Fix LoadLibrary failed with error 1114

Default applications in previous Windows versions were a pretty straightforward process. The user went to the settings application and picked for each category which application he would like to choose from the list of installed ones. In Windows 11 things are little changed. In this article, we will show you how to choose the default internet browser inside Windows 11, and sadly it is a more tedious task than in previous versions.

Choosing default browser in settings

As in previous versions of the Windows operating system you will need to use the settings application in order to change your default Internet browser. Previously, in Windows 10, a variety of general categories like email, web browser, and photo viewer were all listed under the Default Apps section of the Settings panel. It was easy to click on one of those categories and click on the option you like best from the small pop-up suggestion window. In the Windows 11 Insider Build, you’ll see a gauche list of an individual file or link types that you’ll need to specify your preferred browser for. The types include: HTM, HTML, PDF, SHTML, SVG, WEBP, SHT, FTP, HTTP, and HTTPS. There are additional optional types you can specify your preferred browser for as well. The issue here is in order to use a single browser which most users do you will have to go through each file type and set your preferred one. I am really not sure why this was introduced or why it has to be this way, all I can do is hope that in the final release of Windows 11 this feature will be rolled back as it used to be and that you could set your default browser in just one simple click.

The Event Viewer in the Windows operating system is used to troubleshoot any computer issues. It is one of the most useful tools that keep logs of both security and system events. It also monitors for both software and hardware problems in the computer. This tool is the only one with amazing features that maintain logs about everything that’s going on in the computer system. It keeps track of all the information to the point where going over them will take a lot of time. Luckily, the Event Viewer tool now allows users to create custom views where you can set the filters and sort the data recorded to limit the information details to only what you’re interested in seeing. For instance, if you want to troubleshoot with one hard drive, you can just create a special custom view to display only the hard drive warnings in the security logs. This will save you hassle and time. Take note that the logs in the Event Viewer are divided into two main categories namely the Window logs and the Application and Services logs. You can just set the filter to the logs by their event id, specific date, and many other events when you have to troubleshoot some problem in your computer. So if you are trying to troubleshoot a problem in your Windows 10 computer and you’re checking the Event Viewer, read on as this post will guide you in creating custom event views in the Event Viewer. To get started, refer to the instructions given below. Step 1: Go to the Start menu and in the search box, type “event viewer” and then click on Event Viewer from the search results to open it. Step 2: After opening Event Viewer, click on Custom Views located in the left pane of the window. Step 3: Next, click on the Administrative events under the Custom View to create special log views. Step 4: Then on the right side of the window, click on Create Custom View to open the Create Custom View window. Step 5: There is a logged drop-down list under Filter. From there, you have the option to choose an appropriate predefined time or use a custom time range for your Custom log views. Step 6: After that, select an appropriate event level for your custom view. You have fine entry-level options to choose from such as critical event level, error, warning, information and verbose.

• Critical – select this if you want to see the events that require your immediate attention in the custom view.
• Error – select this if you want your Event Viewer to display the events that are less critical but hints at the problems.
• Warning – select this event-level if you want to see the event with the potential problem but may not bound to happen.
• Verbose – select this if you want to see detailed information about all the events.

Step 7: After you’ve selected the event level, you now have to select how you want the events to be filtered. They can either be filtered By the log or By the source.

• By the log – you can select two options called Windows log and, Application and Service logs. The Windows logs allow you to filter the logs created during events like setup, security, applications, and system events. While the Application and Service logs filter the log created by the installed applications in your system.
• By the source – select this if you want your Custom View to search for information in event sources. It allows you to view events in detail for various applications and devices.

Note: You have the option to further customize the event logs with more filters like Event IDs, task category, keywords, User, and Computer. Using these additional filters, you can choose to filter the events in the special views by specifying event id numbers in the Event IDs, entering predefined Windows words in the Keyword, specify the user accounts in the User field, as well as choose the system from the server to maintain logs in the Computer field. Step 8: Once you’re done customizing the log filter, click on OK to apply the changes made. Step 9: After that, a Save Filter should be displayed in the Custom View window. Just enter the Custom View name and select the Event Viewer folder where you want to save the Custom view. The folder name should be Custom View by default. And if you want, you can also create your own folder if you want your custom views to be visible to all the system users. Step 10: Next, check all the Users box located in the lower corner of the window and then click the OK button after you’re done. You should now see the customized filter you just created on the left side of the window. Just click on it to check your filtered events in the center of the Event Viewer window. And for you to save the custom view logs, simply right-click on the Custom views you created and then click on Save All Events in the Custom View As from the drop-down menu. Then put a name on the file and select the appropriate location where you want to save the logs and click on the Save button. Note that the log file is saved with the “.EVTX” file extension and when you double click on it, it will open the file in the Event Viewer.

