Dang. So I can't use it at all for anything.

Why not upgrade to Windows 7 64-bit? What is it that you have that can't
run on it?


Several points he

1. An upgrade from 32-bit Windows to 64-bit Windows is not possible.
He would have to do a clean installation of 64-bit Windows to get
there.

2. He couldn't even upgrade to 32-bit Windows 7. An upgrade from XP to
Windows 7 is not possible, and again, he would have to do a clean
installation.

3. He's presently seeing 2.5GB of his 6GB. It depends on what
applications he runs, but it would be very rare for anyone running XP
with 2.5GB to see any improvement by having more RAM available.

4. It's similarly unlikely that he would see any improvement in
performance by running Windows 7 with 6GB over Windows XP with 2.5GB.
There are, in my view, several good reasons to go to Windows 7, but
that's not one of them.
