Windows 10 disk load 100% caused by ekrn.exe

Question

Recently I updated my PC from Windows 7 to Windows 10 and everytime I turn it on for 20-30 minutes is extremly slow. Task Manager shows disk at 100%. I checked why and I found out that is caused by ekrn.exe and other process but this one looks the main reason that slows my PC. I'll show you some of these processes (there are many more). I've cleened registers with Ccleaner. This never happend with Windows 7. Can you help me?

Answer 1

Looks like Microsoft made some changes that conflict with certain versions of the product (see here). Try uninstalling & reinstalling the software to see if the helps. I've seen allot of different Anti-Virus programs behave strangely after OS upgrades.

Worst case scenario, you can always backup your data, and do a fresh install with your Windows 7 key. http://www.howtogeek.com/224342/how-to-clean-install-windows-10/

Answer 2

This process usually belongs to ESET Antivirus. Use this uninstaller here: http://support.eset.com/kb146/?locale=en_US to uninstall everything ESET-related.
