    Windows 10 High CPU usage Fix

    Hi i'm writing here to post an answer to the Windows 10 High CPU issue that i found and also ask the Microsoft Team why does this occur so i can understand it.

    So to the answer; my CPU usage all of the sudden became high over the last few weeks, i'd tried to trouble shoot as others and Microsoft had suggested, though nothing worked. Microsoft has suggested to create a new account and transfer files which also proved
    fruitless after transferring files as explorer.exe again consumed high CPU usage. It was just luck that i stumbled across the solution in one of these threads that linked to an answer from 2011.

    Firstly i just want to state that i did download process explorer and it had revealed it was explorer.exe causing high CPU usage and not a .dll file.

    The solution:

    Broken icons on desktop. That's it. After reading The Solution i found i had 3 desktop files with no
    icons at all. I deleted these three files (two shortcuts, one PDF) and instantly the CPU usage by explorer.exe dropped from a constant 38-40% down to 0.2%

    I was wondering if someone or Microsoft might be able to clarify what causes this to actually happen?

    Thank you

    Windows 10 Display Blinking with High CPU

    After upgrade to Windows 10, experiencing flashing display and high CPU.

    • At initial logon screen everything is normal - wall paper and logon screen display with no blinking
    • After logon, fan starts as CPU usage spikes, cursor is accompanied by the spinning blue circle
    • touchscreen does not respond to swipe to access Recovery/Safe mode for reboot
    • able to get to Task Manager and Perfmon to see high CPU usage and explorer.exe is suspended
    looking for suggestions on how to either fix or roll back to Windows 8.1
