Windows 10 won't upgrade to a newer version

‘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.

Since the Windows 10 operating system has the Playing Audio Troubleshooter, you can use this troubleshooter to try and fix the problem with the headphones. You can access this tool in the Control Panel or in the Taskbar Search and even on the Troubleshooters page of Windows 10. Run this troubleshooter and see if it can fix the issue or not.

Option 5– Try to rollback or install a newer Windows Update

As mentioned earlier, the issue with the headphones could be due to a Windows Update. Thus, to fix the problem, you can try to either roll back or install a newer Windows Update.

Error Code 7 - What is it?

This is a typical system error that occurs during Windows setup. To be precise, this error may pop on your computer screen during the text mode portion of Windows setup. The setup hangs and stops responding and the error message is displayed in either one of the following formats:

‘The file I386Ntkrnlmp.exe could not be loaded. The error code is 7.’ or ‘The file I386L_intl.nlf could not be loaded. The error code is 7.’

Solution

Error Causes

Error 7 may be triggered due to several reasons but the 2 most common causes for this error code are:

• Incorrect settings of the BIOS
• Faulty RAM modules
• Registry corruption

Further Information and Manual Repair

To resolve this error on your system, here are some easy and effective DIY methods that you can try.

Method 1 - Change Back the BIOS to its Default Settings

If the underlying cause of error code 7 is related to incorrect BIOS settings, then it is recommended to restore default settings to resolve. You can reset your computer’s BIOS (basic input and output system) settings to factory defaults by selecting the restore defaults option within BIOS or by removing CMOS ( Complementary Metal Oxide Semi-Conductor) battery from your unplugged computer for about five minutes. The battery removal method requires opening the computer case, so only attempt it if you are unable to access BIOS. To reset BIOS follow these steps, reboot your PC and then press the key assigned to loading BIOS during your computer boot splash screen. The key assigned to load and access BIOS varies from manufacturer to manufacturer but usually, it's F1, F2, or F12. Once you enter the BIOS, select the ‘Restore Defaults’ option listed in the menu.  I t may be a keyboard shortcut or be under the Advanced settings menu. Confirm settings and then exit BIOS. Hopefully, this will resolve Error 7.

Method 2 - Remove the Faulty RAM

When error code 7 is triggered by faulty RAM modules, then to resolve it simply remove the memory modules that are installed in the computer. If the error code is displayed again after you remove the memory module, remove a different memory module. This procedure requires you to reboot your PC several times to identify the specific memory module that is not working properly.

Method 3 - Repair the Corrupted Registry

Error code 7 is sometimes also linked with registry issues. If the reason for the error occurrence is a damaged or corrupted registry, then simply download Restoro. This is a powerful PC Fixer embedded with a registry cleaner. It is easy to operate and user-friendly. The registry cleaner detects and removes all errors in seconds. It cleans the registry and repairs the damages in no time. Click here to download Restoro.

If your Windows computer is not booting up and displays Secure Boot Violation – The system found unauthorized changes on the firmware, operating system, or UEFI drivers error message on the screen, then you can follow this tutorial to troubleshoot the problem. When you encounter this kind of problem on your computer, you will get the following error message on your screen:

“Secure Boot Violation The system found unauthorized changes on the firmware, operating system, or UEFI drivers. Press [OK] to run the next boot device or enter directly to BIOS Setup if there are no other boot devices installed. Go to BIOS Setup > Advanced > Boot and change the current boot device into other secured boot devices.”

This kind of error message pops up due to the Secure Boot that protects your computer from running any non-OEM signed boot software during startup. In other words, the Secure Boot firmware is the one that scans for non-signed boot software each time your computer boots up and if it detects anything strange, it will block the boot and will display the error message. To fix this error, there are two things you can try. You can try to disable the Secure Boot or try using a System Restore Point. For more detailed instructions, refer to each one of the options provided below.

Option 1 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the issue. To disable Secure Boot, here’s what you have to do:

• First, boot your computer into Windows 10.
• Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
• After that, go to the BIOS of your computer.
• Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
• Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Select the UEFI Firmware Settings which will take you to the BIOS.
• From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
• Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
• Save the changes made and exit. Afterward, your computer will reboot.

Option 2 – Try running System Restore in Advanced Startup Options

Since you probably can’t boot into your Windows 10 computer, you can try to run System Restore again in the Advanced Startup Options.

• Boot your computer into the Advanced Startup Options screen.
• From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
• Now select Troubleshoot > Advanced Options > Command Prompt.
• After that, type “rstrui” and hit Enter to execute the command which will start the System Restore process.

Option 3 – Make a proper bootable USB Drive/Stick

To make a proper bootable USB drive, you need to use the Windows Media Creation tool. The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

• After making the bootable drive, you need to plug it into your computer and then reboot.
• Next, tap the F10 or Esc key to open the boot options.
• Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

You left your computer to go to the bathroom or to fetch something to eat, maybe you have to answer the phone or open door to a friend and after some time you get back to your computer see the black screen, you move the mouse and it starts to come from sleep slowly. I am the kind of person who gets annoyed by this kind of behavior, I like my PC to be ON all time when I want it to be ON and my power plan on best performance so naturally, I have turned this sleep feature OFF. If you are interested to see how you to can turn off your screen sleeping follow this easy guide.

1. Press ⊞ WINDOWS to open the start menu and click on the settings
2. On settings, screen click on system
3. When the system dialog opens go to Power & Sleep and on the right side change all values to never.

Please note that after each update Windows tend to reset these settings so you will sadly have to return to this after each major update.

