Question

Windows 10 1809

Windows cannot load the extensible counter DLL «C:\WINDOWS\system32\sysmain.dll» (Win32 error code The specified module could not be found.).

All replies

This means that you either do not have the correct DLL or are missing a DLL (sysmain.dll).

So we’d better copy this dll file from other same system version machine and paste it to this machine to replace sysmain.dll. The file location is C:\WINDOWS\system32\sysmain.dll.

Then we could use command to registry this dll file.

I have similar issue. I checked the sysmain.dll and it is present in the system32 folder and properly registered.

Any other ideas what can cause this issue?

Same here, I also have sysmain.dll present in the system32 folder and get the same error error:

It’s been half a year and still no answer from Microsoft?? What’s the point of this forum then?

I have the same problem and yes these files are present on my system. Chkdsk c: /f didn’t find anything interesting to fix

I have similar issue. I checked the sysmain.dll and it is present in the system32 folder and properly registered.

Thank you for writing to Microsoft Community Forums.

I understand that you’re facing issues with Blue Screen on your PC, and I certainly appreciate your efforts in trying to resolve the issue.

We will certainly look into this for you.

For further clarity on the issue, please respond to the questions below:

1. Which build version of Windows 10 are you using currently?
2. Are you aware of any changes made to the PC prior to which you weren’t facing this issue?
3. When exactly do you receive the Blue Screens?

Meanwhile, I would suggest you to refer the article Troubleshoot blue screen errors and see if that helps.

You can also try booting the PC in Safe Mode and see if it crashes. Refer the article Start your PC in safe mode in Windows 10

If the PC is not crash in Safe Mode, then try booting the PC in Clean Boot and see if the PC crashes. Refer the article How to perform a clean boot in Windows

Performing a clean boot will start the computer with minimal set of drivers and programs, to determine whether a background program is causing the issue. Some of the Startup programs will not load after performing a clean boot on the computer. However, that functionality will return when you reset the computer to start normally after finishing the troubleshooting.

If the PC doesn’t crash after performing Clean Boot, then please refer the section How to determine what is causing the problem after you do a clean boot to identify the root cause of the issue.

Note: Please refer the section Reset the computer to start normally after clean boot troubleshooting to boot the computer in to normal mode after troubleshooting

However, it would be great if you could upload the files on OneDrive and share the link to us.​ If we can analyze the dump file, we may be able to narrow down the cause of the error. The Dump files are located in C:\Windows\MiniDump folder.

Let us know if you need any further assistance, we will be glad to assist you.

As the following Microsoft official article says, it is no perfts.dll file loaded in Windows server core.

Try to run the following command line as administrator to repair corrupted system files.

DISM.exe /Online /Cleanup-image /Restorehealth

When I ran Dism.exe/online/Cleanup-image /Restorehealth

it stop with errors at 89.8%

Does the issue bring any affection to your environment and production?

Try to check if perfts.dll located in C:\Windows\System32 on your server core.

We could copy another one from same system version device to replace it.

Also we should make sure your account have full privilege for the following registry key.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSSQLServer\Performance]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSSQLServer\Performance]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSSQLServer\Performance\Library]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Perflib\009\Counter]

Here is an official article similar with your issue, please check on your side.

If it will not bring any affection on your production, I recommend to miss it as it is safe to use your system.
