How to Fix Jp2klib.dll Error Code

If you suddenly find the Windows Recovery Environment not working and you see an error message saying, “Could not find the recovery environment”, then you’ve come to the right place as this post will guide you on how you can fix it. In times when you can’t boot into the Windows Recovery Environment, there could be several reasons behind it. However, have you ever wondered where exactly the Windows Recovery Environment is in your computer? Windows initially places the Windows RE Image file in the installation partition during Windows Setup so if you have installed Windows in the C drive, you can find the Windows RE at the C:/Windows/System32/Recovery or C:/Recovery folder. Keep in mind that this folder is hidden and later on, the system copies the image file into the recovery tools partition to make sure that one can boot into recovery if there are any issues with the drive partition. The “Could not find the recovery environment” error mostly occurs if the Windows Recovery Environment is disabled or if the “Winre.wim” file is corrupted. Thus, to fix this error, you need to refer to the given suggestions below.

Option 1 – Try to enable Windows Recovery Environment

• In the Windows Start Search, type “PowerShell” and from the search results that appear, right-click on Windows PowerShell and then select the “Run as administrator” option to open it with admin privileges.
• Next, type the “reagentc /info” command and tap Enter to execute it.
• After that, if the output states that Status is enabled, then you’re all set.
• Now type the “reagentc /enable” command and tap Enter to enable the Windows Recovery Environment. You will see a success message at the end signifying that Windows RE is available.

Option 2 – Try to fix the corrupted or missing “Winre.wim” file

If the Winre.wim file is either corrupted or missing, you need to get a new copy of this file from another computer where the Windows RE is working. Once you’re able to get a new copy of the Winre.wim file, you have to set the image path to a new location. For more details, refer to these steps:

• First, type “Powershell” in Windows Start Search and right-click on Windows PowerShell from the results, and select Run as administrator.
• Next, execute the given command below to change the path of the WIM file to the new location. Note that the steps should be used when the file path of the Windows Recovery Environment is different from the usual spot.

Reagentc /setreimage /path C:RecoveryWindowsRE

• As mentioned, if the file is corrupted, you just have to get a new copy from another PC but before you do that, make sure that the WINRE on that computer is disabled (just enable it later on) and then place it in the C:/Recovery path and then set its path again using the command given above and then verify its path by executing the following command.

reagentc /info command

Note: Since the Recovery folder is hidden as well as the WINRE folder in it and you won’t be able to access them using the Windows File Explorer, you need to use the Windows PowerShell or Command Prompt so that you can access them.

Option 3 – Try checking and fixing the WinRE Reference in the Windows Boot Loader

The Windows Boot Loader is the one that determines if it has to load the Windows Recovery Environment. It could be that the boot loader is pointing to an incorrect location which is why you’re getting the error. To resolve it, you have to check and fix the WinRE Reference in the boot loader. How? Follow these steps:

• In the Windows Start Search, type “PowerShell” and from the search results that appear, right-click on Windows PowerShell and then select the “Run as administrator” option to open it with admin privileges.
• After that, execute the “bcdedit /enum all” command.
• Next, look for an entry in the Windows Boot Loader identifier set as Current and look for “recoverysequence” in that section and take note of the GUID.
• Ensure that the device and the osdevice items show the path for the Winre.wim file and that they are the same. If not, you need to point the current identifier to the one which has the same.
• Once you’ve found the new GUID, execute this command: bcdedit /set {current} recoverysequence {GUID_which_has_same_path_of_device_and_device}
• Now check if the error in the Recovery Environment is fixed or not.

Option 4 – Try creating a Recovery Media

You could also try creating a Recovery Media to resolve the error in the Windows RE. All you have to do is download the Windows 10 ISO file using the Media Creation tool and then create a recovery drive. Once you’re done, check if it fixes the problem or not.

