  2. WIN10 1703 update cause Explorer.exe high CPU usage

    Hi,



    Glad you reached out. First, we would like to know if Explorer.exe
    is the only cause of high CPU usage. Because the common cause of high CPU usage are the following:

    - Windows 10 Memory leak after the update.

    - Driver incompatibilities after the update.

    - Multiple startup applications





    We'll be waiting for your update.

    Windows 10 System High CPU Usage ACPI.sys

    Exactly the same problem with Macbook Pro 15 2014 11,2. I have the same thread ACPI.sys and the only solution I founded is going into sleep mode and back. I suspect too the drivers.

    Please update if you have a better solution !

    Thanks

    Windows 10 System High CPU Usage ACPI.sys

    I had indeed permanently a MicroSDHC card in the Surface 3 Pro.

    Unfortunately, removing it does not solve the problem for me: even with the card removed, I keep getting randomly the "System and Compressed Memory Service High CPU Usage" symptom, and more specifically in ACPI.SYS
