How can I reduce the 20–30% CPU usage caused by Extended Copy Utility during Windows 11 startup?

After the system boots up, I noticed a process named “Extended Copy Utility” (located in the C:\Windows\WinS directory) consistently consuming 20–30% of CPU resources, which is affecting system performance. I need to understand the specific function of this process and how to effectively reduce or limit its CPU usage.

    Typically, a process with a name like “Extended Copy Utility” could be designed to manage file copying, backup, or data transfer tasks. It might be part of a legitimate utility provided by certain hardware manufacturers or third-party backup tools.

    Sometimes, it is part of built-in Windows features or third-party backup software that manages data integrity during copying processes.
