Fix Error Code 0x80090016 for PIN and MS Store

This post will guide you in fixing high CPU, Memory, and Disk usage problems caused by NTOSKRNL.exe. NTOSKRNL stands for “NT Operating System Kernel. This file is a kernel image that is responsible for a lot of systems-based processes such as Hardware Virtualization, Process, and Memory. Aside from that, it is also the one that compresses the old pages of memory that reduces the overall amount of memory being used. If you notice that your computer is running slowly and you find that the NTOSKRNL.exe file is hogging your resources such as disk usage, CPU usage as well as memory usage, then read on as this post will guide you in fixing the problem caused by NTOSKRNL.exe. Make use of the options given below to resolve the issues caused by NTOSKRNL.exe. 1] Scan your computer for potential malware There might be a good chance that your computer might be infected with malware. And this malware might be associated with the NTOSKRNL.exe file and hence making it consume a lot of system resources. So, I would really recommend you to make sure that your Antivirus is up to date and then scan your computer with it specifically the C:/Windows/System32 folder because this is the location where the NTOSKRNL.exe file is located.

Option 1 – Put your computer in a Clean Boot State

The first thing you have to do is to put your computer in a Clean Boot State as this can help you in finding any incompatible programs that are causing the problem.

• 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” check box 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.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Once you’ve found any incompatible programs, you need to uninstall them. Refer to the steps below to do so.

• 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.

Option 2 – Update or rollback drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 3 – Try to run the DISM tool

If the first two options didn’t work, then running the Deployment Imaging and Servicing Management might. 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 – Try to stop the Runtime Broker process

The RuntimeBroker.exe or the Runtime Broker process is the one that monitors access to Windows APIs to make sure that the apps do not violate the core security of Windows. This process usually leaves a very small footprint. However, there are times when it consumes more resources than it’s supposed to and does not release memory after the work is done that results in a memory leak. As a result, it affects NTOSKRNL.exe which is why you have to stop the Runtime Broker process. To do so, refer to these steps:

• Tap the Ctrl + Shift + Esc to open the Task Manager.
• After opening Task Manager, go to the Processes tab and look for the Runtime Broker process.
• Once you find it, check if it is using more than 15% of your memory. If it is, then you most likely have an issue with an app installed on your computer.
• Select the Runtime Broker process and right-click on it and then click on the End Task option to end its process.

Option 5 – Try to run the Performance Troubleshooter

• Tap the Win + R keys to open the Run dialog box.
• Type “msdt.exe /id PerformanceDiagnostic” in the field and hit Enter to open the Performance troubleshooter.
• Then click on Next to get started. Wait until the process is completed.

Option 6 – Try using the Windows Performance Toolkit

You can also use the Windows Performance Toolkit in finding the root cause of the problem. Just refer to the following steps to use this toolkit.

• Search for “cmd” in the Cortana Search box and click on Command Prompt from the search results to open it.
• Next, type in the command given below or copy and paste it and then hit Enter:

xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 256 -FileMode Circular && timeout -1 && xperf -d cpuusage.etl

• After executing the command, wait for at least 60 seconds and then check the logs of the Windows Performance toolkit which is stored in a file named cpuusage.etl in the folder located at C:/Windows/System32. From there, you should see a list of all the causes of the System Resources being hogged.

AtoZManuals is a Browser Extension developed by MindSpark Inc. This extension offers users an easy way to search Customer Manuals for Products. This extension may seem handy at first, however, this extension hijacks your browser home page, and changes your default search engine to MyWay.

While browsing the internet with this extension you will see additional ads, sponsored links, and pop-up ads in your browser. Additionally, this extension monitors your browser activity, including search words, visited links, shopping information, and sometimes even personal information, which is later used to display better-targeted ads.

Multiple anti-virus scanners have marked this extension as a Browser Hijacker, and due to its rogue behavior, it is not recommended to keep it on your computer.

About Browser Hijackers

Browser hijacking means a malicious program code has control over and altered the settings of your browser, without your permission. They’re made to interfere with web browser functions for various reasons. Often, it’ll drive users to predetermined websites that are trying to boost their ad earnings. Although it may seem naive, these tools were created by vicious people who always look to take advantage of you, so that hackers could earn money from your naivety and distraction. When the program attacks your laptop or computer, it begins to mess things up a whole lot that slows your system down to a crawl. In the worst-case scenario, you may be forced to tackle serious malware threats as well.

