DailyTech reported on Monday that Microsoft no longer
performs disc checks during an operating system install.
In the past, when performing a clean install, a user could boot from an install
CD and insert a disc from a previous version of Windows for upgrade compliance.
However, per Microsoft's new licensing requirements for Vista, users
are required to install a Windows Vista Upgrade from within Windows XP. When
this occurs, the Windows XP license is forfeited and the Windows Vista installation
process can take place.
DailyTech has confirmed a new workaround
proposed by Paul Thurrott (via Microsoft internal documents).
This workaround allows users to perform a “clean
install.” The process is a bit tedious, but is not hard at all to complete. Users have to perform these simple steps to perform a clean install
of Vista without a previous version of Windows installed with an upgrade DVD:
There's no telling why Microsoft left this loophole wide
open with Windows Vista Upgrade DVDs, but this means that any retail upgrade
DVD can be used as a fully functioning full retail copy of Vista.

quote: The new license terms say: “You may uninstall the software and install it on another device for your use. You may not do so to share this license between devices.”
quote: Here are the practical implications of the change:
If you purchase a new computer with Windows Vista preinstalled, or if you build your own PC using an OEM version of Windows , this change doesn't affect you. Your copy is locked to that PC and cannot be transferred to another.
