Here is a helpful hint I discovered myself so I thought I share it with you. After installing IE 9 and using it for about a week I went back to Firefox 3.5.6. then eventually to FF 4.0. So I never went back to IE ever again. But for some odd reason ielowutil.exe would magically appear. I didn't think much of it at first. So one day I was determined to get to the bottom of this mystery. I opened up my trusty Process Hacker and explored everything about ielowutil.exe. The parent program of course is IE. But the fact that I never opened IE made it even more odd. So I did some research for about an hour and came up with nothing. So I went into Process Hackers settings and enabled all the system tray features which basically tells you who started who,when and where. I sat and watch my laptop for about an hour at idle. When ielowutil.exe started it was triggered by Feeds and Web Slices. I was like .............."What?". So I went into internet options\content\feeds and web slices\settings. In there I unchecked "automatically check feeds and web slices for updates". I also unchecked everything else in there. Presto................Problem gone. So exactly what was going on? Well it turns out that ielowutil.exe is a prefetcher for feeds and web slices. That was about 2 weeks ago and ielowutil.exe has never mysteriously appeared on its own again. Hope this helps some members and also you can learn how Process Hacker can be used as a diagnostic tool.
