How to Fix Windows Upgrade error 0xa0000400

In case you don’t know, Windows contains a feedback mechanism that generates error reports from hardware and software problems. These reports are temporarily stored in the system and send them back to Microsoft so that it can find solutions to the reported problems and fix them in the upcoming updates.  However, as time goes by, these reports actually take a lot of space in your computer which is why end-users like you are free to delete them with the help of the new Free Up Space feature in Windows 10. As useful the Free Up Space feature may be, there are times when you won’t be able to use it for some reason which is why in this post, you will be guided on how to use alternative ways in deleting very large System queued Windows Error Reporting file, some of which may run in Gigabytes. Every time the Windows Error Reporting or WER sends out an error file and looks for a solution, the WER server at Microsoft sends out a solution instantly. And if the solution is under investigation or is unknown, then you will be notified about it right away and will be asked for more details. As mentioned, even though the Free Up Space feature in Settings will be able to clear the error reporting files, there are instances when it won’t be able to delete very large System queued Windows Error Reporting files. Alternatively, there is an option to delete these files using the Disk Cleanup Utility. Feel free to select which option you’d like to use to get rid of Windows Error Reporting Files.

Option 1 – Delete Windows Error Reporting Files via Settings

• Go to Settings.
• From there, go to System > Storage > Free Up Space and then click on it to launch it.
• Afterward, give it some time to populate all the files and folders. Once it’s done, select “System created Windows Error Reporting files” to mark its checkbox while leaving the other options unchecked.
• Next, click on the Remove files button to delete all the Windows Error Reporting files from your computer.

Option 2 – Manually delete the Windows Error Reporting Files

• Tap the Win + E keys to open File Explorer.
• Next, enable the Hidden Files view from the menu.
• Then go to C:/ProgramData/MicrosoftWindowsWER.
• From there, you will see various folders like LocalReportArchive, ReportArchive, ReportQueue, and Temp.
• Open each one of the aforementioned folders and delete the archive files. Note that these files will have names similar to “00c58c1f-b836-4703-9bcf-c699ca24d285”.

Note: If you are not able to delete any of these files, you have to take ownership of the folder. To do so, refer to these steps:

• Right-click on the folder and then select Properties.
• Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
• After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
• Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
• Now edit the permission to Full Control for “Everyone”.
• Click OK to save the changes made and then exit.

On the other hand, if you do not want to go through all these troubles in deleting the Windows Error Reporting files, you can just disable it especially if it already becomes a daily annoyance as the files generate every day and their sizes are mostly gigabytes. And besides, there are times when these files do not make it to the Microsoft WER server and end up only occupying a lot of space for nothing.

Hello everyone and welcome to another great tutorial from errortools.com I hope everyone is feeling great and that you are prepared to boost the performance of your computer. This time we will speed up Windows startup time and overall performance by eliminating startup programs that we don't need and do not use. Microsoft itself and some application developers tend to have some applications or some services always active and set to be loaded on Windows startup. If you want to change which of these applications are starting up with your Windows and change them, follow this easy guide and you will be speeding up your Windows in no time. First thing is to open a task manager, fastest and most direct way of doing this is with a keyboard combination of CTRL + SHIFT + ESC When Task Manager opens, click on the startup tab on top. Once you click on startup you will get a list of applications that are set to be started when Windows is booted. You can now click on the application and then click on disable on the bottom button, the application status will update in task manager to disabled and it will not be booted anymore when Windows starts. In this same manner, you can enable back some applications if you changed your mind about them. Please note that some applications are using some services and must have them running or they will not work properly. The best practice is to disable applications you are positive you will not use or use rarely so you do not want them to slow down Windows.

What is the Error Code 0x6d9?

If you have a firewall installed on your system, you may come across the error code 0x6d9.  This error occurs when opening Windows Firewall with advanced security. The error code 0x9d9 is displayed as:

“There was an error opening the Windows Firewall with Advanced Security snap-in. The Windows Firewall with Advanced Security snap-in failed to load. Restart the Windows Firewall service on the computer you are managing. Error code: 0x6D9”

This occurs when the Windows Firewall service is missing. The service doesn’t start due to permission errors on various registry keys. It is a critical blue screen of death error code that turns the computer screen blue and causes the Windows to shut down. If this error code is not fixed it may start appearing more and more frequently resulting in total system corruption.

Solution

Error Causes

Virtually, the underlying cause for Windows Firewall error code 0x6d9 is a damaged registry. The registry is the database of the system that saves all the activities including web browsing and programs installed and uninstalled and junk files on the PC. The registry saves all the information in the RAM, your hard disk. As the disk gets filled with files, it then requires more power to run which impacts the performance of the PC and slows it down. Simultaneously, since the hard disk is overloaded with data, it exposes the registry to file damages, fragmentation, and corruption which then eventually causes hindrance in running calling programs and running them on your system because files are either corrupt or missing. Other than cluttered disk issues, registry errors also occur due to viral and malware attacks. If the Firewall is inaccessible, your system is prone to malware.

