Memory usage over 90%

Recently I noticed that the memory monitor always shows more than 90% of
memory are used. My system has 1.5G memory installed. The running
applications include a firefox browser window, a word file, an eclipse
editor, thunderbird, and live messanger. How come 90% are used? I check the
processes in task manager. The total used memory doesn't add up to 90% of
1.5G. What's wrong with my vista?
BTW, I am using vista business on THinkpad T60p.

Free memory is wasted memory.. Vista uses as much as it can, freeing up
memory if required for a newly started process or program..

What you are seeing is normal, and a good thing..

IGNORE IT!!!!!
Vista uses memory(ram) to simulate an L2 cache. That is the part of
your cpu that reads ahead and behind trying to guess what you are
going to do next. Over the long run Vista is faster as a result. It
will release as much memory as a program needs to run and then take it
back when the program no longer needs it.

Thanks for the replies. But I never see vista release the memory. After it
goes up over 90%, it will stay there forever until I restart the machine. Is
that normal?

Normal. I have 2GB of system memory and right now I am showing 4MB free. My
system is using 623MB and the rest of the 1377MB is used for other programs
I may use later.

You are missing the point. Vista will load up your apps in RAM just like XP
and any other OS. Vista will also start filling up the ret of the RAM with
stuff it thinks you might need soon. If another app comes along and wants
more memory then some of this will be freed to allow the app to run.

In effect you still have all you spare RAM, it is just being used like a
cache, but will be freed up instantly if anything needs it. Trust me, it is
a little strange to get used to at first, us Windows users are used to
trying to keep RAM free, but Vista really does not work like that.

To put it another way, if you wanted to keep RAM empty then why bother
installing it? It is there to be used.

YES it is the way it is supposed to be.
