Fix Failed to play test tone Error in Windows

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

If the VIDEO_SCHEDULER_INTERNAL_ERROR BSOD error is still not fixed after System Restore, then follow the given options below to further troubleshoot the problem.

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

Since the VIDEO_SCHEDULER_INTERNAL_ERROR Blue Screen error has something to do with Graphics card drivers, you can either roll back, update or disable them depending on your preference in order to resolve the error.

• 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 Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters 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 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.
• From there, look for any faulty drivers. You can identify them easily as they will be marked with a yellow exclamation point. And then check which entries would not affect the normal functioning of your PC.
• Now click on the entries of every faulty driver and click on the Uninstall option.
• 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.
• After opening Command Prompt, type the “sfc /scannow” command and hit Enter to run the System File Checker scan.
• Wait until the process is completed and type “exit” to close Command Prompt and then restart your computer to successfully apply the changes made.

Option 6 – Try to run the Blue Screen Troubleshooter

As you know, the Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like the VIDEO_SCHEDULER_INTERNAL_ERROR error. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.

‘R6025 pure virtual function call’ is a runtime error that occurs suddenly on the screen and disrupts the program being run prior to it. This error display indicates that the program has been corrupted. R6025 runtime error usually occurs with the Visual C++ framework.

Solution

Error Causes

This error occurs when the C++ program crashes which is usually because of the malfunctioning or missing of the device driver or incomplete device driver files. It happens because your application indirectly calls a pure virtual member function in a context where a call to the function is invalid. Most of the time, the compiler detects it and reports it as an error when building the application. R6025 error is usually detected at run time.

Further Information and Manual Repair

To fix the R6025 pure virtual function call error, you need to find the call to the pure virtual function. After you find the call, you need to rewrite the code so that it is not called again. There are 2 ways to do this:

Alternative 1

One way to fix the R6025 pure virtual function call is to replace the function with an implementation that calls the Windows API function DebugBreak. The DebugBreak causes a hard-coded breakpoint. Once the code stops running at this breakpoint, it is easy for you to view the call stack. By viewing the call stack you can identify the place where the function was actually called.

Alternative 2

Another quick way to find a call to a pure virtual function to fix the R6025 error is to set a breakpoint on the _purecall function that is usually found in PureVirt.c. By breaking this function you can trace the problem occurring and rewrite the call to ensure the error does not occur and the program you are trying to develop on the Visual C++ framework is easily developed. If R6025 Error is related to Windows Registry Problem Then here’s how you can fix the problem: To fix the runtime error R6025, run registry cleaner software to scan and fix all errors.  This alternative is suitable if the R6025 error is related to the Windows registry problem and where the error has occurred due to corrupted or malicious registry entries. You can download the registry cleaner repair tool for free. Run it to scan errors and then click the fix error button to repair the problem immediately.

ChatZum is a Potentially Unwanted Program that installs a Toolbar into your browser. This program allegedly allows users to zoom in on photos without clicking on them, however, upon further research, it was discovered that this function does not work on the latest version of browsers.

From the Author: ChatZum is a Browser add-on (toolbar) that enables its users to hover over images in Major Social network's websites and view a larger version of an image.

While installing this toolbar will track user web browsing sessions and will record website visits, clicks, and sometimes even personal information. This information is later used to display targeted ads to the user. To allow easier user tracking, the program changes the browser home page and default search engine to Nation Search Advanced, which injects additional advertisements and tracks user activity.

Several anti-virus applications have marked this program as Potentially Unwanted, and it is not recommended to keep it on your computer, especially considering the fact it will most likely not work on your browser.

About Potentially Unwanted Applications

If you have ever installed a free application or shareware, chances are high that the computer will get installed with a bunch of unwanted applications. A Potentially Unwanted Program, also called PUP, in short, is actually software that contains adware, installs toolbars, or has got other hidden objectives. These types of programs are generally bundled up with a free application that you download from the internet or may also be bundled inside the custom installers of many download websites. PUPs aren’t always viewed as “pure” malware in the strictest sense. A fundamental difference between PUP and malware is distribution. Malware is normally dropped by silent installation vectors like drive-by downloads while PUP gets installed with the consent of the computer user, who knowingly or unknowingly approves the PUP installation on their computer system. But, there is no doubt that PUPs remain bad news for PC users as it could be quite dangerous to your computer in many ways.

