How to Fix 0x80070643 Error Code

Error 550 - What is it?

Error 550 is an SMTP (Simple Mail Transfer Protocol) outgoing server error code. It usually occurs when you try to send emails through your Outlook account and the email message encounters a relay error. The email returns back without being delivered with a 550 error message. The error message is prompted as either of the following:

"550 Requested action not taken: mailbox unavailable" "550 5 2 1 mail from refused spam site"

In other words, the error code 550 means that your SMTP server was not able to deliver the sent email to the user.

Solution

Error Causes

There are multiple reasons for this error message including:

• The email address was typed incorrectly
• Incorrect SMTP Server settings
• ISP placing restrictions for outgoing mails on the email server
• System infected by virus or malware

Further Information and Manual Repair Regardless of what the reason may be for the error 550 code occurrence, it is advisable to repair and fix the issue quickly to avoid inconvenience. You may not be able to send emails from your Outlook account if the error continues. This can cause great hassle in corresponding with others timely and may create a big communication gap. Here are some quick and efficient ways to resolve this issue on your system:

Solution 1:

There is no need to panic when you encounter error 550. Sometimes the error message may occur because you inserted the wrong/ incorrect email address of the recipient. In such a case, cross-check the recipient’s email address to verify if it is correct. If not, insert the correct address and try sending the email again.

Solution 2:

If the error still persists, try other methods to resolve it. Sometimes error 550 can also occur due to incorrect SMTP settings. Fix it to resolve the error. This can be done by opening your Outlook settings Tools and Accounts option. Now go to view/change the email account for the email account you are having problems with. After that check, the SMTP server is set to mail.yourdomain.com. Then click more settings and then click the outgoing server tab. See if the ‘My server requires authentication for the outgoing server’ is checked. If not, then check on it. Then simply save to confirm changes. Now try emailing again. Hopefully, this will resolve the issue.

Solution 3:

Another reason for the error occurrence can be ISP blockage. When the junk email volumes increase, network administrators (the people who are responsible for managing ISP servers) place restrictions on SMTP email servers to prevent spam on their network. If this is the reason, contact your ISP administrator to resolve the issue.

LINUX has become more than just a dedicated server Operating system, more and more it is gaining ground in home computers as well and as services like Steam and Gog are offering their titles for LINUX it is gaining more and more ground daily.

Why LINUX?

So, what makes LINUX so good? First of all security, no other Operating system has that high level of security like LINUX and that is the reason why it is widely used as a server. Other advantages are it is less resource hungry and its architecture is made in such a way that it does not has applications remains and traces which remain in the system, once an application is deleted from OS, it is deleted and every trace is removed from OS. Apple OS is based on LINUX kernel but made specifically for their hardware.

LINUX popularity

So naturally, the question pops up why LINUX is not more popular? One of the reasons is its difficulty, to work in LINUX you need to have some level of computer knowledge, Windows is more user-friendly and a lot of people prefer the ease of use to features. This is somewhat been fixed sort of speak in last years since we have LINUX distributions which aim to be more simple and user friendly but it is far from easy of use of one Windows. Another big reason was software support. Altho some powerhouse software has its LINUX versions and works just fine, even better than on Windows, your typical user applications lack and games were almost non-existent making LINU users rely on Windows emulation software for simple applications, and often it did not work properly. This has also changed for the better in later years but as with the previous point, it is still far from being Windows wide.

What is LINUX distro?

Linux comes in different versions called distributions. What this means is that the basic core of the Operating system is the same though all LINUX versions and all LINUX drivers and software will work on anyone, they will visually and feature-wise be different. Also, they will be more complex for use or they will have different hardware requirements. Choosing the right LINUX distribution is no easy task and we are here to help you by offering you certain points and guides in hopes to direct you on the right path.

What Do You Need the Distro for?

This might be perhaps the most crucial question when trying to decide which LINUX distribution you want to install. Depending on your preferences and goal like work, games, security, media you will need to consider the best distributions in the field of your preference. A very good place to get this kind of information is on DistroWatch. When on-site, navigate to the Distribution category search filter and choose the option best suited to your needs.

What Kind of Software Will You Be Using?

