COM surrogates are an essential component of Windows operating systems. They are used to host dynamic link libraries (DLLs) and provide extension services. Without COM surrogates, it is impossible to run applications written in Microsoft Visual Basic for Applications (VBA), Microsoft Excel VBA, Microsoft Access VBA, Microsoft Word VBA, Microsoft PowerPoint VBA, Microsoft Outlook VBA, and many other languages.
A COM surrogate provides a set of functions called COM interfaces. These interfaces allow COM objects to communicate with each other without having to know about the implementation details of the underlying object. For example, you could write code that creates a file in a specific folder and use the CreateFile function. However, you don’t know how the file system works; you just want to open a file. A COM surrogate allows you to work directly with the file system interface without knowing anything about the implementation.
The COM surrogate is responsible for marshaling data between the application programming interface (API) and the native API. This makes COM surrogates very powerful because they can be used to bridge the gap between different APIs. COM surrogates are often the most efficient way to implement interop solutions.
Microsoft introduced COM Surrogate in Windows 8.1 Update 2. This feature allows programs written for 32-bit versions of Windows to run on 64-bit systems without recompiling. However, some users reported that COM Surrogate causes numerous problems on Windows 10. These include slow performance, system crashes, and even data loss.
Users report that these problems tend to occur after installing new software. They also say that there are multiple ways to fix these issues. One way is to disable the COM Surrogate feature. Another option is to use the Microsoft Fix it tool, which can repair registry errors, restore files, and reinstall applications.
There are several ways to solve the issue. For example, you can delete the COM Surrogate folder manually. Follow the steps below to fix this issue.

Be sure to update your antivirus program
In recent months, there has been much talk about how Windows 10 PCs are affected by malware. This is because Microsoft has introduced some security measures into the operating system. These changes include the use of a feature called ComSurf, which is used to make sure that applications cannot access memory locations outside of their allocated space.
However, according to reports, this feature can sometimes lead to errors generated by antivirus programs. In turn, this causes problems with the operation of other programs. As a consequence, you might see strange behavior on your computer.
This problem seems to affect only certain antivirus products. For example, Avast and Bitdefender seem to work fine, whereas Kaspersky and ESET don’t. However, the issue does not occur with every antivirus program out there.
The best way to resolve the problem is to update your antivirus software. Then, restart your computer and try again. If all else fails, you could switch to another antivirus product.

Perform an SFC scan
The System File Checker or “SFC” is an easy-to-use command prompt utility that checks the integrity of system files. If it finds corrupt files, it replaces them with a good version of the file. This is helpful because many times, you might find out that one of the system files is damaged, and replacing them with a good copy helps fix things.
To check for corruption, simply open Command Prompt and type in sfc /scannow. You can see the list of corrupted files. To replace them with a good copy, just type in sfc /rebuild.
Run a virus scan with antivirus software
If your computer is infected with malware, it may cause high CPU usage. This problem is called COM Surrogate’s high disk usage. In this case, the antivirus program cannot work correctly because it needs to load the whole file into memory. However, there are some ways to fix this issue. We recommend you use one of these methods to solve the problem.
1. Press Win + I to open the Windows Settings window.
2. Click the Start button and type “Windows Update.” Click OK to start the update process.
3. Select the option “Scan my PC now for potential issues.”
4. Then select the option named “Install Updates Automatically.”
5. After scanning completes, restart your computer.
A clean boot should be performed
When you meet COM Surrogate high disk usage during your computer startup, consider performing a Clean Boot.
This can troubleshoot some Advanced Windows problems.
1. Press Win+R to open the Run dialogue box.
2. Type MSConfig and hit Enter.
3. Click the Startup tab.
4. Select Show hidden processes.
5. Uncheck Hide processes belonging to Microsoft.
6. Hit OK twice.
7. Restart your system.
Remove recently installed drivers
Drivers are usually installed automatically during the installation process. However, sometimes, even though a driver is installed, the system will report an error or display messages about missing drivers. This happens because some drivers are not compatible with Windows 10. To make sure you don’t miss anything important, we recommend checking Device Manager. You’ll see there what device needs to be updated or replaced. If you encounter such errors, uninstall the latest drivers you’ve just installed.
