when i use the internet explorer then the proccess iexplore keeps growing in it's memory size, only when i close all internet explorer windows it disappers..
Well duh. All programs continue to grow in memory size (when they are doing different, non-regular operations). When you close Internet Explorer obviously it disappears, IEXPLORER.EXE IS Internet Explorer.
Also, I recommend you download Mozilla Firefox, it's so much more efficient and safer. Honestly, you should.
Really? I never heard of that, what is that, a Vista feature. I never really care about my Windows computers, they're just used to play video games and read crap. I could care less what happens to them, haven't been updated since I installed Windows over it last (whatever is on the CD, is what it gets).