Like the previous question, this one is also your personal preference but it will make difference if you are planning to use a different type of software. If your plans are gaming for example you will want the latest and greatest LINUX kernel version for maximum hardware compatibility. If you are a regular desktop user you will aim for a distro that is updated constantly so you are working with the latest versions of Chrome or Firefox. In some cases, depending on your software you might want to run older but faster distribution.

What Kind of Hardware Will You Be Using?

If your computer is up to date you can run any distribution that you like but if it is an older rig your options might be a little limited. Now depending on the technical characteristics of your computer and its age it may come down to just a few available distributions which are specially tailored to run on old hardware. These kinds of distributions are lightweight and do not take much space but sadly can not offer you the latest and greatest in software but for usual everyday tasks like web browsing, word processing, email viewing, etc they work perfectly fine. You can have a great office machine with proper lightweight distribution offering you all that you need to be able to work.

How Much do you know about computers?

As stated before, LINUX is not as user-friendly as WIndows and your overall technical knowledge can play a big role in deciding which LINUX you want to adapt. If you are more of a casual user then avoid technical distributions which will require to manually tweak tons of stuff, go for more automated ones. If you are a power user however and enjoy wrestling with each detail then perhaps some distro with more command-oriented nature.

What Kind of Community Are You Looking For?

Now you might ask what does community has to do with the operating systems but the same as Windows, LINUX also can have some issues, and sometimes installing drivers will require certain steps to be taken. How it is much easier to find a solution when having a great community surrounding the project I suggest not dismissing this part when choosing your distro. Every community is helpful, but they’re all helpful in different ways. If you would like to read more helpful articles and tips about various software and hardware visit errortools.com daily.

A number of users reported lately that their Windows 10 PCs automatically boots into the BIOS whenever they start their computers. And when they tried to exit the BIOS and restart their computers, it still boots into the BIOS. If you are one of the users who experience the same problem, worry not for this post will walk you through what you can do to resolve the problem. Each time a Windows 10 computer boots, it goes through a lot of processes and one of them is where it checks the computer for any hardware issue such as hard drives, peripherals, as well as external devices. So if it finds some issue, the computer will halt the boot process and will boot into the BIOS. To fix this, there are several suggestions you can try. You have to check if you’ve pressed any key, especially the F2 or F12, or Del keys. You also have to check the peripherals and external devices in your computer or update the BIOS or reset it. For more information, make sure to follow each one of the options laid out below.

Option 1 – Try to check for any pressed key

The first thing you can do is to check for any pressed key. This might not make any sense but a pressed key can actually cause this problem. So you have to check if you have the F2 or F12 or Del buttons pressed since these are hardware keys that are usually set by the OEM to boot into the BIOS.

Option 2 – Try checking the physical device connections

You might also want to try checking if there are other devices that are connected to your PC. This is because the configuration of the BIOS or UEFI might be configured in a way that any external device connected to the computer has a higher boot priority compared to the hard disk.  And if it’s really the case, the externally attached disk might be the drive your computer is trying to boot into and not the hard disk. In such cases, Pen Drives, USB storage devices, CDs, DVDs, and so on, are included in this category of physical device connections.

Option 3 – Try to set a proper boot device

If the Boot Manager wasn’t able to locate a proper boot device, then it could be the reason why your computer boots into the BIOS when you turn it on. Thus, you have to check if there is an available proper boot device. You can usually find it under the Boot priority section. However, if you’re unable to locate your hard drive or SSD under the Boot device, then you have to change the hard drive but you have to check first if it is properly plugged in and that it works on other computers. If it works on other PCs, then the problem lies in the motherboard of your computer, and in that case, you have to consult its manufacturer.

Option 4 – Try to update the BIOS

Updating the BIOS can help you fix the issue but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Now restart your computer to apply the changes made.

Note: If updating the BIOS didn’t help, you might want to consider resetting it instead.

Option 5 – Try resetting the BIOS/UEFI configuration

You might also want to reset the BIOS configuration which will lead to arranging the boot configuration since it is intended by the manufacturer. Note that this will get rid of any blockage in the boot process. All you have to do is take out the CMOS battery for a couple of seconds and then put it back again. After that restart, your computer and will be booted directly into Windows. Resetting the BIOS would also get rid of any password set for BIOS and you need to change your CMOS battery in case it didn’t work.

