Two Stupid Windows 7 Questions

Since you must do a “clean “ install when upgrading from XP to 7, I am curious what would prevent one from using the upgrade version as opposed to the full version when building a new computer and saving the difference in money? The only thing that comes to mind is that at some point during the installation you are asked to enter your XP product code. If that is the case and you wanted to build a new computer and plan to get rid of your old XP one, could you use the XP product code in the same way.
Being a somewhat anal person, who plans on upgrading from Vista to 7, where does someone get the Windows 7 stick on logo to replace the Vista one that came on the front of my computer when I bought it? I thought maybe one is included in the Windows 7 box, but that does not seem to be the case.

you need a version of either xp or vista installed on the computer to use the Upgrade version.
You can have this new Windows 7 on a new partition or HDD, but it must be on the same computer for it to work

nothing,
but XP has to be somewhere on the computer @ the time of the 'upgrade' for it to work.
So really if you had one HD you'd need to partition it w/ enough space for Windows 7, install that, then delete the XP partition.

installing two operating systems on the same partition is a bad idea
leads to confusion and the potential to delete something accidentally
NVR do that

you can't upgrade an unregistered product.