The damage PUPs can do

The unwanted programs after installation display numerous annoying pop-up ads, trigger fake alerts, and sometimes even forces a computer owner to pay for the software. PUPs that come as browser add-ons and toolbars are commonly recognizable. These toolbars alter your homepage and your search engine in the installed web browser, track your web activities, modify your search results with redirects and sponsored links, and eventually slow down your browser and diminish your browsing experience. Potentially unwanted programs use aggressive distribution methods to get onto your computer. The worst part of setting up a PUP is the adware, spyware, and keystroke loggers that could lurk inside. Even if the PUPs really aren’t inherently malicious, these applications still do practically nothing good on your PC – they’ll take valuable system resources, slow down your PC, weaken your computer security, making your PC more vulnerable to malware.

How to avoid ‘crapware’

• Read the EULA thoroughly. Look for clauses that state that you have to accept advertising and pop-ups or bundled applications from the company. • Always opt for the custom if you’re offered an option between “Custom” and “Recommended” Installations – never ever click Next, Next, Next thoughtlessly. • Use a good anti-malware application. Try Safebytes Anti-malware which can find PUPs and treat them as malware by flagging them for deletion. • Be alert if you download and install freeware, open-source applications, or shareware. Do not ever install software applications that seem shady or malicious. • Always download applications from the original website. The majority of PUPs find their way onto your laptop or computer is via download portals, so steer clear of it altogether. Remember the fact that even though PUPs could potentially cause damage and hinder the proper functioning of the PC, they can’t enter into your system without your consent, so be alert not to provide them with it.

You might also want to reset your home page and search providers, as well as delete browsing history, temporary files, and cookies. If you choose to manually remove the system files and Windows registry entries, use the following list to make sure you know exactly what files to remove before undertaking any actions. Please note that only advanced users should try to manually edit the system files mainly because removing any single vital registry entry results in a serious problem or even a PC crash. In addition, certain malware is capable of replicating itself or preventing its removal. Doing this malware-removal process in Safe Mode is recommended.

Encountering errors is never a pleasant experience and fixing errors can sometimes take a large amount of time. Also depending on your expertise and knowledge about computers and the operating systems themselves could be determining factor would you try to wrestle with error.

We will explore and analyze the advantages of both methods so you can choose and know when to apply one and when to reach for the other.

Advantages of manual method

Full control is the main advantage of manually solving errors, when you go deep dive into manually fixing problematic issues you are one that has control. Complete freedom is also another, sometimes fixing things can be done in several different ways and when you are the man behind the wheel, you are the one that can choose how to approach and what solution to apply in order to solve the issue.

Disadvantages of using manual method

The main disadvantage that some users might encounter is that they will need to know ins and outs of computer and operating systems' workings. Of course, the more complicated errors, the more knowledge it will require in order to apply the proper fix. There is also a risk to break something else if the person that is doing the fixing is not fully competent so this is also something to think about.

Another thing that goes against manual fixing is the time it will require in order to actually fix it, some more complex stuff will probably depend on searching for some external resources like searching for compatible drivers for example, or navigating complex registry keys inside Windows.

Advantages of automatic solutions

If you are a user that has no knowledge about how the operating system works, if you do not know what is a registry or how to properly navigate through the Windows folder then the automated solution is for you. The main advantage of automated systems is that you can easily fix errors without any kind of technical knowledge and usually with just one click of a button.

Saving time is also one of the advantages of fully automated solutions because they will work much faster than manually locating the problem and then fixing it. Also, most of these systems will have in place active monitoring that will check always if your system is in top form and alert you when something is not right.

Disadvantages of one-click solutions

Automated solutions are great, they can solve various issues and errors without any knowledge from the user, but they are not perfect. Like security suites sometimes an automated system can misinterpret something as an error when in fact it is not and fixing it could mean some apps not working anymore, luckily you can choose would you like to apply the suggested solution. So if you are using one do not just click fix without looking at what it is trying to fix and maintain.

Another problem with this is the price it is carrying, manually solving your computer error will cost you your time and knowledge but good automated software will come with a price tag. Some people might not be too happy to pay for this kind of application but at the end of the day, it will still be cheaper than a professional technician. The last thing that you should be aware of is that in order for the app to do its work properly it will need to be active all the time, now for modern computers, this is not the issue but for some older ones with a small amount of memory might lead to some slowing them down. This is a price to be paid in order to have your system always errors free.

Should you use an automated solution at all?

This depends on your knowledge and time available, professional IT technicians will not need this type of solution nor will power users but for most common people this will offer computers free of errors for an affordable price.

