Fix Realtek HD audio driver issue

Recently, a number of users reported not being able to use the Restore, Minimize and Close buttons on their Windows 10 computers. This kind of issue can be quite annoying as you won’t be able to use your computer properly, especially when you navigate between programs and windows. In such cases, the buttons on the right side of the title bar won’t respond to any inputs which could be caused by a number of factors such as different input modes, corrupted system files, and many more. If you are one of the users who are currently facing this problem, worry not for this post will guide you on what you can do to resolve it. There are several potential fixes you can check out to fix the issue. You can try to check if Tablet Mode is enabled and if it is, you have to disable it. You could also boot your computer in a Clean Boot State to check if a third-party program is the one that’s causing the problem. In addition, you could also reinstall the program where you experience the problem or run built-in utilities like System File Checker and DISM tool.

Option 1 – Make sure that you are not in Tablet Mode

Since Windows 10 is designed to work on both desktop and mobile devices, it could be that your computer has slipped into Tablet Mode which explains why you’re not seeing the Taskbar. To check if your computer is really in Tablet Mode, follow these steps:

• Go to the Start menu and select Settings.
• Next, select the System setting and from the left pane select the Tablet Mode.
• From there, make sure that the buttons next to the options given below are set to the off position:
  • Hide app icons on the taskbar in tablet mode
  • Automatically hide the taskbar in tablet mode

Option 2 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into 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.)
• Once your computer is in a Clean Boot State, try to open the program where the problem occurred.

Option 3 – Try reinstalling the program

If the first two options didn’t work, then you might want to consider uninstalling the program and then install it back with its latest version. This should resolve the problem.

Option 4 – Try to run System File Checker

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be the cause why the Restore, Minimize and Close buttons don’t work. To run the SFC command, follow the steps given below.

• Type “cmd” in the Start search and then right-click on the appropriate search result.
• Next, select “Run as administrator” to open Command Prompt with admin privileges.
• After opening Command Prompt, type in sfc /scannow

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.

• Now restart your computer and see if the problem is fixed or not.

Option 5 – Run the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the problem. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• 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. Once it’s done, restart your computer.

Qtcore4.dll Error - What is it?

Qtcore4.dll is a dynamic link library file that helps Microsoft Windows in loading several key components of the system. The Qtcore4.dll error occurs when the Qtcore4.dll file cannot be loaded to run the application supported by this .dll file. The Qcore4.dll missing error message may occur while booting your system or launching a certain program. It is a blue screen of death error type. The Qtcore4.dll error code is often displayed as:

BLUE SCREEN ERROR - QtCore4.dll Not Found

Solution

Error Causes

This error code is triggered by a variety of reasons such as:

• Windows file allocation file gets damaged
• Your computer BIOS (Basic Input/Output System) are misconfigured
• The Qtcore4.dll file gets corrupt
• Registry gets damaged and corrupt
• Non-Microsoft program not running in tandem with Windows
• Malware attack
• Improper hardware driver software

It is advisable to fix the Qtcore4.dll error code immediately as this error can pose serious threats to your system. Qtcore4.dll error can lead to system breakdown.

Further Information and Manual Repair

Here are some ways of fixing the Qtcore4.dll error on your system:

1. Re-install the Program Causing Qtcore4.dll error message to pop up

As dll files are shared files sometimes due to program deletion and installation .dll file settings can get misconfigured, damaged, and corrupt. In such a scenario, you can try reinstalling the program that is causing Qtcore4.dll error message to appear on the screen.

2. Reconfigure your Mis-configured BIOS

If BIOS misconfiguration is the cause of this error code on your system, then try reconfiguring your system’s misconfigured BIOS.

• To do this boot the computer and then press the BIOS designated keys to enter the BIOS. The keys may vary from manufacture to manufacture but typically, the setup keys are F2, F10, F12, and Del.
• Once you figure out the setup keys, press them rapidly when booting the computer.

For more information, refer to each one of the options given below.

Option 1 – Try restarting your computer and run the SFC again

The first thing you can do to fix the problem is to restart your computer and let the pending process be completed. After your computer restarted, try to run System File Checker again and see if the error is now fixed or not. If not, refer to the other options below.

