The increase was seen in the ehshell and ehtray processes. Not even playing anything back - only opening wmc. I had media center studio and media browser plugins installed also. Any issue with using these plugins together? Anyway - I've since reinstalled w7 because media center studio was causing issues. I'll let you know how it turns out this time around.
Thanks for the fast reply.
Started with a clean install of 7 and only imported this plugin - same issue with the cpu. I've attached a pic of the running processes when wmc starts - ehshell.exe runs steady at ~40% with this plugin while without the plugin I see ~5%.
Thanks for the information. The background app monitors for playing media and allows the resume feature to work. It definitely shouldn't be using that much cpu. I'll take a look at my code and see what I can optimize.
