3 Methods To Fix Qtcore4.dll Error

If you suddenly see a black border in your computer’s display then you might be wondering how come this happened but worry not for this post will give you a couple of suggestions that could help you resolve the problem. The black bar could appear at the bottom or just the sides of the screen. Whichever it may be, there are options you can check out. Refer to the options givens below and make sure to follow them carefully.

Option 1 – Try checking the screen resolution

You might want to try checking the resolution of your screen.

• Open the Windows 10 Settings and go to Display.
• Next, go for the “100% (Recommended)” option under Scale and layout for the size of the text, apps, and other items.
• After that, select the Recommended setting again under Resolution.

Now check to see if the black bars are still there. They should be gone at this point, but if for some strange reason nothing has changed, then attempt the steps below.

Option 2 – Try updating Graphics & Monitor drivers

You might want to try updating your graphics and monitor drivers if you haven’t updated them for some time now. To do that, refer to these steps:

• 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 Graphics drivers or the Monitor drivers and then click each one of them.
• After that, right-click on each entry 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 can also try to roll back the graphics and monitor drivers back to their previous versions if updating them didn’t work. You can also try visiting the manufacturer’s website and download the graphics or monitor driver setup for your operating system.

Option 3 – Try to run the DISM tool

You can also run the DISM Tool as it might also help in getting rid of the black border or bar on your Windows 10 computer. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” which could help you resolve the problem.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 4 – Troubleshot the problem in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing the Black border issue. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• 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.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

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.

Error Code 0x8007267C – What is it?

Error code 0x8007267C is specific to Windows 10. This error is triggered when no DNS server is currently configured in your network settings during the Activation process. If you are fairly confident in your ability to address command-line tools and networking issues, you can follow the steps below to try to remedy the error code on your own. If not, you may need to contact a qualified technician in order to resolve the error successfully.

Solution

Error Causes

The cause of Error Code 0X8007267C within the Window 10 system is fairly straightforward. Windows Activation requires a valid DNS server to be configured in order to complete the Activation process; if one is not available or properly configured, then you may see this error code and Activation will fail.

Further Information and Manual Repair

The following methods may help you to resolve this error, but you’ll need to have some familiarity with command-line tools to complete the steps successfully. If these methods do not work or if you are uncomfortable in using the command prompt, you may need to consult a technician to fully resolve this particular error code on the Windows 10 system.

Method 1: Register a DNS server within your network properties and test the connection.

In order to resolve this error code, client connectivity to a DNS server must first be established. The following steps may help you to determine the root problem with your connectivity status:

1. Open a command prompt, after which you'll run IPCONFIG /all
2. Verify the following values: The IP address that has been assigned, the DNS server, the subnet mask, and the default gateway. Compare each to ensure that all are set with the values that correspond to your specific environment
3. Check for basic IP connectivity to the DNS server using the PING command. In using the PING command, utilize the address of the DNS server found in Step 1

ping <DNS Server IP address>

If basic connectivity to the DNS server in question is failing, then you will need to resolve that issue before going further in the process.

After troubleshooting the above basic connectivity issues to the DNS server, you can reattempt Windows Activation by using the command below from within an Elevated Command selection:

cscript windowssystem32slmgr.vbs -ato

If the steps above did not work for you, you may want to try the steps found in method 2.

Method 2: Use phone-based authentication with a MAK (multiple activation key).

If a DNS server is not connected to your network, you can use an alternative method to complete the Windows Activation process. Bypass Method 1 by using a MAK product key instead to activate the volume license installation. Certain MAK product key providers have a variation on the specific key numbers that you will need to use. If you are using TechNet media or MSDN media, you will have to change the product key listed to the product key provided. The product keys provided by either TechNet media or MSDN media for Windows Server 2008 or for Windows Vista Enterprise will be the MAK product key that you will enter in a later step.

Like the previous method, you will need to have some familiarity or confidence in your ability to operate Command Line tools before proceeding. Once you have found your MAK product key, you’ll need to open a command prompt and use the following command to change the product key to match the MAK product key, which should look something like the example below:

            slmgr –ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

After completing the product key change, use the following command to initiate the phone activation wizard, thereby completing the activation of the system:

            slui 04

The activation wizard should be able to walk you through the remainder of the process in a step-by-step manner. In addition to appearing as an error code in Windows 10, this particular error may apply to multiple versions of Windows, including:

• Windows 7 Enterprise
• Windows 7 Enterprise E
• Windows 7 Enterprise N
• Windows 7 Professional
• Windows 7 Professional E
• Windows 7 Professional N

Steps to address the error code may be different in any of these other versions of Windows. If you have difficulty in resolving the error effectively, seek professional technical help.

intel's first gaming card that will hit the market soon has been shown in its innovation event, the Intel Arc A770. In its core ticks ACM-G10, coming with 32 Xe-cores and all the way up to 16GB of GDDR6 memory (the basic entry-level version will have 8GB of GDDR6). The card will support ray tracing and supersampling with Intel's XeSS.