As you know, a Virtual Private Network or VPN is used to access a particular network from another network which is why it is also referred to as a mini-internet. Moreover, you can use it in two ways. One, you can use it to get you access to a closed server which means that you would not be getting access to the internet. Second, you can also use it to access a set of resources while at the same time get access to the internet. However, what if you want to access your resources at home even when you’re away? And what if you want to use the private server at home or at your office even when you’re away? This is where the callout for a VPN server for yourself comes in. And so in this post, you will be guided in how you can create a public VPN server on your Windows 10 computer. Follow each one of the given steps below to get started. Step 1: Find your IP address. This step is rather simple since all you have to do is open Control Panel > Network and Internet > Network and Sharing Center. From there, click on “Local Area Connection” and then click on Details where you’ll see your IP address next to “Autoconfiguration IPv4 Address”. Step 2: Next, set up port forwarding on your router. In this step, you will have to configure port forwarding in your router so that you would be able to connect to the VPN server through a public network like the internet.

• Log in to the Admin Panel of your router. You have to do this since your router will be the gateway for your access to the network.
• After you’re logged in, look for the “Port Forwarding” or “Applications and Gaming” or “NAT/QoS” menu tab and other similar names.
• Now you need to set the port number to 1723 for connections based on Point to Point Tunneling Protocol.
• Then save the configuration and reboot your router.

Step 3: Set up a VPN server on Windows 10.

• In the Cortana search box, type “ncpa.cpl” and click on the related entry from the search results.
• After that, tap the Alt + F keys to bring down the File Menu and then select New Incoming Connection which will open a mini window where you can allow the user accounts on the particular machine to access the VPN connection.
• On the other hand, you can also click the “Add someone” button so that you can add someone else to the whitelist that can access the connection.
• Now click on Next and you’ll see an option to select how people will connect to the network. Check the checkbox for the “Through the Internet” option.
• After that, you will see a page where you have to configure the network. Just select IPv4 and then click on Properties.
• From there, you will be asked to continue some additional settings like letting users access your Local Area Network or how IP addresses will be allocated to these users. Click on OK to save the changes you’ve made.
• Click on Allow Access after you configure the network. And if you want to, you have the option to print this information for future reference or for the client machine.
• Now click on Close to exit the configuration process.

Step 4: Allow the VPN Connections through the firewall In this step, you will have to allow the VPN connections through the firewall.

• In the Cortana search box, type “Allow an app through Windows Firewall” and click on the related search result to open the intended Windows Firewall settings.
• Next, click on Change Settings.
• Then scroll down to check if Routing and Remote Access is Enabled for both the Public and Private networks and click on OK.

Step 5: Set up a VPN connection on Windows 10 Now all that’s left for you to do is to set up a VPN connection on Windows 10.

• Go to Settings > Network and Internet.
• From the list of options given, click on VPN located on the left pane to see the related settings.
• After that, click on the “+” icon to add a VPN connection.
• Next, select Windows Default under VPN Provider and under the Connection Name, input your VPN’s name, and then enter the IP address you got from the VPN service provider under the Server name or address section.
• Now select PPTP under VPN type since it is the most commonly used protocol for VPNs.

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.

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.

Blue Screen of Death errors or Stop errors are indications that something’s wrong with your computer. So when you encounter one, you must find out what the root cause of the problem is before it gets out of hand. One of the BSOD errors you might encounter on your Windows 10 computer is the “DRIVER IRQL NOT LESS OR EQUAL or SYSTEM THREAD EXCEPTION NOT HANDLED, Netwtw04.sys failed” error. As you know, system files or .sys files are some of the essential parts of the Windows operating system. It is a repository of system driver settings used by the Windows operating system in order to communicate with the connected hardware and devices. They are essential for the normal functioning of the operating system. A lot of Windows 10 users are facing this particular Blue Screen of Death error whenever they open an app or disconnect external devices from the system. The Netwtw04.sys file is a part of the Intel PROSet/Wireless Wi-Fi software. And so when you might encounter two kinds of Stop errors for the Netwtw04.sys driver file such as:

1. “DRIVER_IRQL_NOT_LESS_OR_EQUAL What failed: Netwtw04.sys.” – This kind of error message signifies that a kernel-mode driver tried to access pageable memory at a process IRQL that was too high.
2. “SYSTEM_THREAD_EXCEPTION_NOT_HANDLED What failed: Netwtw04.sys” – This error message indicates that the root cause of the error might be incompatible drivers with the operating system. In general, the root cause of the Netwtw04.sys BSOD error might be due to several reasons such as corrupted files, incorrect device driver configuration, malicious programs, outdated drivers, bad drivers, corrupted Windows Registry as well as some damaged or corrupted system files.

Whichever of the two error messages you got, you can try the troubleshooting options given below to fix the “DRIVER IRQL NOT LESS OR EQUAL or SYSTEM THREAD EXCEPTION NOT HANDLED, Netwtw04.sys failed” BSOD error.

Option 1 – Try to rollback your Network driver

Option 2 – Try to update the Network drivers

If the present Network driver is giving you a headache that is the “DRIVER IRQL NOT LESS OR EQUAL or SYSTEM THREAD EXCEPTION NOT HANDLED, Netwtw04.sys failed” BSOD error, then you need to update the Network drivers. To do so, here’s what you have to do:

• 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.
• Then right-click on each one of the Network drivers and update them all.
• Restart your PC and see if it helped in fixing the BSOD error.

Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

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 Netwtw04.sys failed BSOD 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 to 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.

Option 4 – 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.

Option 5 – Run 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.
