Fix Netwtw04.sys BSOD Error in Windows 10

What Is 0x00000050 Stop Error?

While running your Windows 7/Windows Server 2008 R2, your system suddenly stops responding out of complete randomness and you see an error message popping up which says something like this:

0x00000050 (parameter1, parameter2, parameter3, parameter4)

Solution

Error Causes

The stop error 0x00000050 signifies that there’s a PAGE_FAULT_IN_NONPAGED_AREA problem. If you’ve seen this error on different occasions then you will find the parameters in the message to be varying. That is because they are dependent on your PC’s configuration. Not all Stop errors "0x00000050” occur due to a single issue.

However, the most common problem which is encountered which results in the stop error popping up is due to a pool corruption occurring in the Srvnet.sys file.

This issue might be caused because of software incompatibility or a defective physical memory which resulted in requests for data for a hardware driver or service which was not found in the memory.

If you find the error occurring after you’ve installed a new application or a device driver then you should access Safe Mode and uninstall, disable or remove that application or driver.

Further Information and Manual Repair

In order to fix this issue, you should try booting your computer to the “Last Known-Good Configuration” as listed during startup.

For this you have to follow the below-mentioned steps:

1. Start your system.
2. When you see the message which says “For Troubleshooting And Advanced Startup Options For Windows, Press F8” hit F8 and proceed.
3. Use the up and down arrow keys to highlight “Last Known-Good Configuration” and hit enter (This method will only work if your system boot was not successfully carried out ever since you made any specific changes).
4. When you are starting the computer, press F12 and proceed with the PSA/32 Bit Diagnostics.
5. Do the following so that a clean boot can be performed:

• Go to the Start menu when the Windows 7 desktop shows up.
• On the search bar, type “msconfig” and hit search.
• Disable all the applications which are listed on the “Startup” tab.
• Now head over to the “Services” tab and mark the option which reads "Hide all Microsoft Service".
• Select the “Disable All Services” option.
• Apply the changes by clicking on “Apply” then restart your PC. You should now check the performance of your computer. If you don’t see a BSOD then you start re-enabling all the Services and Startup applications one by one until you finally figure out which one is causing the BSOD to appear.

6. Update your Windows with “Windows Updates”.

As you know, Microsoft constantly releases new updates with the main goal of fixing bugs as well as deliver users with new and exciting features. However, there are times when the latest update comes with an unwanted bug. One of these bugs is an error message saying, “Low Disk Space. You are running out of disk space on Local Disk (G:). Click here to see if you can free space on this drive.” So if you have recently installed a Windows 10 update, then you’ll most likely see a completely new drive on your computer which will appear right after the installation of the update and you’ll also start seeing the aforementioned error message. It gets irritating as this error message keeps on popping up even if you still have a lot of free space on your other drivers. Obviously, the main reason why this error message pops up all the time is the bug brought along by the Windows Update. This bug unhides the recovery partition drive and allocates it a drive letter which is why you are seeing a new drive in your computer. Thus, you can get rid of the pesky error message by simply removing the letter of the new drive. Just remember that you must not delete anything from the recovery partition drive nor format the drive. Formatting or deleting the recovery partition drive can heavily affect the recovery of Windows since the data on the drive is used by the Windows Recovery Environment or your system’s manufacturer. A lot of users have reported that removing the drive letter has resolved the issue. And if you worry that removing the drive letter will delete the drive, you are mistaken. This solution is basically harmless and is proven effective to make the notifications go away. Carefully follow the instructions below to get rid of the Low Disk Space notification by removing the drive letter.

• Step 1: Tap the Windows key once.
• Step 2: Next. In the Windows Start Search, type in “command prompt” and right-click on Command Prompt from the search results and select the “Run as administrator” option or you could simply tap Win + R keys and then input “cmd” and hit Enter to open Command Prompt.
• Step 3: After opening Command Prompt, type in “diskpart” and tap Enter.
• Step 4: Next, type in “list volume” and tap Enter. After that, you will see a list of drives.
• Step 5: Take note of the letter associated with the newly created drive.
• Step 6: Afterwards, type in “select volume <drive letter>” and tap Enter. Take note that you must replace the <drive letter> with the drive letter you’ve found in Step 5.
• Step 7: Now type in “remove letter=<drive letter>” and then tap Enter. Once again, replace the <drive letter> with the letter you took note of in Step 5.

100sOfRecepies is a Browser Extension developed by MindSpark Inc. that provides users with hundreds of recopies for breakfast, lunch, dinner, and dessert. This extension may appear very handy at the start, however, it may monitor your browser activity, and send it back to the developer to better serve ads. This extension injects itself into the System Registry allowing it to run each time your computer is restarted.

