How to Fix ntdll.dll crash Error on Windows

NDIS or Network Driver Interface Specification is a programming interface for the network interface cards that aids in the proper functioning of a system driver in a computer network. The NDIS helps the computer system in order to communicate with other connected devices and hardware components on a computer network. In relation, the ndis.sys file is a critical system file developed by Microsoft for the Windows operating system. As you know, sys files or system files are important parts of the Windows operating system as well as a repository of system driver settings used by Windows to communicate with the connected hardware and devices. The ndis.sys files are stored mostly in a driver folder at C:/Windows/System32/drivers and as mentioned, these files are essential for the system to function properly. Although the presence of ndis.sys system file is not yet known to affect the normal functioning of the Windows OS, some of the Windows 10 users reported that they encountered ndis.sys blue screen errors on their PCs. Blue Screen of Death errors or Stop errors usually occurs when you open a program or a function. Moreover, it could also occur when the driver gets loaded during the system startup or during system shutdown. It isn’t yet clear what really causes the ndis.sys blue screen error. However, like other Stop errors, it may occur due to corrupted files, misconfigured device drivers, bad drivers, corrupted Windows Registry, missing or damaged system files, and malicious programs. Aside from the aforementioned reasons, the ndis.sys blue screen error might also occur if your hard disk is damaged and if the RAM is corrupted. In such cases, a lot of users usually disable the ndis.sys file. However, it won’t really resolve the issue since the file is required for the normal functioning of the operating system and even when you disable the file, it’s pretty useless as the file will start all over again. In addition, you might want to disable security programs or firewalls and antivirus programs in the meantime to check if these programs are the ones that are causing the error. And if you’ve determined that none of the security programs or firewalls and antivirus programs are to blame, refer to the options below that might help you resolve the DRIVER_IRQL_NOT_LESS_OR_EQUAL or ndis.sys Blue Screen of Death error.

Option 1 – Try to update or reinstall the PC device driver

The Ndis.sys Blue screen error can occur when the device driver in your computer is outdated or corrupted. Thus, you either have to update or reinstall it to fix the issue.

• 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. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC.

Option 2 – Rollback your Network drivers

If you have updated the driver software as of late and you suddenly got this BSOD error, you might have to roll back the device driver – in other words, switch back to the previous working version. To do that, follow these steps:

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
• Next, select the driver entries that are labeled appropriately other than anything in the context of the WAN Miniport.
• Then select each one of them and double-click to open a new mini window.
• After that, make sure that you’re on the Driver tab and if you are not, just navigate to it then click the Roll Back Driver button to switch back to the previous version of your Network adapters.
• Now restart your computer to successfully apply the changes made.

Option 3 – Try running the System File Checker

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the ndis.sys Blue Screen of Death 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 and hit Enter.

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 – Try running the CHKDSK utility

Running the CHKDSK utility might also help you resolve the Netwtw04.sys failed BSOD error. 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 following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

Option 5 – Run the DISM Tool

The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:

• Open the Command Prompt as admin.
• Then type in this command: DISM /Online /Cleanup-Image /RestoreHealth
• The DISM command you entered will repair the corrupted system image. Do not close the window if the process takes a while as it will probably take a few minutes to finish.
• Restart your PC.

Option 6 – Perform a System Restore

Performing a System Restore on your computer can also help you fix the ndis.sys Blue Screen of Death 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.

One of the most common ways cybercriminals use to inject suspicious code into devices is by tricking users into installing a malicious program on a targeted device. Oblivious users are vulnerable to such tricks, which is why Microsoft has been working hard in the background to address this issue. Recently, Microsoft announced the availability of a sandboxed version of Windows 10 that runs inside Windows 10 in order to isolate suspected software to run inside it and protect the system from potential threats. This Windows Sandbox feature is a new feature that keeps your computer secure. It is a virtual disposable environment that you can enable. So if suspect any software of being malicious, you can run this software in an environment and ensure that it won’t interfere with any normal processes and would not jeopardize files on your computer. To simply put it, “Windows Sandbox is a new lightweight desktop environment tailored for safely running applications in isolation”. So if the Sandbox is closed, all the residual files, software, and other data are deleted permanently. To enable Windows Sandbox, refer to the instructions provided below. Step 1: You have to make sure that you are running either Windows 10 Enterprise Editions or Windows 10 Pro and that your computer is running build 18305 or newer. Step 2: After that, you have to enable Virtualization to let another instance of Windows 10 running in Sandbox mode. Step 3: Next, search for Windows Features on and off in the search box and then select the appropriate entry. Step 4: From the list, go to the mini window and check the Windows Sandbox and then click on OK. Step 5: Afterwards, in the Cortana Search box, search for “Windows Sandbox” and select the related entry to run it in an elevated window. Step 6: Then from your main computer (host), copy the executable file and paste it inside the Windows Sandbox environment. Step 7: Now run the executable file in the Sandbox environment and use it as you normally do. Step 8: Once you’re done, close the Windows Sandbox application and as mentioned, every data regarding the executable file and the temporary environment will be deleted. Step 9: And for the sake of safety, ensure that there are no modifications made to the host because of the executions in the Sandbox environment. You have the option to contact Microsoft for feedback related to Windows Sandbox. You can use the traditional Feedback Hub if you have any suggestions or any issues. Just fill in the appropriate details and select Windows Sandbox for the feature category under the Security and Privacy section. And if you have any issues related to the execution of and within Windows Sandbox, simply choose “Recreate my problem” then select Start capture to reproduce the issue, and once you’re done, select Stop capture.

