Repost: Slow Internet Explorer Version 8 on Windows Server 2003

[Guest BenboFarkern]

Up until a month ago IE8 was working fine on my Windows 2003 server – which I use as a development machine - but something is now affecting the performance of IE8 making it almost unusable, and forcing me reluctantly to use other browsers such as Chrome.

Perhaps someone can make sense of it all?

For example: (a) Google’s predictive search drop down causes IE8 to almost freeze up, particularly if the backspace key is used to make corrections; (b) right clicking over a page link can often take half a minute before the right-click menu appears; © moving through IE8 page tabs is very slow - or the tab refresh is very slow. Task Manager indicates high CPU usage, so IE8 is busy doing something but it’s not obvious what.

I have checked for viruses; and Fiddlerindicates there is no other browser internet activity. I’ve also re-installed IE8, and run it using In-Private options to reduce activity.

Output from Process Monitor Sysinternals utility shows successive groups of messages as follows:

iexplore.exe 148 RegOpenKey HKCU\Software\Classes\TypeLib\{3050F1C5-98B5-11CF-BB82-00AA00BDCE0B}\4.0\0 NAME NOT FOUND
