Happy New Year from ErrorTools.com!!!

If you are trying to copy or move files to and from your external storage device but you suddenly encounter the error 0x800703EE, then you’ve come to the right place as this post will guide you on how you can fix this error in your Windows 10 computer. This kind of error when copying files may be accompanied by an error message that says, “The volume for a file has been externally altered so that the opened file is no longer valid”. This error prevents you from copying or moving the files to and from the external storage device. This kind of issue might be caused by a service that belongs to a backup program that could be blocking the operation or a conflict with your third-party antivirus program. In addition, the error could also be due to corrupted or outdated USB drivers or it could be caused by a disabled Windows Backup and Volume Shadow copy service. It is also possible that some system files are corrupted or that the drivers for the external device are also corrupted. Whatever the cause is, here are some options you need to check out to fix the error. Before you troubleshoot the error, you might want to try moving the files to another location on your local drive and remove the USB drive and insert it back again. After that, try to move or copy the file to the USB drive and see if it still throws an error. If it does, then you need to troubleshoot the problem further by following each one of the suggestions given below.

Option 1 – Update or reinstall the Universal Serial Bus Controller driver

Since it could be a driver issue, you can try to update or reinstall the Universal Serial Bus Controller drivers using the Device Manager. Refer to the following steps:

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.

Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.

• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 2 – Try checking the Volume Shadow Copy and Windows Backup services

The next thing you can do to fix error 0x800703EE is to check the Volume Shadow Copy and Windows Backup service.

• First, tap the Win + R keys to open the Run dialog box and type “services.msc” in the field, and hit Enter to open the Services Manager.
• From there, look for the Volume Shadow Copy service and right-click on it, and then select Properties.
• After that, make sure that its Startup type is set to Manual and that its status is “Started” so if it isn’t, you need to click on the Start button and then on the Apply and OK buttons to save the changes made.
• Once done, look for the Windows Backup Service and repeat the same process you did with the Volume Shadow Copy service.
• After you complete the steps, restart your computer and see if the error is now fixed.

Option 3 – Restart your computer in a Clean Boot State

If a third party program like antivirus is the one that’s causing the problem, you can try to put your computer in a Clean Boot State to isolate the issue by following these steps:

• 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.)
• Now try to copy the files to your external storage device again and check if the error is now gone.

Option 4 – Try to run System File Checker or SFC scan

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow and hit Enter.
• Once done, restart your computer.

Option 5 – Try to delete the Filter drivers

Note that this option is only applicable if you see the error 0x800703EE accompanied with the “The volume for a file has been externally altered so that the opened file is no longer valid” error message. Before you start, create a System Restore Point first.

• Open the Registry Editor and navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E965-E325-11CE-BFC1-08002BE10318}
• After that, select the “{4D36E965-E325-11CE-BFC1-08002BE10318}” key and check if you can find the “Upperfilters” and “Lowerfilters” value in the right pane. If you can find them, right-click on them and select Delete.
• Once done, exit the Registry Editor and restart your computer.

If you are trying to open a program or a game but you suddenly see a dialog box with a message stating that the application was unable to start correctly along with the Error Code 0xC000007B , STATUS INVALID IMAGE FORMAT then this indicates that the application is not compatible with the architecture of your Windows 10 computer or is missing dependencies. Although error code 0xC000007B can also occur with other various programs, the STATUS_INVALID_IMAGE_FORMAT error code also means that when you try to run an application that’s designed to run on a 64-bit system and hence gets into a termination state. In addition, if you are also pointed to the NTStatus.h file then it means that the error might be caused by some file corruption. Here’s the full context of the error message:

“0xC000007B | STATUS_INVALID_IMAGE_FORMAT | {Bad Image} %hs is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.”

When you see this error message, the first thing you can do is to click on OK to close the application and then try installing the media again to see if it fixes the issue. If not, then you can check out the suggestions given below.

Option 1 – Try installing the application with admin privileges

The first thing you can do to fix the error is to restart your Windows 10 computer and then try installing the application again and this time with admin privileges. Just right-click on the application and select the “Run as Administrator” option. And if your account is a regular one, you need to make sure to ask an admin to help you in installing the application by entering the password when you are prompted to do so.

