Recently I found out that my PC are quite slow and sometimes hang, I am surprise with my PC memory usage. IE7 take the highest usage for my pc, no way can a web browser take out the most memory usage for a PC as they are only use for surfing, and my IE7 is without plug-in. It’s clean.

PC's memory usage
Just wonder Microsoft never considering on the memory usage when develop the IE7. I am quite happy with IE7 features but because of the high memory usage, I might switch permanently to Firefox.
Any one is facing the same problem like mine?
