Installing Wi-Fi drivers in Windows

So, what is Electron bot, and why it even matters if it is in the MS store. Electron bot is malware that somehow found its way inside MS Store via game clones of popular games temple run and subway surfer. This infiltration led to the infection of around 5000 systems over the globe in a very short period of time.

This malware is a backdoor that gives complete system control to the attacker. Any type of execution can be performed remotely in real-time. Usually, this kind of attack was aimed at a spread of click fraud over popular social media like Facebook, google, youtube, etc.

Primary goal

Electron Bot's primary goals in the ongoing campaign analyzed by researchers are:

• SEO poisoning – Create malware-dropping sites that rank high on Google Search results.
• Ad clicking – Connect to remote sites in the background and click on non-viewable advertisements.
• Social media account promotion – Direct traffic to specific content on social media platforms.
• Online product promotion – Increase store rating by clicking on its advertisements.

These functions are offered as services to those who want to increase their online profits illegitimately, so the gains for the malware operators are indirect.

Publishers that contain malware

For now, users may take note of the publishers who released confirmed malicious game apps using the following names:

• Lupy games
• Crazy 4 games
• Jeuxjeuxkeux games
• Akshi games
• Goo Games
• Bizzon Case

If you were having some problems with your internet connection and you tried to run the Internet Connections troubleshooter but it displays an error message instead that says, “The default gateway is not available”, read on as this post will show you what you can do to fix this error. The first thing you can do to fix this error is to restart your computer and then try to run the Internet Connections troubleshooter again. However, if you still see the same error message, then you might want to troubleshoot the problem further. You can try to install the Network driver or reinstall the Network adapter drivers. You could also verify the power saving mode or reset TCP/IP as well as disable the Firewall temporarily.

Option 1 – Try installing the Network driver

The very first thing you can do to resolve the error is to install the network driver. It is a common solution to this kind of problem and most users encounter it right after a fresh installation of Windows 10. So if you have done this, then you need to install the network driver so that the network adapters can start working. You can find the network driver in the motherboard CD. On the other hand, if you are using a laptop, you might have to use another computer or mobile to download the network driver from the manufacturer’s website.

Option 2 – Update the Network Adapter drivers

If the first option is not applicable to you since you already have network drivers in your computer, you might want to update the Network Adapter drivers by following these steps:

• Tap the Win + R keys to launch the Run window and then type in the “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 them.
• 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 “Windows could not find a driver for your network adapter” error, 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.

You could also try to reinstall the network adapter driver, refer to these steps:

• 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.

Option 3 – Try to verify power-saving mode

If you are using a Windows 10 laptop, then you should know that the Power Options panel plays an important role. So if you’re getting an error in your laptop, you have to check some settings that are related to the Power Saving mode. To do so, follow these steps:

• Open Control Panel and go to Hardware and Sound and click on Power Options.
• Next, click on the “Change plan settings” option of your selected plan and then click the “Change advanced power settings” option.
• After that, you should see the Power Options window, and here, expand the Wireless Adapter Settings and Power Saving Mode.
• Now make sure that the Maximum Performance option is selected. If it’s not, select it and save the changes you’ve made.

Option 4 – Try to reset the TCP/IP

As you know, the TCP/IP or the Internet Protocol is the most important thing if you want to use the internet on your computer. That’s why if it ends up getting corrupted, you need to reset the TCP/IP to fix the problem. To reset TCP/IP, refer to these steps:

• In the Windows start the search, type “command prompt” and right-click on Command Prompt from the search results.
• Then select the “Run as administrator” option to open Command Prompt with admin privileges.
• After that, execute this command: netsh int ip reset resettcpip.txt
• Once it’s done, exit Command Prompt and restart your computer and then check if the error is now fixed.

Option 5 – Temporarily disable Firewall

On the other hand, the error could also be due to the Firewall software installed on your computer. Thus, disabling them or any security software installed on your computer is always a good idea you can try when you’re not able to access the shared drive on your computer. There are times when you encounter problems like the error “The default gateway is not available” due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program and Windows Defender Firewall for the meantime and check if it fixes the error or not

Update and Shutdown/Restart is not working. As you have probably noticed, every time a new update is released and is downloaded on your Windows 10 computer, the operating system replaces the Restart and Shut down button with “Update and Restart” as well as “Update and Shut down”. This is most likely done so that you won’t miss the update. However, some users noticed that there are times when these buttons still continue to display the same message even if they’ve already performed the required operations such as shutting down or restarting their PCs. Cases like this happen when an update wasn’t installed properly or has failed which is why your computer keeps on prompting you to Update and Shutdown every time. To fix this dilemma, follow the options laid out below.

