I have recently upgraded Windows Vista Home Premium SP2 to Windows 7 Home
Premium 32bit.

My desktop has 3.37 GB usable RAM and I am now considering doing a clean
install to 64 bit.

Is this possible using the Microsoft upgrade CD, please?

A clean install is the only way you can go from 32-bit to 64-bit. Boot
with the 64-bit disc and let it find the current installation then
delete the partition with 32-bit Win 7 and proceed from there.

The 32 and 64 bit versions are on different disks. Typically, a retail
upgrade package will contain both. OEM versions however, typically
only have one.

You need to look at your disks.

An upgrade disk that is 64-bit will allow you to do a clean install, yes. As
others have pointed out, you may only have a 32-bit disk, or you may only
have a license for 32-bit, you'll need to verify that. And you can't do an
actual in place upgrade, but must do a clean installation because of the
change in architecture.

Thanks all of you for your helpful replies.

I used the retail 64-bit retail Home Premium upgrade disk to run a clean
install without problem.
