Fix MSVCR71.dll is missing in Windows 10

If you are trying to install a Windows 10 upgrade but was interrupted with an error saying, “0x80070003 – 0x2000D, The installation failed in the SAFE_OS phase with an error during MIGRATE_DATA operation”, then you’ve come to the right place as this post will help you sort this problem out. When you get this kind of error while trying to upgrade your computer, although there could be various reasons for this, the primary one is that when you upgrade from one update to another, something stopped the upgrade process to migrate the user data. To fix this error, you can try to run both the DISM tool and the System File Checker to automatically repair any corrupted system files. You could also try checking the free storage space of your primary drive and if you have any file lock apps like BitLocker, consider disabling them for they could also be the reason why you’re getting the error.

Option 1 – Run the DISM tool

Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10 which might be the reason behind the Windows Upgrade error 0x80070003 – 0x2000D. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt as admin.
• Then type in this command: 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.
• Once it’s done, restart your computer and then check if the issue is resolved or not on the next startup.

Option 2 – Run the SFC scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Windows Upgrade error to appear. 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 and hit Enter.

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Reboot your PC.

Option 3 – Try checking the free storage space on your primary drive

The next option you can try to resolve the error is to see if you have enough free storage space on the primary drive because if you don’t then it’s probably the reason why you’re getting this error. To fix it, you need to free up some storage space by following these steps:

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space.
• Now make sure that the Storage Sense feature is turned On then go find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
• Windows Upgrade Log Files
• System created Windows Error Reporting Files
• Thumbnails
• Temporary Internet Files
• Previous Windows Installation Files
• Delivery Optimisation Files
• DirectX Shader Cache

Note: Once you’re done freeing up space on your drive, try to run the setup file again.

Option 4 – Try disabling BitLocker and other file lock apps

If you are using BitLocker or other file lock apps, then it could be the reason why you’re getting the error. Usually, file lock apps don’t cause any kind of issue, however, if you have something that works on file level like BitLocker, you can try to disable it. Once you’ve disabled it, try to install the Windows 10 Upgrade again and after you do, enable BitLocker again. This should fix the problem.

Mapping network drive has many benefits in terms of speed and ease of access of files via network. It lets you access the hard drive over the whole network like it was the hard drive inside your PC case. In order to easily and quickly map a folder as a network drive follow the guide below.

1. Open File Explorer
2. Click on the three dots icon in the Toolbar
3. Select Map Network Drive
4. Click the Drive drop-down menu
5. Select a driver letter that you wish to assign as a network drive
6. In the folder field enter network device and share name (click on browse to see all devices on local network)
7. Check the box beside Reconnect at sign-in if you wish to automatically connect to a network drive on Windows startup
8. Check Connect Using Different Credentials if you wish to connect to a network drive using different credentials that one used to login into Windows.
9. Click Finish

After finishing setting Windows 11 will try to connect to the network drive and if successful drive icon will appear inside File Explorer and the drive will open up to see its content. If for any reason it cannot connect try checking user credentials, cables, network adapters, etc.

In today's world setting up a LAN network or internet connection is no longer a daunting task that will require having a bachelor's degree in computer science nor a specialized technician. But even in the present-day environment issues and problems can occur. One of these problems is detecting or running a network at a slower 100MB speed instead of 1GB. Troubleshooting of this nature is somewhat more complex than your typical troubleshooting issue because several things including hardware could be involved in this particular problem but do not worry, we are here to back you up and guide you Setting up a home or small office network no longer requires a specialist technician to constantly monitor and optimize the LAN routers and connected PCs. As Windows networking has improved and new features have become available on the hardware, configuring a 1GB network should be as simple as connecting the LAN to a router that came with this capability. If however the network’s rated speed only gives 100MB, troubleshooting the issue is more complex. To find the problem, you’ll need to check the hardware devices, cable connections, and the software you are using to connect and manage the network.

Hardware checks

1. Check both connection jacks to see if it has any loose or frayed wires. If any of the wires are loose, it can be the cause of the performance issue. You should replace the cable if you discover damage to the connectors.
2. Inspect the entire length of the cable and check if the harness shows any clear signs of damage. A bent or damaged cable can reduce the amount of information it’s capable of transferring between the PC and LAN router. If you find any damage to the cable, replace it to restore your network speed.
3. Is the cable capable of transferring 1GB speeds? Different network cables support different network speeds. A Cat-5 cable will only provide 100MB transfers, while a Cat-5e or Cat-6 can support up to 10GB transfers. Check the cable’s labels to make sure you are using a Cat-5e or higher-rated data cable.

