I'm not having many problems with explorer.exe leaking into memory, but it is constantly using up all available processor usage, any ideas why it would be doing that? I've minimized the side bar, and I'm running BOFH's Leak Fix prog to control explorers leaks.

BOFH's leakfix just pushes the memory leak into Virtual Memory (page file).. you can see this by enabling the VM size column in Task Manager.. sooner or later itll eat CPU percentage.

Minimizing the sidebar does nothing, you need to turn it completely off, and then run the explorer fixes and follow the guide at http://www.nextl3vel.net/Chris123NT/4074/LHGuide.html
