What is and how to Remove Shortcut Virus

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might be due to several reasons such as corrupted files, incorrect device driver configuration, malicious programs, outdated drivers, bad drivers, corrupted Windows Registry as well as some damaged or corrupted system files.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

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 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.

Interrupts are designed so that the resource requests don’t get into a headlock when it comes to the hardware level. To simply put it, it is used to break a loop that never ends. Aside from that, developers also designed levels in order to prioritize interrupts. It is also known as “Interrupt Request Level” or IRQL. And if you suddenly encounter a “Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL” error, this means that a driver has accessed a memory location illegally while NT is operating at a specific IRQL. The Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL is a fatal driver coding error and as an end-user, there isn’t much that you can do to resolve it but if you’re a developer, then this means that your code is trying to access an invalid memory location. You could check on different parameters such as memory location that was referenced and code addressed which referenced memory. The technical parameters are:

• a memory location that was referenced
• IRQL at time of reference
• 0 = read, 1 = write
• code addressed which referenced memory

As mentioned earlier, if you are an end-user, there is nothing much that you can do to resolve this problem, but worry not for there are still possible solutions that could help you in fixing it. Refer to the suggestions laid out below to fix Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL error.

Option 1 – Try running the Hardware and Devices Troubleshooter

The first thing you can do to fix the problem is by running the Hardware Troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the problem. To use it, refer to these steps:

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 2 – Try to update or rollback your device 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 – Run the Memory Diagnostic Tool to check for Memory leaks

• Tap the Win + R keys to open Run and type exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Note: After you select the option, your PC will restart and check for memory-based issues. If it finds any issues, it will automatically fix them and if there’s no issue found, then it’s most likely not a memory-based issue so you should try the other options given below.

Browsing your files on a computer seamlessly is made possible by the File Explorer in Windows 10 as it provides users with a great sense of customization for both listing and performing operations on a file. You have the option to arrange the folders and files being browsed by their name, type, date, size, and so on. Moreover, files that share a common attribute can be also be grouped accordingly using the grouping feature. However, there are times when instead of helping, it causes some problems for some users. This is why in this post, you will be guided on how you can disable the File Grouping feature in the File Explorer in Windows 10. There are two methods you need to consider in disabling the File Grouping feature in Windows 10. First, you can disable it for only one folder or you can disable it for all the folders on your computer. For more details, follow the instructions given below.

Option 1 – Disable File Grouping in only one folder

This first option is relatively straightforward and simple which will work if you only want to disable File Grouping in one folder.

• First, open File Explorer, and go to the folder you want to disable File Grouping.
• Next, right-click anywhere on that folder.
• And then select Group by > None. This will disable File Grouping for only that particular folder.

Option 2 – Disable File Grouping in all the folders

If you wish to disable File Grouping in all the folders on your computer, then you need to follow this option. If you have already tried the first one, then continue with the given steps below.

• Tap the Alt + V key combination.
• Then tap the Alt + Y keys and then tap Alt + O keys.
• After that, navigate to the View tab, and under the Folder views section, select Apply to Folders.
• Now click on the Apply and OK buttons to save the changes made. This will disable File Grouping in all the folders listed in the File Explorer.

If Error Code 0xc00000e9 appears on your screen, there is no cause to panic yet as there are different ways to fix this. Here, I will list down different methods to get your computer back on track:

1. Check peripheral connections
2. Check your SATA cables
3. Check your hard drive
4. Check your BIOS settings

Quick Fix 1. Check Peripheral Connections

1. Turn off your computer.
2. After the computer has been shut down, take off all the peripherals or the USB cables that are connected to your USB ports. This includes even the keyboard and the mouse. We just need to have only the monitor plugged in for this one.
3. Turn on your computer and see if it starts as it normally does.
4. If it does, try connecting back your external devices or peripherals one by one until you find the one that causes the error.
5. Once you trace the device that’s causing the error, you will have to change its USB cable and update its driver to support your operating system.

