Hi, I clean installed from USB flash drive Windows 10 AU aka version 1607, have been experiencing high CPU usage with certain programs,
Troubleshooting done:

-SFC/scannow says Windows Resource Protection did not find any integrity violations
-Disabled firewall and on-access scanning in Bitdefender total security 2016

-User Account Control turned off never notify
Programs affected by high CPU usage:
-Microsoft Edge
-Chrome
-Firefox
-Adobe Reader
-iTunes
Symptoms started upon connecting my laptop to the Internet after installing latest version of Intel wifi driver. All Intel drivers are taken from Station-Drivers - NEWS
Intel drivers for chipset, management engine interface, dynamic platform and thermal framework, Intel HD graphics were injected into install.wim on another desktop computer before making bootable USB flash drive using Rufus.
Upon opening above-mentioned programs, CPU usage spikes to 70-100% and fluctuating up and down, for Microsoft Edge it occurs only when visiting some websites such as Google or Microsoft sites.
Chrome, Firefox, Adobe Reader, iTunes, are all latest available versions, CPU usage shoots to 100% once I open them up causing program freeze and the only way is to end task in task manager.
List of installed programs:
-Adobe Reader
-Bitdefender total security 2016
-Chrome
-Firefox
-iTunes
-Nvidia graphics driver 368.81
