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.

 

ntoskrnl.exe causing high cpu usage

It is completely random when it causes high CPU usage. It dosen't (as far as I can see) take up much memory, it just causes high CPU usage.

It spikes to about 20 - 90 % and stays like that for a second or so and causes my computer to freeze during that time. It can happen often, like every 5-10 minutes and sometimes it can go about 30 minutes. I do not recieve any error when this is happening.

 

WIN10 1703 update cause Explorer.exe high CPU usage

I am using Surface Pro 3 (i5, 8G RAM)

After WIN10 v1703 update, Windows Explorer uses ~30-40% CPU.

If I uncheck "Show thumbnails instead of icons" in the Performance Options, the CPU usage of Windows Explorer reduces to ~0%

Any suggestion why showing thumbnails cause so high CPU usage in v1703?

Thanks!