Over the years, the Windows 10 updates have smoothened but that does not mean that it no longer encounter some issues. One of these issues is when it gets stuck. As you know, Windows automatically checking for updates regularly or when you click the “Check for updates” button. However, if the Windows 10 update is taking forever and seems to be stuck, then you’ve come to the right place as this post will guide you on what you can do to resolve the problem. This kind of scenario in Windows Updates can be quite confusing especially since there is no response or any indication of what is really happening since you don’t know if the update is still downloading or if it’s already getting installed. To resolve this problem, there are several options you can check out. You can try to exit settings and restart your computer. You could also try to restart the services related to Windows Update or clear both the Software Distribution and Catroot2 folders, as well as run a System File Checker scan. For more details follow each one of the given steps below.

Option 1 – Restart your computer

The most basic thing you can do to fix the problem is to restart your computer. It usually works in fixing common issues like the Windows Update getting stuck at the “Checking for updates” screen. However, if it didn’t work, proceed to the next given options below.

Option 2 – Reset Windows Update components

If the first two options did not work then you might want to reset the Windows Update components manually. Follow the steps below to reset them.

• Open Command Prompt with admin privileges.
• After that, type each one of the following commands and hit Enter after you key in one after the other.
  • net stop wuauserv
  • net stop cryptsvc
  • net stop bits
  • net stop msiserver

Note: The commands you entered will stop the Windows Update components such as Windows Update service, Cryptographic services, BITS, and MSI Installer.

• After disabling WU components, you need to rename both the SoftwareDistribution and Catroot2 folders. To do that, type each one of the following commands below, and don’t forget to hit Enter after you type one command after the other.
  • ren C:WindowsSoftwareDistribution SoftwareDistribution.old
  • ren C:WindowsSystem32catroot2 Catroot2.old
• Next, restart the services you’ve stopped by entering another series of commands. Don’t forget to hit Enter after you key in one command after the other.
  • net start wuauserv
  • net start cryptsvc
  • net start bits
  • net start msiserver
• Close Command Prompt and reboot your PC.

Option 3 – Try checking Services Dependencies

Dependencies of a Windows Service in Windows 10 are when windows services depend on other services. Such is the case with the Windows Update service – it also depends on three different services such as the Remote Procedure Call or RPC service, DCOM Server Process Launcher, and the RPC Endpoint Mapper. Meaning to say, if two of these services are not working as expected, then the dependent service will also be affected. This could be the reason why the Windows Update service could not start.

• 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 following services:
  • Remote Procedure Call (RPC) Service
  • DCOM Server Process Launcher
  • RPC Endpoint Mapper
• After you find these services, double click on each one of them and check whether the Startup type for all is set to Automatic and the Service status is set to Running or not.
• If the service status is not running, then click the Start button. Afterward, check if you can now run the Windows Update service.

Option 4 – Check the Background Intelligent Service and the Cryptographic Service

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter or click OK to open Services.
• From the list of Services, look for the following services and make sure that their Startup type is as follows:
  • Background Intelligent Transfer Service – Manual
  • Cryptographic Service ­– Automatic
• After that, check if the Service status of the listed services above is set to Running. If they’re not, click on the Start button to start these services and then check if you can now enable the Windows Update service or not.

Option 5 – Try running the System File Checker

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 your screen is stuck at “Checking for updates”. 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.

• Restart your computer.

In previous versions of Windows changing the system, the font was a pretty straightforward process, but it seems Microsoft did not want this feature to keep for whatever reason and there is no option as of the time of the writing of this article to do it in standard options in Windows 10. But do not worry, you are still able to customize your Windows and choose which font would you like to see inside it in all of its dialogs. You can choose whichever font you desire, the only prerequisite is it to be installed on your system. This guide will require you to change values in the registry of Windows itself so please follow step-by-step instructions and always make a backup of the registry before changing it in order to prevent some permanent Windows issues. All of that being said, let's start.

Setting new font

First thing is to open notepad, in the notepad paste the next block of code:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts] "Segoe UI (TrueType)"="" "Segoe UI Bold (TrueType)"="" "Segoe UI Bold Italic (TrueType)"="" "Segoe UI Italic (TrueType)"="" "Segoe UI Light (TrueType)"="" "Segoe UI Semibold (TrueType)"="" "Segoe UI Symbol (TrueType)"="" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] "Segoe UI"="NEW_FONT"

Where in "Segoe UI"="NEW_FONT" instead of NEW_FONT you need to write the exact name of the font that you wish to use as a system font. Once you have replaced the default system font with your desired one, go to File and save as, from file type drop-down menu, choose all files and save this file as .REG type giving it whatever name you wish. When the file is saved, close notepad, right-click on the saved file and choose the merge option. Confirm with YES and click on OK. Reboot your system and your Windows will now use the font of your choice as its default system font.