Upgrading your Windows computer may not always go as expected as you could end up getting some error messages along the way. One of the error messages you can encounter is the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. This error indicates that is some security issue within the Windows operating system. It could be that the system files have an issue and they have been modified incorrectly. Although this does not necessarily mean that malware is behind the modification, one of the applications you installed recently might have something to do with the problem. The application might have modified or corrupted some of the core system files. When you encounter this error, you will see a blue screen along with the following error message:

“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. (0% complete) If you’d like to know more, you can search online later for this error: 0xc000021a”

This error pops up when a user-mode subsystem like the WinLogon or the Client Server Run-Time Subsystem or CSRSS has been compromised fatally and security can no longer be guaranteed in the system. Thus, the operating system switches to kernel mode, and Windows won’t be able to run without the WinLogon or the Client Server Run-Time Subsystem. This is why it’s one of the few cases where the failure of a user-mode service can shut down the system. To resolve the issue, here are some fixes that might help.

Option 1 – Uninstall programs you installed lately

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the concerned program and select it and then uninstall it.

Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it.

Option 2 – Perform System Restore

Performing System Restore can also help you fix the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. 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 3 – Run the System File Checker or SFC scan

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 you’re getting the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• 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.

Option 4 – Rebuild the BCD and fix MBR

Rebuilding the BCD can help you in fixing the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error.

• You can start by booting into the installation environment for Windows 10 from an installation media.
• After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
• Next, select Command Prompt and type in the commands below one by one, and tap Enter right after you do so.
• exe /FixMbr
• exe /FixBoot
  • exe /RebuildBcd

The commands you entered should rebuild the BCD and repair MBR.

Option 5 – Run the CHKDSK utility

You can also run the Chkdsk utility to resolve the problem. 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 commands listed below, and don’t forget to hit Enter right after you type in each one of them.
• chkntfs /t
• chkntfs /t:10

One of the primary packages that install the Windows Media Player is the Media Feature Pack among other related files that are needed by the associated software products. And one of the essential DLL files in that package is the mfplat.dll file which is needed by various games and streaming services. So if this DLL file goes missing, you will most likely encounter any of the following error messages:

• “mfplat.dll missing”
• “The application failed to start because mfplat.dll was not found.”
• “The program can’t start because mfplat.dll is missing from your computer.”

In other circumstances, the Media Feature Package does not come pre-installed with the main Windows package especially for those who use Windows N, thereby causing the error to pop up. The main cause of this problem is that users who use Windows 10 N do not have the Media Feature pack pre-installed with the installation package. Aside from that, the installation package could go missing after a few Windows Updates or if you have uninstalled it by accident. To resolve this problem, you need to check out each one of the given options below.

Option 1 – Try to enable Media Playback via Command Prompt

If you encounter the mfplat.dll missing error when you attempt to run PLEX or other similar streaming service and you’ve already verified that the Media Feature Pack is indeed installed, you might want to try enabling it using an elevated Command Prompt. There are cases when a particular Windows Update ends up disabling the feature and creates the grounds which results in the mfplat.dll missing error. Thus, you can have to enable the feature via Command Prompt.

• Tap the Win + R keys to open the Run dialog box.
• Then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
• Next, click on Yes if a User Account Control prompt pops up.
• After opening Command Prompt, copy and paste the following command and hit Enter to execute it:

dism /online /enable-feature /featurename:MediaPlayback

• Close Command Prompt and then open the app once again to check if the problem is now fixed.

Option 2 – Try installing the Media Feature Pack for Windows 10 N version

As mentioned, the Windows 10 N version does not come with Windows Media Player. Meaning to say, the Media Feature Pack is also not installed by default or won’t be updated by the Windows Update component. So if you are not quite sure what Windows 10 version you currently have installed, refer to these steps:

• Tap the Windows key + S and then type “about” in the search box.
• From the search results, click on the “About your PC” to open the About tab of the Settings app.
• Afterward, scroll down to the Windows specifications and check your Windows version under Edition.

Note: If you have verified that your PC is using the Windows 10 N version, you need to install the appropriate Media Feature Pack for your computer. How? Refer to the steps below:

• Click this link to download and install the Media Feature Pack from Microsoft’s official website.
• Upon installation, select the edition you want to install using the drop-down menu and then click on Confirm. Take note that there are few reasons why you’d want to install the older version since most streaming services like PLEX and most games usually require version 1803.
• After that, wait until the request is validated. The download should begin in a few minutes automatically.
• Once the download is completed, open the installation executable file and follow the next on-screen instructions to install the Media Feature Pack on your computer.
• Restart your computer. After your computer has rebooted, open the application where you’re getting the mfplat.dll missing error and then check if the problem is now fixed.