While browsing the internet with this extension installed you may see additional ads, sponsored links, and pop-up ads displayed in your browser. Many anti-virus scanners have detected this extension as a Browser Hijacker and are therefore not recommended to keep on your computer.

About Browser Hijackers

Browser hijacking is actually a form of an unwanted program, often a web browser add-on or extension, which causes modifications in browser settings. They are made to disrupt web browser programs for various reasons. Usually, it’ll force users to predetermined sites which are aiming to increase their advertisement income. Nevertheless, it’s not that harmless. Your internet safety is compromised and it is also very annoying. In a much worst case, your browser could be hi-jacked to download malware that may do a great deal of damage to your laptop or computer.

Major symptoms that your web browser has been highjacked

The typical symptoms that indicate having this malware on your computer are: 1. the browser’s home page is changed 2. bookmark and the new tab are also modified 3. the default search engine is changed and the browser security settings have been lowered without your knowledge 4. find new toolbars which you did not add 5. unstoppable flurries of pop-up ads show up on your personal computer screen 6. your web browser gets slow, buggy crashes often 7. Inability to navigate to certain websites, particularly anti-malware and also other security software webpages.

How does a browser hijacker infect a computer?

There are several ways your computer can become infected with a browser hijacker. They generally arrive by way of spam e-mail, via file sharing websites, or by a drive-by-download. They could also come from add-on software, also known as browser helper objects (BHO), web browser plug-ins, or toolbars. Some browser hijackers spread in user’s computer systems using a deceptive software distribution technique known as “bundling” (generally through freeware and shareware). An example of some well-known browser hijacker includes Babylon, Anyprotect, Conduit, DefaultTab, SweetPage, RocketTab, and Delta Search, but the names are continually changing. Browser hijackers could record user keystrokes to gather potentially valuable information that leads to privacy issues, cause instability on computers, drastically disrupt the user experience, and eventually slow down the PC to a point where it will become unusable.

Browser Hijacker Malware – Removal

Some browser hijacking could be quite easily stopped by discovering and eliminating the corresponding malware program from your control panel. But, most hijackers are hard to get rid of manually. No matter how much you try to remove it, it can come back over and over. Moreover, browser hijackers could modify the Computer registry so that it could be very tough to restore all of the values manually, particularly when you are not a very tech-savvy person.

You have the option to choose to configure the Network to Private or Public when you set it on Windows 10 PC. On the other hand, if the option to change the Network from Public to Private goes missing in Windows Settings then this post will surely help. You can find this setting under Settings > Network and Internet > Ethernet and appears when you click on it. If you are not able to see the option to change the network profile, then you either can’t open the settings, or the option to change it has been disabled. To resolve this issue, you can either use the Registry Editor or Windows PowerShell. Refer to the options given below for more details.

Option 1 – Change the Network Profile via Registry Editor

Changing the Network Profile can be done using the Registry Editor. But before you proceed, make sure that you create a System Restore Point first just in case. Refer to the steps below to do so.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to this key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionNetworkListProfiles
• Now expand the Profiles key folder located in the left pane to see one or more folders.
• Next, expand each one of these folders and look for the “Description” sub-key which should match the name of your network.
• After you find the Description sub-key, look for another sub-key named “Category” and double click on it to open it.
• Now change its value from “0” to “1” to change the Network Profile from Public to Private.

Option 2 – Change the Network Profile via Windows PowerShell

Aside from the Windows Registry, you can also use Windows PowerShell in changing the Network Profile from Public to Private and so on. Take note that you have to use PowerShell with admin privileges. Just refer to the steps below to do so.

• Tap the Win + X keys and then select the “PowerShell (Admin)” option.
• Next, click on Yes if the User Account Control prompt appears.
• After that, execute the commands listed below. Hit Enter right after you key in each one of them.
  • Get-NetConnectionProfile
  • Set-NetConnectionProfile -InterfaceIndex <index number> -NetworkCategory Private

Note: Since every Network Profile has an index number, you can check the label “Name” to identify the network that you want to change.

BSOD or Blue Screen of Death errors are one of the toughest issues you can encounter in Windows 10 as well as the hardest ones to resolve as they simply shut the system down or restart it abruptly and claims that it isn’t possible to boot Windows again. One of the difficult BSOD errors is the Machine Check Exception BSOD error. The reason why it is hard to fix is that in most cases, it occurs soon after Windows loads which gives users little to no time in resolving it. To make things worse, the system also freezes right before it displays the blue screen error and shuts the system down. Usually, the Machine Check Exception Stop error occurs due to the failure or overstressing of the hardware components. And in the case of almost all Blue Screen of Death errors, the issue usually has something to do with the drivers. So if you frequently see this BSOD error from time to time, now’s the time to act on it by following the solutions given in this post.