Quick Fix 2. Check your SATA cables

It is possible that what causes a barrier between your operating system and your hard drive from communicating is the SATA cable used. For example, if you’re using an older SATA with a SATA III port, there might not be adequate support for the transfer of data from one another. Or, the problem might be a loose SATA cable which would still require you to buy a new one to replace your loose or damaged cable. To check if your SATA cables are causing the error, simply follow these steps:

1. Turn off your computer.
2. Carefully open its case.
3. Check the hard drive and the SATA port where it’s connected.
4. Try to use a newer cable and connect it to your SATA port. (If you used a SATA II cable, you can see if a SATA III cable is more compatible.)
5. Replace your SATA cable with a newer one if Step 4 proves to be successful.

Quick Fix 3. Check your hard drive.

1. Try to use a different hard drive and see if error code 0xc00000e9 still appears.
2. If it works out just fine, then the problem might be physical damage to your hard drive and would need to be repaired depending on the case. Just simply take it to a technician and let him know about the issue.

Quick Fix 4. Check your BIOS settings

1. Restart your computer.
2. Once your computer starts, press and hold the ESC, F2, F12, or DEL key to go to BIOS settings.
3. You will then be redirected to the BIOS Setup Utility screen. From here, go to Boot options.
4. In the Boot Options, see if your first boot device is your hard drive. If it isn’t, press the arrow key to select the hard drive and move it to the top of the boot device list.
5. Save the settings.
6. Reboot your computer.

Note: If all the methods above do not work, the problem might be on your drivers and you might need to update them. You can update your driver in two ways: Manual driver update and Automatic driver update. You can find procedures online in updating your drivers.

Stable Diffusion is a machine learning model developed by Stability AI to generate digital images from natural language descriptions. The model can be used for different tasks like generating image-to-image translations guided by text prompts and upscaling images.

Unlike competing models like DALL-E, Stable Diffusion is open source and does not artificially limit the images it produces. Stable diffusion was trained on a subset of the LAION-Aesthetics V2 data set. It can run on most consumer hardware equipped with a modest GPU and was hailed by PC World as "the next killer app for your PC".

Since Stable Diffusion is run locally and not in the cloud, as mentioned there is no limit to the number of images that you can produce but in order to use it you will have to get down a little dirty with setting your PC environment for it since it is not really an application, it is a command line text based descriptor that will use python to generate your images, so there is no install nor GUI.

In this guide, we will show you how to both install and run Stable Diffusion on your local PC so you can start producing some cool images all by yourself.

Hardware and software requirements

Make no mistake, Stable Diffusion will not run on a potato PC, in order to harvest the power of AI-generated imagery this is what you will need:

• A GPU with at least 4GB of VRAM
• 10GB of hard disk space
• Python and libraries (Miniconda3 installer will install everything you need)
• The Stable Diffusion files
• Git
• Any OS (Windows, Linux, macOS)

Installing components

For this tutorial, we are covering the installation and running of Stable Diffusion on Windows PC. The steps presented here are presented in a way that installation can be performed on any operating system but precise instructions will be for Windows OS.

GIT

The first thing to do is to install GIT. It is a tool that will let you easily maintain and install repos from the internet. to install it go to: https://git-scm.com/ and click on download. Follow the instructions for your version of the operating system. If you are a developer you are familiar with GIT and if you already have it installed you can skip this step.

One thing that is important when installing GIT locally is to select to use it via the command line (the second option that says "Git from the command line and also from 3rd-party software").

Miniconda3

Now when we have GIT installed, next thing is to use Miniconda3 to install python and all required libraries that are needed. Get the installer at: https://docs.conda.io/en/latest/miniconda.html

Miniconda3 is basically an easy installer so you do not have to install tons of stuff manually from different websites and sources, it is nicely packaged in the installer that will take care of everything.