Option 3 – Try to extract a copy of the mfplat.dll file from the windows.old directory

If you encounter the error shortly after you just upgraded to Windows 10 from an older version, the best thing you can do to resolve the problem is to use windows.old directory to fetch an old copy of the mfplat.dll file. To do so, follow the steps below.

• Go to the Windows drive and then look for the windows.old directory where it preserves a copy of your old operating system as well as associated files in case something goes out of hand during the upgrade process.
• After that, open the windows.old folder and then go to the syswow64 folder.
• Next, from the syswow64 folder, copy the mfplat.dll file and paste it to C:/windows/syswow64.
• Restart your computer and check if the error is now resolved or not.

You will notice the blurred background on the login screen right away when you start your Windows 10 computer that’s running the v1903 and up. This kind of blurred background is known as “Acrylic Blur Effect on Sign-in Screen”. This new feature delivers a beautiful experience to users by adding more focus to the login screen. However, no matter how nice this feature is and even if it only stays for less than a minute, not all users like it and if you’re one of these users, read on as this post will guide you in disabling the blurred background login screen in your Windows 10 computer. Disabling the blurred background in the login screen can be done in two methods. The first one is via the Registry Editor and the second one is via the Group Policy Editor. Before you proceed, make sure that you are using an admin account and you must create a System Restore point first. Once you have that covered, follow the options provided below.

Option 1 – Disable the Blurred background in the login screen via Registry Editor

• First, tap the Win + R keys to open the Run dialog box and type “Regedit” in the field, and hit Enter to open the Registry Editor.
• After that, navigate to this registry path: KEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsSystem
• Next, right-click on any empty space in the right pane and create a new DWORD (32 bit) and name it as “DisableAcrylicBackgroundOnLogon”.
• Once you’ve created the DWORD, double click on it and set its value to 1 to disable it and 0 to enable it.
• After you make the necessary changes, restart your computer. You won’t now see the blurred background on the login screen.

Note: No matter what option you select to change the background, it will stay blurred when you click on the login button. At the time of writing, there is no way to disable this feature in the Personalization section so the Registry Editor will have to suffice for now.

Option 2 – Disable the Blurred background in the login screen via Group Policy Editor

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
• After that, navigate to this policy setting: Computer ConfigurationAdministrative TemplatesSystemLogon
• From there, double click on the “Show clear logon background settings” and since its default value is “Not configured”, set it to “Disabled”. You will see the following description under this setting:
  • “This policy setting disables the acrylic blur effect on the logon background image.”
  • “If you enable this policy, the logon background image shows without blur.”

• Now click on OK and then check the login screen.

Note: If you don’t configure or if you disable this policy, the logon background image adopts the acrylic blur effect. However, if it didn’t work, you have to restart your computer and then check.

About Browser Hijackers

Browser hijacking means a malicious program code has taken control over and modified the settings of your browser, without your permission. Browser hijackers will do a number of things on a computer. These are typically used to force visitors to a particular site, manipulating web traffic to earn ad revenue. It may appear naive, but the majority of these sites are not legitimate and may pose a serious threat to your online safety. They did not just screw up your web browsers, but browser hijackers can also modify the system registry, leaving your computer susceptible to other attacks.

How you can determine if your browser is hijacked

When your browser is hijacked, the following could happen: home-page is changed; you see new unwanted favorites or bookmarks added, usually directed to advertisement-filled or pornography sites; the default browser settings are changed and/or your default web engine is altered; you find unsolicited new toolbars added; never-ending pop-up adverts appear and/or your web browser pop-up blocker is disabled; your web browser starts running slowly or exhibits frequent errors; you can’t visit specific websites like home pages of security software.

Precisely how browser hijacker infects computer systems

Browser hijackers could use drive-by downloads or file-sharing websites or perhaps an e-mail attachment in order to reach a targeted computer. They may also come from any BHO, browser extension, add-on, toolbar, or plug-in with malicious intent. A browser hijacker can be installed as a part of freeware, shareware, demoware, and fake programs. A good example of a well-known browser hijacker is the latest Chinese malware called “Fireball”, which has infected 250 million PCs across the world. It works as a hijacker but can be turned into a fully functioning malware downloader afterward. The existence of any browser hijacker malware on your system could substantially diminish the web browsing experience, monitor your internet activities that lead to serious privacy concerns, create system stability problems and ultimately cause your PC to slow down or to a nearly unusable state.

At times, it could be a tough job to find and eliminate the malicious program since the associated file could be running as part of the operating system process. Also, manual removals require in-depth system understanding and thus can be a very difficult job for novice computer users. Browser hijackers could be effectively removed by installing and running an anti-malware program on the affected PC.