Hello and welcome everyone, today we will be talking about dreaded keyloggers, why they are dangerous, and how to know if you might have one in your system. Keylogger is a malicious application placed in your system and hidden with only one goal in mind, to get information about what are you typing and by that means for a person who infected you to get information about your credit card information or other sensitive data. They can be introduced into your systems in various ways and often can not be detected easily. Modern antivirus applications have ways of detecting them and removing but this tutorial aims to teach you how to spot them all by yourself since new keyloggers are produced daily and sometimes relying on antivirus alone is not enough. Unlike viruses and trojans, keyloggers are not heavy on system resources and you will not feel slow down on your computer if you have one which makes them harder to sport with regular work. Some of them can be even tracking you on the website and not even be physically present on your computer. Generally, we could categorize keylogger into 4 categories:

1. Web browser-based keylogger. Some websites would have CSS scripts, input web forms, or so-called man in the middle keylogger. Lucky for us even Windows defenders with the latest update can detect this type of keylogger and successfully deal with it and how keylogger itself is not present on our system we are safe.
2. General spyware keylogger. This keylogger is present in your system, usually, it infected it via email attachment, social media download, torrent download, some malicious so-called fixer application, etc. Most antivirus applications and windows defenders can detect these types as well and remove them successfully.
3. Kernel-level keylogger. This keylogger is a more dangerous type they tend to operate underneath Windows as a rootkit and can go undetected by antivirus and windows defenders.
4. Hypervisor-based keylogger. This is the most dangerous keylogger, they use virtualization techniques to hide and mask themselves as a replica of the operating system and they scan all keystrokes by the user. These are very rare keyloggers but they do exist.

If you suspect that you have a keylogger or just want to check your system for precaution reasons follow these tips and guides and luckily you will solve your issue in no time and your data will be safe.

1. Use Task Manager to find suspicious entries.

   Task manager is a great application implemented in Windows that is constantly monitoring and showing all services, applications, and processes currently running on your system and thus a great tool to monitor your system if you know how to use it. First, open task manager by pressing CTRL + SHIFT + ESC Then take a good look into it, try to find suspicious names, probably duplicate of running application, something like Windows logon application, or keylog or anything similar which seems out of ordinary. If you manage to find a suspicious running application right-click on it and close it. Also while you are in task manager jump into the startup tab and check to see are there some unusual applications starting with your Windows, if you find anything, disable it right away. This is the most simple and quickest way to get some information right away if you suspect to have some simpler keylogger in your system.

2. Use the command prompt to monitor your network.

   In order to check connections to your computer and find potential suspicious ones start the command prompt in administrator mode, press ⊞ Win + X, and choose command prompt (administrator). type in netstat -b and press ENTER. All website and application connections to your computer are now visible. ignore svchost, edge browser, windows store, etc ad check the IP of the remaining ones using the internet.

3. Use keystroke encryption.

   Install encrypting software and even if you have a keylogger, the application will encrypt each stroke and all that attacker will get is gibberish

Please remember to always download files from trusted sources, do not open unknown emails, and do not share your information publicly. Take common protection steps in order to protect yourself in the digital world.

A copy of Windows gets into a grace period when it is installed on a computer which means that you can use your Windows computer without any constraints on its feature. However, if you suddenly encounter an error code 0xC004F009 then this means that the grace period has already expired. In such cases, you will see the following error message on your screen:

“Error Code 0xC004F009, The Software Licensing Service reported that the grace period expired.”

One of the possible causes of this error is that it could be that the grace period has already expired way before the system was activated which is a result of which the system is in the Notifications state at this moment. The error code 0xC004F009 has something to do with MAK-enabled computers in an enterprise when it comes to Volume Licensing. One of the reasons that this error pops up is due to the possibility that the computer was not activated yet even when it was already connected to the Enterprise. Another most likely cause of the error is when the system was never connected with the Enterprise at all and the given grace period has expired before your computer system is activated. Whatever the real cause of this error, this post will guide you in fixing it. Just refer to the instructions given below to fix it.

Option 1 – Try activating Windows using the command-line tool

• First, you need to obtain your MAK key from the IT administrator.
• Once you have it, tap the Win + R keys on your keyboard and then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
• After that, type this command and hit Enter to install the product key or replace the existing one: Slmgr.vbs –ipk <your mak key>
• Next, type another command and hit Enter: slmgr.vbs –ato
• Once you’ve executed the given commands, Windows should be activated after it connects to Microsoft servers and then gives it some time and try to check if error code 0xC004F009 is now fixed or not.

Option 2 – Try activating Windows using your mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

Option 3 – Try to prolong the grace period

On the other hand, it is also possible for you to prolong the grace period but you might have to get another genuine Windows key for that. Before you proceed, you need to create a System Restore point first afterwards, refer to the steps given below to increase the grace period of the Software Licensing Service on your Windows 10 computer.