Option 1 – Update the Device drivers

• 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. Look for the device driver you and then select either “Update driver” or “Uninstall device”. 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.
• If you have chosen to uninstall the driver, follow the screen options to complete the process and then restart your PC.
• Connect the device and Scan for hardware changes – you can see this option under Device Manager > Action.

Option 2 – Try running the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 3 – Try running the System File Checker

System File Checker or 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 that might be causing the Machine Check Exception BSOD error. 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 Startup Repair

In the Blue Screen where the Machine Check Exception error is displayed, tap the F8 key to go to the Startup Settings where you can find Startup Repair and then run it. Note that this is a must-try option especially if you are unable to start your computer and if you can use your computer for a few moments.

Option 5 – Run the DISM tool

There are cases when the Machine Check Exception error is caused by the Windows System Image so you need to repair it using the DISM or Deployment Imaging and Servicing Management 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 /CheckHealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 6 – Try resetting the BIOS

If you have made some modifications in the BIOS that might have caused this error, you have to revert those changes to resolve the issue. On the other hand, if you have made a couple of changes and you do not remember which is which, you might have to reset the BIOS.

Option 7 – Try resetting Windows 10

To fix this BSOD error, you can try resetting Windows 10. Doing so won’t get rid of any file in your system – instead of erasing all your media files and documents, this reset option resets all the system settings and files.

If you are typing inside the Search bar, Cortana, Taskbar, Windows 10 apps, etc., and then everything seems invisible then read on as this post will guide you in fixing this issue. At first, you might think that something is wrong with your keyboard but it really has nothing to do with it. The problem actually lies with the apps from Microsoft Store. Thus, if you can’t type anything in any of the apps from Microsoft Store in Windows 10, refer to the options given below to fix them.

Option 1 – Ensure that ctfmon.exe is running

Ctfmon.exe is a Microsoft process in Windows 10 that controls the Alternative User Input as well as the Office Language bar. In other words, it enables end-users to control the computer using on-screen keyboard inputs, speech, and even pen for various languages. It would be better if you launch the program once by going to the C:/Windows/system32 folder. Doing so will ensure that whatever API is needed for the keyboard typing to work properly again. You also have to make sure that its startup status is not disabled. In addition, you can also try the following steps, alternatively.

• Open the Task Scheduler.
• Then go to Microsoft > Windows > TextServicesFramework.
• And on the MsCtfMonitor, right-click and enable the task.
• Now restart your computer.

This will ensure that all the text boxes will start to work again. And if the task MsCtfMonitor is missing from the list of tasks, you can import it with the XML file from basics.net. Then download and create a task to run it each time you log in to your PC.

Option 2 – Use the Windows Store Apps Troubleshooter

You might also try running the Windows Store Apps Troubleshooter as it can help in resolving issues with the Windows Store apps. This built-in tool can resolve most of the app-related problems. To use it, go to Settings > Update & Security > Troubleshooting > Windows Store Apps and from there, click the start the troubleshooter button. The Windows Store Apps Troubleshooter will scan the computer for any issues with the Windows store apps and will automatically fix them if it finds any.

Option 3 – Re-register all the Windows 10 UWP apps using PowerShell

• First, make sure to close all the running applications on your computer.
• Next, in the Start search, type in PowerShell and right click on the result, and select the “Run as administrator” option.
• After that, type the following commands to re-register the Windows 10 apps. Make sure to hit Enter on each line:
  • reg delete "HKCUSoftwareMicrosoftWindows NTCurrentVersionTileDataModelMigrationTileStore" /va /f
  • get-appxpackage -packageType bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + "appxmetadataappxbundlemanifest.xml")}
  • $bundlefamilies = (get-appxpackage -packagetype Bundle).packagefamilyname
  • get-appxpackage -packagetype main |? {-not ($bundlefamilies -contains $_.packagefamilyname)} |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + "appxmanifest.xml")}

Option 4 – Try to run the DISM tool

You can also run the DISM Tool as it helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” which could help in fixing the problem.

• 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 5 – Run the System File Checker Scan

System File Checker or 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:

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.

• Restart your PC.

Windows uses 2 types of keys for its activation, KMS or MAK. These keys should work without any issues since they are elevated with higher permissions but in some cases, they are by accident run without their proper permission, and then we have access denied error or error 0x80070005 To resolve this issue please first check if not by any chance your antivirus or firewall is preventing slmgr.bs file to access the right permissions, that being said if the previous solution is not working note that you have to be an administrator of the system or have administrator privileges. As an administrator, you will have to use Software Licencing Management Tool or short SLMGR.VBS, a VBS file in Windows used for its activation purposes. As an administrator, open Command prompt with admin permissions and then run slmgr.vbs This will make sure that activation goes through, make sure to use proper options like:

/ipk <ProductKey> or /ato [<Activation ID>]
