When using IE on certain sites the browser with seem to free and star using 50% CPU and when looking at Process Explore I see that it's because of iertutul.dll, also if I run IE in no addons mode, the problem is gone. The thing is I don't know which addon is causing the high cpu usage. Anyone experienced this?
microsofts words (not mine) iertutil.dll is a Run time utility for Internet Explorer from Microsoft Corporation belonging to Windows® Internet Explorer iertutil.dll is a system process that is needed for your Windows system to work properly. It should not be removed. it is concidered to be a CPU intensive process ,and can at times hog the system. google it there are workarounds ,I believe if you look hard enough.
disabling the divx web plugin reduces the cpu usage a bit but It shouldn't effect sites that have no divx content....
returned to ie, because I liked ie9. The only addons I wanted were adblock & flashblock and they available for ie now.