Restoring default font

If you wish to return the old default system font as it was, follow the same steps but in your notepad paste this code:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts] "Segoe UI (TrueType)"="segoeui.ttf" "Segoe UI Black (TrueType)"="seguibl.ttf" "Segoe UI Black Italic (TrueType)"="seguibli.ttf" "Segoe UI Bold (TrueType)"="segoeuib.ttf" "Segoe UI Bold Italic (TrueType)"="segoeuiz.ttf" "Segoe UI Emoji (TrueType)"="seguiemj.ttf" "Segoe UI Historic (TrueType)"="seguihis.ttf" "Segoe UI Italic (TrueType)"="segoeuii.ttf" "Segoe UI Light (TrueType)"="segoeuil.ttf" "Segoe UI Light Italic (TrueType)"="seguili.ttf" "Segoe UI Semibold (TrueType)"="seguisb.ttf" "Segoe UI Semibold Italic (TrueType)"="seguisbi.ttf" "Segoe UI Semilight (TrueType)"="segoeuisl.ttf" "Segoe UI Semilight Italic (TrueType)"="seguisli.ttf" "Segoe UI Symbol (TrueType)"="seguisym.ttf" "Segoe MDL2 Assets (TrueType)"="segmdl2.ttf" "Segoe Print (TrueType)"="segoepr.ttf" "Segoe Print Bold (TrueType)"="segoeprb.ttf" "Segoe Script (TrueType)"="segoesc.ttf" "Segoe Script Bold (TrueType)"="segoescb.ttf" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] "Segoe UI"=-

Reboot your system and your Windows will now revert the font of your choice as its default system font.

If you suddenly find your Windows 10 computer stuck on the “Preparing to configure” screen for quite a long time now after you run Windows Update, read on as you will be guided on how you can fix that issue in this post. During an update process, there’s a lot of things that go on in the background which is why Windows Updates take quite a while before it finishes. It can be at 25%, 50%, or even 100% but the only message you’re going to see on your screen is the “Preparing to configure Windows, Don’t turn off your computer”. However, if you notice that the Windows Update is taking a longer time than it’s supposed to, the first option is to wait some more but if it’s still the same, then there’s definitely something wrong. This kind of issue occurs when Windows Update fails to configure in short correctly download and install the update. When this happens, it will revert all the changes which are why you were advised to wait for a couple of hours. There are two possibilities why your computer is stuck on the “Preparing to configure Windows, Don’t turn off your computer” screen. The first one is that the Windows 10 operating system is installing any updates. The second one is when the user profile takes time to load or encounters an error. There are several options you can try to fix the problem. You can try running System Restore or boot your computer in Safe Mode or repair the corrupted profile via Registry Editor. You might also want to try using installation media to boot and repair your computer if the other options didn’t work.

Option 1 – Perform System Restore

• 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.

Note: If you can’t boot into the desktop of your computer, you can run System Restore in the Advanced Startup Options by following these steps:

• Boot your computer into the Advanced Startup Options screen.
• From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
• Now select Troubleshoot > Advanced Options > Command Prompt.
• After that, type “rstrui” and hit Enter to execute the command which will start the System Restore process.
• Once it’s done, restart your computer.

Option 2 – Boot your computer in Safe Mode

You can try to tap the F8 key if you have it enabled in your Windows 10 computer, as you start your system to boot into Safe Mode. Once your computer is in Safe Mode, you can access the Start Menu and the Mouse and Keyboard. Aside from that, you can also access your files and other built-in tools in Windows such as Command Prompt, PowerShell, Computer Manager, Device Manager, Event Log Viewer, and many more. On the other hand, if you haven’t enabled the F8 key, you can just go to the Advanced Startup options to boot your computer into Safe Mode. Once you’re there, select Troubleshoot > Advanced Options > Startup Settings > Restart > Tap the number 4 key. After that, your computer will restart in Safe Mode. If you want to reboot into Safe Mode with Networking instead, you can tap the number 5 key and for Safe Mode with Command Prompt, tap the number 6 key. Once your computer is in Safe Mode, you can use any of the built-in tools to restore your computer or troubleshoot the problem that’s causing your computer to get stuck at the “Preparing to configure” screen.

