Fix Windows Update Error 0x80071a91

Privacy is a hot topic lately in all circles so naturally themes like private or incognito browsing pop up immediately as discussion topics. Naturally, when discussing private or incognito browsing it is very important to understand what exactly private or incognito browsing is, what does it do and how it works in order to shed some light on is it really private and safe as we are told. So, when you browse the internet normally websites have tendencies to save your browsing data, save cookies, remember passwords, etc in order to provide you with a better surfing experience next time you visit that same site. Private or incognito browsing treats you as a completely new user which is the first time visiting a given website. It clears all your data, including your browsing history, cookies, etc., on exiting. Every website you visit in private or incognito mode treats you as a new visitor, even if you have visited it before in incognito mode. And basically, that's it. So is it really private? No, it is just a non-remembering mode of internet browsing where after your browsing session history and other data is cleared from the browser, but while you are on the internet you are pretty visible to all like any other normal user. There are a lot of misconceptions and wrong thinking about browsing the internet in this mode so let's take a look at some typical ones.

1. The government and other companies can not track me

   Many people think that the Government cannot trace their identity when they surf privately. This is only a myth. There are many ways by which the Government can reach you if you do something illegal. When you surf online, you are connected with an ISP of your area, which helps the officials track your location.

2. Virus and other malware can not infect me while in private or incognito mode

   Many people think that private mode protects them from virus and malware attacks. It is not true because malware and viruses can enter your PC through a software download, phishing email, etc. To protect your PC from virus and malware attacks, you should have good security software.

3. My IP address is hidden when I am in incognito or private browsing mode

   This is not 100% true. If you search “What is my IP” in incognito and standard mode, you will get the same results. This means that websites can view your IP address in private mode also. Using a VPN would be a good option if you want to hide your IP.

4. I can not be tracked via ads

   Since cookies are deleted after exiting private browsing, many people think that ads cannot track them. When you surf in incognito mode, the browser saves cookies in a temporary mode, allowing ads to track you during your entire private browsing session.

5. I am not visible when I am in incognito or private

   You may think if you sign in to your Gmail or other social media accounts in private mode, no one will see you online. This is not true. It does not matter whether you have signed into your account in normal mode or incognito mode; others can always spot you online.

In your regular browsing mode, you may have some addons, extensions, themes, etc installed and you can use them. They may track your activities. The data is deleted when you exit the browser. When you use the private browsing mode, the browser is loaded in its original form, typically without the installed addons, extension, themes, etc. The data gets deleted when you exit the browser. This mode doesn’t save data to disk but keeps it in memory during the current session. If you are really concerned about your privacy we have articles about using DuckDuckGo and deep web where you can be sure that your browsing sessions are encrypted.

Kernel32.dll Error - What is it?

To understand Kernel32.dll error properly, here’s what you need to know first: in the Windows operating system, the system32 directory plays a vital role. Inside this directory, there is an element called Kernel32.dll. A DLL (dynamic link library) is a library that contains codes and data that are used by more than one program at the same time. The role of the Kernel32.dll file is to handle memory management and I/O (input and output) operations. Malfunctioning of this file results in a Kernel32.dll error message which leads to program or application failure.

Error Causes

Kernel32.dll files can be attributed to several reasons like:

• Missing or damaged Kernel32.dll files
• Registry corruption

If you suddenly encounter Activation Error codes such as 0xC004E016, 0xC004F210, 0xC004F034, and 0xC004F00F on your Windows 10 computer, then they all point to the same issue – Invalid Product Key or Version mismatch. When you see any of the aforementioned error codes above, it indicates that you are either entering a wrong product key or you are using an incorrect ISO when installing it on your computer. In such cases, you may see either of the following error messages:

“You are running Windows 10 Pro, but you have a valid digital license for Windows 10 Home.” Or: “The specified product key is invalid or is unsupported by this version.”

If you got the error code 0xC004F00F then it means that you’ve entered a product key for the Enterprise edition of Windows to activate Windows 10 Pro or Windows 10 Home. It could be that you have a key from your work and you accidentally use it on your Home PC. If you got the error codes 0xC004E016, 0xC004F210, then it means that you have entered a product key that is meant for a different edition or version of Windows. On the other hand, if you got the error code 0xC004F034 instead, then it means that you have entered an invalid product key or a product key for a different Windows version. Whichever error codes you have, refer to the possible solutions given below to fix the Invalid Product Key or Version mismatch Activation Error in Windows 10.

Option 1 – Try running the Windows 10 Activation Troubleshooter

There is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect to your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

Option 3 – Try activating Windows 10 via 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.

A lot of programs in Windows utilize the helper processes to ensure that they can get the job done as early as possible. And one of the programs that use these processes is Microsoft Edge. This built-in browser uses a process called the Edge Content process. The moment you start your computer, these system processes are loaded which makes the Edge browser load faster. To be specific, these are the three processes that are related to Microsoft Edge:

• MicrosoftEdge.exe
• MicrosoftEdgeCP.exe
• MicrosoftEdgeSH.exe

As you know, every Windows Update is essential for every Windows operating system. They have to be regularly installed, especially since they include various security updates that are important to the system. However, there are times when Windows Update fails to execute properly and you get errors like the error code 0x80070BC9. When you encounter this particular Windows Update error, you will get the following error message on your screen:

“0x80070BC9 – ERROR_FAIL_REBOOT_REQUIRED. The requested operation failed. A system reboot is required to roll back changes made.”

This kind of Windows Update error is most likely caused by a newly installed problematic software, corrupted Windows Update files, or policies that restrict the behavior of the Windows Module Installer. The Windows Module Installer, also known as “WMIW” or “TiWorker.exe”, is the one that checks for new updates from the Windows server and installs them on your computer. This is why you need to make sure that you do not have any policies that control the start behavior of the Windows Module Installer since this service must not be hardened to any start value and should be managed by the operating system. To resolve the Windows Update error code 0x80070BC9, you can check out the options provided below.

Option 1 – Try checking the status of the Windows Modules Installer Worker Service

Since the Windows Update error code 0x80070BC9 has something to do with the Windows Module Installer Worker service, you need to check its status in the Service Manager. Refer to the following steps to do so.

• In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “MSC” in the field and hit Enter to open the Services Manager.
• After opening the Services Manager, look for the Windows Modules Installer Worker Service.
• Once you found it, check its status and make sure that its Startup type is set to Manual.
• Now click on the Start button and see if it fixes the Windows Update error.

Option 2 – Run the Windows Update Troubleshooter

You might want to run a built-in Windows Update troubleshooter to resolve the Windows Update error. It is one of the things you can check out as it is known to automatically resolve any Windows Update errors like error code 0x80072EE2. To run this troubleshooter, 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 3 – Try contacting the IT administrator to modify the group policies

You could also try to contact the IT administrator to have the group policies modified. This option is applicable for company-managed systems. As mentioned, one of the possible causes of the Windows Update error 0x80072EE2 is the policies that control the start behavior of the Windows Module Installer. Thus, you need to have them removed so that the Windows Module Installer Worker service is managed by the operating system itself. And since there could be many policies, it is highly advised that you contact your company’s IT administrator to get the job done for you.

Option 4 – Try to install the Windows Updates in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing Windows Update error code 0x80070BC9. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• 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.
