I recently bought a new computer pre-installed with Vista Ultimate.
However, the version installed on the computer is the 32 bit version,
not the 64 bit version. Does anyone know if there is there a way to
change it to the 64 bit version?

As I understand Vista Ultimate (32 bit version), I will only be able
to install up to 4 GIGs of RAM even though my motherboard can handle
up to 8 Gigs of RAM and my processor is a 64 bit processor. Is there a
way I can install Vista Ultimate 64 bit version for free, by using the
Vista Ultimate Windows Activation key that came with my new computer?

Any information will help.

thanks!