How one can recognize a browser hijack

There are various signs that indicate the internet browser has been hijacked: your homepage is reset to some unfamiliar website; you observe new unwanted favorites or bookmarks added, typically directed to ad-filled or porn sites; default search engine is changed; you see many toolbars on the browser; your internet browser displays endless pop-up windows; your browser has become unstable or starts running sluggishly; you’re prohibited access to specific web pages, for example, the site of an antivirus software developer like SafeBytes.

How it infects your PC

A browser hijacker could be installed on your PC when you check out an infected website, click on an email attachment, or download something from a file-sharing website. They are generally included with toolbars, add-ons, BHO, plug-ins, or browser extensions. A browser hijacker could also be installed as a part of freeware, shareware, demoware, and fake programs. Examples of popular browser hijackers are Fireball, CoolWebSearch. GoSave, Ask Toolbar, RocketTab, and Babylon Toolbar.

Getting rid of browser hijackers

Some kinds of browser hijackers can be removed from the computer by deleting malicious software or any other recently added freeware. However, many hijackers are much more difficult to discover or remove since they could get themselves connected with some important computer files that enable it to operate as a necessary operating-system process. Furthermore, manual removals demand in-depth system knowledge and thus could be a very difficult task for novice computer users.

If you connected headphones to your Windows 10 computer to listen to audio but when you check it in the playback devices, you’re not able to find it, read on as this post will guide you in what you can do to figure out what exactly caused this kind of problem and how you can resolve it. This kind of issue could simply be with the headphone itself or the headphone port or your operating system. So if it turns out that the problem is with the hardware, you might have to replace the components. However, it is recommended that you troubleshoot the problem first before doing that. The most basic thing you can do is to try changing the headphone port, although this can be quite difficult since most computers don’t have any extra port for headphones if your computer has one, then give it a go. If it still didn’t work, follow each one of the options provided below.

Option 1 – Try to run the Playing Audio troubleshooter

Since the Windows 10 operating system has the Playing Audio Troubleshooter, you can use this troubleshooter to try and fix the problem with the “No Audio Output Device is installed” error. You can access this tool in the Control Panel or in the Taskbar Search and even on the Troubleshooters page of Windows 10. Run this troubleshooter and see if it can fix the issue or not.

Option 2 – Try to update the Audio driver

If the error has something to do with software, chances are it might be related to the audio driver – it could be that the newest version of your Windows 10 does not work well with the old version of the driver. This is why you have to update your audio driver to the newest available version.

• Tap the Win + R keys to open the Run dialog box and then type in MSC and tap Enter or click OK to open the Device Manager.
• Expand the section of the Audio inputs and outputs.
• And then from the drop-down menu, select the Update Driver option and follow the on-screen instructions to install the latest version of the driver.
• Then also click on the option, “Search automatically for updated driver software.
• Restart your PC after the installation.

Note: If updating the Audio driver didn’t work, you can go to the website of your PC manufacturer and look for the support section where you can download the drivers for your computer. You just need to take note of your PC’s correct model and model number so you can find the appropriate driver.

Option 3 – Try enabling the headphones from the playback devices

• Tap the Win + R keys to open the Run dialog box and type the “CPL” command.
• Tap Enter to open the Playback devices.
• Next, right-click on any open space section and check the boxes for the “Show Disconnected Devices” and “Show Disabled Devices” options.
• After that, this should help in displaying the headphones in the section of Playback devices.
• And if they are disabled, you can just right-click them to have them enabled.

Hello and welcome to our Business Email Etiquette. Most people have experience in writing emails at some point before in their lives. However, the emails an average person writes are probably personal emails and not mails for work purposes. Emails you send to friends are incredibly different in content and context to business emails you would send to customers or employers or even other colleagues in your workforce. So, if you have a job that involves you writing emails to people in business style, learning business email etiquette is an absolute must for you.

 1. Heading layouts

When you are sending emails to friends, you generally lay them out like a memo. This means there is very little detail in the layout besides basic greetings and paragraphs, usually starting with the greetings. However, with a business email, it is best to lay it out exactly like you would lay out a formal letter. You need to put the company’s address in the right-hand corner and the date as well. Only then must you go on to the greetings. This will make your email look more formal, making you seem like a professional who knows what they are doing as opposed to someone who just couldn’t be bothered spending the extra time to get the layout right.

 2. Proper greetings

 When you are sending an email to a friend, you usually greet them informally. If their name was Mary Johnson, you’d probably start your letter with a ‘Hey Mary’ or a ‘Hello Mary.’ However, this is not considered a professional way to write an email to a customer or other important person in your business. Again, you must use the proper method that you would greet someone with were you writing them a formal letter instead. If your customer is Mary Johnson again, you should greet her with respect. ‘Dear Ms. Johnson’ would be the most appropriate way to start off your letter’s actual body in this case. If you do not know the recipient’s name, then you should start with a simple ‘Dear Sir or Madam.’ Politeness will always get you incredibly far, no matter what line of work you are in.

