Easy fix for winscomrssrv.dll: There was a problem starting winscomrssrv.dll

A friend of mine had an error at the startup of his computer. RunDLL There was a problem starting winscomrssrv.dll. The specific module could not be found.

What happened before

Previously he’d been a victim of a trojan virus. His antivirus program quarantined three files from C:\Windows\System32:

  • winscomrssrv.dll
  • startupchecklibrary.dll
  • winlogui.exe

Afterwards, his pc was running fine and smoothly. Windows Defender did not find any threats. Still he got these RunDLL module errors at startup.

How to fix There was a problem starting winscomrssrv.dll

The winscomrssrv.dll and startupchecklibrary.dll errors are definitely the dreg of the malware that was present before.

I was sure all threats were solved. I only needed to remove the references to the (missing) DLL files. Sysinternals Autoruns is a great free lightweight tool to help you with this.

Detailed steps to fix winscomrssrv.dll

  1. Download and unzip Autoruns from https://docs.microsoft.com/en-us/sysinternals/downloads/autoruns
  2. Rightclick the downloaded Autoruns.exe and choose Run As Adminstrator
  3. In the Filter box, type winscomrssrv
  4. View the result. Any ‘File not Found’ image paths, are save to delete.
  5. Do the same for startupchecklibrary. Any File Not Found results can be safely removed.

Community additions

From the comments below, I’ve learned some people still have the error after deleting winscomrssrv.dll and startupchecklibrary.dll.

I found out that there’s an additional scheduled task, named srvhost, that may lead to the error message. To fix, do the following:

  1. Run Autoruns.exe as administrator.
  2. In the Filterbox up top Enter: srvhost
  3. You should see a Task Scheduler entry: \Microsoft\Windows\WDI\SrvHost
  4. Right click on this entry and Delete.

You may also see the entry winlogui in Autoruns. As far as I’m informed, this entry should not be run at startup. On my pc at least, entry winlogui is not present. If you’re getting an error about winlogui, you could try to delete it. I think it won’t harm. However, I don’t know what the consequences are.

Final note

Malware often leaves traces behind. Even when the malware is removed by your antivirus program. However, errors like “The specific module could not be found” are not always caused by malware. An upgrade of Windows 10 or uninstallation of 3rd party software may also leave traces. A great example is Logitechs logilda.dll

In most cases, Sysinternals Autoruns.exe may help you remove these kinds of startup errors.

Hi. I’m having the same problem.

After downloading this will it resolved all pop ups like startuplibrary.dll???

Mr. Rogers

Please note the typo in Detailed Steps:
3. In the Filter box, type winscomrssv > winscomrssrv
(This typo also appears in a couple of article and section headings.)
Great program nonetheless!

Hi, i successfully deleted startupchecklibrary. Unfortunately, i can’t find winscomrssrv in the autorun, any fix to that?


I also can’t find winscomrssrv.dll in the autorun, but I’m done with startupchecklibrary, any ideas?


I also couldn’t find winscomssrv so i deleted srvhost and it worked! Thanks a lot!


Great! Thanks!!!

Pedro Clement

I’ve tried everything…including reinstalling Win10 (keeping apps and docs), and when finished the new installation, those pop up appaired again!!! I don’t know what to do…

Pedro Clement

Yes, I did. In the first search I got some files highlighted in yellow, but none of the *.dll in question. I deleted all and the problem continues after restart…

Pedro Clement

I’ve never installed third party antivirus, and the Windows Defender don’t show any quarentine file.

Pedro Clement

Well…it seems to be fixed…finally…
First step, using Autoruns, then, Task Scheduler. I searched for those tasks and their search related triggers. And I stopped them.
After restart, no pop-up appeared and no fkng “error sound”…

Maja Rocha

This helped a lot. Thank you so much!


Everytime i run it as an administrator, I cant see the winscomrssrv file. Please help


I get this error on startup yet when I search for the three terms in the filter box i don’t get any file


Same, still can’t get rid of it


Hey guys, came across this thread and just wanted to say a huge thank you to everyone on it. I was having this same issue, followed the instructions and it worked! 🙂


Finally resolved that pesky winscomrssrv.dll issue — note that it somehow became ‘hidden’ or un-findable after Running as Admin. Deleting the WDI SrvHost removed the annoying error thing at the end though.


Thank you so much!!! I can finally locate the winscomrssrv.dll. It just doesn’t show in Autoruns run as admin.


Wow. That actually helped. BIG thanks!
