Hey Aowl. Guess what? You might remember in that big thread on how my Monitor Dll Injections (MDI) issue returned after I re-installed CPF 2.4. At first I thought it was updating my video decoders followed by 2 reboots (with the second one being the next day) that resolved it. But I was wrong. I knew something wasn't right because usually it's only 1 reboot that fixes things. Anyway, I left MDI off for a week. I turned it back on today just for the fun of it and tested that site again with cmdagent.exe at 0% CPU

. This lead me to another contemplation of the reason, and that is CFP requires
time to learn about a system. My Component Monitor list is also apparently bigger now and it feels like it's almost complete. Probably during the midst of this learning process, at the beginning of a new installation, MDI was interfering...If I turn component monitor on, my peak is now much lower to 43% (like on your system).
I didn't post this in the other thread because there's no definitive confirmation. If this successfully continues for another week with MDI on, then my theory will be correct.