Option 2 – Try deleting the pending .xml file

The next thing you can do to fix the problem is to delete the pending .xml file. How? All you have to do is navigate to this location at CWindowsWinSxS and from there, look for a pending .xml file and rename it or delete it. This will get rid of any pending tasks and will build a fresh new check.

OneXPlayer is a direct competitor to Valve’s upcoming steam deck. This device is clearly inspired by Valve’s offering and it shows all over the place, from its looks to its purpose and aims to PC gamers as a handheld device.

Hardware under the hood

This device is packing a 7-inch 1080p display, 11th generation Intel Core i7-1195G7 CPU, stunning 16GB of RAM, 512GB SSD drive with the option to purchase 1TB or 2TB model. GPU of choice is Intel iris Xe Graphics that is in our opinion a bottleneck in the whole system and for more demanding games, we believe switching them to 720p would be a better option. Everything here is powered with a 10455 mAh lithium-ion battery.

OneXPlayer inputs and other stuff

Handheld is equipped with dual bumpers and dual linear triggers. The console comes with dual speakers on both sides of it. Inside the console, there is an aluminum heat sink with copper heat pipes and a fan in order to cool internal hardware. On the outside, we have two USB-C ports and one USB-A port for connections, and of course, a headphone jack for headphones. The console comes with Wi-Fi 6 and Bluetooth 5.0 for wireless connectivity.

Price

The base entry model will cost you a whopping $1.259, 1TB model $1.399 and 2TB one will go as far as $1,599. With this kind of price, I am not sure it can come up as a winner against Valve. Sure it is packing fully licensed Windows 11 that will for sure offer more options than Stem’s OS based on Linux but even with that advantage I do not think it justifies such a big price difference.

Conclusion

Of course, this kind of console or handheld PC will still find its customer base, many users will probably like it since it comes Windows ready out of the box. Sure, you can place Windows on Steam deck as well but you will need to know how, where everything is ready and you can run beside steam other launchers without issues like origin, uplay, gog, etc. How this will be accepted by community time will tell but it is good to see that there is variety and competition in handheld PC space.

There are times when you try to open a file, an executable file for instance, but were unable to do so since you encounter an error in an Open File – Security Warning dialog box that says, “This publisher has been blocked from running software on your machine, You must unblock this publisher to run this software”. This kind of error is most likely thrown by your operating system because it considers the file to be unsafe and could potentially harm your computer. However, if you’re certain that the file is harmless, read on as this post will walk you through fixing the error so you can open the file without getting an error. There are various options you can check out to fix the error. You may run the program using Command Prompt or unblock it using File Properties. You could also try turning off SmartScreen or use the unblock file command in Windows PowerShell.

Option 1 – Try running the program via Command Prompt

• Tap the Win + R keys to open the Run dialog box and type “cmd” in the field and hit Enter to open Command Prompt.
• Next, tap the Shift key and right-click on the program or the executable file, and then select the “Copy as path” option.
• After that, paste this path in the Command Prompt window and tap Enter to open the program.

Option 2 – Try to unblock the file using File Properties

• Right-click on the file you were trying to open and select Properties.
• Next, click the Unblock button and then click on the Apply and OK buttons.
• You should now be able to open or access the file without getting the error.

Option 3 – Turn off SmartScreen

The next thing you can do is to turn off SmartScreen temporarily. All you have to do is open the Windows Defender Security Center and from there, go to the App & browser control section. After that, click on the radio button for Off under Check apps and files. Once you’re done, try opening the file again. Don’t forget to enable the SmartScreen back on.

Option 4 – Try to use the Unblock-File command in PowerShell

You might also want to utilize the Unblock-File command in Windows PowerShell as it will unblock the file so you can open it. To execute this command, follow these steps:

• Tap the Win + X keys and then click on Windows PowerShell.
• After opening PowerShell, type or copy and paste this command and tap Enter to execute it: Get-ChildItem -Path 'C:Users<username>Downloads' | Unblock-File
• The command you entered will unblock all the files in the Downloads folder, assuming that’s where the file you were trying to open is stored. If it’s not, then replace the path with the path where the file is located. Take note to also replace “<username>” with your Username.
• Now check if the file has been unblocked by accessing or opening it.