Option 2 – Install and update Dependencies

There are times when programs and applications need to have drivers and supporting software installed for them to properly work. Although the installation usually takes care of it, it’s time for you to do some manual checks especially if you are getting this issue of abnormal program termination.

1. Install some qualified drivers

A number of high-end games and applications need to have correct and valid drivers for them to work. They just don’t work with general drivers though. Microsoft has this Windows Hardware Quality Labs testing also known as WHQL testing which makes sure that drivers meet the correct experience and pass through the proper testing before certification. Thus, when installing drivers, you need to ensure that they are qualified drivers for your Windows 10 PC.

2. Download and install or update DirectX

As you know, Microsoft DirectX is a suite of technologies developed by Microsoft to provide hardware acceleration for heavy multimedia applications like HD videos and 3D games. Since you are using Windows 10, you have the DirectX 12 version while the earlier Windows versions use the DirectX 11 version.

3. Install the Microsoft DirectX End-user runtime

The Microsoft DirectX end-user runtime gives updates to version 9.0c as well as previous versions of DirectX. To install it, click on this link and download it.

4. Update or install the .NET framework

The .NET framework is used by games and applications during development which means that without the runtime files that are installed in your computer, it definitely won’t work. Thus, you need to install or update this framework. You can also use the .NET setup verification tool to verify it.

Option 3 – Try running the System File Checker Scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Error Code 0xC000007B , STATUS INVALID IMAGE FORMAT error. 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 with good system files. 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.

Computer viruses are malicious applications that have the ability to self replicate and spread over the system and various devices, just like viruses in organisms. We all know that computer viruses are bad and that you should avoid them however you can. So in this spirit, we are taking a deeper dive into what kind of viruses exist and how they function.

1. File-infecting Virus

A virus that attached itself to an executable program. It is also called a parasitic virus which typically infects files with .exe or .com extensions. Some file infectors can overwrite host files and others can damage your hard drive’s formatting.

2. Macro Virus

This type of virus is commonly found in programs such as Microsoft Word or Excel. These viruses are usually stored as part of a document and can spread when the files are transmitted to other computers, often through email attachments.

3. Browser Hijacker

This virus targets and alters your browser setting. It is often called a browser redirect virus because it redirects your browser to other malicious websites that you don’t have any intention of visiting. This virus can pose other threats such as changing the default home page of your browser.

4. Web Scripting Virus

A very sneaky virus that targets popular websites. What this virus does is overwrite code on a website and insert links that can install malicious software on your device. Web scripting viruses can steal your cookies and use the information to post on your behalf on the infected website.

5. Boot Sector Virus

These viruses are once common back when computers are booted from floppy disks. Today, these viruses are found distributed in forms of physical media such as external hard drives or USB. If the computer is infected with a boot sector virus, it automatically loads into the memory enabling control of your computer.

6. Polymorphic Virus

This virus has the capability to evade anti-virus programs since it can change codes every time an infected file is performed.

7. Resident Virus

A resident virus stores itself on your computer’s memory which allows it to infect files on your computer. This virus can interfere with your operating system leading to file and program corruption.

8. Multipartite Virus

A type of virus that is very infectious and can easily spread on your computer system. It can infect multiple parts of a system including memory, files, and boot sector which makes it difficult to contain.

Changing Taskbar location in your Windows 10 is an easy task but lately, Microsoft has removed the option to just drag it to one side of the screen and place it there, now in order to change location we need to do a little more work but do not worry it is not difficult at all. Right-click on the taskbar to open its properties menu in the menu, on the bottom choose taskbar settings. Once the settings dialog opens, on the right side locate the taskbar location on screen. Click on the dropdown menu and choose the desired location for the taskbar.

Instaling and removing applications from your Windows can sometimes leave some traces that are unpleasant and can cause annoyances. One of these annoyances is the program in the startup section of the task manager.

If you ever opened task manager and went into the startup section trying to disable some of the startup items on your Windows boot there might be a chance that you have experienced and seen a program without any icon or information about it just sitting there.

This is due to some applications being removed from the system but for some reason, it still shows itself in startup and it is quite annoying. So here we will show you how to get rid of this annoyance so your startup is clean again without junk in it.

