i am using a windows 10 pro system partition on SSD. Machine Lenovo Thinkpad T540p (8GB RAM).
the problem started about half year ago. It is about high windows explorer.exe CPU USAGE.
BUT the strange thing is, that it only happens on some web sites not on all, but on all browsers (chrome - my primary, iexplorer, firefox).
It happens so, that osme pages are opened normally, but others rises the explorer.exe app to 25% of CPU usage, and the page loads about 25 s (yes 25 seconds untill all banners and pictures are shownand the load page corcel icon stops turning).
I tried to boot in safe mode, but the problem is still there.
I tracked the problem down to a ntdll.dll!Rt!UserThreadStart, with stack
I completely turned off indexing of my harddrive, because i am a Android geek so have many bilions of files on some partitions of my HDD.
Tried numerous guides how to solve this problem (i mean explorer.exe high CPU consumption by deleting all icons on the desk, changing timebullet at start to 4 (from 3)...) but nothing helped.
IT only helps to restart the explorer.exe process after i boot the computer, but then (not 100% sure if it is related) after some hours/days of use, i go to BSOD and reboot. Anytime with other error.
But afte the restart of explorer.exe process all three (abov ementioned) web browsers work fluently without HiCUPS of the CPU.
Is there a way to know which program/driver/process/ is causing that or using the ntdll.dll library so, that it eats 25 of the CPU?
Thank you very much