In case you don’t know, there is a built-in tool in Windows 10, known as Reliability Monitor that provides a day-to-day snapshot of the health of your system. It warns users of any looming issues or disasters before your computer breaks down finally. So obviously, Reliability Monitor is useful, however, there are times when it could behave incorrectly. For instance, it might fail to show you any updates even when they are installed. Thus, if you experience any malfunctions with the Reliability Monitor tool in Windows 10, read on as this post will guide you in updating or working in Windows 10. To fix the problem with the Reliability Monitor, there are several fixes you can check out. You can try to enable the data collection for Reliability Monitor or reset it, as well as put your computer in a Clean Boot State. For more information, refer to each one of the options given below.

Option 1 – Try to enable the Data Collection for Reliability Monitor

The Reliability Monitor tool uses data provided by the RAC Agent scheduled task and it will start to display a Stability Index rating and specific event information 24 hours after the system installation. The RACAgent scheduled task, by default, runs after the operating system is installed. And if it is disabled, it must be manually enabled from the Task Scheduler snap-in for MMC or Microsoft Management Console. Thus, you need to enable the Data Collection for Reliability Monitor to fix the problem.

Option 2 – Try to reset the Reliability Monitor

The next thing you can do to fix the issue with the Reliability Monitor might want to reset it to resolve the problem. If the Reliability Monitor is already open, you have to close it and open it again. After the reset is done, it may take up to 24 hours for the Reliability Monitor to display results again. This should fix the problem.

Option 3 – Troubleshot the problem in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing the Black border issue. 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.

Microsoft has officially announced details about the newest upgrades to its office 365 suite moving forward along with its new OS release. It seems that Microsoft has listened to its user base and feedback since Word, Excel, and PowerPoint are getting much-needed redesign taking into account many suggestions from the community. The new office should feel more like an application suite guiding focus on the interconnection of applications themselves providing users with a much more natural experience of using them.

The new office features so far

From Microsoft themselves:

“This Office visual refresh is based on feedback from customers who asked for a more natural and consistent experience within and between your applications, specifically on Windows. With this update, we deliver an intuitive, coherent, and familiar user interface, using the Fluent Design principles, across all your applications: Word, Excel, PowerPoint, OneNote, Outlook, Access, Project, Publisher, and Visio. We aligned this visual refresh with the design of Windows 11 to provide seamless experiences on your PC.”

It is always refreshing to hear when a company listens to its user base and actually does what is needed instead of trying to invent the wheel.

How to switch

Since beta is already rolling and if you have an active 365 subscription to office suite visual refresh will be automatically available to all Office insiders running beta channel builds. It can be turned on and off using the coming soon feature in the top right corner of the menu in any application. Just click on the megaphone icon to open the coming soon pane and apply settings to all office apps. Note that The Coming Soon feature is not available in Access, Project, Publisher, or Visio. If you turn on the visual refresh in any of the 4 apps mentioned above (Work Excel, PowerPoint, or OneNote), it will also be available in these 4 apps.

Difference themselves

The Home tab menu still has a familiar look with a few tweaks. For example, accessing frequently used Word commands will be a lot easier. By navigating to Designer > Show Quick Access Toolbar, users can add a customizable shortcut ribbon to Word that houses conveniently placed options. Also, the office will not match your Windows operating system color theme so if you have a dark theme enabled, the office will also have a dark color theme. Color palettes are more neutral, corners are a bit softer but customizable ribbons are a win here for me.

Conclusion

There was not much said other than visual upgrades and small tweaks that were supposed to make your life easier but then again Windows 11 itself is in the same boat. I am not sure if this is a great update offering just some visual tweaks and focus on workflow mechanics or just being plain lazy and trying to cash in visuals as a completely new product.

As you know, Windows has a built-in Automatic Maintenance feature that takes care of important tasks such as security scanning and updating, Windows software updates, Disk Defragmentation, System Diagnostics, Disk Volume Errors, and many more. So if you receive an error message saying, “Windows is unable to run automatic maintenance, The maintenance schedule is unavailable”, then this post will guide you in what you can do to resolve this issue. Here are some suggestions you can try if the Automatic Maintenance in your Windows 10 PC is not able to run.

