I have genuine copies of XP Home and Vista Home Premium, but if I do a clean install, how does the upgrade disc know this? :S I remember with Windows 98 you had to insert a Windows 95 disc to prove you had it, but today I can imagine that this would be too easy for pirates! I have the disc for Vista Home Premium to go with the code, but not for XP Home.
I've read the stickies, but they were about upgrading, whereas I want to do a clean install!
Thanks,
Thomas.
This is a quote from one of the stickys:
"You can use the upgrade disc to replace XP with Windows 7, you just have to do a clean install.
There is a terminology conflict between Microsoft and common usage. Microsoft calls changing from an older to a newer operating system as an "upgrade" regardless of the specific procedure required. You may do an "in-place" upgrade, or you may do a "clean install" upgrade. Common usage only applies the term "upgrade" to an "in-place" upgrade. (You can perform an "in-place" upgrade from Vista to 7, but you must perform a "clean install" upgrade from XP to 7. Either of these operations can be performed from the Windows 7 upgrade disc.)
So, it is a true statement to say that you can upgrade from XP to Windows 7 with an upgrade disc, but you must do a "clean install" upgrade. You cannot, however upgrade from Windows 2000 or Windows 98 for instance to Windows 7, you would have to have a full version disc. "
You will be able to "Upgrade" Windows XP to W7, but you will have to do a clean install. There is no CD verification from XP or Vista to W7, it will simply (Clean or In-place) upgrade Vista, or it will Clean-install over a Windows XP installation. 
To do a clean install from an upgrade disc, all you'll need is a previous operating system intact... (i.e. XP or Vista) on your harddrive...
Did that kind of answer your question? <(^_^)>