Option 1 – Try restarting the File Explorer

Restarting the File Explorer can definitely help you fix lots of issues especially when there is some issue with the user interface including this one.

• On the right side of the Taskbar, right-click on any open spot.
• Then click on Task Manager.
• Next, scroll down until you see Windows Explorer.
• After that, right-click on it and select Restart.
• If you are able to kill its process, you have to tap the Win + R keys to open the Run dialog box and type “explorer.exe” in the field, and hit Enter to launch the Windows Explorer.

Option 2 – Try running the Windows Update Troubleshooter

As you know, Windows 10 has various auto-repair built-in tools to help users fix small issues which used to get fixed manually. And in this case, you will need the Windows Update Troubleshooter to fix the issue.

• Go to Settings and click on Update and Security.
• From there, click Troubleshoot and click on Windows Update and then click the “Run the troubleshooter” option.
• After that, it will try to detect and automatically fix common issues in the Windows Updates which can be resolved by Windows itself. Note that the process may take several minutes before it completes so you need to wait until it’s done. Once it’s done, in case you have some pending update that wasn’t realized by the system early on, it will apply the fix right away and restart the Windows Update service.

Option 3 – Try setting the Power button to Shut down

In case the first two options didn’t work out, you can try changing what the power button does. To do that, refer to these steps:

• Go to Control Panel > Power Options.
• From there, select the “Choose what the power buttons do” option from the left side.
• Then set the Power button setting the “When I press the power button” option to “Shut down”. After that, it will shut your computer down without installing the updates but obviously, this is only a temporary fix.

Option 4 – Turn off your PC instantly without updating it

• Tap the Win + R keys to open the Run dialog box.
• Type in “shutdown -s -f -t 0” in the field and hit Enter if you really want to turn off your computer without any delay.
• You could also tap the Ctrl + Alt + Del keys and select Shut down from the bottom right menu.

Just like the third option, this is also only a temporary fix.

Option 5 – Try running the Windows Module Installer

The Windows Module Installer is a built-in service in Windows 10 that allows you to fix the stuck Windows Updates in your computer. To use it, follow these steps:

• In the Cortana search box, type in “cmd” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option from the context menu.
• Once you’ve opened Command Prompt as admin, type the SC config trustedinstaller start=auto command and tap Enter.
• After the command is executed, you will see the “[SC] ChangeServiceConfig SUCCESS” message displayed on the Command Prompt console.
• Now exit Command Prompt and then check if the buttons are now back to normal.

Option 6 – Put your PC in a Clean Boot State

• 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” checkbox 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.)

After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

• From the “Start” menu, go to System Configuration.
• After that, switch to the General tab and click the option for “Normal Startup”.
• Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
• Then find and click “Enable all” and if prompted, you have to confirm.
• Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
• Restart your PC when prompted.

If you are a gamer, you might have encountered either the CID HANDLE CREATION or VIDEO TDR ERROR errors with an error code of 0x00000016 as you play a game. These kinds of Stop errors have something to do with the Graphics card driver. It could be that your Graphics card driver needs to be updated or it may be corrupted. Whichever the case is, you can try fixing this error using the given solutions below but before you proceed, make sure to create a System Restore Point first so that you can easily roll back to the previous state of your computer in case something does not go as expected.

Option 1 – Try checking if your graphics card is enabled and update it as well

Although the problem is quite massive, the fix could be as simple as enabling the graphics card if it turns out to be disabled.

To do so, follow these steps:

• Tap the Win + R keys to open the Run dialog box.
• Then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• After opening the Device Manager, look for your graphics card option among the list of device drivers. Once you found it, check if it is enabled or not. If it’s not enabled, you should see a gray arrow pointing downwards. Right-click on the card and select Enabled.

• Now restart your computer.
• Once your computer has restarted, go to the GPU manufacturer’s website and download the latest driver version for your graphics card model and then install it.
• Restart your computer once again. That should fix the problem.

Option 3 – Try reinstalling the game

If updating and reinstalling your Graphics card driver didn’t help, then you can try to reinstall the game where you’re getting the CID HANDLE CREATION or VIDEO TDR ERRORS.

Option 4 – Uninstall the programs you installed recently

Chances are, some programs that you just installed might be the one that’s causing the BSOD error. Thus, you need to uninstall the program to resolve the problem.

• 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. In addition, you might also want to check the hardware components of your computer that might not support the operating system itself. You can disconnect all the external devices like USB drives, scanners, printers, etc., and then reboot your PC. After that, add the devices again one after the other and check if the BSOD error is now fixed or not.

