are logged into your computer as an administrator.
• Step Two: Click on the time and date listed on the lower right edge of your screen. If the settings are not correct, choose the option to change the time and date.

If method one has not successfully resolved Error Code 0x80072efe, you may need to attempt method two.

Method Two:  Check Your Firewall Settings During Updates

In some cases, your firewall can prevent your machine from accessing the information that it needs in order for the installation or update to go through correctly. If that is the case, you can follow a few simple steps to turn off your firewall, just while you install the update, and then turn it back on.

In order to do so, follow these steps:

• Step One: In the Start menu, choose the option to open the Control Panel.
• Step Two: Select the option for System and Security, looking for and clicking on Windows Firewall.
• Step Three: Turn off any private network firewalls.
• Step Four: Reboot your computer to apply the changes that you have made.
• Step Five: Re-attempt to run your Windows Update.

Note that if this method allows you to successfully bypass the error code, you’ll need to make sure to turn the firewall back on when you are finished. Even though it can interfere with the Update process, your firewall is still very important to your computer.

Method Three: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

A general rule of thumb, which is followed by most users, is to download the specific missing DLL file and place it within the software’s installation directory. However, this can be harmful to your system as hackers often upload popular malicious DLL files to target systems. Thus, you should avoid downloading DLLs from the internet. And follow these steps to fix the DLL error:

• Restart your computer
• System restore to an earlier state
• Run a malware/virus scan
• Update all the hardware drivers
• Running SFC /scannow command in command prompt
• Then do as the error suggests, reinstall the program if it’s feasible. Game files can take several hours to install and therefore, reinstallation can be a cumbersome job. Also, frustrating if the error appears after reinstallation.
• Update device drivers manually, such as graphics drivers, DirectX software if you see DLL missing error while running game

Error Code 0x80072F8F manifests in one main way. It is known to appear as early as Windows 7, and mainly deals with an error that occurs in the update process, or when the computer is trying to connect to the online activation service. It can appear when the activation fails to verify the product key. The error code will present itself when the system realizes that the PC's date and time are incorrect. Error Code 0x80072F8F will also appear if the computer has determined that the time zone settings on the computer are not accurate.

When Windows is going through the installation process and is verifying all of the information associated with the computer, Error Code 0x80072F8F will arise, indicating that the information in the computer's settings is not valid. Correct times and dates are necessary when using serial validation keys to install Windows. When these settings are outside of the tolerated window, the problem will arise.

Error Causes

There is only one main symptom to look out for, and it will manifest during a Windows installation. In the midst of the installation, the computer will not be able to proceed with the installation if Error Code 0x80072F8F has popped up. Because the information cannot be verified, Windows will not be able to continue the installation process when the time settings are not accurate. This interrupts the process, causing the need to edit the settings, restart the computer, and try again. It is imperative to be sure that the date and time on the computer are inside of the tolerated window for the serial key.

• This error code will not give any information on how to correct it.
• Windows Error 0x80072F8F is displayed on the screen.
• The error code appears when typing the Windows serial key and proceeding.

Further Information and Manual Repair

When experiencing Error Code 0x80072F8F, the date and time need to be corrected in the computer settings menu, and then verify the correct time zone settings.  There are a few different ways to edit the time and date settings, and one may need to even edit the time zone settings. After this, restarting the computer may be needed. When booting into Windows, the validation code should be activated within 30 days of obtaining the serial number.

• Method One

Check the time and date settings.

1. Open the Start menu.
2. Select Settings, then Time and Language, then Date and Time.
3. Check and make sure that the PC is operating at the correct time and date.

Windows Vista had in it animated wallpapers on desktop but sadly how they were heavy on system resources Microsoft abandoned the idea. Moving forward a couple of years later we have Windows 10 but still, we do not have live animated wallpapers. Since I am the kind of person who does not want to wait on Microsoft and now it is time to bring animated wallpapers back I am going to make one all by myself and you are welcome to join the ride and do the same for you as well. Enough talk, let's dive into how we can make animated wallpaper for our Windows 10.

Choosing the application

First, we will need some form of application which can we look at our animated wallpapers and since they are animations it means video, so we will need a video player and what better choice than a VLC player, an open-source light weighs all-format player. Get a VLC player from here and install it.

Finding video source

The next thing is to of course have some looping video that we will use as background. There are many sites and ways to get seamless loop videos, I use this youtube channel for my backgrounds. Altho you can use any video footage you want it is recommended that it is not too long, that it is hi-resolution so we do not have pixels on-screen, and if you can, get it as seamless since we do not want to see stutter when the video is lopped from the beginning. So hopefully you have desired video and VLC player installed.

Putting it all together

Copy the following code and paste it into your search bar in Windows to open the Startup folder, or navigate to the Startup folder yourself via file explorer if you know where it is. %appdata%\Microsoft\Windows\Start Menu\Programs\Startup Now, next thing is to copy and past the VLC shortcut into this folder so it is started when Windows is first time booted. Right-click on the shortcut and in the edit field paste this: "C:\Program Files\VideoLAN\VLC\vlc.exe" --video-wallpaper --qt-start-minimized --no-qt-fs-controller --repeat --no-video-title-show --qt-notification=0 "C:\videopath\filename.mp4" where "C:\Program Files\VideoLAN\VLC\vlc.exe" is the path where VLC is installed, point this to where you have installed it "C:\videopath\filename.mp4" is the path where you have your video that you wish to use as animated wallpaper. Please note also that in my case there is mp4 as an extension but it does not need to be mp4, just use any extension VLC can open and play.

Conclusion

And that's it, you have successfully made an animated background or live wallpaper on your Windows 10 computer. You can change your wallpaper anytime by editing shortcut and giving it a new path to a new video or simply overwrite the existing one with a new baring same name.

It is no secret that Microsoft is trying to keep Windows relevant and that it is trying to make it as good as possible. A new Windows update will bring some interesting stuff in it which well some like it, some not so much. Among various technical and security updates Microsoft will bring some directly visible to each user.

First

of these features will be File explorer compact mode. This feature is a sort of spacing content in file explorer giving it easier access if you are using a touch screen device. Now, this feature is somewhat strange, and altho I can understand and get behind the logic of this move I am not sure I like it. Lucky for me and others who feel the same this option can be turned off for now.

Second

feature is something I can get behind, improvements for virtual desktops. There is an article on errortools about virtual desktops feature and I really hope you are using it since it is a great feature. Anyway, new update will bring us separate desktop wallpapers for each desktop and we will be able to arrange them in order we like.

Third

thing that I would like to address is animation features. We will have windows slowly fade and resize when opened, minimized, maximized, etc. So far we are unable to tell how this can and will it affect overall system performance. I am sure it will have some impact but hopes are that it will be kept to a minimum.