Interesting information has come out from Microsoft, Windows 11 dark theme will include a different sound theme from its standard light one. When in dark mode on Windows 11, the system sounds generally become softer, and they echo a bit, creating a more soothing experience that matches the overall look and feel of the dark mode. Flipping back to light mode brings the system sounds back to their normal level. However, even though the light model has slightly louder sounds than the dark mode, Microsoft has taken great care to make sure the audio is more soothing, according to a report from CNBC. The designers of Windows 11 took inspiration from an approach called calm technology. Microsoft’s Christian Koehn and Diego Baca wrote about calm technology in a post on Medium. In it, they said, “Windows 11 facilitates this through foundational experiences that feel familiar, soften formerly intimidating UI, and increase emotional connection.” According to a Microsoft spokesperson in a statement to CNBC, “The new sounds have a much rounder wavelength, making them softer so that they can still alert/notify you, but without being overwhelming.”

In the last article, we have covered various advantages of Apple hardware over Windows PC, however, PC has their own strengths and advantages over MACs as well. Join us as we explore why would you choose Windows PC over MAC.

Hardware customization

If you like to customize and build your own hardware and customize your existing computer then MACs are out of the picture, on other hand, computers based on Windows operating system are much more flexible in terms of customization.

While Apple hardware is locked and only allows small changes to it, computers running on Windows are free and open to various upgrades and modifications so if you like to play with hardware Windows is your platform.

Gaming

There are games on MAC true but their numbers can not compare to games available for the Windows platform. On top of that, most latest and best gaming hardware is not even available on Apple platforms so if you plan to game in high resolutions and play the latest games there really is no option other than Windows.

Windows Platforms also has multiple emulators that you can use to play games from other older platforms and Microsoft since it owns Xbox has some great plans for both PC and Xbox gaming.

Software back compatibility

Since the introduction of the new MAC OS X, apple really lost a lot of application back compatibility, and a lot of old legacy software can not be run on modern Apple computers. Windows on the other hand have always tried and succeeded in keeping maximum compatibility with older and legacy software.

Also on the Windows platform, there is a lot of community support for old and legacy software so even if it is not officially supported it is backed up by the community.

Software variability

In terms of where can you find the most different software, you need to look no further than the Windows platform. How Windows itself has great backward compatibility and a lot of developers are using it to create new software thanks to Visual Studio and .NET Windows has cemented itself as a platform with the most available software.

The popularity of Windows as the home operating system and as a gaming platform has made it quite interesting in eyes of various developers and tons of small applications are made daily for it. Windows 11 has also brought native android support to it and that has just expanded its already impressive catalog of applications.

Freedom of choice

Overall Windows PC is most appealing for users that like to be able to choose everything, from hardware components to software they would like to use. No other platform will give you larger freedom of choice and better personalization options.

This post will guide you in fixing high CPU, Memory, and Disk usage problems caused by NTOSKRNL.exe. NTOSKRNL stands for “NT Operating System Kernel. This file is a kernel image that is responsible for a lot of systems-based processes such as Hardware Virtualization, Process, and Memory. Aside from that, it is also the one that compresses the old pages of memory that reduces the overall amount of memory being used. If you notice that your computer is running slowly and you find that the NTOSKRNL.exe file is hogging your resources such as disk usage, CPU usage as well as memory usage, then read on as this post will guide you in fixing the problem caused by NTOSKRNL.exe. Make use of the options given below to resolve the issues caused by NTOSKRNL.exe. 1] Scan your computer for potential malware There might be a good chance that your computer might be infected with malware. And this malware might be associated with the NTOSKRNL.exe file and hence making it consume a lot of system resources. So, I would really recommend you to make sure that your Antivirus is up to date and then scan your computer with it specifically the C:/Windows/System32 folder because this is the location where the NTOSKRNL.exe file is located.

Option 1 – Put your computer in a Clean Boot State

The first thing you have to do is to put your computer in a Clean Boot State as this can help you in finding any incompatible programs that are causing the problem.

• 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.

Once you’ve found any incompatible programs, you need to uninstall them. Refer to the steps below to do so.

• 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 – Update or rollback drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 3 – Try to run the DISM tool

If the first two options didn’t work, then running the Deployment Imaging and Servicing Management might. 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.

Option 4 – Try to stop the Runtime Broker process

The RuntimeBroker.exe or the Runtime Broker process is the one that monitors access to Windows APIs to make sure that the apps do not violate the core security of Windows. This process usually leaves a very small footprint. However, there are times when it consumes more resources than it’s supposed to and does not release memory after the work is done that results in a memory leak. As a result, it affects NTOSKRNL.exe which is why you have to stop the Runtime Broker process. To do so, refer to these steps:

• Tap the Ctrl + Shift + Esc to open the Task Manager.
• After opening Task Manager, go to the Processes tab and look for the Runtime Broker process.
• Once you find it, check if it is using more than 15% of your memory. If it is, then you most likely have an issue with an app installed on your computer.
• Select the Runtime Broker process and right-click on it and then click on the End Task option to end its process.

Option 5 – Try to run the Performance Troubleshooter

• Tap the Win + R keys to open the Run dialog box.
• Type “msdt.exe /id PerformanceDiagnostic” in the field and hit Enter to open the Performance troubleshooter.
• Then click on Next to get started. Wait until the process is completed.

Option 6 – Try using the Windows Performance Toolkit

You can also use the Windows Performance Toolkit in finding the root cause of the problem. Just refer to the following steps to use this toolkit.

• Search for “cmd” in the Cortana Search box and click on Command Prompt from the search results to open it.
• Next, type in the command given below or copy and paste it and then hit Enter:

xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 256 -FileMode Circular && timeout -1 && xperf -d cpuusage.etl

• After executing the command, wait for at least 60 seconds and then check the logs of the Windows Performance toolkit which is stored in a file named cpuusage.etl in the folder located at C:/Windows/System32. From there, you should see a list of all the causes of the System Resources being hogged.