Option 5 – Try disabling your monitor’s Sleep functionality

There are times when the Sleep functionality of your monitor can also cause BSOD errors like CID HANDLE CREATION or VIDEO TDR errors. There are also times when the graphics card is running in the background and the display goes to sleep and then it’s turned back on but you encounter this kind of Blue Screen error. This is why you can try to disable your computer monitor’s Sleep mode.

Option 6 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like CID HANDLE CREATION or VIDEO TDR errors. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

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.

High Dynamic Range or HDR is a technique that’s used to create lifelike videos which have improved and better dynamic range, especially when it comes to details. And as you know, Windows 10 supports the steaming of HDR videos as long as the display supports it and it comes with the option to enable the HDR Playback for Windows 10 Video Streaming apps. However, before you can get the best viewing experience, you need to calibrate the display further for HDR video on your Windows 10 PC. Take note that even when you have the HDR Playback feature enabled on your computer, you still need a display that supports it. To make sure that your display supports this feature, you can use the DirectX Diagnostic Tool to have the display correctly wired and have the latest WDDM 2.4 drivers installed as well as set the other settings properly. Once you’ve made sure that your computer’s display really supports HDR and you’ve already enabled the HDR Playback feature, now it’s time for you to calibrate. Remember that when you calibrate the display, you should make an external monitor your primary display if you are using it for HDR and then adjust the settings to your liking. And if you are calibrating for primary display, you need to disconnect all other displays.

Follow the given steps below to calibrate the display of your PC.

• Step 1: You need to open the Video Playback first. To do so, navigate to Settings > Apps > Video Playback.
• Step 2: Under the Video Playback settings, uncheck the “Don’t increase display brightness when watching HDR video on battery” checkbox or plug in your PC.
• Step 3: Next, click the “Change calibration settings for HDR video on my built-in display” link located on the right side.
• Step 4: After that, click on the Play button located on the left side to play the video. Then move the sliders to the left or right so you can start to calibrate. Once you see that the quality of the image is to your preference, stop.

Note: Just a tip when calibrating – you just have to find the right balance between the details in the darker parts of a scene. For instance, you have Mountains in the background and buildings in the front – you need to drag the slider to the right to add more details to the snow on the mountain or drag the slider to the left to add more details to the buildings. After that, you can pause the video and exit the full-screen mode. Keep in mind that the quality of HDR depends on you as it is a personal choice. Some users might like a brighter shade while other ones want the darker shade so it really depends on your taste. If you are not satisfied with how your HDR turned out, you can just try calibrating the display again. Simply go back to the default HDR video calibration and click or tap the Reset calibration button. Another thing to remember. First, you can only see HDR content on the full screen and if you’re using a laptop, you need to make sure to watch videos when plugged in and check that the battery settings won't’ lower the brightness.

If you encounter a Blue Screen error that points out to the CMUDA.sys, read on as this post will guide you in fixing it. The CMUDA.sys file is a Windows operating system driver file that is related to the USB Device Audio capabilities of a computer. There are times when this file causes Blue Screen error due to some conflicts in RAM or some incompatible firmware or hard disk issues, corrupted drivers or malware infection, and so on. There are various Blue Screen errors that are related to the CMUDA.sys file such as:

• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN A NONPAGED AREA
• IRQL NOT LESS OR EQUAL
• SYSTEM THREAD EXCEPTION NOT HANDLED (CMUSBDAC.sys)

In most cases, the CMUDA.sys file usually triggers the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED Blue Screen error. Although this Blue Screen error may seem complicated, its workarounds are straightforward so you won’t have any problems in following them.

Option 1 – 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.

• 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. You can download the as C-Media USB Audio Class driver from the cmedia.com website.

Option 2 – Try to recreate the CMUDA.sys file

The first thing you can try is to recreate the CMUDA.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. Which is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.

• Boot your Windows 10 PC in Safe Mode.
• Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
• From there, look for the file named sys and rename it to CMUDA.old.

Note: As you can see, the file’s extension has changed from .sys to .old.

• Now restart your computer and check if the CMUDA.sys Blue Screen error is now fixed.

Option 3 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors. It 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.
• After that, 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.

On the other hand, you can also try running the online Windows 10 Blue Screen troubleshooter from Microsoft. It is a wizard that could help you fix any Stop errors related to the CMUDA.sys file and will offer you helpful links as you use it.

Option 4 – Try running the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Wdf01000.sys Blue Screen error. 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 5 – Run System Restore

Running System Restore might also help in fixing Blue Screen errors related to the CMUDA.sys file.

• 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.

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”.
