In Windows 11, when copying files, CPU usage abnormally approaches 100%.

Question

In Windows 11, when copying files, CPU usage abnormally approaches 100%.

When copying files in Windows 11, CPU usage is abnormally high, nearly reaching 100%. The task manager shows that all processes occupying the CPU are magnified by tens of times. After logging out or restarting the computer, it returns to normal for a while, but after about ten minutes of copying files, the abnormal usage reoccurs, with speeds only reaching around 200MB/s.

I have ruled out the hard drive problem and have reinstalled the system multiple times, but the issue still persists.

When everything is normal, the speed is around 2GB/s, and the CPU usage of processes, as shown in the screenshot, is magnified by tens of times. For example, if Chrome is stably using 1% of the CPU, when I start copying files, its usage will be raised to 30% or even 40%.

Answer 1

Hello,

Some people may met the same high cpu issue when copying file.

Based on my search, some information below about this issue.

Microsoft finally fixes annoying Windows 11 file copying bug | TechRadar

Microsoft Acknowledges High CPU Utilization Bug in Windows 11 File Explorer | Tom's Hardware (tomshardware.com)

So, I suggest that we'd better wait for next security update to fix the system file.

Best Regards,

Hania Lian
