Fix error code 0x80190001 in Windows

If you suddenly encounter PFN_LIST_CORRUPT Blue Screen of Death error while using your computer then it means that the Page Frame Number or PFN list is corrupted. Page Frame Number is an indexing number used by the hard drive to find out the location of every single file on the physical disk. This kind of Blue Screen error is usually caused by a driver that’s passing a bad memory descriptor list and it can either be temporary or permanent. And so to fix this particular BSOD error, read on as this post contains a couple of suggestions that could help. Keep in mind that when you get a Blue Screen error like PFN_LIST_CORRUPT, the power connection to your PC must not be interrupted and so if you are using a laptop, it’s best if you connect it to a power source. On the other hand, if creating a dump from 0% to 100% takes up more than 5-10 minutes, then you have to force shut down your computer by pressing and holding the Power Key for 10 seconds or at least until the CPU lights turn off. After you do that, proceed to the troubleshooting tips prepared below.

Option 1 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like PFN_LIST_CORRUPT. It 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 2 – Run a System File Checker scan

You can also try to run a System File Checker or SFC scan in order to scan your computer for corrupted files that might be the cause behind the PFN_LIST_CORRUPT error. Once it finds any corrupted system files, it will automatically fix them. To run System File Checker, here’s what you have to do:

• 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 after the scan is completed.

Option 3 – Check for any hard disk errors

• On your desktop, right-click on the “This PC” or computer icon and then select Manage to open the Disk Management. Here you get to check your drive’s health.
• Next, click on Disk Management on the left side panel.
• From there, check the state of your drives. If it shows that all your partitions are healthy then it means all is good and that the problem may have something to do with some physical issues with your hard drive.

You might also want to run the CHKDSK utility to help you fix any issues with your hard disk. 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 following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC and then check if the Blue Screen error is now fixed or not.

Option 5 – Disable OneDrive

The PFN_LIST_CORRUPT error might also be caused by OneDrive. Thus, you have to try disabling this program to resolve the problem.

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Once the Task Manager is open, click on More Details located at the bottom left portion of the window.
• Then go to the Startup tab and select Microsoft OneDrive and then click Disable.

Distributed Component Object Model or DCOM is a module on Windows computers that allows computers to run programs over a network to another computer. It is a software component from Microsoft that allows COM objects to communicate with each other while that program is remotely running over the network. The COM Model is another extension of the DCOM model which both work together in order for the intended task to be executed. To make this module work, there are three components needed such as the Class Identifier or CLSID, the Programmatic Identifier or PROGID, and the Application Identifier or APPID. However, DCOM does not always work as expected as it could still encounter some errors. One of them is error 1084. Because of this error, the execution of programs in a remote computer on the network would be interrupted. So if you encounter the DCOM error 1084 when you try to start a service like running the DISM tool or in other scenarios on your Windows 10 computer, then this post could help you. Refer to the instructions given below to start troubleshooting the problem.

Option 1 – Try checking the status of DCOMLAUNCH Service or DCOM Server Process Launcher and its 3 dependencies

The DCOM Server Process Launcher service launches both COM and DCOM servers in response to object activation requests. This is why if this service is stopped or disabled, the programs that are using COM and DCOM won’t properly function. So you need to make sure that the DCOMLAUNCH service is running.

• 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 “services.msc” in the field and hit Enter to open the Services Manager.
• Next, check the following services:
  • DCOM Service Process Launcher
  • Background Tasks Infrastructure Service
  • Local Session Manager
  • Remote Procedure Call (RPC)
• Then right-click on each one of the services and click on their Properties.
• After that, select Automatic from the drop-down menu of Startup Type and make sure that all the aforementioned services are Running.
• Now click OK for each one of the services.

Option 2 – Troubleshoot the problem in a Clean Boot State

There are instances that some conflicting programs installed in your computer might be the one that’s causing DCOM error 1084. 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.

Option 3 – Try to use the DISM tool

You might want to repair potentially corrupted files in your system as having them could also trigger the DCOM error 1084. To repair these corrupted system files, you can run the DISM commands:

• Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
• After that, input each one of the commands listed below sequentially to execute them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism /Online /Cleanup-Image /RestoreHealth

• Once you’ve executed the commands given above, restart your computer and check if the DCOM error is now fixed.

Option 4 – Reset your computer

• Tap the Win key or click on the Start button located in the Taskbar.
• Then click on the Power button at the bottom right portion of the screen.
• Next, press and hold the Shift key on your keyboard and then click on Restart. This will restart your Pc into the Advanced Startup options.