Option 1 – Enable Automatic Maintenance

It is possible that Automatic Maintenance has been disabled so you can try enabling Automatic Maintenance on your Windows 10 PC. To do so, follow these steps:

• Go to Control Panel.
• From there, select System and Security > Security and Maintenance > Automatic Maintenance.
• After that, set the time you want to run the Automatic Maintenance and then check the checkbox saying, “Allow scheduled maintenance to wake up my computer at the scheduled time”.
• Click OK to save the changes.

On the other hand, you can also enable Automatic Maintenance via the Registry Editor. But before you proceed, you need to create a System Restore Point first.

• Tap the Win + R keys to open the Run dialog box.
• After that, type “Regedit” in the field and hit Enter to open the Registry Editor.
• Navigate to the following path:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleMaintenance

• Next, look for the “MaintenanceDisabled” key and then double click on it to open it and then set its value to “0”.
• Click OK and exit the Registry Editor.
• Restart your computer.

Option 2 – Check the Task Scheduler Services status

Majority of the tasks in Windows 10 run via services. So it is most likely that either the Service has been stopped or is set to the manual which is why Windows is unable to run Automatic Maintenance. Thus, you need to change it to automatic mode.

• Tap the Win + R keys to open Run.
• Type “services.msc” in the field and hit Enter to open Services.
• Next, look for the Task Scheduler service and tap the T key on your keyboard which should take you to the services that start with T.
• Double click on the Task Scheduler service and select the Automatic option under the Startup Type.
• If it is not started yet, click on the Start button.
• Then click Apply and OK to save the changes.

Option 3 – Check the Status in Task Scheduler

You can also try checking the status in the Task Scheduler. Just open the Task Scheduler > Task Scheduler Library > Microsoft > Windows > TaskScheduler. From there, make sure that Idle Maintenance, Maintenance Configurator, and Regular Maintenance are enabled.

Option 4 – Run the System File Checker

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Automatic Maintenance issue. 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 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.
• Restart your PC.

Virtual Reality or VR for short has come a long way from its infant stage and as 2022 is in half period we are looking at the VR market and reflecting on what has changed in one year. For starters, games have increased in quality and quantity while the hardware price has decreased making the whole VR experience a little closer to a wider audience.

Many companies have tried to get on the VR bandwagon but also many have failed. What remained are staples in VR hardware from large companies that have started with VR early and kept improving their headsets.

So with great pleasure, we are presenting the remaining best 3 virtual headsets so far of 2022 brought to you from Sony, Valve, and Meta.

SONY PLAYSTATION VR

If you want VR on consoles then there is really one option, and that is SONY VR. Premium Virtual Reality solution from SONY, sadly you can do this only on Playstation 4 and Playstation 5. Sony managed to pull off great quality hardware and packed with its exclusives on playstore at a very affordable price that is still cheaper than other products.

While waiting for the Sony PlayStation VR2 headset this one is still a great option and quality is still among the top of the game. From the time of its release until today, many AAA titles have been released for it as exclusives that you can not play any other way and some of them are really worth it.

VALVE Index

Altho there are headsets like HTC Vive Cosmos Elite that have some features that place it as a better solution than Valve Index, Index is still an overall better VR headset as a whole product but its price is something that is keeping it still way out of reach of your standard user. The price, however, is really an illusion since it applies only when buying the system first time, you see Valve has created this headset as a modular design system making it upgradable meaning that you can, for example, buy newer controllers only and they will work perfectly with rest of hardware.

The modular design will save you money when you want to upgrade your VR system but as said entry price is steep. Besides its somewhat higher price than competitors, it is also notable that Index is a positional tracking VR set which means that it relies on a base station in order to locate the user. This means that once set, it is not so easy to change its location of use.

However, its quality and steam use are unmatched, high-quality games and compatibility that no other headset with steam will even pull off probably make Index one of the 3 best headsets out there. Half-life Alyx, arguably and currently one of the best VR games ever made so far was specifically designed for Valve Index and other games are behaving also incredibly nice with this headset, so if you want a great powerhouse for PC VR gaming, you will no go wrong in purchasing Valve Index.

META QUEST 2

Cheapest of the three and coming in various iterations, Meta has established itself from the beginning as a leading player in VR technology with its oculus line of products. Quest 2 is the next product in their line and it comes with 128GB and 256GB versions.

Meta has removed the need for the Facebook account for its VR systems and now you can use them without the need to send any kind of data to meta. Priced fairly for its entry 128 models this standalone VR set improves in any way possible from its previous iteration and sets the bar for what will come in VR's future.

