I've had a look at the threads relating to explorer.exe with process explorer and there seems to be one thread causing the high cpu usage.
When I kill the thread, nothing seems to go wrong, it simply appears to run as it should. Any thoughts on this?
Do you have "Rising AntiVirus 2011" installed ?
Quick search points that "combase.dll" is part of that AV
Other things are saying it is part of a runtime in win 8, maybe update dot net and runtime visual C++ etc ?
