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

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
