0x8019019a when setting up Yahoo Mail

Well if anyone told me just a few years ago that I will see the day when Microsoft releases a new OS based on Linux I would be very amused, but that day has come. Mariner is the newest OS out of nowhere. Microsoft’s new Linux Distro, dubbed Common Base Linux (CBL)-Mariner, isn’t the type of distro you’d want to install directly on any old machine. It’s primarily meant for cloud infrastructure and edge products. Specifically Microsoft’s Cloud and Edge products. But if you are curious, it’s possible to run. Juan Manuel Rey, a Microsoft Senior Program Manager for Azure VMware, recently published a guide to ISO CBL-Mariner image. With that, you can easily get it up and running. And you can build CBL-Mariner on an Ubuntu 18.04 desktop. So you can try it out since it is free. You can get it from here: https://github.com/microsoft/CBL-Mariner It is obvious that Microsoft aims to set itself as a leader in enterprise server environments with this move and it is very likely that it may succeed or at least give a good shake to its competitors, mainly red hat and Suse which are two dominant distros in that field. Many believe that they can win over by providing regular updates and package delivery via their already established system and that feature could be a turning point for some. In any case, time will tell and we shall see.

Coming in October for insiders and in November for all in the update, Microsoft has prepared a series of updates which they call an "additional set of experiences"

These updates are looked upon by Panos Panay, a vice executive president at Microsoft & chief product officer for Windows and devices as sort of makeup tests. They will consist of new additions with the biggest one being a tabbed version of File Explorer.

File Explorer received a UI makeover in the last update but the tabbed interface was missing which was expected by many users so it will come in following the next update.

The rest of the features that we will receive are an updated Photos application, Suggested Actions in the Windows Shell, Overflow menu for the taskbar, and improved Nearby Share.

The tabbed File Explorer interface is essentially File Explorer’s version of Sets, the tabbed window interface that Microsoft tested out several years ago. In testing, the tabbed interface proved handy for moving and copying files, and we’d expect the same once the feature formally goes live. The difference between Sets and the tabbed File Explorer interface is Sets allowed for multiple applications to be clustered together via tabs.

Photos app will include a “new photos-managing experience that brings a gorgeous gallery, simplifying browsing, finding, management and consumption of your collection of photos.” It will allow “easy backup to OneDrive” and a “delightful Memories experience.”

As for other features, nothing specifically was said except giving just some tips on what will they bring, it is obvious that File Explorer and the photos app were the main focus for MS in this upcoming update.

Upgrading your Windows computer may not always go as expected as you could end up getting some error messages along the way. One of the error messages you can encounter is the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. This error indicates that is some security issue within the Windows operating system. It could be that the system files have an issue and they have been modified incorrectly. Although this does not necessarily mean that malware is behind the modification, one of the applications you installed recently might have something to do with the problem. The application might have modified or corrupted some of the core system files. When you encounter this error, you will see a blue screen along with the following error message:

“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. (0% complete) If you’d like to know more, you can search online later for this error: 0xc000021a”

This error pops up when a user-mode subsystem like the WinLogon or the Client Server Run-Time Subsystem or CSRSS has been compromised fatally and security can no longer be guaranteed in the system. Thus, the operating system switches to kernel mode, and Windows won’t be able to run without the WinLogon or the Client Server Run-Time Subsystem. This is why it’s one of the few cases where the failure of a user-mode service can shut down the system. To resolve the issue, here are some fixes that might help.

Option 1 – Uninstall programs you installed lately

• 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 – Perform System Restore

Performing System Restore can also help you fix the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• 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.

Option 3 – Run the System File Checker or SFC scan

System File Checker or 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 that might be the cause why you’re getting the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. 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 – Rebuild the BCD and fix MBR

Rebuilding the BCD can help you in fixing the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error.

• You can start by booting into the installation environment for Windows 10 from an installation media.
• After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
• Next, select Command Prompt and type in the commands below one by one, and tap Enter right after you do so.
• exe /FixMbr
• exe /FixBoot
  • exe /RebuildBcd

The commands you entered should rebuild the BCD and repair MBR.

Option 5 – Run the CHKDSK utility

You can also run the Chkdsk utility to resolve the problem. 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 commands listed below, and don’t forget to hit Enter right after you type in each one of them.
• chkntfs /t
• chkntfs /t:10

About Browser Hijackers

Browser hijackers (sometimes called hijackware) are a type of malicious software that alters web browser configuration settings without the computer owner’s knowledge or permission. These hijacks appear to be increasing at an worrying rate around the world, and it can be really nefarious and sometimes dangerous too. They’re designed to disrupt browser functions for many different reasons. These are typically used to force visitors to a specific website, manipulating web-traffic to earn ad revenue. Although it might appear naive, all browser hijackers are damaging and therefore always classified as security threats. In a much worst case, your internet browser could be hijacked to download malware that will do a great deal of damage to your computer or laptop.

How one can know whether the browser is hijacked?

Symptoms that a web browser is hi-jacked include: the browser’s homepage is changed; new bookmarks pointing to pornographic sites have been added to your favorite pages; the essential web browser settings are modified and unwanted or insecure sites are added to the trusted websites listing; you are finding new toolbars you have never found before; you might see numerous pop-up ads on your computer screen; your browser has become unstable or starts running sluggishly; Inability to navigate to certain sites, especially antivirus as well as other computer security software websites.

How browser hijacker infects computers

Browser hijackers may use drive-by downloads or file-sharing websites or perhaps an e-mail attachment to reach a targeted PC. They also come from add-on software, also called browser helper objects (BHO), browser extensions, or toolbars. Also, certain freeware and shareware can put the hijacker in your PC through “bundling”. Examples of well-known browser hijackers are Fireball, CoolWebSearch. GoSave, Ask Toolbar, RocketTab, and Babylon Toolbar. The presence of any browser hijacker on your system might substantially diminish the web browsing experience, track your online activities that result in serious privacy concerns, develop system stability problems and eventually cause your computer to slow down or to an almost unusable condition.

How to remove a browser hijacker

Some hijackers can be easily removed by uninstalling the free software they were included with or by removing any extension you’ve recently added to your browser. But, most hijacking codes are certainly not very easy to get rid of manually, as they go much deeper into your operating system.

Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
  • exe /[DLL file]
  • exe [DLL file]

Note: Replace “[DLL file]” with the name of the DLL file that was pointed out in the error.

• After you execute the given commands, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 2 – Replace the DLL file from a trusted source

• First, you need to get the new DLL file from another computer with preferably the same file version number.
• After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
  • x86: This PC > C:/Windows/System32
  • x64: This PC > C:/Windows/SysWOW64
• Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
• Now type the “regsvr32 ntdll.dll” command and hit Enter.
• Restart your PC and check if the error is now fixed.

Option 3 – Perform a System File Checker scan

The System File Checker or SFC scan could detect and automatically repair damaged system files that could be causing the “An attempt was made to reference a token that does not exist” error to pop up. 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 4 – Try reverting back to the previous build of Windows

This kind of error might have something to do with a Feature Update so you can try to revert your computer to a previous build of Windows 10 as it could help you fix the problem. In this case, it would better if you refrain from updating your Windows 10 computer until this problem is completely resolved by Microsoft.
