compaq sr5440an (new zealand+ australian model)

hi all.by default this model pc displays utilities such as adaware,spy
bot etc in very small (i think it could be described as) type size.i
know i can increase the dpi size for the desktop icons,which i have
done,but this does not make the "type size" any larger in the utility
programs.is there a registry tweak or a fix for this? also web pages
need to have "zoom" adjusted every time to about 125-150% as zoom
adjusted to 125 or 150% apparently can't be made default size.hope you
can help,as it will make think twice when buying my next hp-compac
product. thanks bob.
