That GUID maps to the "Shell Hardware Mixed Content Handler", which is a COM handler that needs to run as "Interactive User", meaning run in a logged-on user's session (that's you
). The reason it needs to run in the context of a logged-on user is that it's actually the Autorun handler (enabling Autorun on my own Windows 7 box causes the same process to be spawned).
If you don't want to see it, go into the control panel and disable Autorun. Otherwise, it needs to run for Autorun to work properly.
