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.
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:
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:

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.
chkdsk /f /r
Updating the Device drivers can also help you fix the PFN_LIST_CORRUPT Blue Screen error. To do so, follow the steps below.
The PFN_LIST_CORRUPT error might also be caused by OneDrive. Thus, you have to try disabling this program to resolve the problem.
“Sending reported error (0×80042109): Outlook cannot connect to your outgoing (SMTP) e-mail server.”
“Out of memory or system resources, Close some windows or programs and try again.” “There is not enough memory to complete this operation – copying files.”These errors are caused by the Desktop Heap limitation when there is no longer enough memory to complete the operation while copying the files. If you encounter any of these errors, you will be guided in this post with the help of some potential fixes that can increase its limit and will hopefully fix this error on your Windows 10 computer. You may try to close all the open windows and programs and then try copying the file again and see if that helps. If not, then proceed to the instructions given below. But before you do that, make sure that you create a System Restore point first. This way, you can undo the changes you’ve made any time in case there are some unwanted changes you want to reverse. After you create a System Restore point, refer to the steps provided below. Step 1: Tap the Win + R keys to open the Run utility and type “Regedit” in the field and tap Enter to open the Registry Editor. Step 2: Next, navigate to this registry key: ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerSubSystems Step 3: Now double click on the DWORD named Windows to modify it. Step 4: Change the values for SharedSection in the Value Data field. It should be in the format of “SharedSection=aaaa,bbbb,cccc”. Note that you have to change the value of “bbbb” and “cccc”. So in case you are using an x86 operating system, set the value of bbbb to 12288 and then set the value for cccc to 1024. On the other hand, if you are using an x64 operating system, set the bbbb value to 20480 and the cccc value to 1024. Step 5: Exit the Registry Editor and restart your computer to successfully apply the changes made. Note: The bbbb value in the SharedSection registry is the size of the desktop heap for each interactive window station while the cccc section of the SharedSection value is the size of the desktop heap for each non-interactive window station. In addition, you must keep in mind that setting the value of bbbb to more than 20480 KB is not really recommended. On the other hand, there is another tool that could help in resolving the Out of Memory error. This tool is called the Memory Diagnostic tool in windows can help resolve the Out of Memory error by checking and automatically fixing any memory-based issues. To run it, refer to these steps:
Error code 0xc000021a occurs when the system is unable to start or there’s a failure in critical system processes. Normally, it would take about several seconds for the system to boot and while on the startup process, error code 0xc000021a may take place to block the system to boot up. Users will get a blue screen of death (BOSD) when this error occurs. When upgrading to Windows 10, be careful; you might encounter other error messages such as error code 8007002c.
There are several reasons why error code 0xc000021a occurs. It is important to have a full understanding of what caused the blue screen of death before attempting to fix the error by yourself. See below for a few common causes:
• Computer malware has infiltrated your device.
• Important files such as Winlogon.exe and Csrss.exe are damaged. Winlogon.exe file is responsible for handling the login and logout processes while Csrss.exe is a vital part of Microsoft Client or Server ‘Runtime Server Subsystem’. Once one of these files is damaged or deleted, a stop error will occur.
• When there are mismatched system files installed or system upgrading process failed or still incomplete.
• Premature unloading of Wbemprox.dll
• Newly installed third-party software is not compatible with the operating system.
• There are corrupted, outdated, or incorrectly configured device drivers.
• There’s insufficient space in the system partition. Once the system partition is full, certain errors such as error code 0xc000021a will manifest.
• Windows registry is corrupted or damaged due to a software or system change. This means there are registry entries that are not cleared after uninstalling an application.
In fixing error code 0xc000021a, you might want to try and manually do so. Manual repair methods can give users effective and efficient solutions, addressing the root problems in relation to Windows error codes. Once the manual repair method is correctly implemented, users will be able to resolve issues immediately. However, there might be instances when a Windows professional is needed. In such cases, seek help from a certified Windows expert or you might want to consider using an automated tool whenever necessary.
