Windows 7 reinstall question

[mac]

I have a PC which I upgraded from vista to Windows 7 32 bit. I really
should have installed W7 64 bit instead. How can I use the same upgrade
DVD to do a clean install to W7 64 bit? Meaning use my upgrade DVD to do a
clean install over a system already upgraded (W7 over W7 with an upgrade
DVD)?

Thanks!

If you have CD's of both 32 and 64 bit then you can do what you want.

Upgrade CD's can even be used to install Windows 7 on a totally blank
hard drive if you follow the right instructions, just as you could in Vista.

Here is a link that should provide you more information.

You may need to phone in your activation, or not, depending on when and
how many times you have activated your license over the internet. The
same license key works for either 32 or 64 bit versions of Windows 7,
but it is only allowed to be actually running on one computer. No way
of telling until you try to activate the new version if you will have an
activation problem. If you do then a screen will pop up with the phone
number you will need to call to activate it.

You may need to delete the windows.old folder to save space when you are
finished (archived copy of your last installation) unless you did a
format as part of your new installation.

Going from a 32 bit OS to a 64 bit OS requires a NEW install.....no upgrade
path available.
Start with the W7 DVD ..pick new 64 bit install and follow the
prompts.......
Hope you have your work backed up.

One other thought, with missing drivers still an issue with much of
W7-64, especially if you have older hardware, you might want to run the
System Information for Windows (SIW) and print out the current hardware
listed so you can check to see if you can locate the 64 bit drivers
before you do the re-install. Might save you some trouble with the
install if you have the updated drivers already downloaded onto a flash
or other media prior to the install.

You can get a copy of the freeware program, SIW directly from the
author's site at http://www.gtopala.com/siw-download.html
