Hi,
Get rid of all the garbages piled up on the system over time. Keep the
registry clean or modifiy it to your needs. Fine tune your system for
what you mostly do with your system. 32 bit OS has max addressing for
memory at 3 GB. If needed go 64 bit or Linux.

Do not EVER use a "registry cleaner." There is nothing a registry cleaner
purports to do that will improve efficiency. For example, the registry is
not searched sequentially, so whether it contains 1,000 entries or 3 million
is irrelevant. The difference to access the proper key between the two is
measured in nanoseconds.

Conversely, use of a registry cleaner can screw up a system beyond repair.
Admittedly, so can a manual modification of the registry, but in this latter
case you at least know what you did.

Next, a 32-bit system has an addressing capability of about 4 GB, not three
(2^32 = 4,294,967,296). Most operating systems snatch some of the RAM for
their internals (i.e. video buffers) so the amount of RAM usable by
application programs is in the neighborhood of 3.1-3.4 GB.
