Default 32 bit or 64 bit ?



My wife has new win 8 machine (HP) .
How do I determine whether it's 32 bit or 64 bit?
OR, are all Win 8 machines 64 bit?

I have no documentation that specifies and
internet sites don't say anything but "Windows 8".

Control Panel : System, then look at the declaration there.

In a world with Start panels, you can type "Control Panel"
in there. When the Control Panel appears, look for the setting
to change to Small Icons. Then, the view will be big enough,
to show all the control panels. Then, select System from there.

In the examples here, you can see the System panel has become
quite fancy. Now, not only does it tell you the OS, it
also tells of the CPU capability. So if you're running 32 bit,
and want to switch to 64 bit, it tells you whether
the CPU is 64 bit.

You can see this one is "ripe for upgrade", since the CPU is
64 bit capable.

There are two strong reasons to switch to 64 bit OS:

1) You buy a lot of brand-new Adobe software. Much of it is
now 64-bit only (Photoshop etc).

2) You have 4GB or more of RAM. If you buy 16GB of RAM, and want
to be able to use it all, Microsoft wants you to switch to a
64 bit OS to do that. Whereas, technically, PAE mode and a
32 bit OS would actually have been enough to do it. But PAE
has a few restrictions, which is why the 64 bit OS might be
preferred.

A lot of people dream about big performance gains by using
a 64 bit OS. But that only happens under limited conditions.
I had a program I wrote, that used a 32 bit or 64 bit library,
and the 64 bit library made the program run 70% faster. Normally,
that just doesn't happen, and is the exception rather than the
rule. Most programs see tiny percentage changes, when 64 bit is used.