The Windows Defender program can both scan and monitor almost the entire folder on a Windows 10 computer. So if you have a folder that may have files that could trigger an alarm to Windows Security, then it would be better if you add an exclusion to Windows Security. Note that it is okay to do this as long as you’re certain that the contents of the folder you want to exclude are safe and that Windows Defender is only throwing out warnings for nothing. This way, Windows Defender won’t scan those folders in the future. And besides, there are also some Windows folders and files that you may exclude from the Antivirus scans, especially if you want to save your scan time. This kind of feature also comes in handy when you trust a file type or folder or any process that you believe is safe but the Windows Security considers as malicious. To exclude a folder or a file or process or a file type from the Windows Security scan, here are some steps you can follow. Make sure to do them carefully. Step 1: Search for “Windows Security” in the Search box and then click on it from the search results to open it. Step 2: Next, click on Virus & threat protection > Manage settings > Add or remove exclusions. Step 3: After that, on the next screen, click on Add an exclusion > Folder. It will show you a list that includes File, Folder, File Type, and Process. Step 4: Now click on “+Add and exclusion” on the next window and then select a folder you want to exclude and click OK to add it in the Exclusions list. Step 5: Click on the down arrow button to remove it and then click on the Remove button. Note: If you want to only ignore a few file types, it’s better if you configure your antivirus program to ignore these files with a specific extension. This way, it will ignore all of them no matter what their location is. Also keep in mind that when you select a folder, all the subfolders in it will also be excluded from the scan. Thus, you need to understand what you’re about to do. Once you’re done excluding the folder, it is recommended that you protect the folder using the Controlled Folder Access since this folder is not monitored for threat. The Controlled Folder Access will ensure that an external program does not alter it. This way, you can be sure that even though this folder is not included in the scan, it is still secure.

If Error Code 0xc00000e9 appears on your screen, there is no cause to panic yet as there are different ways to fix this. Here, I will list down different methods to get your computer back on track:

1. Check peripheral connections
2. Check your SATA cables
3. Check your hard drive
4. Check your BIOS settings

Quick Fix 1. Check Peripheral Connections

1. Turn off your computer.
2. After the computer has been shut down, take off all the peripherals or the USB cables that are connected to your USB ports. This includes even the keyboard and the mouse. We just need to have only the monitor plugged in for this one.
3. Turn on your computer and see if it starts as it normally does.
4. If it does, try connecting back your external devices or peripherals one by one until you find the one that causes the error.
5. Once you trace the device that’s causing the error, you will have to change its USB cable and update its driver to support your operating system.

Quick Fix 2. Check your SATA cables

It is possible that what causes a barrier between your operating system and your hard drive from communicating is the SATA cable used. For example, if you’re using an older SATA with a SATA III port, there might not be adequate support for the transfer of data from one another. Or, the problem might be a loose SATA cable which would still require you to buy a new one to replace your loose or damaged cable. To check if your SATA cables are causing the error, simply follow these steps:

1. Turn off your computer.
2. Carefully open its case.
3. Check the hard drive and the SATA port where it’s connected.
4. Try to use a newer cable and connect it to your SATA port. (If you used a SATA II cable, you can see if a SATA III cable is more compatible.)
5. Replace your SATA cable with a newer one if Step 4 proves to be successful.

Quick Fix 3. Check your hard drive.

1. Try to use a different hard drive and see if error code 0xc00000e9 still appears.
2. If it works out just fine, then the problem might be physical damage to your hard drive and would need to be repaired depending on the case. Just simply take it to a technician and let him know about the issue.

Quick Fix 4. Check your BIOS settings

1. Restart your computer.
2. Once your computer starts, press and hold the ESC, F2, F12, or DEL key to go to BIOS settings.
3. You will then be redirected to the BIOS Setup Utility screen. From here, go to Boot options.
4. In the Boot Options, see if your first boot device is your hard drive. If it isn’t, press the arrow key to select the hard drive and move it to the top of the boot device list.
5. Save the settings.
6. Reboot your computer.

Note: If all the methods above do not work, the problem might be on your drivers and you might need to update them. You can update your driver in two ways: Manual driver update and Automatic driver update. You can find procedures online in updating your drivers.
