I agree : there is no benefit in upgrading your
current OS .
You may be interested in reading something about
WOW64 & behaviour of 32bit based programs on WINDOWS
XP x64 AMD edition .
I was corious...so i installed it & now i advise you
against trying it : it will be a waste of time , as
you'll decide to come back , thus reformat 2 times in
one day .
Anyway , it's your choice .
You could also be interesting in evaluating this OS ,
which is 32bit based :
I would like to know in advance if i try to install xp pro 64 over a xp pro when booting from the xp 64 cd if i will be prompted upgrade or full installation ? if so do you recommend an upgade or a clean install, this is a new machine with win xp pro but it has AMD 64 PROCESSOR on it, so is capable for 64.
Thanks in advance