Now when the hardware issue is out of the way we can focus a little more on the software part.

Let's try the first easy solution, run Windows built-in troubleshooter

1. Click the Windows button and type Control Panel. Then select the top result.
2. If your Control Panel shows the Category View, change it to display Small Icons instead.
3. From the list of available applications, select Network and Sharing Center.
4. In your Network and Sharing Center, you can see the active network, set up a new network connection, troubleshoot problems, or change your adapter settings. Before making changes to your device properties, you can let Windows run a troubleshooter on your adapters to see if it can automatically fix your connection issues.
5. Click on Troubleshoot Problems from the Change Your Network Settings section.
6. In the Troubleshooter Application, scroll down and find the Network Adapter option.
7. Click on Run Troubleshooter to let Windows check your network adapter’s configuration for any issues.
8. Select the Ethernet Adapter you’re currently using from the list and click Next to proceed.
9. Wait for the process to complete and check the results. If Windows detects any issues, it will recommend a fix. However, if the configuration of your network adapters does not have any problems, you’ll see a message that Windows couldn’t detect any problems.
10. If there are any issues with the cable, the troubleshooter will detect the connection issue and request you replace the cable and connect it to your PC.
11. It can occur that even after inspecting the cable and you didn’t find any visible damage on the housing or connectors, it could still be faulty. Replace the cable with a new one and rerun the troubleshooter to see if the cable is working as required.

If the troubleshooter finished and you received a Windows Couldn’t Detect Any Issues result, you’ll need to verify your adapter’s speed settings.

1. In your Network and Sharing Center, select the Change Adapter Settings option from the left menu.
2. On the list of adapters, choose the one you’re using and click the Right Mouse Button to open the context menu.
3. Select Properties from the Context Menu to access your adapter’s settings.
4. On the Ethernet Properties window, you can enable or disable different features and install additional protocols. To change the device settings, click on Configure to continue.
5. This will open the Device Controller Properties window where you can check the status, make changes to the settings, find out information about the driver, or check historical events on the device. Select the Advanced tab to access the device settings.
6. On the Advanced tab, locate the Speed and Duplex setting.
7. The Auto-Negotiation option may cause network performance issues on certain Ethernet adapters and routers. The setting allows your adapter to change the speed settings according to the LAN configuration you connect to your PC. If you connect to different LAN networks regularly with different speeds, it can occur that the setting doesn’t update from 100MB to 1GB while switching.
8. Change the Value to match the network speed of the LAN you’re connecting to your PC and use the manual speed setting.
9. Click OK to apply the setting and test your network performance. If your adapter doesn’t have the 1GB setting available but you know the rating should go up to that speed, it could indicate that you aren’t using the right driver for the device.

If you don’t have the setting available or the device still only provides 100MB speeds after changing the Speed setting to a manual value, you may have to update the driver for the device.

1. On the Ethernet Properties Window, once again click on Configure to access the Device Properties Window. Then select the Driver Tab to access your driver details.
2. Select Update Driver from the available options.
3. On the Update Driver window, select the option to let Windows Search Automatically for Updated Driver Software.
4. Windows will connect to the internet and search for the latest drivers online. If a newer driver exists, Windows will download and install the driver for you. If you’re using the latest driver, Windows will inform you that no updated drivers are available.

Although there are several Windows 10 devices that are touchscreen-based, the mouse still remains to be an important part of usage for many users especially the ones who do some hardcore work on their Windows 10 computers or laptops. If you’re one of the users who often edit images or videos either for fun or work, using Touch is difficult as it’s a bit hard to drag on the screen so nothing really beats the mouse. However, as awesome as the mouse is, there are times when you encounter issues while using it. One of these issues is when your mouse pointer lags or freezes so in this post, you can try out a few tips that can help you resolve the issue.

Option 1 – Clean both the mouse and the mousepad

It might sound silly but it is a fact that either the mouse or the mouse pad themselves is the problem. Even though mouse balls are long gone, the laser lights that replaced them are not immune to some dirt which is why you need to clean the bottom of the mouse and then clean the mouse pad afterward.

Option 2 – Try changing the USB port

This is another basic thing you can do to resolve the problem since there are instances when USB ports where either your mouse is connected have gone rogue so you need to try switching to a different port and then see if the problem’s fixed or not.