Note: Once you have access to the Advanced Startup options, you have to go to the setting which allows you to Reset your Windows 10 PC. All you have to do is select Troubleshoot > Reset this PC to reach the following screen Afterward, select either the “Keep my files” option and then proceed to the next on-screen instructions that follow to reset your Windows 10 computer without losing your files.

When we get ourselves a new USB stick, new hard drive, or any storage device not including optical drives they are usually preformatted and ready to be used out of the box. However, reformating them has several benefits and while we are reformatting we can choose in which file system format we want the memory to be formatted. In this article, we will compare and explore 3 typical and standard format options you can get while formating a new media in Windows 10.

FAT32

The oldest one on the list, coming all the way from DOS days. Great for devices that need to be plugged in different operating systems and for USB flash drives. Its advantages are compatibility with all major operating systems and little memory usage comparing to other ones. However, the file system is limited to file sizes of the maximum capacity of 4GB and partitions can not exceed more than 32GB.

NTFS

First introduced in Windows NT this file system offered slower performance than FAT32 and somewhat limited usability but the main advantages were more stability and fewer errors. Its main advantages are support for files larger than 4GB and partitions larger than 32GB along with the ability for on the file encryption, main disadvantage would be limited operating system usage, NTFS can not be used on systems that work on FAT32 like MS-DOS for example or older versions of Windows. The best usage for this file system is in internal hard disk drives and system drives.

exFAT

New kid on the block, well at least from the perspective of the previous 2. exFAT offers unlimited file sizes and unlimited partition sizes but at a price that is even more limiting than NTFS. Some Linux distributions will require a driver to be installed in order to see the exFAT partition. The best use is in storage, in external hard drives. That's it, 3 major file systems, we hope that you have managed to learn something new today, and remember to drop by tomorrow for more articles about advice, tips, tricks, and troubleshooting.

Windows users need to be on high alert. Microsoft has confirmed a critical vulnerability has been found in all versions of Windows which presents an immediate threat, and you need to act now. A critical new zero-day hack has been found which affects all Windows versions. Tracked as CVE-2021-34484, the “zero-day” flaw enables hackers to breach all versions of Windows (including Windows 10, Windows 11, and Windows Server 2022) and take control of your computer. Microsoft mistakenly thought it had patched the vulnerability (which was first found in August) when it was publicly disclosed in October. But the fix itself was found to be flawed, something the company admitted, and this drew even more attention to the vulnerability. Microsoft subsequently promised to “take appropriate action to keep customers protected” but two weeks later, a new fix has still not arrived. Luckily the third-party security specialist 0patch has beaten Microsoft to the punch with a ‘micropatch that it has now made available for all Windows users “Micropatches for this vulnerability will be free until Microsoft has issued an official fix," 0patch confirmed. You will need to register for a 0patch account and install its download agent before the fix can be applied, but with 0patch fast becoming a go-to destination for hot fixes which beat software companies to the punch this is a no brainer. Hopes will be high that Microsoft can release an effective patch sooner rather than later but, until then, all Windows users must act now if they want to be safe.

Thorconnwndclass error is an Outlook error that has recently reared its head. Known to create several problems in the proper functioning of the Outlook application, this error is essentially a constituent of the Norton Antivirus Crash Guard Symantec component. That’s why those using the Norton Antivirus program are most likely to encounter this error.

Solution

Error Causes

When the Thorconnwndclass error occurs, the Outlook closes unexpectedly, users encounter problems while sending or receiving emails and, performance of Outlook is degraded and this happens because issues arise while accessing the PST file. Because of this damaged PST file, stored data is unavailable for access. Other factors that trigger the Thorconnwndclass error are listed below.

• Corrupt or damaged Outlook Add-ins
• Corrupt or damaged Outlook bar
• Unfinished Outlook installation
• Faulty settings
• Thorconnwndclass Norton is being used with Outlook

Regardless of the underlying factors that lead up to the occurrence of this error, it's of paramount importance that workarounds are implemented to ensure desired performance of Outlook in the long run.

Further Information and Manual Repair

While there are several ways to rectify this error, some of the most common ones are listed below as follows.

