  • Question

I followed some steps from another persons questions answer to access msconfig and disable features and restart, no resolution also tried boot in safe mood but yet it has extremly high CPU.

    How about you problem now?

    What did you do before this problem?  Did you install update, software or driver? You mentioned that when you boot in safe mode, The problem is still exiting, So I want to confirm whether the explorer.exe occupy high CPU and memory usage as soon as you boot in system, or other conditions?

    Please provide more details as you can.

    You can use Process Explorer and DPC Latency Checker tool to help you troubleshoot the high usage of CPU.