 3. Informal language

 You should get straight to the point with your email. Don’t dawdle on with it like you would if chatting to a friend and don’t write it how you would speak either. You use language that sounds impressive and smart while not using such obscure language that your recipient doesn’t know what you are saying. All the time, you must keep it informal where possible, possibly even impersonal as well. It will make you seem very professional in the long run.

 4. Signing off

When you are sending your email, you must end it as you would with a letter also. Don’t just say ‘Bye’ and your first name; that is too personal. You need to say ‘yours sincerely if you know the name of the recipient and ‘yours faithfully’ if you do not. Then you should end with your full name and whatever position you have at the company. (CEO, technical staff etc.) So there you have it! All you need to do now is to show your boss that you can handle the emails from now on!

TCI/IP or as known as Internet protocol is one that controls packets that are sent over the internet and makes sure that each one has reached its destination so you can pleasantly browse your favorite websites. The setting for the given protocol is stored locally on your machine and most of the time, everything works fine and good, but sometimes, these settings can get corrupted.

Malware or other software can temper with setting making TCP/IP making it wrong and throwing nondescript connection errors in your face. If you are faced with this issue worry not because fixing this issue is really easy.

Before we actually go and fix the issue please do scan your system with your protection suite just to be sure that if there is any kind of malware on the system it is properly removed from it.

Resetting TCP/IP

First thing is to open search and find PowerShell, press the Windows key on the keyboard, and type in PowerShell so search results are shown. Click on Run as administrator to open PowerShell in elevated mode.

Once PowerShell is opened type indie it:

netsh IP reset and press ENTER. The task will start executing and at this point you will see a lot of Resetting, OK! messages. Once everything is finished restart your PC and you are good to go.

When clean Windows is installed or when you place new hardware in your computer usually Windows itself detects the device and installs its driver. The question that comes now is, do you keep that driver or do you install the manufacturer's one. In order to answer this question let's analyze what is difference between the two drivers and other factors which could influence your decision.

Difference between drivers

First of all, know that drivers Windows installs are also drivers from the device manufacturer which have gone through Microsoft quality control in order to be included in Windows itself. Now naturally question which occurs, what is the difference, well answer to that would be this: in Windows, you have stripped down driver, just a driver in order for Windows to know what device is plugged and how to use it, meaning that for example if you install printer device, you will be able to print documents and Windows will know it is a printer but ... You will not get the control panel for that printer where you can adjust the printer itself and all of its features like let's say paperweight, etc. So if you need these kinds of features in that case it would be better to install a complete driver suite from the manufacturer and get the whole package. Windows will recognize the RAZER mouse for example but you will not be able to change its colors of program custom buttons on it until you install RAZER drivers. One more important thing to note is that drivers which are in Windows are less updated than drivers from the manufacturer's site. That being said, if you prefer and want to have the latest drivers you will prefer to get them again from the manufacturer.

Conclusion

So it seems that manufacturer's drivers are always in some form of advantage and that you will always want them and most of the time this is true, as a matter of fact, the only time I could think that you could use bare down Windows drivers is when new drivers update breaks something in Windows and device start behaving improperly. in this particular case, it is better to roll back to the previous Windows driver which has passed Microsoft quality control and is working for sure. In any other case, you are better off with the latest manufacturers drivers If you would like to read more helpful articles and tips about various software and hardware visit errortools.com daily.

DLL files have certain functions that help the programs in the computer run properly. One of these DLL files is the Msvcr120.dll_clr0400.dll. This particular DLL file is responsible for the extraction of the required resources during the installation of a program and is used when the program is launched or when games are launched in the C++ language. However, a number of users recently reported that they’ve encountered an error that says, “Msvcr120.dll_clr0400.dll is missing” when they tried to install an application or when they tried opening an application. This kind of error could be due to several factors. It is possible that the DLL file is corrupted or there are some programs that interfere with the DLL file. On the other hand, it is also possible that it has been infected by a virus. To resolve this error, here are some potential fixes you need to check out:

Option 1 – Run System File Checker scan

The first thing you can do to fix the error is to try running the System File Checker or SFC scan. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

• Hit the Win + R keys 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.

• Reboot your computer.

Option 2 – Troubleshoot the missing Msvcr120.dll_clr0400.dll error in a Clean Boot State

You can also troubleshoot the isDone.dll error in a Clean Boot state. It could be that there are some third-party applications in your computer that are preventing the application from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• 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” check box 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.)