Option 3 – Switch back to the default settings of the mouse

Switching your mouse back to its default setting is always a good idea since you are dealing with a pointer issue. To go back to the default settings of the mouse, here’s what you have to do:

• Click on Mouse and Touchpad.
• Next, click on Additional Mouse Settings located in the right pane.
• After that, click on the “Use Default” option under the Pointer tab.
• Then click on Apply and OK to save the changes made.

Option 4 – Try disabling Smooth Scrolling

You have to slow down both the horizontal and the vertical scrolling of the mouse in the settings which are called “Smooth scrolling”. This will help if you think that the websites you are visiting scroll up and down way too fast.

Option 5 – Try to update or rollback mouse drivers

If the first few options didn’t work for you, then it’s time to either update or roll back the mouse 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 the mouse driver then you need to roll back the driver. Whichever applies to you, refer to the steps below. The problem may be caused by a corrupted or outdated driver. So you have to update or reinstall the mouse driver. How? Follow these steps:

• Open the Devices Manager from the Win X Menu.
• Then locate the Mouse and other pointing devices and right-click on the mouse driver 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, disconnect the mouse and plug it back in to reinstall the mouse driver.

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 6 – Try to check if your laptop is turning off the mouse

In case you don’t know, the power management can turn off the devices that are not in use to save battery power if you use a laptop. And this can also happen on USB-based devices like the mouse. Thus, you need to verify if your laptop is turning off the mouse.

• Go to Device Manager > Universal serial bus controllers > USB Root Hub > Power Management.
• After opening Power Management, uncheck the “Allow the computer to turn off this device to save power” option.
• If you have lots of USB Root hubs, you can try changing each one of them and see if it works or not.

Option 7 – Try updating the Graphics 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. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC.

Note: You also have the option to go directly to the website of your graphics card manufacturer and check if there’s a new update – if there is, download it.

Option 8 – Try setting the No Delay option for Touchpad

If you are using a laptop that’s touchscreen-based, you can try setting the delay to zero in the settings. To do so, simply go to Settings > Devices > Mouse and Touchpad. From there, you can set the delay before clicks to “No Delay”.

There are times when you may find it hard to kill a particular process in the Windows Task Manager and every time you try to do so, you will only get an error message saying, “Unable to terminate the process, The operation could not be completed, Access is denied”. If you are one of the users who is constantly getting this error, read on as this post will provide you with a couple of options you can try to resolve the problem. Refer to the given instructions below if you are unable to terminate a process in the Task Manager but before you proceed you need to restart your PC and then try killing the process again, if you’re still not able to do it, you need to follow the options laid out below.

Option 1 – Try using Taskkill

• Open the Command Prompt as admin from the WinX Menu.
• After opening Command Prompt, type in the following command and tap Enter to execute it:

taskkill /IM "processname" /T /F processname – it is the name of the process which you can see on the Details tab of the Windows Task Manager. /IM – it is the one that specifies the image name of the process, which follows, that is to be terminated. /T – it is the one that kills not just the main process but also the child process. /F – it is the one that terminates the process forcefully.

Option 2 – Try using the WMIC

• Open Command Prompt as admin from the WinX Menu.
• From the Command Prompt window that opens, type in the following command and hit Enter to execute it:

wmic process where name='processname.exe' delete

Note: In the given command, you need to replace “processname.exe” with the name of the particular process you want to terminate which is found in the Details tab of the Windows Task Manager.

Option 3 – Try using PowerShell

• The first thing you have to do is open an elevated PowerShell prompt.
• From there, type in the following command and hit Enter to execute it:

kill -id pid

Note: In the given command above, “pid” is the Process ID number of the process you want to terminate. And for you to identify this number, you need to open the Details tab of the Windows Task Manager once again and take note of the number against the process you want to get rid of. Alternatively, you can also run the following command in the PowerShell prompt that you’ve pulled up to get the process ID number:

Get-Process

For example, “5364” is the process ID number for the DimScreen.exe process which is the process you want to terminate. In order for you to kill this process, you need to type in this command:

kill -id 5364

If you suddenly find your Windows 10 computer stuck on the “Preparing to configure” screen for quite a long time now after you run Windows Update, read on as you will be guided on how you can fix that issue in this post. During an update process, there’s a lot of things that go on in the background which is why Windows Updates take quite a while before it finishes. It can be at 25%, 50%, or even 100% but the only message you’re going to see on your screen is the “Preparing to configure Windows, Don’t turn off your computer”. However, if you notice that the Windows Update is taking a longer time than it’s supposed to, the first option is to wait some more but if it’s still the same, then there’s definitely something wrong. This kind of issue occurs when Windows Update fails to configure in short correctly download and install the update. When this happens, it will revert all the changes which are why you were advised to wait for a couple of hours. There are two possibilities why your computer is stuck on the “Preparing to configure Windows, Don’t turn off your computer” screen. The first one is that the Windows 10 operating system is installing any updates. The second one is when the user profile takes time to load or encounters an error. There are several options you can try to fix the problem. You can try running System Restore or boot your computer in Safe Mode or repair the corrupted profile via Registry Editor. You might also want to try using installation media to boot and repair your computer if the other options didn’t work.

Option 1 – Perform System Restore

• 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.

Note: If you can’t boot into the desktop of your computer, you can run System Restore in the Advanced Startup Options by following these steps:

• Boot your computer into the Advanced Startup Options screen.
• From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
• Now select Troubleshoot > Advanced Options > Command Prompt.
• After that, type “rstrui” and hit Enter to execute the command which will start the System Restore process.
• Once it’s done, restart your computer.

Option 2 – Boot your computer in Safe Mode

You can try to tap the F8 key if you have it enabled in your Windows 10 computer, as you start your system to boot into Safe Mode. Once your computer is in Safe Mode, you can access the Start Menu and the Mouse and Keyboard. Aside from that, you can also access your files and other built-in tools in Windows such as Command Prompt, PowerShell, Computer Manager, Device Manager, Event Log Viewer, and many more. On the other hand, if you haven’t enabled the F8 key, you can just go to the Advanced Startup options to boot your computer into Safe Mode. Once you’re there, select Troubleshoot > Advanced Options > Startup Settings > Restart > Tap the number 4 key. After that, your computer will restart in Safe Mode. If you want to reboot into Safe Mode with Networking instead, you can tap the number 5 key and for Safe Mode with Command Prompt, tap the number 6 key. Once your computer is in Safe Mode, you can use any of the built-in tools to restore your computer or troubleshoot the problem that’s causing your computer to get stuck at the “Preparing to configure” screen.

Option 3 – Try to repair your corrupted profile via Registry

In this third option, you can try to repair the corrupted profile using the Registry but before you proceed, take note that you can only try this if you can boot into your desktop and if you can, make sure to create a System Restore Point and then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter or click OK to open the Registry Editor.
• Next, go to this registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList
• Once you’ve opened the registry key, you should see a list of all the user profiles on your computer. Now click on each S-1-5 folder and look for the “ProfileImagePath” entry and double click on it to check which user account it is related to. You will see a path like “CUsersACK” where “ACK” is the username.
• You should know which of the user account is corrupted. Just look for a key named “RefCount” and change its Value data to “0” and click OK. And if it isn’t available, simply right-click on the right pane and create it.
• After that, double click on the key named “State” and make sure that the Value data is “0” and click OK.
• Exit the Registry Editor and restart your computer to apply the changes made.

Option 4 – Try to use installation media to boot and repair your computer

Another thing you can try to resolve the issue is to use the Windows installation bootable media so you can boot and repair the operating system. To use it, follow these steps:

• You need to first create an installation media which has the dame version of the operating system installed in your computer.
• After that, once you reach the Install Windows screen, click on the “Repair your computer” link.
• Wait until the repair is completed and then shut down your computer
• Now once your computer has restarted, check if it can now boot properly.

There are times when you install a Windows update to your Windows 10 computer but you only got an error message saying, “The update isn’t applicable to your computer”. This is unusual as Windows was the one that downloaded them in the first place. To understand the reason behind this error, read on as this post will also give you a couple of suggestions you can try to fix the problem. One of the main reasons why this error occurs is that your computer might not have the required installed updates and many more. Other reasons include:

1. The update might be replaced. There are instances when a newer Windows version is already available on the computer and that the version you are trying to manually install is an older version which is why the Windows update failed.
2. The update might already be installed. There are times when the update process is still in progress and the earlier payload might have already been installed.
3. It could also be that it’s a wrong update for architecture. As you know, updates are designed accordingly based on the architecture of the computer so if the update you are trying to install does not match the architecture of your CPU then it’s no wonder you’re getting an error message.
4. Your computer might be missing a prerequisite update. There are Windows updates that depend on other updates so if you missed one and you’re installing another one, it could be the reason why you’re getting the error.