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field then hit Enter to open the Registry Editor.
• After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionSetupOOBEmediabootinstall
• Next, change the value of the “mediabootinstall” key to “0”.
• Now open Command Prompt with admin privileges and then type this command and hit Enter: slmgr –rearm
• The command you just entered will add another grace period to your system activation. After that, you have to obtain a new key and then activate Windows.

Option 4 – Try running the Windows 10 Activation Troubleshooter

You can also try to run the Windows 10 Activation troubleshooter to help resolve the error code 0xC004F009.

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

Next-generation of RAM, DDR5 supposed to hit shelves around late summer or fall in 2021if everything goes as planned. Its goal is to increase speed and efficiency, wants to pack more memory in a single stick, and have better power management.

Hardware requirements for DDR5

Using the latest memory technology will require other hardware to follow certain standards and the first ones that will need to follow are CPUs and Motherboards. Intel is already prepared with its Alder Lake CPUs that suppose to come out also later this year. AMD on other hand has not stated anything at the time of this writing but it is a bet that their next generation that will come in 2022 will have full support. It is speculated that bot companies and their respective CPUs will have both support for DDR4 and DDR5. A story about motherboards is a little different. Motherboards will support DDR4 or DDR5 memory banks, not both, so make sure that your motherboard will support the memory you plan on getting.

Capacity of memory

The goal and aim for the DDR5 memory stick are to reach a whopping 126GB per stack. This will be done by using a dual in-line module or DIMM enabling larger capacity. That being said, the first modules that we will see are more likely to be 16GB as standard and 8GB as low entry ones.

Power consumption of DDR5 memory

The standard voltage that DDR4 operates under is 1.2V. DDR5 wants to lower this to 1.1V without sacrificing speed. Voltage regulation on modules themselves will be now integrated on memory banks instead of leaving that to motherboards which will help to detect memory errors directly on the memory bank.

Speed of memory

The most common speed of DD4 memory banks is 2,666MHz, more expansive ones go from 3,600 to 4,000MHz. DD5 aims to raise this bar to 4,800MHz and offers greater speed.

Should you get it right away?

Hardware is ever-evolving, we have PCIe 3.0 to PCIe 4.0, and taking into account that sometimes the newest tech can cause some unexpected behavior it is always the best strategy to wait for a little. Price for the newest tech has also been in its heist just when it is released and seeing how DDR5 will benefit mostly servers mostly since even today memory, processors, and other available equipment can tackle all daily tasks.

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. 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.
• After opening the Device Manager, locate the device drivers that are marked with a small yellow exclamation mark icon and right-click on each one to open their Properties. On the other hand, you can also look for sub-entries under Sound, video, and game controllers like the C-Media USB Audio Class
• 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.

Windows 11 comes with glass and transparency effects by default once it is installed. The transparency effect looks really good but if in any case, you do not like them, you can easily turn them off very easily

1. Open settings inside Windows 11
2. Inside settings click on Accessibility in the sidebar
3. Click on Visual Effects on far-right
4. Inside Visual effects, settings click on the switch beside Transparency effects to OFF

Windows will automatically save settings and apply changes right away. Just close your settings application and continue with work. You can always turn it back ON if you change your mind.

If you have multiple keyboards, things can get quite tricky. There are times when the keyboard language changes on its own since the keyboard changes while you are typing. The thing is, the keyboard changes because sometimes we accidentally tap shortcuts like Win key + Space key or Alt + Shift or Ctrl + Shift which changes the keyboard pairs or language. Thus, if your keyboard language changes on its own, there are two ways to resolve it. First, you have to make sure that Windows 10 does not add keyboards without your permission. Second, you have to make sure that the shortcut keys don’t change the keyboard language. This second option is what we’re going to discuss in this post. You need to first set a different input method for each app window. To do that, you have to disable the change in layout. Refer to these steps:

• Go to Settings > Language and input.
• Next, type “switching input methods” to open the Advanced keyboard settings with this option inside.
• After that, select the checkbox labeled as “Let me set a different input method for each app window” and then click the Save button.
• Restart your computer.