Removing a program from startup

Locating the source of the issue

The first thing of course is to open the task manager itself and navigate to the startup tab. Inside the startup tab right-click on the column header and tick or enable Startup type and command line. Now you will see the location of the supposed file (that is missing or you could just go there by right-clicking on the item, but here it is greyed).

99% of the time startup type will be registry since the file is missing, if it was a file fix would be just to simply delete the file in the folder but since it was installed and not properly removed registry key is still present but the file cannot be found. After confirmation that the file is indeed missing and that the startup type is registry open the registry editor by typing Regedit in search and pressing enter.

Removing the key from registry

Inside Registry editor navigate to: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. Inside on right part, you will see all auto-start entries added by installed applications.

Locate one that is causing issues by comparing its path with the path inside the task manager command line and delete the key. Once the key is deleted right-click on RUN on the left part and choose HKEY_LOCAL_MACHINE to quickly jump on that key location and repeat the process of key deletion if needed. HKEY_LOCAL_MACHINE will delete startup entry for all users and sometimes entry will not be present here since the application is not installed for all users or there are no other users on the machine.

After the procedure is finished, reboot your systems in order to apply changes.

DLL files, also known as Dynamic Link Libraries are external parts of applications that run on Windows as well as other operating systems. Almost all applications are not complete in themselves and store code in different files. In this post, we will be discussing one DLL file called ntdll.dll. It is described as “NT Layer DLL” which means that it contains some Kernel functions that help in the normal functioning of the Windows operating system. It is created by Windows in the System32 folder when the OS gets installed. This file can serve different programs simultaneously by providing them with different Kernel functions which support the programs’ performance. However, if you encounter the ntdll.dll file error on your Windows 10 computer, read on as this post will guide you in fixing the problem.

Option 1 – Try to re-register the ntdll.dll file

You may have to re-register the ntdll.dll file using the regsvr32.exe before you can successfully install the program and fix ntdll.dll file crash error. The Regsvr32 tool is a command-line utility that can be used to register and un-register the OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
  • exe /u ntdll.dll
  • exe ntdll.dll
• You should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 2 – Disable problematic Internet Explorer add-ons

There are instances when some add-ons in the Internet Explorer browser can cause the ntdll.dll file crash error. Thus, you need to disable some add-ons in Internet Explorer and then check if it fixes the problem.

Option 3 – Try running the DISM tool

You might want to repair potentially corrupted files in your system as having them could also trigger the ntdll.dll file crash error. To repair these corrupted system files, you can run the DISM commands:

• Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
• After that, input each one of the commands listed below sequentially to execute them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism /Online /Cleanup-Image /RestoreHealth

• Once you’ve executed the commands given above, restart your computer and check if the DCOM error is now fixed.

Option 4 – Try to run the Program Compatibility Troubleshooter

You might also want to run the Program Compatibility Troubleshooter. This built-in troubleshooter is available in the Windows Update & Security section. From there, select Troubleshoot. This will find a list of programs for you and since you have already downloaded the driver files, just click on Not Listed located at the top of the program list. After that, browse and select the driver files and then let the program do its job.

Option 5 – Try to replace the DLL file with a trusted source

• First, you need to get the new DLL file from another computer with preferably the same file version number.
• After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
  • x86: This PC > C:WindowsSystem32
  • x64: This PC > C:WindowsSysWOW64
• Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
• Now type the “regsvr32 ntdll.dll” command and hit Enter.
• Restart your PC and check if the error is now fixed.

Option 6 – Try scanning your computer using Windows Defender

The ntdll.dll file crash error might also be infected with malware or virus and to eliminate it, you have to scan your computer using security programs like Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.
• Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.

Bluetooth troubleshooting, I believe firmly that each one of us who has Bluetooth sooner or later had some issues with it, after all, it seems that it is in nature of radio transmitters to from time to time due to nature of signal and nature of Windows loose communication between them and can cause device which seems to work properly but can not establish the connection. Most of the time Bluetooth issues are like that, the signal gets lost, the connection is broken, and establishing it again can be sometimes real pain, luckily for you, we have experience in this field and are here to help you and provide you with tips how to solve Bluetooth connection issues based on our own struggles.