Stable Diffusion

After the previous two steps, we are ready now to actually install Stable Diffusion. Go to https://huggingface.co/CompVis/stable-diffusion#model-access and install the latest library (as of the writing of this article currently it is stable-diffusion-v1-4-original, the last one on the right), the library is almost 5GB in size so be prepared for big download.

After installing stable diffusion's latest library it is time to update it to the newest version. You can download ZIP from GIT HUB https://github.com/CompVis/stable-diffusion

Once downloaded click on the Windows start button and type in Miniconda3 and click on open. Create a folder and name it how you want on a drive of your choice. For this example, we will install it all in disk C under folder AI_art, follow the instructions below but use your own names and destination instead. Do not close Minicoda3 after typing commands!!!

cd c:/
mkdir AI_art
cd AI_art 

Extract GitHub files that you have downloaded into your new folder and get back to Minicoda3 and type the next commands:

cd C:\AI_art\stable-diffusion-main
conda env create -f environment.yaml
conda activate ldm
mkdir models\ldm\stable-diffusion-v1

Let the whole process finish, some files are large and it might take a while. After the whole process is finished and completed, copy the checkpoint file that you have downloaded into: C:\AI_art\stable-diffusion-main\models\ldm\stable-diffusion-v1

After the file is copied rename it to model.ckpt and you are finished.

Running Stable Diffusion

The created environment is needed in order to actually use Stable Diffusion to create images. Each time you want to use it you will have to run it, so go into Miniconda3, and inside it type:

conda activate ldm
cd C:\AI_art\stable-diffusion-main

after we are inside the folder call the script with the parameters:

python scripts/txt2img.py --prompt "TXT DESCRIPTION OF IMAGE THAT YOU WANT TO CREATE" --plms --n_iter 5 --n_samples 1

and that's it, your image is created and it is located in C:\AI_art\stable-diffusion-main\outputs\txt2img-samples\samples

As you know, Diskpart is a useful utility that helps in managing the disks in a computer. It is a very useful tool that even when the GUI-based disk management tools in Windows 10 operating system fails, the Diskpart utility still tends to work. However, it also does not mean that this utility does not experience issues as it still does, from time to time. One of the issues you may encounter when using the Diskpart utility is when you encounter an error message that says, “DiskPart has encountered an error, Access is denied”. This kind of error in the Diskpart utility could be caused by a number of factors. For one, it could be that the Write-Protection is enabled on the drive where the operating is being performed or it could also be that the Command Prompt terminal does not have administrator-level permissions to carry out the command. Thus, you can try to run the Diskpart utility again but this time with admin privileges or you could also remote the Write-Protection from the concerned drive. For more details, refer to the instructions given below.

Option 1 – Try running Command Prompt with Administrator-level permissions

• In the Start Search, type “command prompt” and from the search results that appear, look for Command Prompt.
• Once you found it, right-click on it and select the “Run as administrator” option.
• After that, try to execute the Diskpart operation once again and see if you still encounter the same error.

Option 2 – Try to remove the Write Protection from the drive

As mentioned, removing the Write-Protection on the concerned drive could also help you fix the problem and there are two ways to get rid of the write protection – you can either use the Diskpart utility or the Registry Editor. How? Refer to the following steps.

Via Diskpart utility:

• Open Command Prompt with admin privileges and then type the “diskpart” command and tap Enter to execute it.
• Next, type “list disk” and tap Enter to get the list of all the Disk connects or all the partitions that are formed on those disks.
• After that, you need to choose one command depending on the list of commands you entered. Type “select disk #” and tap Enter to select the disk or partition you want to select.
• Then type “attribute disk clear readonly” and tap Enter to Disable the Write Protection on the selected disk or partition.

Via Registry Editor:

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to the following registry key:

ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStorageDevicePolicies

• After that, look for the DWORD named “WriteProtect” and double click on it, and then set its Value Data to “0”.
• Now restart your computer and see if the problem is now fixed or not.

