Have you ever gotten error messages on your Windows system, such as Startupchecklibrary.dll ERROR or Winscomrssv.dll ERROR? If so, don’t worry. Here’s how to completely solve these problems. Essentially, a DLL (Dynamic Link Library) is a series of programs that run under various Windows programs to ensure that games or applications run smoothly.
However, it is now very common that DLL files are easily missing or corrupted in Windows 10. So, if any of the mentioned DLL files are missing or corrupt, you can easily get them working again. However, if you don’t fix these DLL errors, in most cases you will see them and many programs will also be affected.
Most Windows 10 users can find DLL files in the quarantine area of Windows Defender or a third-party antivirus installed. This means that in most cases, security programs can see and evaluate it as a virus or a threat to your Windows system.
So, you may be wondering how to solve this problem. Below are some very simple step-by-step methods to follow carefully. Now, without wasting any more time, let’s get started.
Start analyzing the SFC.
If you want to fix startupchecklibrary.dll not found error manually, it is recommended to run the built-in system file checker (SFC) tool to repair corrupt system files and missing DLL files in Windows 10.
Follow the instructions to run the SFC scan.
- Press Windows key + R, enter CMD> in the Run field and open the command prompt as administrator.
- Now at the command prompt, type the command below and press Enter.
- sfc / scannow
- Wait for the analysis to finish (about 15 minutes).
Reboot the system and see if the missing startupchecklibrary.dll error is fixed. If not, go to the following solution
Run a DISM scan.
If the SFC scan cannot fix the DLL error, run the Deployment and Maintenance Image Management (DISM) tool. This is also a built-in tool that is used when the SFC tool fails to repair corrupted Windows system files.
So, try running the DISM tool and do the following:
- Run the command line as administrator.
- At the command prompt, type the command below and press Enter:
- DISM / Online / Clean-Up / RestoreHealth
- Now wait for the scanning process to complete (about 30 minutes).
- Reboot your computer.

Make sure Windows Security is quarantined in StartUpCheckLibrary.
Microsoft Security keeps the latest threats for Windows 10. Some of the DLL files are also in this section, which may be the reason for this problem. Therefore, you should remove the list by following these steps:
- Click the shield icon in the notification area to launch the Microsoft Defender application.
- In the wizard below, expand Virus and Threat Protection.
- Now click Protection History in the Current Threats section.
- Find the available “quarantined threats” containing DLL files here.
- If so, delete that file and see if the missing issue with StartUpCheckLibrary.dll is resolved.
Manually downloading the DLL file

If you don’t want to go that route, just connect to other computers and copy and paste the file to your computer.
