Re: Windows 7 32 bit or 64 bit

Thanks for this explanation. I'm in the fortunate position that my
consultant would do the aggravating work you describe, though I'll pay
accordingly, and of course, I'd buy a 64-bit-enabled machine. That's a
critical point I should have made in my original post.

There's a lot to consider, I don't think it is as simple as your tech leads
you to believe.

You can run a 32-bit version of Windows 7 on a 64-bit capable CPU. But, if
you then decide to upgrade to a 64-bit version of windows, you'll need to
backup your files and do a custom installation. Because of the added
benefits of being able to utilize more memory, unless you have a specific
reason where you need to stay with a 32-bit version, it just doesn't make
much sense. Most existing applications will work with Win 7 64-bit edition.
If an older app won't work, I'd be very amazed if it would work with any
version of Windows 7 at all. I think the only alternative for getting an app
that won't work in Win 7 at all to work would be to get Windows 7 Pro or
Ultimate and run it in Xp Mode. You may need to run a different
screen-reader like NVDA in XP mode, I seem to recall that there were some
difficulties running Jaws in XP mode in Win 7 professional. Now, you may
have some older hardware that may have Win 7 32-bit drivers but not 64-bit
drivers, in that case, you may want to stick with Win 7 32-bit edition.

Here is an FAQ from Microsoft which covers the differences between 32 and 64
bit editions

To address your tech's claim about being able to upgrade a 32-bit machine to
64-bit, this is correct if and only if you have a 64-bit capable CPU. You
can see if you do under the system performance tab in Vista or Win 7, or if
you use XP, just right-click the my computer icon and look under properties.
It will say 64-bit capable if it is.

Take my advice, I don't use it anyway.

Hi, Crystal.

I also haven't upgraded to Windows 7, but I've been gathering ideas for when
the time comes. Judging by what I've read and heard, we may not experience a
big difference at this time with 64-bit, but clearly it's the way of the
future, alongside Windows 7. Several listers voiced concern that some older
applications that haven't been updated for years won't function on a 64-bit
machine. I think of those useful little programs at Debbie Scales' website.
In my case, my prize computer component is a Dectalk Plus. Some listers
indicate that it should work on a 64-bit machine, but no one using a 64-bit
machine with the Dectalk has posted confirmation.

My tech consultant says that a 32-bit machine can be upgraded to 64-bit. He
has never misinformed me, so I take this statement to be true, but I don't
recall anyone posting about doing such an upgrade on the list.

Based on these considerations, when the time for me to go Windows 7 arrives,
I plan to install the 32-bit version with a view to upgrading to 64-bit when

Hi, I have Jaws 12, but have reverted to Jaws 11 as 12 was crashing too

I'm afraid I need to think seriously about a new computer.

I'm still with XP Home.

Can someone tell me what would be the major difference between Windows 7
bit or 64 bit?

Thanks. Crystal