• The most effective solution is the PST file repair tools available online. These tools use a complex algorithm and thoroughly scan the PST file and repair it as needed. This resolves the Thorconnwndclass error that one encounters in Outlook. Usually such software have an easy to use interface and can easily be used, without the need for the user to have a strong technical background. Another advantage of using these software available online is that they not only repair the file, but they often play a pivotal role in retrieving inaccessible or lost data.

Some other tips for manually resolving this problem are listed below as follows.

• First and foremost, disable your Norton Antivirus program if it’s installed on your system. Now, open the Outlook application in Safe Mode. Since this problem may also be triggered by damaged or corrupt Outlook add-ins, it is strongly advised that you disable or uninstall them. Now, you will come across some .dat files. Rename them by changing the existing .dat files to new .dat.
• Another useful approach is to employ the Inbox Repair tool offered by Outlook.
• Finally, one can also use the scanpst.exe file to fix any problem or error that resides within the  Outlook application.

If you are trying to install Office but got an error saying, “Something went wrong, Sorry we ran into a problem” with error codes 12002-4, 12007-4, or 12152-4 instead, this indicates that you have a problem with your internet connection. Aside from internet connection issues, the problem could also be due to some programs that block the installation files to be downloaded so when they time out, you get these error codes. There are several options you can try to fix the 12002-4, 12007-4, or 12152-4 error codes. You can try to install Office offline or turn off the proxy server or VPN (if you’re using one). You can also try to temporarily disable your antivirus program or Firewall. Refer to the given potential fixes below to troubleshoot and fix the problem.

Option 1 – Try to install Office offline

The first thing you can do if you encounter the error codes 12002-4, 12007-4, or 12152-4 when installing Office is to download an offline copy of Office especially when you’re certain that your internet connection is slow. Once you’ve downloaded it, install it again. The offline installer will download both the 32 and 64-bit versions of Office. Keep in mind that you must download the correct version.

Option 2 – Disable the Proxy server

The first thing you can do is to try disabling the Proxy server as it might be the reason why you’re getting error 0x80244022 for Windows Updates. To disable the proxy server, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it. In addition, if you are also using a VPN, you can try to disable it as well.

Option 3 – Temporarily disable the Antivirus and Firewall

As mentioned earlier, the downloading of the installation files could be blocked by either the antivirus program or Firewall or it could be both especially when the link seems suspicious. To fix this problem, you have to disable both the antivirus like Windows Defender and the Firewall or any third-party software you might be used temporarily and then download the installation files again. Once the download is completed, make sure to turn on the antivirus program and the Firewall again. On the other hand, you can also try downloading in a different location which also means that you have to try a different network. It could be that the load on the current system is too high which is why it’s not able to offer enough bandwidth to download the installation files of Microsoft Office.

It seems that Microsoft is going to offer subscription and sales of individual office applications in the Windows Store. The office package will still be available as a package but for the first time, we will get single applications as standalone ones available for purchase. This is a very interesting decision by Microsoft and I fully support it, this time users will be able to pay less and to choose only applications that they need instead of paying for the whole package and not using it.

If you are running the Windows Update service but decided to stop it but you encountered an error message instead that says, “The Windows Update service could not be stopped”, read on as this post will help you fix the problem. This kind of error appears when you use the Command Prompt to stop the Windows Update service, especially if you are using cmd without admin privileges. A lot of users reported that they were not able to disable the automatic Windows Update in Windows 10 using Command Prompt. The command used to stop the Windows Update service is the “net stop wuauserv” command. However, when some users executed this command, they got the error message. So if you are one of these users that can’t stop the Windows Update Service via Command Prompt, you can try to fix that using PID as well as checking the Service dependencies. For more details, follow the given options below.

Option 1 – Try to stop the Windows Update service via PID

In case you don’t know, each running service or process has its own unique ID or PID and you can find it in the Task Manager. You can use it to stop the Windows Update service. How? Refer to these steps:

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Next, go to the Services tab and look for the service named “wuauserv” and get its PID.
• After that, type “cmd” in the Windows Start search and right-click on Command Prompt from the search results and then select the “Run as administrator” option.
• After opening Command Prompt with admin privileges, execute this command: taskkill /f /pid <PID>

Note: You need to replace “<PID>” with the PID of the “wuauserv” service. For instance, the PID is 6676, then this is how the command should be “taskkill /f /pid 6676”.

• After you execute the command, you will this message on your screen, “SUCCESS: The process with PID 6676 has been terminated” which indicates that you have stopped the Windows Update service successfully.

Option 2 – Try to check the Service 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 dependant 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.
