Part I: Surviving Setup
Figure 1-5: Windows Anytime Upgrade enables you to upgrade from certain Vista versions to
other, more powerful versions.
Note that you cannot upgrade Vista Home Basic or Premium to Windows Vista Business
or Enterprise. Likewise, there’s no upgrade path from Vista Enterprise to Vista Ultimate.
Purchasing a more capable version of Vista (Upgrade version) at retail and installing it
over a lesser version is the only way to migrate in these cases.
Windows Anytime Upgrade is described in more detail in the next chapter.
There are other ways to acquire Windows Vista, actually. I mentioned previously
that Microsoft sells subscription-based software through its volume licensing pro-
grams, for example. However, this book focuses on the ways in which individuals
can acquire Windows Vista.