1. Check if BlueTooth is ON

   Yes, this seems stupid and sounds a lot like is it plugged in but here me out. Due to lost connections and different power plans setting inside your Windows, your Bluetooth receiver might be actually turned OFF thus preventing your other device to find your computer. Checking to see if Bluetooth has been by some accident turned OFF and switching it back ON should be the first thing to do and this could be a simple solution for your problem.

2. Restart the BlueTooth device.

   Yup, another of these have you tried turning it OFF and turn it back ON advice which seems like tech cliche but in the case of Bluetooth, this can actually solve your problem. Radio signals and radio connections are not the same kinds of beasts like cable ones and sometimes Bluetooth device remembers certain information and can cause conflict. Turning it OFF and then back ON will clear its memory and cache and you will be ready for a new start hopefully solving your issue along the way.

3. Check power supply

   If your Bluetooth device does not have a battery indicator, it would be wise to check on the battery status of the device. Sometimes we forget to charge batteries, sometimes someones have drained them. Checking the battery or just checking if the power supply is working properly should not be overlooked and it definitely should be on your to-do list of quick solutions.

4. Restart PC

   Sometimes most simple solutions work and if restarting your Bluetooth device did not work, maybe restarting your PC will. When you restart the PC, you clear the cache and many other things that could potentially be the reason for connection issues.

5. Checks BlueTooth device distance from computer or interference from obstacles

   The Bluetooth device operates via radio waves, and like wi-fi, if the distance from the computer is too large or you have some thick walls in between signal will degrade and be almost useless. Be aware that your PC might catch device waves and detect them but the signal itself could be too weak for the connection to work properly. Take the device and move it closer to the PC to see if the problem will go away, if it does issue was in distance or walls.

6. Reinstall or update device drivers.

   Sometimes the issue could be in Windows update and old drivers, make sure that all of your drivers are updated with the latest version and that Windows itself has the most recent update in it. Trying to reinstall device cold also solve some the issue.

7. Remove and Pair deice again

   if you tried all previous steps, try removing the device from Windows and then pairing it again. This could solve the issue since Windows itself could have mistakenly saved it like something else and can not recognize it.

8. Use Windows troubleshooter

   If everything else failed, right-click and go to troubleshoot. Windows troubleshooter will try to find the issue and direct you to a solution.

If sadly none of these things do work, you should contact the device manufacturer since it is a very good chance that the problem is one of a hardware nature.

Have you been feeling anxious in the digital space? Feeling like you have a million eyes on you each time you visit a website? It can definitely make you uneasy. Luckily there’s an easy fix, and it’s called a VPN.

In this article we’ll take you through the basics of what a VPN does and some of the biggest benefits you can reap from buying one.

VPN: definition and how it works

VPN stands for Virtual Private Network, so its name already says a lot about what it does. 

A VPN is specialized software that keeps your browsing private and secure. Essentially it hides your identity, preventing possible cyberattacks and data theft. This is especially important in cases of public network use, where you’re highly exposed to potential threats.

To be more specific, this software encrypts your Internet Protocol (IP) address by filtering it through a server hosted by the VPN provider first. That way, it prevents your Internet service provider, third parties and lurking online thieves from tracking the actual you.

Some providers, such as Surfshark VPN with its IP Rotator feature, even make it a habit to frequently change your IP address to further protect your identity. With most VPN providers, you can also appear to be in a completely different country, adding to your disguise.

There are tons of advantages you can look forward to if you decide to use a VPN. Take a look at some of the crucial ones.

Benefits of using a VPN

When choosing a VPN, you can find both free and paid options. We recommend you go with the paid ones, since they have stronger security, encryption and data protection, as well as more advanced features. Free VPNs come with limitations and risk of malicious attacks on the software itself.

You can choose to buy a singular VPN service or opt for antivirus software that has a VPN built in, for example Bitdefender’s Ultimate Security plan. That depends on what you use your computer for and how much. 

When you pick one, here’s what it can do for you.

1. Access region-specific content

When we said you could change your location, we meant it. Say you’re using a streaming service and a show you desperately want to watch isn’t available in your country. You can use your VPN to make it look like you’re browsing from a country where it’s unlocked.