Option 3 – Try to repair your corrupted profile via Registry

In this third option, you can try to repair the corrupted profile using the Registry but before you proceed, take note that you can only try this if you can boot into your desktop and if you can, make sure to create a System Restore Point and then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter or click OK to open the Registry Editor.
• Next, go to this registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList
• Once you’ve opened the registry key, you should see a list of all the user profiles on your computer. Now click on each S-1-5 folder and look for the “ProfileImagePath” entry and double click on it to check which user account it is related to. You will see a path like “CUsersACK” where “ACK” is the username.
• You should know which of the user account is corrupted. Just look for a key named “RefCount” and change its Value data to “0” and click OK. And if it isn’t available, simply right-click on the right pane and create it.
• After that, double click on the key named “State” and make sure that the Value data is “0” and click OK.
• Exit the Registry Editor and restart your computer to apply the changes made.

Option 4 – Try to use installation media to boot and repair your computer

Another thing you can try to resolve the issue is to use the Windows installation bootable media so you can boot and repair the operating system. To use it, follow these steps:

• You need to first create an installation media which has the dame version of the operating system installed in your computer.
• After that, once you reach the Install Windows screen, click on the “Repair your computer” link.
• Wait until the repair is completed and then shut down your computer
• Now once your computer has restarted, check if it can now boot properly.

BSOD or Blue Screen of Death errors are one of the toughest issues you can encounter in Windows 10 as well as the hardest ones to resolve as they simply shut the system down or restart it abruptly and claims that it isn’t possible to boot Windows again. One of the difficult BSOD errors is the Machine Check Exception BSOD error. The reason why it is hard to fix is that in most cases, it occurs soon after Windows loads which gives users little to no time in resolving it. To make things worse, the system also freezes right before it displays the blue screen error and shuts the system down. Usually, the Machine Check Exception Stop error occurs due to the failure or overstressing of the hardware components. And in the case of almost all Blue Screen of Death errors, the issue usually has something to do with the drivers. So if you frequently see this BSOD error from time to time, now’s the time to act on it by following the solutions given in this post.

Option 1 – Update the Device drivers

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. Look for the device driver you and then select either “Update driver” or “Uninstall device”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• If you have chosen to uninstall the driver, follow the screen options to complete the process and then restart your PC.
• Connect the device and Scan for hardware changes – you can see this option under Device Manager > Action.

Option 2 – Try running the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that 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.
• From there, 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.

Option 3 – Try running the System File Checker

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 with good system files that might be causing the Machine Check Exception BSOD 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 – Run the Startup Repair

In the Blue Screen where the Machine Check Exception error is displayed, tap the F8 key to go to the Startup Settings where you can find Startup Repair and then run it. Note that this is a must-try option especially if you are unable to start your computer and if you can use your computer for a few moments.

Option 5 – Run the DISM tool

There are cases when the Machine Check Exception error is caused by the Windows System Image so you need to repair it using the DISM or Deployment Imaging and Servicing Management 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 /CheckHealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 6 – Try resetting the BIOS

If you have made some modifications in the BIOS that might have caused this error, you have to revert those changes to resolve the issue. On the other hand, if you have made a couple of changes and you do not remember which is which, you might have to reset the BIOS.

Option 7 – Try resetting Windows 10

To fix this BSOD error, you can try resetting Windows 10. Doing so won’t get rid of any file in your system – instead of erasing all your media files and documents, this reset option resets all the system settings and files.

One of the great remote assistance software that helps you remotely access and control computers is TeamViewer. However, despite how efficient it is, there are still times when it throws up some errors and one of them is when TeamViewer is not able to connect and throws an error that says, “No connection to partner, Partner did not connect to router, Error Code WaitforConnectFailed”. This kind of error in TeamViewer mostly occurs when the Partner computer is not connected to a network. On the other hand, it could also occur when they are connected to a network so there are various causes for this issue. It could also be that the installation of the program itself was at fault or there is an incompatibility between the TeamViewer versions installed on both the computers and so on. Although there are several causes for this error, the potential fixes are still the same. You can try to restart the network or allow Full Access Control to TeamViewer or flush the DNS cache. For more information, refer to the following options but before you proceed, make sure that both your Windows 10 computer and TeamViewer program are updated to their latest stable versions.

Option 1 – Reboot your router

All you need to do is reboot the router from its Admin panel or you can also turn it off manually and turn it back on after a couple of seconds so that it can completely reboot. Once you’re done, try accessing your server again and see if the error is now fixed.

Option 2 – Allow Full Access Control to TeamViewer

• First, open TeamViewer, and then from the Menu bar, click on Extras.
• After that, click on Options and select Advanced from the left side navigation panel.
• Next, click on the “Show advanced options” button located on the right-hand side.
• Then select Full Access from the drop-down menu of the Access Control option under the “Advanced settings for connection to this computer section”.