Now that you’ve disabled the change in layout, you now have to find the keyboard settings. Just go to Settings > Devices > Typing > Advanced Keyboard settings. From there, you have the option to select which keyboard is going to be used for any app. When you change the keyboard every time you use an app, usually, Windows remember it so that you won’t have to set it up all over again. In addition, the Advanced keyboard settings page also allows you to override the default input method which could be different from the first one in your language list. Aside from that, there is also a Language bar option that comes in handy as you can quickly switch between keyboards. And if you removed it, you have the option to restore the language bar back as well. Now all that’s left for you to do is to change the Language Settings under the Administrative tab. A user from a forum that came up with this solution, reported that the issue occurred when he started typing in some program with non-Unicode characters which caused Windows to use the default system local language to interpret these characters even though the language is unavailable in the Language bar. To change the Language Settings under the Administrative tab, follow these steps:

• Go to Settings > Time and Language > Language > Administrative language settings.
• After that, click on Copy Settings under the Administrative tab.
• Now make sure that all the Display language, Input language, and Format are English (United States) or any language you prefer.
• Then mark the two checkboxes in “Copy your current settings to Welcome screen and system accounts & New user accounts”.
• After that, click OK and then exit.

Note: You also have the option to disable those shortcut combinations which can change your keyboard settings accidentally.

A lot of things can go wrong even when you’re only doing some simple operations or tasks on your computer and this is due to the fact that there are various small operations make up in order to perform the larger operations on your computer. So if any of these smaller operations are not properly working, it crashes the operation as a whole and it throws an error code instead. And one of these error codes is Error 0x800701e3. This particular error pops up when an error has occurred in the File Explorer when a transfer is initiated from one disk to another in your Windows 10 computer. When you encounter this error, you will get the following error message:

“Error 0x800701e3: The request failed due to a fatal hardware error.”

There are several methods you can check out to fix this error – you can try to run System Restore or Check Disk or format the destination drive or check the SMART attribute of the drive. For more details, refer to each one of the following options.

Option 1 – Try to run System Restore

Error 0x800701e3 might be due to some adjustments you’ve made in your computer’s settings. Thus, to fix this error, you can try undoing those changes using System Restore. How? Refer to these steps:

• 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 then check if your mouse is now back to its normal state.

Option 2 – Try running the Check Disk utility

You can also run the Check Disk utility in fixing Error 0x800701e3.

• In the Windows Search box, type “command prompt” and from the search results, right-click on Command Prompt and select “Run as administrator”.
• After opening Command Prompt, type this command and tap Enter: chkdsk <Partition Letter>: /f /r /x /b
• The command you entered will start to check for errors and fix them automatically. Else, it will throw an error message saying, “Chkdsk cannot run because the volume is in use by another process. Would you like the schedule this volume to be checked the next time the system restarts? (Y/N)”.
• Tap the Y key to schedule Disk Check the next time your computer restarts.

Option 3 – Try to format the destination drive

Formatting the destination drive could also help you resolve error 0x800701e3. To format your drive, follow these steps:

• First, open File Explorer and then right-click on the drive where you encountered the error.
• Next, select Format from the context menu. This will open a new mini window.
• Then select the NTFS option from the drop-down menu for the File System menu.
• After that, check the box labeled as Quick Format.
• Now click on Start. Keep in mind that doing so will remove all the contents of your storage device.

Option 4 – Verify the hard drive using SMART attributes

In case you don’t know, Windows has a built-in feature of SMART analysis which analyzes the hard drive/SSD and checks all the parameters by performing some minor operations. To use it, follow these steps:

• Tap the Win + S keys and type “command prompt” in the field then right-click on the related search result and select the “Run as administrator” option.
• After opening Command Prompt as admin, type the “wmic diskdrive get status” command and hit Enter.
• You should get a result after that, and if you see that it’s “normal”, proceed to the next option below

There are times when you encounter some issues while your Windows 10 computer. One of the errors you can encounter in the update process is the “Something went wrong, error code 0x8007042B”. This kind of error might be caused by several reasons and it could also pop up in lots of cases like upgrading to a new feature update or a new build using the Media Creation tool or Windows Update Assistant. There are times when the Windows Update error code 0x8007042B is followed by another error code like 0x2000d. Whatever the extra error code that follows, the core issue still remains the same. To resolve the problem, here are some options that could help. And while going over these troubleshooting tips, you have to keep clicking the Update button right after you carry out a troubleshooting option.