This option is also convenient for gamers who want to access maps, skins and other in-game items unavailable in their location.

In addition, you can use this powerful feature when you’re traveling to a region where some of your favorite content may not be accessible.

Do keep in mind that you need to read the Terms and Conditions (yeah, we know - who does that?) of your games and services before doing this, since you could end up getting a penalty. It’s also important to remember that there are entire countries that have strict regulations or even bans on VPNs, for example Belarus, Russia and China. So make sure to be very cautious with your VPN use, friends.

2. Browse like no one’s watching

VPNs shield your browsing habits from prying eyes on the web. Those can be malicious hackers or just third-party cookies tracking your every move to later bombard you with targeted ads. For example, Surfshark VPN features a Cookie blocker that blocks all cookie-related pop-ups and lets you browse in peace (and secret). It works even when the VPN is turned off, which is also pretty neat.

In addition, their CleanWeb 2.0 technology makes sure ads and especially malware don’t stand a chance at all, since they’re blocked before they can even load.

The inability of sites to track your browsing means they can’t collect and analyze any of your data. So, your personal information - or your company’s information in case that’s what you’re using your computer for - is entirely hidden and secure.

3. Save money

It’s well-known that the prices of certain items and services vary based on your location, browsing time, age and many other factors. This most commonly goes for airline tickets and hotel stays.

You can use your VPN to avoid high prices and surcharges. Clear all cookies, turn on your VPN and visit an online shopping site to check out their prices. Then compare your findings with the offers you see when your VPN is off, when you spend a long time on the site or have an active account with the company. 

Sometimes this can really help you find the best deals and avoid breaking the bank. But again, check the Terms and Conditions before you purchase something using a VPN.

4. Secure your smart home

The more smart devices you have connected to your network, the more exposed you are to potential cyberattacks. Phones and computers are generally designed to be decently secure even without a VPN or antivirus, but smart home devices leave a lot to be desired in that regard. 

Protecting your home network with a VPN software means all devices connected to it are secure, be it an air purifier or Alexa.

5. Prevent connection slowdown

Your ISP can intentionally slow down your internet speed based on how much data you’ve consumed (data throttling) or your activities online (bandwidth throttling).

But with a VPN, what kind of data you send and receive and how much is entirely hidden. Therefore, if your ISP can’t see you, they can’t control you and they can’t throttle down your speed.   

The bottom line

You can never be too safe online. So definitely think about getting yourself a solid VPN to pump up your privacy and security as much as you can. And if you have any questions or need help choosing the perfect software for you, feel free to reach out to us.

As you already know, the Windows Sandbox is one of the new features in Windows 10. However, just like other new features, it also throws up errors and one of them is the error that states,

“Windows Sandbox failed to start, Error 0x80070057, The parameter is incorrect”.

This particular error in Windows Sandbox occurs due to its dependence on numerous components of Windows 10 that are related to Hyper-V and Virtualization mainly. To fix this error, there are several options you can check out. You can try to install any pending updates on your Windows 10 computer, as well as make sure that all the services related to Windows Sandbox are enabled.

Option 1 – Try to run the Windows Updates to install pending updates

The first thing you can do to resolve the “Windows Sandbox failed to start, Error 0x80070057” is to check Windows Updates in your computer and see if there are any pending Windows Updates you have to install. All you have to do is go to the Windows 10 Settings app and then go to the Windows Updates section and click on the “Check for updates” button to check if there are any pending updates that are needed to be installed. This could fix the Windows Sandbox error.

Option 2 – Ensure that all the supporting processes and services are running properly

If running Windows Sandbox as an administrator didn’t fix the error, you have to ensure that all related processes for Windows Sandbox are running properly. To do that, follow these steps:

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
• Next, from the list of services, look for the following services in the given order:
  • Network Virtualization Service
  • Virtual Disk
  • Hyper – V Virtual Machine
  • Hyper – V Host Computer Service
  • Container Manager Services
• After you find the aforementioned services, make sure to check if they are enabled or not and then restart each one of them.
• Once done, try to open the Windows Sandbox again and see if the error is fixed or not.
