I use 128 MB RAM,
in system information it is showing available physical memory is
16.96MB. How can I increase the available physical memory.
You should *not* try to do this.
Wanting to minimize the amount of memory Windows uses is a
counterproductive desire. Windows is designed to use all, or
nearly all, of your memory, all the time, and that's good, not
bad. Free memory is wasted memory. You paid for it all and
shouldn't want to see any of it wasted.
Windows works hard to find a use for all the memory you have all
the time. For example if your apps don't need some of it, it will
use that part for caching, then give it back when your apps later
need it. In this way Windows keeps all your memory working for
you all the time.
Also note that 128MB is too little RAM for decent performance in
Windows XP. How much memory you need depends on what apps you
run, but almost everyone needs at least 256MB for decent
performance. For some people, for example those who edit large
photographic images, more than 256MB--even much more--can be
required for good performance.
