Windows 10: Windows explorer runs slow/freezes often taking up high CPU usage when idle

System performance, especially when running windows file explorer, is slow to respond or freezing.Trying to navigate the file system has been slow even when all programs are closed.Investigating in task manager I noticed windows explorer can run as high as 20% even when idle.I have run system file checker and re-imaged the computer, with brief moments of better performance,but the problem consistently returns.System Information_____________________________________________OS Name Microsoft Windows 11 EnterpriseVersion 10.0.26100 Build 26100OS Manufacturer Microsoft CorporationSystem Manufacture

Brevity can be a virtue but it can also be counter-productive.

High CPU Usage at Idle

You also might want to take a look at Dynamic frequency scaling (also known as CPU throttling). Under Windows 10, the CPU is throttled back to 5% when the computer is idle and then gradually goes back up depending on work load. Perhaps the minimum and maximum percentages have been somehow altered from their defaults of 5% to 100%. Or on the Advanced Settings Tab, it might be set to High performance.

To check, follow this path: Control Panel > Power Options > Change plan settings > Change advanced power settings.

Open the pull-down box and select "Balanced". On the list below, expand Processor power management > Minimum processor state.





Click on the word "Setting" and enter your desired percentage. The default is 5%. Note that if "High performance" is selected, the percentage is bumped up to 100%. This may be why your CPU is running fast. You can now retest using CPU-Z.