If you got the Microsoft Store error code 0x80072F30 while trying to open Microsoft Store, then it indicates that the Store fails to connect to the internet or is not able to launch successfully for some reason. It could be that the Windows Update Service has stopped or the Windows Store cache might be corrupted or it could just be due to a poor internet connection. Whichever the cause is, you have to fix this error so that you can use Microsoft Store again and you won’t be getting the following error message every time you open the app:

“Check your connection, Microsoft Store needs to be online, It looks like you are not, error code 0x80072f30.”

The error code 0x80072F30 is related to the Windows Store which prevents it from opening properly. To resolve this problem, you can try fixing the problem with the help of the options given below. Follow each one of them carefully.

Option 1 – Check your internet connection

The first and most obvious thing you can do is to check your internet connection. This may only be a basic tip but it sure works like a charm in most cases. And if you have another internet connection available, you can also try connecting to that and see if you can pull up Microsoft Store or not. 1] Change your internet connection: A basic tip, but sometimes works like a charm. You may want to check if your internet connection has an issue, or you can also try opening a website and see if you can open it and if possible try connecting to a different internet connection and see if the Microsoft Store opens for you. We also suggest you try changing your DNS and see if it helps.

Option 2 – Check the date and time as well as the time zone of your PC

A lot of services and apps rely on the Date, Time, and Time Zone of your PC which is why if they are not configured correctly, a request from the client machine will be rejected from the server and the same thing happens with the Microsoft Store.

• First, go to Settings > Time and Language.
• From there, check if it is set to Automatic or not – if it is, switch the toggle button off to set the Time and Time zone manually.
• Then select the right time zone manually.
• On the other hand, if the Time and Time zone is set manually, you have to switch the toggle button on to set Time and Time zone automatically.
• Restart your PC and afterward try opening Microsoft Store again and check if the problem’s fixed or not.

Option 3 – Run the Network Adapter Troubleshooter

Since Windows 10 is packed with various troubleshooters – one of which is the Network Adapter Troubleshooter – you can use it to troubleshoot the problem. To use it, follow these steps:

• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Option 4 – Try to reset the Microsoft Store cache

Just like browsers, Microsoft Store also caches as you view apps and games so it is most likely that the cache is no longer valid and must be removed. To do so, follow the steps below.

• Right-click on the start button and click on Command Prompt (administrator).
• Next, type in the command, “exe” and tap Enter. Once you do, the command will clear the cache for the Windows Store app.
• Now restart your PC and afterward, try opening Microsoft Store again.

Option 5 – Check the Windows Update Service status

You might also want to check the status of the Windows Update Service since the proper functioning of this app depends on the Windows Update Service. It could be that there is some issue with the service which is why you’re getting the error code 0x80072F30 while trying to open Microsoft Store.

• Tap the Win + R keys to open the Run dialog box.
• Then type “services.msc” in the field and hit Enter to open Services.
• Next, look for Windows Update Service from the list of available services in Windows.
• Once you see it, check if its status is STOP or Pause and then change the status to Automatic.

High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text, audio, and video. A HEIF image using High-Efficiency Video Coding, HEVC, requires only about half the storage space as the equivalent quality JPEG. HEIF also supports animation and is capable of storing more information than an animated GIF or APNG at a small fraction of the size. HEIF files are a special case of the ISO Base Media File Format (ISOBMFF, ISO/IEC 14496-12), first defined in 2001 as a shared part of MP4 and JPEG 2000. Introduced in 2015, it was developed by the Moving Picture Experts Group (MPEG) and is defined as Part 12 within the MPEG-H media suite (ISO/IEC 23008-12). HEIF was adopted by Apple in 2017 with the introduction of iOS 11, and support on other platforms is growing.

HEIF files can store the following types of data:

Image items

Storage of individual images, image properties, and thumbnails.

Image derivations

Derived images enable non-destructive image editing and are created on the fly by the rendering software using editing instructions stored separately in the HEIF file. These instructions (rectangular cropping, rotation by one, two or three quarter-turns, timed graphic overlays, etc.) and images are stored separately in the HEIF file, and describe specific transformations to be applied to the input images. The storage overhead of derived images is small.

Image sequences

Storage of multiple time-related and/or temporally predicted images (like a burst-photo shot or cinemagraph animation), their properties, and thumbnails. Different prediction options can be used in order to exploit the temporal and spatial similarities between the images. Hence, file sizes can be drastically reduced when many images are stored in the same HEIF file.

Auxiliary image items

Storage of image data, such as an alpha plane or a depth map, which complements another image item. These data are not displayed as such but used in various forms to complement another image item.

Image metadata

Storage of EXIF, XMP and similar metadata which accompany the images stored in the HEIF file.

All malware is detrimental and the magnitude of the damage will vary greatly depending on the type of infection. Some malware variants modify internet browser settings by adding a proxy server or modify the PC's DNS settings. When this happens, you'll be unable to visit certain or all the sites, and therefore not able to download or install the required security software to clear out the computer malware.
