Did you ever get to the bottom of this, as I have a number of machines that are doing exactly this. dcomlaunch and plug and play services taking up CPU (not so much a memory problem - and I know there is a KB fix for that which didn't work)
I've disabled windows update, uninstalled software, checked for malware, sfc'ed, reset WMI repositories, unplugged hardware... and I just cannot get the bottom of it.
Checked with the sysinternal tools and I am getting nowhere...
