DCFWinService.exe is an important part of Disk Cleanup Utility (also known as Disk Cleanup), which you use to clean up temporary files and free space on your hard disk. If it gets stuck consuming high amounts of system resources, it could cause problems with your PC. In this article we’ll show how to quickly resolve this problem.
DCFWinService is a service provided by Microsoft Corporation. It provides various functions related to the Direct Connectivity Framework (DCF), including managing connections between devices and applications, providing device discovery functionality, and performing security operations.
It uses a lot of resources when running on Windows operating systems. When the number of clients increases, so does the amount of memory used by the process. As a result, the computer slows down and becomes unresponsive.
You may try to stop the service manually. However, stopping the service may cause problems with some applications. For instance, some applications rely on the service being active to function properly. To avoid these issues, you must find another solution.
We recommend that you update your drivers. We also suggest that you install the latest version of the driver.