What is Windows Update Error 0xC1900209? Before you can install any updates on your Windows 10 computer, there are a lot of conditions that have to be fulfilled and one of these conditions is software compatibility. It is one of the important factors in installing Windows Updates. So if one of the software in your computer is not compatible with the new Windows Update for your OS, then the Windows 10 setup will not proceed and will block the installation of the new update. This both applies to the cumulative updates and feature updates. In such cases, you will get the following error message when you run Windows Update:

“0xC1900209, Incompatible software is blocking the upgrade process. Uninstall the application and try the upgrade again.”

This error message comes under the umbrella of the Windows 10 pre-upgrade validation using Setup.exe. And for you to identify the incompatible app, you need to grab a Windows 10 install image using the Windows Media Creation tool to download the suitable Windows 10 version and mount it. After that, execute the setup.exe file that’s located in the root folder of the Windows 10 install image. Once you execute the setup file, the upgrade wizard will give you a list of incompatible apps. Once you have determined which software is not compatible with the Windows Update, there are two options you can try to resolve the Windows Update error 0xC1900209 – you can either try to update the conflicting software or uninstall it. For more details, follow the given options below.

Option 1 – Try to update the conflicting software

If you are using an older version of the software that’s in conflict with the Windows Update, you might want to update it to its latest version and then try to apply the updates again to your Windows 10 computer. You can update the concerned software by visiting the official website of the software or any of its distribution sources. On the other hand, you can also use the Check for updates feature of that particular software if it’s available.

Option 2 – Try to uninstall the conflicting software

If updating the problematic program didn’t work, the next option you can try is to uninstall it. All you have to do is follow these steps to uninstall it successfully:

• Tap the Win + R keys to open the Run dialog box.
• Then type “appwiz.cpl” in the field and tap Enter to open the Programs and Features in Control Panel.
• Next, arrange the list of installed programs in the order of the installation date.
• After that, look for the problematic program and right-click on it, and then select Uninstall.
• Once the uninstallation process is done, restart your computer and see if the Windows Update error 0xC1900209 is fixed or not.

The Windows Defender program can both scan and monitor almost the entire folder on a Windows 10 computer. So if you have a folder that may have files that could trigger an alarm to Windows Security, then it would be better if you add an exclusion to Windows Security. Note that it is okay to do this as long as you’re certain that the contents of the folder you want to exclude are safe and that Windows Defender is only throwing out warnings for nothing. This way, Windows Defender won’t scan those folders in the future. And besides, there are also some Windows folders and files that you may exclude from the Antivirus scans, especially if you want to save your scan time. This kind of feature also comes in handy when you trust a file type or folder or any process that you believe is safe but the Windows Security considers as malicious. To exclude a folder or a file or process or a file type from the Windows Security scan, here are some steps you can follow. Make sure to do them carefully. Step 1: Search for “Windows Security” in the Search box and then click on it from the search results to open it. Step 2: Next, click on Virus & threat protection > Manage settings > Add or remove exclusions. Step 3: After that, on the next screen, click on Add an exclusion > Folder. It will show you a list that includes File, Folder, File Type, and Process. Step 4: Now click on “+Add and exclusion” on the next window and then select a folder you want to exclude and click OK to add it in the Exclusions list. Step 5: Click on the down arrow button to remove it and then click on the Remove button. Note: If you want to only ignore a few file types, it’s better if you configure your antivirus program to ignore these files with a specific extension. This way, it will ignore all of them no matter what their location is. Also keep in mind that when you select a folder, all the subfolders in it will also be excluded from the scan. Thus, you need to understand what you’re about to do. Once you’re done excluding the folder, it is recommended that you protect the folder using the Controlled Folder Access since this folder is not monitored for threat. The Controlled Folder Access will ensure that an external program does not alter it. This way, you can be sure that even though this folder is not included in the scan, it is still secure.