Offering both wired and wi-fi connection with its standalone battery Quest 2 also is packed with a large library of games and it is user friendly as your typical game console but still allows some under-the-hood tinkering if you wish so.

Also, Meta's Vr solution since it uses inside-out tracking makes it incredibly easy to just pick it up and carry it with you wherever you go.

There are cases when you encounter some issues while updating your Windows 10 computer. One of these issues is the error 0x80240034. This particular error is a Windows Update Error that appears on the Windows Update pane every time an update fails to install. When this happens, your Windows Update will only get stuck at 1% and nothing happens afterward and eventually fails. If you click on the View Installed Update History, you will see the error code 0x80240034 for the failed updates. You will see this error each time you try to update your Windows PC. Take note that this issue doesn’t only happen to a specific version of the Windows Update but on various different Windows builds based on many users. What’s more, is that some users are also seeing a different error code when their Windows Update fails but they still end up seeing the error code 0x80240034 when they check the Windows Update history. At the time of writing, it isn’t determined yet what really causes this error but it’s most likely due to some corrupted files in the computer which is why the most common solution you can try is resetting the Windows Update cache. On the other hand, other users also resolved the issue by using the ISO and selecting the “Do not keep previous settings” option during the Windows Update so it might be something to do with transferring the previous settings through the update client. For clear instructions in fixing this issue, refer to the two options provided below.

Option 1 – Try to clear the Windows Update Cache/Distribution Folder

As mentioned earlier, a lot of users tried clearing the Windows Update cache to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow the steps below.

• Step 1: Tap the Windows key once.
• Step 2: Next, type in “command prompt” in the Windows Start Search, and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option from the context menu.
• Step 3: After opening Command Prompt, type in “net start wuauserv” and hit Enter.
• Step 4: Then type in “rmdir %windir%SoftwareDistribution /S /Q” and hit Enter.
• Step 5: Now type in “net start wuauserv” and hit Enter. Once it’s done, try updating your Windows PC again, it should now work just fine.

Option 2 – Update Windows via ISO file

If option 1 didn’t work for you, you can try this second option of updating your Windows 10 computer using an ISO file which means that 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 error 0x80240034. 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.

• Step 1: Click this link and then click the Download Tool Now button.
• Step 2: 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.
• Step 3: Now select the ISO file option in step 5.
• Step 4: After that, you should now have an ISO file.
• Step 5: Next, go to the location where you’ve downloaded the ISO file.
• Step 6: Then right-click on the Windows 10 ISO file and select the Open with an option and then select File Explorer.
• Step 7: Now click on “setup.exe” and follow the next instructions that appear on the screen. When asked, you have to select either: Nothing (clean install) or 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.

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.

TPM 2.0 requirement for Windows 11 has produced a lot of discussions since it was announced. A lot of somewhat older hardware seems to be left behind with this decision from Microsoft. So naturally, when something like this is announced, especially when it is stated it is the must-have thing, people find a way to break it and to prove it is not the case. In that spirit, I am proud to present you with not one but three-way you can install Windows 11 on hardware that does not has TPM 2.0. Please note that by bypassing this you will not be able to use some Windows 11 features tied to modules like Device encryption, vTPM in Hyper-V, and all TPM-related services. I will cover methods from the most simple and straightforward ones to the more complicated using registry editor.

Bypass TPM with changing installation media

For this method to work you will need both Windows 10 ISO and Windows 11 ISO since it will require some file copying between them. You will also need Rufus or another tool to make a new installation media once files are copied All you have to do in this method is to go into your Windows 10 ISO and delete the install.esd, then just copy install.wim from Windows 11 installation media into the same place, and you are done. Make install ISO with Rufus and install Windows 11.

Change DLL on installation media method

For this method, you will need everything like in the previous one and the process is almost the same, but this time instead of migrating the whole installation file, we will just replace the appraiserres.dll file. Copy appraiserres.dll file from your Windows 10 installation media over the same file on Windows 11 installation and you are good to go.

Bypassing TPM via registry editor

If for some reason previous easy solutions have not worked for you do not lose hope just yet, there is one more way you can bypass TPM. In this given method you will not need Windows 10 installation media but the process is a little more complicated than previous ones.
