Hello everyone and welcome to another tutorial on errortools.com, Windows itself when it is installed has a general idea about certain file types and how to open them, for example, image files would be opened with application photos, web links with the edge, etc. So when we double click on the known file type, Windows will start the default application for that type and open the file in it. But what if we do not want to open files in applications Microsoft thinks we should? What if we want to open the website in firefox or images in photoshop, or whatever. Luckily we can easily change which application Windows uses for which file type. Click on ⊞ WINDOWS to open the start menu and choose settings. On the settings screen, choose Apps. When the Apps screen opens on the left click on Default apps. On right, you will get a list of Windows default applications for certain types of files. Click on any application you would like to change and choose from the drop-down list a new one. Click on it and you are done.

‘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.

If you have suddenly run into a problem when trying to connect or pair your Bluetooth keyboard with your Windows 10 computer, read on as this post will guide you on how exactly you can resolve the problem. This kind of problem typically occurs when you’ve disabled the Bluetooth option. However, this option is already enabled and you still encountered the same error message saying, “Check the PIN and try connecting again”, then you need to troubleshoot the problem further. In most cases, this kind of issue can be fixed when you restart your computer and go to the Windows Settings and select the “Add Bluetooth or other devices” option and then put the keyboard into pairing mode. And when the keyboard appears in the “Add a device” dialog box, just select it. On the other hand, if your Bluetooth keyboard won’t get connected to your Windows 10 computer and you encounter an error that says, “Can’t pair Bluetooth keyboard, Check the PIN and try connecting again”, then you need to check out the options provided below but before you do so, make sure that you create a System Restore point first as some of the troubleshooting options provided involves the Windows Registry.

Option 1 – Try to use the Device Pairing Wizard

The Device Pairing Wizard is the one that allows your computer to look for any new devices and display them underneath it. All you have to do to use this wizard is to follow its instructions to connect your Bluetooth device to Windows 10. To get started, follow these steps:

The newest piece of hardware for PC or console users is not really what anyone has expected and for sure not from a company like Cooler Master. I going to admit right here that I am a big fan of Cooler Master PC cases, I like them and they are always one of the things that I consider when building a new PC, overall I like their ideas and quality so personal for me it was quite a surprise to see that they are one that is making a new generation gaming chair. Now truth to be told Orb X is not your typical gaming chair as you can clearly see from the pictures. The chair itself will come in two colors: white or black and RGB lighting looks to be prominently featured throughout. The chair itself is advertised as both meant and aimed for professional and gaming crowds but I believe the gaming crowd is in general more interested in this hardware piece. Hardware is enclosed in a fully motorized shuttle dome which aims to maximize your privacy, it supports a single 49inch display or three 27inch monitors along with surround speakers if you do not wish to use headphones. It offers an adjustable headrest, lumbar support, and footrest so you can spend some time in it and be comfortable. Controls on the chair itself allow you to raise or lower the dome for easier getting in and out of it. Orb X also has a compartment in its backside, it folds out and has a sliding tray designed to hold your PC or console. Everything is enclosed so wiring is not the issue. Overall Orb X seems really like the computer chair of the future, Cooler Master expects to release the Orb X by December 2021, priced around $12,000-$14,000.

Solution

Further Information and Manual Repair

Users have found several manual repairs that have fixed the problem without needing to contact technicians for extra help. While the methods below should solve your problem easily, if this is the first time you have encountered the issue you may want to do a simple restart. This has fixed the problem for some users and is the easiest first troubleshooting move. If it doesn’t work move on to the methods listed below, which are easily completed without extra help.

Before trying any of these methods, please make sure that you are logged into a profile that is listed as the administrator of the computer of his administrative powers enabled. If this is not the case you will not be able to complete the following methods. Please log out and log back in on the administrator profile.

Method 1:

First, check to see if you have a third-party anti-virus program installed on your computer. Some users believe that the built-in Windows Defender program is not powerful enough to handle the safety of their computer so they usually download a third-party program. However, that program may have caused a conflict with Windows Defender and may not allow it to open. If you do have a third-party program installed, try uninstalling it then manually starting Windows Defender.

Method 2:

If method one does not work, you may be infected by malware or a virus that has tampered with the settings on your computer and will not allow Windows Defender to start automatically or manually.

First, open Run by holding the “Win” key and pressing the “R” key. Then type “Regedit”. The program will ask for permission to follow through with this action. Click on “Yes” and the Open Registry Editor will open.

Find the HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersionImage File Execution Option and check to see if there are any files similar to MSASCui.exe or MpCmdRun.exe. If there are any file entries that resemble that, you will want to right-click on them before selecting the “Delete” option. If you do not see any entries that match, this is not the issue with your Windows Defender and you will want to try another method.

The Registry on your computer is very important. It helps tell your computer what programs are safe to run, what programs should be run, and what programs should not be run. If it is tampered with by a virus or Malware, multiple system operations can be affected.

However, if you did find similar file names, and you deleted them, try to start Windows Defender manually. If it does not work again, move on to the next method. 

Method 3:

If the first two methods do not work for your issue, and you are still receiving error code 0x80073afc when attempting to start Windows Defender, this step should solve the problem if you have Restore Point installed on your computer, which you most likely do.

For this method, we will be restoring your computer to a previous Restore Point. First, just like in method two, hold the “Win” key and press the “R” key. This will open run. Next type “Rstrui.exe” and click “ok”. After some time, you will see System Restore Windows. Click “Next” and select the restore point that you would like to go back to. After your computer has restored to the point you selected, check to ensure that Windows Defender has started correctly.

If the above methods aren't able to rectify the issue, you might have to download and install a powerful automated tool to get the job done.