To fix the problem, here are some suggestions that might help.

Option 1 – Try verifying the package and the Processor Architecture

As pointed out earlier, updates are made according to the Windows versions. Thus, if one of the updates failed to install, you need to check if it’s applicable or not. The best way to do that is by searching the Windows update name on the official website of Windows. It could be that the Processor Architecture is not compatible with the Windows Update you are trying to install. If you have an X86-based processor, you can’t install x64-based installations of Windows and vice-versa. This usually happens when you’ve downloaded the update manually and then tried installing it.

Option 2 – Try checking if the update is old

The issue might be because you are trying to install an old Windows update which is why it didn’t work. To check, go to Settings > Update and Security > View Update history. From there, you can look for the update.

Option 3 – Try checking if the update is already installed

To verify the update, just go to the Windows Update history once more as you did in option 2, and then see if the update is already installed or not.

Option 4 – Try checking the prerequisites

AS mentioned earlier, there are some updates that depend on other updates before they get installed on your computer. The best way to verify is by checking the Microsoft Knowledge Base (KB). And to verify if the prerequisite updates are installed or not, just run the command below in PowerShell:

get-hotfix KB1111111, KB2222222, KB3333333

Note: In the command given above, you need to replace “KB1111111, KB2222222, KB3333333” with the actual update KB numbers.

Option 5 – 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.

Hello and welcome to How To Speed Up PC Startup where we will explore how to make your PC boot-up system faster. When your computer gets older, you'll see a decrease in your PC's load time. This can be very annoying and frustrating, especially if you're not accustomed to exercising patience. Your computer's boot time does not need to be sluggish, even if it's old. While there are reasons why your computer is acting up and giving you the 'slow' sign, there are ways that you can optimize how fast your PC starts up at the beginning. Once you start speeding things up, you’ll never look back!

Start With your BIOS

You may need to tweak your PC’s start-up menu. Since the majority of issues encountered on your PC might not be related to the software running in the back end, you can focus on your computer's hardware. The ideal way to speed up your PC startup is to access your computer's BIOS when booting up. This can be accessed by holding the DEL key or whichever button is used to tap into your BIOS. You can change where your computer boots from. You can opt to put your hard disk right at the top which would elude searching for CDs and other storage media devices when your PC starts up.

Tweak Startup Programs

There are many programs that execute when your computer starts up. These programs normally run in the back end. Most times back-end programs are unnecessary and do not contribute to the productivity or performance of your computer when in use. Instead of allowing these programs to execute when your PC boots up, why not disable them?  By deactivating these programs, you'll be reducing the amount of CPU usage which will accelerate your PC performance. Additionally, there are some installed programs that you never use. Instead of leaving these programs to occupy needed space on your computer system, you can uninstall these to create more room on your computer. This actually increases your PC startup speed.

Put Malware on a Leash

Malware and spyware can cause problems for your start-up. A slow computer is an indication that your computer is plagued by malware. This affects your computer's boot time and whether or not it'll startup as quickly as you intend it to. If your computer gives you the 'virus alert', you need to download an antivirus program that will be able to eradicate all virus threats. Be mindful of where you download antivirus programs since many of them are viruses or have viruses attached to them. Some viruses are tough on your computer. This means that if an antivirus works for your best friend, it may not work for you. Since malware differs in functions and the havoc they cause, it's best to know what you're up against by doing research.

Clean Your Registry

You should also clean out your registry. The fewer unused registry keys you have lying around on your computer, the faster your computer will go. Getting a good registry cleaner from a clean source can help tremendously, but be careful; registry cleaners have the potential to be very dangerous so make sure you backup everything on your computer and only download registry cleaners from a reliable source. By implementing the above tips, you'll see quick improvements when using your computer.

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.

Microsoft starting as of today will block its Office 365 users if they are using Internet Explorer or early versions of Edge browsers. So if you are using older non Chromium Edge versions of Microsoft browsers you can no longer access Office services until you switch. Now normally I would fully support this kind of decision since Internet explorer is a slow and vulnerable browser and the edge is similar in that regard. The new edge browser is great and it should be used but the issue I have is that Office 365 is not free, it is a premium feature and I am wondering how Microsoft plans to deal with people that have already paid for service but suddenly cannot access it anymore.
