To remove the StartupCheckLibrary.dll error, first download Autoruns:

https://live.sysinternals.com/Autoruns.exe

  • Run Autoruns.exe as administrator.
  • In the Filterbox up top Enter: startupcheck
  • You should see a Task Scheduler entry:\Microsoft\Windows\Application Experience\StartupCheckLibrary
  • Right click on this entry and Delete.

...and that's the end of the error.

BTW Ignore any advice that recommends restoring this dll from quarantine. It's a CoinMiner and you really don't want it!

    I suggest you to follow this guide first to solve your issues with Windows Update and Windows Security: https://www.youtube.com/watch?v=ln1B8yB1YHI

    My PC was unable to update Windows or install anything (languages for example) from Microsoft Store. Defender was basically missing and firewall was down. I had a blank screen when I went to check the protection in the settings.

    After you've fixed that, you'll be able to update your system and get Defender back to work. I believe that after that you will be able to go to Defender and allow startupchecklibrary.dll.

    Gday Andrew, 

    Currently I have the issue where not only is the startcheckuplibrary missing but the winscomrssrv.dll file too. 

    These seem to have both come at the same time after I updated to a later windows update. I updated to the newest version of windows because I ran into error codes when trying to access the Microsoft store. A kind gentleman from Microsoft helped me through that.  

    I have read through this thread and tried what was recommended by yourself and others. 

    All of the command prompt scripts were run in admin mode but none seemed to have worked. 

    I have also checked through my windows security tab in search of a dll file in quarantine, but found none. 

    Kind regards, 

    Lawrence