Option 1 – Try to restart the Background Intelligent Transfer Service

The Background Intelligent Transfer Service or BITS is a part of the Windows Update service and is the one that manages the background download of Windows Update, as well as scans for new updates and so on. And if Windows Update is experiencing some problems, you can try restarting BITS but make sure that you have admin privileges to do so.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter to open Windows Services.
• From the list of Services, look for the Background Intelligent Transfer Service and double-click on it to open Properties.
• After that, you need to set the Startup type to “Automatic (Delayed Start) and click on Apply.
• Now click the Stop button to stop BITS and then click the Start button to restart the service.
• Click OK to save the changes made and then restart your PC.

Option 2 – Try creating Windows 10 ISO media

In this option, you will have to create a Windows 10 bootable media and use it to install the latest Windows 10 version. The most user reported that this option works and the reason why it does have something to do with the Windows Update client since the Windows Updates downloaded from the regular Windows Update client seems to create issues such as the Windows Update error code 0x8007042B. However, issues like this one don’t occur when the very same Windows Updates are downloaded and installed via an ISO file. Take note that when using a Windows ISO file, you will be asked to choose what you want to do with the previous settings and apps. A lot of users opted for the “Not to keep the old Windows settings” option which has resolved the issue. So if you want to keep the previous settings then you must try to update Windows first while keeping the old settings. However, if it doesn’t work, you have to try installing the latest version of Windows without keeping the previous settings.

• Click this link and then click the Download Tool Now button.
• Next, click the “Use the tool to create installation media (USB flash drive, DVD, or ISO file)…” option and follow the next given instructions on the screen.
• Now select the ISO file option in step 5.
• After that, you should now have an ISO file.
• Next, go to the location where you’ve downloaded the ISO file.
• Then right-click on the Windows 10 ISO file and select the Open with option and then select File Explorer.
• Now click on “setup.exe” and follow the next instructions that appear on the screen. When asked, you have to select either the Nothing (clean install) or the Keep personal files only option. Take note that you must not select the “Keep personal files, apps, and Windows settings since it doesn’t really work.

Option 3 – Run the DISM tool

You can run the DISM tool as well to help fix the error code 0x8007042B during Windows Update. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 4 – Perform a System File Checker scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Windows Update Error 0x8007042B 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 with 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.

Option 5 – Run the Windows Update Troubleshooter

You might also want to run the Windows Update Troubleshooter as it could also help in fixing Windows Update Error 0x8007042B. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 6 – Contact Microsoft Support for assistance

If you notice that your tabs in your Firefox browser keep on crashing recently, then there might be something wrong with your browser. Every time any of your tabs crashes, you might encounter an error message saying, “Gah, Your tab just crashed”. If you encounter this kind of error message then it is most likely that your Firefox Profile is having some issues with the existing installation of Firefox. The “Gah, Your tab just crashed” error rarely happens but when it does, it can get quite annoying as you won’t get to browse the internet peacefully. So to fix it, here are some suggestions you could check out.

Option 1 – Try disabling multi-process tabs in Firefox

Since Mozilla has one process for Firefox itself, while one process handles all the tabs, you have the option to disable these multi-process tabs in Firefox. To do that, follow these steps:

• In the address bar of Firefox, type “about: config” and hit Enter.
• Next, look for the following configurations and set them to false.
  • tabs.remote.autostart = false
  • tabs.remote.autostart.2 = false
• After that, double-click on the toggle switch between true and false.

Option 2 – Try checking your Add-ons

In this option, you need to start Firefox in Safe Mode and then check if the problem is fixed. If it is, you may have to check your Firefox add-ons as well as extensions as one of them might be the one that's causing the “Gah, Your tab just crashed” error.

Option 3 – Downgrade the Firefox version you’re using

It could be that the current version of Firefox you’re using has some issues so you might have to downgrade it, especially if you are already using the latest version. To downgrade your Firefox browser, go to the directory of the other versions and languages and select an older version that worked for you. After that, you have to disable automatic Firefox updates.

• First, click the menu button and select Preferences.
• Next, go to the Firefox Updates section under the General panel.
• Then select the radio button labeled “Check for updates but let you choose to install them”. This will ensure that you will not have the same issue with the new update.

Note that this is only a temporary fix since updating your programs, including browsers.

Option 4 – Try sending Crash Reports

You might want to send crash reports to Mozilla. This way, Mozilla might come up with some fix to resolve the problem. All you have to do is type “about: crashes” in the address bar. This will list all the crash reports. Now send it to Mozilla using the built-in interface. Although this won’t instantly fix the problem, a lot of user finds it useful. And besides, the issue will get fixed in future releases or with minor updates.
