Does Vista really use up this much RAM?

I just found this CPU meter on the Vista sidebar (Way late to the party, never tried messing with it before).. Anyway supposedly it shows CPU and Random Access Memory usage.. I have 4gb of RAM and according to this meter, just staring at it uses 39-40% of my RAM?

I have a 4850

Vista has a feature called "Superfetch" that keeps applications pre-loaded in memory, so that they load quicker when you want to use them or when they're accessed by some other program (like an antivirus app). The memory *should* be freed if applications actually need to use it. You can also turn it off if you want, if you go to the Services configuration.

Well I guess it depends... I exited from steam, my antivirus, and a couple other things that were on my taskbar and got it down to 34%, still seems like a lot though.. Couth_

Yes it can. I find 1.5GB mostly it uses.
