How to Fix: COM Surrogate Issue 2023 [Updated]

If you are a Windows user, you may have come across the term “com surrogate” at some point. It’s not uncommon to see this process running on your computer, but it can sometimes cause issues that leave you scratching your head. In this article, we will explain what com surrogate is, why it might be using high CPU, and how to deal with any problems that arise.

What is Com Surrogate?

Com surrogate is a process that runs on Windows computers to handle DLL files and other COM objects. Dynamic Link Libraries (DLL) are files that contain code and data which can be accessed and shared by several programs simultaneously. When a program needs to use a DLL file, it can request access to the file through the com surrogate process. This helps to prevent conflicts between programs that may be using the same DLL file simultaneously.

Why is Com Surrogate Using High CPU?

It’s not uncommon for the com surrogate process to use a significant amount of CPU resources. This can happen if there are multiple programs running on your computer that are all requesting access to the same DLL files. When this happens, the com surrogate process may need to create multiple instances of itself to handle the requests, which can cause the CPU usage to spike.

Another possible reason for high CPU usage by com surrogate is that there is a problem with a specific DLL file that is causing the process to malfunction. In this case, you may notice that the com surrogate process is using a lot of CPU resources even when there are no programs running on your computer.

How to Deal with Com Surrogate Problems

If you are experiencing high CPU usage or other issues related to the com surrogate process, there are several steps you can take to resolve the problem. The first step is to identify which programs are using the com surrogate process. You can do this by opening the Task Manager and looking for the process name “dllhost.exe”. This process is the com surrogate, and you can see which programs are using it by clicking on the “Details” tab and looking for the “COM Surrogate” column.

Once you have identified which programs are using the com surrogate process, you can try closing them one by one to see if the CPU usage decreases. If this doesn’t work, you can try disabling thumbnail previews for certain file types, as this can sometimes cause problems with the com surrogate process. Launch File Explorer and navigate to the “View” tab to perform this action. Then, select “Options” and proceed to “Change folder and search options.” In the “View” section, tick the box beside “Always show icons, never thumbnails” and click on the “Apply” button.

If none of these solutions work, you may need to troubleshoot specific DLL files that are causing problems. To do this, you can use the System File Checker (SFC) tool, which can scan your system for corrupt or missing files and repair them automatically. To execute the SFC tool, launch the Command Prompt with administrative privileges and input “sfc /scannow” in the command line.

What is Com Surrogate in Windows 10?

Com surrogate is a process that is present in all versions of Windows, including Windows 10. If you are experiencing problems with the com surrogate process on Windows 10, the solutions outlined in this article should still be applicable.

In conclusion, com surrogate is an important process that helps to prevent conflicts between programs that are using the same DLL files. While it can sometimes cause high CPU usage or other issues, there are several steps you can take to resolve the problem. By identifying which programs are using the com surrogate process and troubleshooting specific DLL files, you can keep your system running smoothly and avoid any performance issues.