This is Intel's first gaming desktop GPU and after testing with some YouTube channels it turned out that the card itself sits somewhere between nVIDIA RTX 3060 Ti and an RTX 3070 so it will still be low in performance compared with the new RTX 4090 or AMD's new RDNA3 upcoming lineup. But as stated this is Intel's first gaming graphics card and having this kind of performance is no small feat for the first-time product.

One thing that is really great tho and that is going for Arc A770 GPU is its price! The Limited Edition card will cost $329 which is at this moment most cheapest GPU currently on the market in that performance range. nVIDIA is between $500 and $700 for comparison and if Intel can hold on to its performance with almost half the price card could be a great hit among gamers. GPU itself will launch on October 12th.

If you suddenly encounter the SYSTEM_PTE_MISUSE – 0x000000DA Blue Screen error while using your Windows 10 computer, read on as this post will provide you some potential fixes to resolve this kind of Blue Screen of Death (BSOD) error. There are many potential causes for the SYSTEM_PTE_MISUSE – 0x000000DA BSOD error. However, incompatible hardware detection and hardware recognition failure are some of the topmost culprits. Another thing that could trigger this kind of BSOD error is system file corruption which means that if a system driver for particular hardware ends up getting corrupted, it won’t be able to recognize the external device and will eventually crash the system with the SYSTEM_PTE_MISUSE – 0x000000DA Blue Screen error. The SYSTEM_PTE_MISUSE bug check has a value of 0x000000DA which indicates that a page table entry or PTE routine has been improperly used. To fix this error, here are some suggestions that might help but before you get started troubleshooting the problem, make sure that you create a System Restore Point first.

If you are trying to update or upgrade your Windows 10 computer using the Windows Update and suddenly an “Error 0x800f0900” appears, then you’ve come to the right place as this post will help you resolve this Windows Update issue. When you encounter this error, you will see the following error message on your screen:

“There were problems installing some updates, but we’ll try again later. If you keep seeing this and you want to search the web or contact support for information, this may help: 2018-03 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4088776) – Error 0X800F0900”

This kind of Windows Update error is most likely caused by some corrupted files in the system. It is also possible that the Windows Database might have become corrupted as well. So if you are currently experiencing this problem, refer to the options given below and see which one of them works best for you.

Option 1 – Try running the DISM Tool

Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt as admin.
• Then type in this command: exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

After you run this tool, a log file is created at C:WindowsLogsCBSCBS.log. On the other hand, if the Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or use a Windows side-by-side folder from a network share, as the source of the files. Although the chances of this happening are less, if it turns out to be the case, you need to run an advanced command in the DISM tool to repair a broken Windows Update. Just repeat the process above but use the following command instead:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Option 2 – Try running the System File Checker or SFC scan

The SFC scan or System File Checker is a built-in command utility in Windows that helps in restoring corrupted files as well as missing files that cause several issues in the computer like the Windows Update Error 0x800f0900.

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 3 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update error 0x80073712. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 4 – Perform a System Restore

You can also try to perform a System Restore as it can also help you fix the Windows Update Error 0x800f0900. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap 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.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 5 – Reset both the SoftwareDistribution and Catroot2 folders

You have to stop a couple of services such as BITS, Cryptographic, MSI Installer, and Windows Update Services. And to do that, you need to flush the contents in the SoftwareDistribution folder. The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.

If you suddenly encounter Activation Error codes such as 0xC004E016, 0xC004F210, 0xC004F034, and 0xC004F00F on your Windows 10 computer, then they all point to the same issue – Invalid Product Key or Version mismatch. When you see any of the aforementioned error codes above, it indicates that you are either entering a wrong product key or you are using an incorrect ISO when installing it on your computer. In such cases, you may see either of the following error messages:

“You are running Windows 10 Pro, but you have a valid digital license for Windows 10 Home.” Or: “The specified product key is invalid or is unsupported by this version.”

If you got the error code 0xC004F00F then it means that you’ve entered a product key for the Enterprise edition of Windows to activate Windows 10 Pro or Windows 10 Home. It could be that you have a key from your work and you accidentally use it on your Home PC. If you got the error codes 0xC004E016, 0xC004F210, then it means that you have entered a product key that is meant for a different edition or version of Windows. On the other hand, if you got the error code 0xC004F034 instead, then it means that you have entered an invalid product key or a product key for a different Windows version. Whichever error codes you have, refer to the possible solutions given below to fix the Invalid Product Key or Version mismatch Activation Error in Windows 10.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve this Activation error is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

Option 2 – Try purchasing a new license

There is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect to your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

Option 3 – Try activating Windows 10 via mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.
